IMPROVEMENTS IN OR RELATING TO ORGANIC COMPOSITIONS

0002The present invention relates to cleaning compositions which are useful in dry-cleaning of textiles and garments. More particularly the present invention relates to cleaning compositions useful in dry-cleaning of textiles and garments in a non-commercial environment, particularly in a domestic environment.

0003Various processes also for the individualized dry cleaning of garments in a domestic, i.e., home setting, have also been proposed in the art. These include compositions, apparatus and processes described in the following patent documents: U.S. 3,432,253; U.S.4,336,024; PCT Patent application WO 91/14038; U.S. 5,238,587; European Patent application, EP 0429172; as well as in GB Patent 1598911.

0004While these prior art documents illustrate various alternative approaches to providing techniques for dry cleaning of garments in a domestic environment, each of these techniques is not without its shortcomings and limitations, which limitations are addressed and overcome by the present applicants' invention. It is therefore among the objects ofthe invention to provide an improved dry cleaning formulation which may be used in a domestic or home dry cleaning operation. Such formulations feature good efficacy yet simultaneously feature surprisingly low amounts of volatile organic solvents; such new and improved formulations are particularly suited to be used in a domestic dry cleaning operation as they feature low amounts of volatilizable solvents. It is yet another object ofthe invention to provide a home dry cleaning kit which comprises a containment bag in conjunction with the new and improved formulations which may be provided in a carrier device which are suitable for use in the practice ofa dry cleaning process in a domestic environment.

0005Also, the present invention includes among its objects improved processes for the dry cleaning in a domestic environment particularly dry cleaning in a clothes dryer which process includes the step of applying the new and improved formulations to the soiled textile and/or garment and subsequently tumbling said treated textile and/or garment which are contained in a sealable containment bag in a dryer apparatus. According to an aspect ofthe present invention, there is provided a dry cleaning composition which is particularly useful in a domestic dry cleaning operation which comprises a liquid cleaning composition which comprises; 0.01 - 5% nonionic surfactant, 0.01 - 2.5% anionic surfacant selected from alkyl sulfosuccinates, alkyl ether sulfosuccinates, alkylamide sulfosuccinates, alkyl sulfosuccinamates, as well as salt forms thereof, 0 - 1% fluorosurfactant,

00060.01 - 7% organic solvent selected from alcohols and glycol ethers, to 100% water wherein the percentages indicated are representative of parts by weight based on the total weight ofthe cleaning composition.

0007The cleaning compositions may also include one or more optional constituents in minor amounts including for example, pH adjusting agents including acids and bases, particularly buffer compositions, fragrances and fragrance adjuvants including fragrance solubilizers, preservatives, as well as others not listed here. Such further optional constituents are typically present in only minor amounts, generally they in total comprise no more than about 2% by weight ofthe total cleaning compositions being taught herein, and typically in total are present in the present inventive compositions in amounts of about 1% and less by weight. The liquid cleaning compositions according to the present invention which are suited for use a home dry cleaning compositions include specific amounts of one or more nonionic surfactants, of which are preferred water soluble nonionic alkoxylated alcohols and alkoxylated phenols many of which are known to the art and available in nonionic surfactant preparations. Such nonionic surfactants are known to the art, and include one or more alkoxylated phenols, such as ethoxylated phenols, as well as ethoxylated and/or propoxylated alcohols formed by condensation of either an alkyl phenol or an aliphatic alcohol with sufficient ethylene oxide and/or propylene. Such ethoxylated alcohols, propoxylated alchohols and ethoxylated phenols, are well known and may be formed by condensation of an alkyl phenol, an aliphatic alcohol, or mixtures thereof, with sufficient ethylene oxide to produce a compound having a polyoxyethylene. Preferably the number of ethylene oxide units are present in an amount sufficient to insure solubility ofthe compound in an aqueous composition of this invention or in any dilution thereof. More preferably the ethoxylated alcohols and phenols are produced by condensation of about 4-16 (more preferably 8-13), moles of ethylene oxide with 1 mole ofthe parent compound (i.e. alkyl phenol or aliphatic alcohol). As known to those skilled in the art, the number of moles of ethylene oxide which are condensed with one mole of parent compound depends upon the molecular weight ofthe hydrophobic portion ofthe condensation product. The parent compounds that may be combined with the ethylene oxide may include one or more ofthe following: (A) an alkyl phenol having about 1-15, and preferably 7- 10, carbon atoms (saturated or unsaturated) in the alkyl group [including phenol, methyl phenol (cresol), ethyl phenol, hexyl phenol, octyl phenol, dicylphenol, nonylphenol, dodecylphenol, and the like]; and

0008(B) a primary, tertiary, or secondary aliphatic alcohol having about 10-20, and preferably 11-15, carbon atoms, (including decyl alcohol, dodecyl alcohol, tridecyl alcohol, hexadecyl alcohol, octadecyl alcohol, and the like).

0009Illustrative examples of these preferred water soluble nonionic ethoxylated phenols and/or ethoxylated alcohols surfactants include one or more of those available under the tradename of NEODOL , presently commercially available from the Shell Oil Company; TERGITOL, presently commercially available from Union Carbide, and POLYTERGENT, presently commercially available from the Olin Chemical Co., and IGEPAL presently commercially available from the

0012104A described to be tetramethyl decynediol dissolved in 2-ethylhexanol are very advantageouly used.

0013Preferably, the nonionic surfactant constituent is an alkoxylated alcohol constituent which even more preferably is one or more ethoxylated primary or secondary alcohols surfactant compositions.

0014The nonionic surfactant compositions, and in particular the preferred nonionic alkoxylated alcohol constituents are included in the home dry cleaning compositions in an amount ranging from about 0.01 to about 5.0 weight percent, based on the total weight ofthe home dry cleaning compositions composition. Most preferably, the nonionic surfactant composition is employed in an amount ranging from 0.05 to about 1.0 weight percent, and most preferably, from

00150.1 to 0.15 weight percent.

0016The compositions according to the invention include an anionic surfactant constituent which is selected from alkyl sulfosuccinates, alkyl ether sulfosuccinates, alkylamide sulfosuccinates, alkyl sulfosuccinamates, as well as salt forms thereof. Generally, the alkyl or acyl radical in these various compounds comprise a carbon chain containing 12 to 20 carbon atoms. Many such anionic surfactants are known to the art and are available from a variety of sources, including materials presently commercially available under the tradename ALKASURF (Rhόne-Poulenc Co., Princeton NJ) as well as those presently commerically available under the tradename MONAWET (Mona Industries, Paterson NJ).

0017Generally, this anionic surfactant constituent is a single surfactant, or is a mixture of such surfactants, and which is included in the home dry cleaning compositions in an amount ranging from about 0.01 to about 2.5 weight percent, based on the total weight ofthe home dry cleaning compositions composition. Most preferably, the anionic surfactant constituent is employed in an amount ranging from 0.01 to about 2.0 weight percent, and most preferably, from 0.01 to 1.0 weight percent.

0018Optionally but in some cases desirably the liquid home dry compositions according to the invention include a fluorosurfactant constituent. Desirably the inclusion of such a fluorosurfactant constituent improves the wetting ofthe garments or textiles being treated so to improve the penetration of the liquid home dry compositions. Any of a number of known fluorosurfactant compositions may be used, and desirably those which are low foaming are preferred. Such useful fluorosurfactant compositions are generally contain at least one fluoro- moiety. Of course, mixtures of two or more florosurfacants may be used.

0019Many useful fluorosurfactant constitutents as known to the art. By way of non-limiting example these include fluorinated and perfluorinated alkyl carboxylates, fluorinated and perfluorinated alkyl alkoxylates, fluorinated alkyl esters, perfluorinated alkyl sulfonates, fluorinated and perfluorinated alkyl quarternary ammonium iodides, fluorinated alkyl polyoxyethyelene alcohols, as well as salt forms thereof, especially ammonium, alkali and alkaline earth metal salts. An exemplary useful fluorosurfactant is that presently commercially available under the tradename FLUORAD which includes among other materials various perfluoroalkyl sulfonates, perfluoroalkyl carboxylates and well as salts thereof, and fluorinated alkyl esters. One such material is FC 170C (3M Company, Minneapolis MN), which is described as a being a fluorinated alkyl polyoxyethylene ethanol. This material Further useful fluorosurfactants include those presently commercially available under the tradename ZONYL (E.I. DuPont De Nemours & Co., Wilmington DE).

0020When present the fluorosurfactant constituent is present in an amount of up to about 1% by weight, but is desirably present in only minor amounts generally in an amount of up to about 0.01% by weight and even less. Typically, the fluorosurfactant composition has been found to be effective in dilutions of from 1 - 5000 ppm (parts per million) based on the total weight ofthe liquid home dry compositions, and amount of from about 100 - 2500 ppm have been found to be effective.

0021The compositions according to the invention include an organic solvent constituent which is selected from water soluble alcohols and or glycol ethers. Exemplary water soluble alcohols are desirably a lower alkyl monohydric alcohol including but not limited to straight chained and branched Cι_-6 alcohols which are preferred. Such alcohols, per se, are known to the art and are widely commercially available. Any water soluble alcohol, particularly the preferred Cι-₆ alcohols may be used and incoφorated into the home dry cleaning compositions being taught herein and are desirably selected so to exhibit good aqueous solubility, efficacy as a solvent for the removal of certain stains, and particularly desirably to be volatile so that once applied to the soiled garment or textile, readily volatilize therefrom.

0022The organic solvent constituent ofthe home dry cleaning compositions taught herein may also be a glycol ether solvent constituent. Preferred as the glycol ether solvent constituent according to the present invention are water soluble glycol ethers according to the general structure R_a-0-R_b-OH, wherein R_a is an alkoxy of 1 to 20 carbon atoms, or aryloxy of at least 6 carbon atoms, and R_b is an ether condensate such as ofa propylene glycol and/or ethylene glycol having from one to ten glycol monomer units. Preferred are C₃-C₂₀ glycol ethers are those having one to five glycol monomer units. Further examples of particularly preferred solvents include propylene glycol methyl ether, dipropylene glycol methyl ether, tripropylene glycol methyl ether, propylene glycol isobutyl ether, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol butyl ether, diethylene glycol phenyl ether, propylene glycol phenol ether, and mixtures thereof. Exemplary glycol ethers which may be very advantageously employed as the solvent constituent is one or more ofthe solvents ofthe group consisting of diethylene glycol methyl ether, ethylene glycol n-butyl ether, diethylene glycol n-butyl ether, ethylene glycol hexyl ether, diethylene glycol hexyl ether, and mixtures thereof. These materials are presently commercially available under the tradename DOWANOL from the Dow Chemical Co. (Midland MI); ARCOSOLV from the Atlantic Richfield Co., as well as CARBITOL or CELLOSOLVE, both from Union Carbide Corp. (Danbury CT). The organic solvent constituent may be one or more water soluble alcohols, one or more glycol ether solvent constituents, or mixtures of one or more alcohols and one or more glycol ethers. The organic solvent constituent is generally included in the home dry cleaning compositions in an amount ranging from about 0.01 to about 7 weight percent, based on the total weight ofthe home dry cleaning compositions being taught herein. However, the alcohol constituent is desirably included in lower proportions, and preferably it is utilized in an amount ranging from about 0.05 to about 5 weight percent, and most preferably, from 1.0 to 5.0 weight percent.

0023Where the organic solvent constituent includes one or more glycol ether solvent constituent is preferably employed in an amount sufficient to sufficiently solubilize the home dry cleaning compositions composition so that it is not overly viscous or gellatious in nature, but rather, exhibits a flow viscosity similar to lower alkyl alcohols or water. Generally the likelihood of forming a composition which has such a viscous or gellatious is minor due to the fact that a substantial proportion ofthe composition is water, however such a likelihood is possible and is desirably to be avoided, as lower viscosity characteristics are particularly beneficial when the home dry cleaning compositions composition is provided in a package or dispenser which includes a dispensing pump or nozzle. Also, lower viscosity characteristics facilitate the absoφtion ofthe home dry cleaning composition amongst the fibers ofa textile or garment. The desired low viscosity characteristic may be achieved in part by the careful selection of one or more glycol ether solvents with particular attention to their solubility characteristics in water, as well as their molecular weights. For example, a formulation within the present invention's scope may have it viscosity lowered by the inclusion ofa greater amount ofa lower molecular weight glycol ether solvent. At the same time, care should be taken in the selection ofthe glycol ether solvents so ensure that good stain solubilization properties, including those normally associated with higher molecular weight glycol ethers by desirably ensuring that they are included in the home dry cleaning compositions as well. Thus, with a view to these considerations the selection of a good glycol ether solvent constituent may be made experimental evaluation techniques familiar to those skilled in the art.

0024As is noted above, the compositions according to the invention are aqueous in nature, as water forms the major constituent. The water, it is preferably substantially free of any undesirable impurities such as organics or inorganics, especially minerals salts which are present in hard water which may detract from the operation ofthe one or more ofthe essential constituents according to the invention, as well as any other optional components which may be included. Water is added to in sufficient amounts so to provide 100% by weight ofthe cleaning composition. Desirably, the water forms at least about 90% by weight, and more desirably at least about 92% by weight ofthe total weight ofthe home dry cleaning compositions being taught herein.

0025As has been denoted above, the home dry cleaning compositions according to the invention may comprise one or more ofthe following optional components, the total weight of such optional constituents not exceeding about 2% by weight ofthe total weight ofthe composition, more preferably not exceeding about 1% by weight and is most preferably less than about 1% by weight based on the total weight ofthe composition. Such optional constituents may be one or more ofthe following: coloring agents, fragrances (whether natural or synthetically produced), fragrance adjuvants and/or fragrance solubilizers, viscosity modifying agents, thickeners, gelling agents, optical brightening agents, pH adjusting agents such as acids or bases and especially pH buffers, water softening agents, biocides and preservatives. By way of example but not by way of limitation, commerically available compositions useful as preservatives for the home dry cleaning compositions being taught herein include those marketed under the tradenames KATHON (Rohm & Haas Co., Philadelphia PA), DOWICIL (Dow Chemical Co., Midland MI), BUSAN (Buckman Laboratories, Memphis TN) and DANTOGARD (Lonza Chemical Co.,

0026Fairlawn NJ).

0027Such constituents as described above, including the nonionic surfactants, anionic surfactants, flurosurfactants and solvents, as well as optional constituents including those recited above are well known to the art, and are preferably selected so as not to detract from the other advantageous features ofthe inventive compositions. Such materials are described, for example in McCutcheon 's Detergents and Emulsifiers, Vol. 1, North American Edition, 1991; as well as in in McCutcheon 's Functional Materials , Vol. 2, North American Edition, 1991, the contents of which are herein incoφorated by reference.

0028The present inventive compositions have suφrisingly been found by the inventors to be excellent cleaners to perform well as a cleaning composition for use in a domestic dry cleaning process as is to be described in more detail below. This is particularly surprising as water is found to be a major constituent ofthe composition, and that only minor amount of surfactants and other solvents are present, yet good dry cleaning effects have been observed. The present inventive compositions have also been found by the inventors to leave little, but generally no residues or residual marks on treated garments; residues or rings which have been known to the art and are typically attributed to the surfactants contained in such prior art compositions. The present inventive compositions have also been found to be good general cleaning compositions on a wide variety of textiles, such as wool, cotton, synthetic fibers such as rayon, and silk which is particularly difficult to dry clean. In accordance with a particularly preferred embodiment ofthe invention, there is provided home dry cleaning composition consisting essentially ofthe following constituents: 0.01 - 2.5%wt. nonionic alkoxylated alcohol, 0.01 - 2.5% wt. anionic surfactant selected from alkyl sulfosuccinates, alkyl ether sulfosuccinates, alkylamide sulfosuccinates, alkyl sulfosuccinamates, as well as salt forms thereof, 0 - 0.1 %wt. fluorosurfactant, 0.01 - 7%wt. organic solvent selected from alcohols and glycol ethers, 0 - l%wt. optional constituents, to 100%wt. water.

0029By way of nonli iting example, such optional constituents include one or more selected from pH adjusting agents such as buffers and acids or bases, fragrances, fragrance adjuvants and solubilizers, preservatives, coloring agents, and optical brighteners.

0030The present inventive compositions may be simply produced as by mixing measured amounts of individual constituents to form a homogenous mixture therefrom. This may be done by well known techniques, and is desirably done in a simple paddle mixer, stirrer or other low shear liquid mixing apparatus so to avoid undesired foaming ofthe compositions.

0031In accordance with one aspect ofthe process according to the invention, a soiled garment is treated by applying an effective amount ofthe cleaning composition directly to the surface of the garment. This can be done in one or more ofthe following ways and such an application can take place in a number of forms and using a number of devices. For example, in accordance with one embodiment ofthe invention, the cleaning composition is provided to the consumer in a conventional dispenser such as a spray bottle, squeeze bottle, aerosol, or other dispensing container. In such a way, application ofthe cleaning composition is possible by the requisite pumping ofthe spray bottle, alternately squeezing and dispensing the cleaning composition from the squeeze bottle or in a further alternative by spraying from the pressurized aerosol container the cleaning composition. After an effective amount ofthe cleaning composition has been applied to the surface of one or more garments to be treated, the treated garment is then introduced into the interior ofa containment bag. The garment may be introduced singly or can be in conjunction with other articles to which the cleaning composition has been applied in a similar fashion, or in conjunction with other articles which have not been contacted with the cleaning composition according to the invention. Subsequently, the containment bag is sealed so to retain the one or more articles wherein, and then the sealed contaiment bag with its contents are introduced into the interior ofa domestic dryer apparatus. Various constructions for the sealable containment bag are described in more particular detail below. Optionally, localized stains may be cleaned separately by the consumer using a spot cleaning composition prior to the application ofthe liquid cleaning compositions being taught herein. Such spot cleaning compositions include those known to the art, and include for example one or more ofthe compositions referenced in the prior art patents denoted above. A spot cleaning composition may be advantageously employed to clean hard to remove as well as localized stains on the garment to be treated.

0032A particularly advantageous spot cleaning composition is one comprising the following constituents: 0.1 - 10%wt. nonionic alkoxylated alcohol; 0.1 - 10%wt. nonionic alkoxylated mono- and di-alkanol amide; 0.1 - 3.5%wt. anionic surfactant especially one or more selected from alkyl sulfosuccinates, alkyl ether sulfosuccinates, alkylamide sulfosuccinates, alkyl sulfosuccinamates, as well as salt forms thereof; 0 - l%wt. flurosurfactant; 0.01 - 7%wt. alcohol solvent especially water miscible alcohols; 0.01 - 30%wt. glycol ether solvent, especially water miscible glycol ethers; to 100%wt.water. Optionally, this spot cleaning compositions may include up to about 2%wt. of one or more conventional additives such as acids, bases, pH buffers, coloring agents, fragrances and the like. Desirably, these spot cleaning compositions comprise at least about 70%wt. water. This advantageous spot cleaning composition is very effective in the removal of localized stains, leaves no discerible deposits or residues when used prior to an in conjuction with the cleaning composition being taught herein, and contain a relatively minor proportion of volatile organic compounds as these spot cleaning compositions desirably contain at least about 70%wt. water.

0033Typically in accordance with the processes according to the invention, dryer apparatus including those having a rotating drum which rotates about a horizontal axis, but in some cases includes a drum which rotates about a vertical or other non-horizontal axis and such may be also used. Generally, those having a drum which rotates about an approximately horizontal axis are preferred. Such horizontally rotating drum ensures a good tumbling effect to the articles within the sealed containment bag and aids in the effective and uniform distribution ofthe cleaning composition amongst the surfaces ofthe garments being treated.

0034Subsequent to its introduction ofthe sealed containment bag into the dryer apparatus, the dryer apparatus is actuated and optionally, heated for sufficient time to allow the tumbling ofthe treated garment and to distribute the cleaning composition onto the garment or textiles being treated. As an alternative process and dependent upon the available modes of operation ofthe dryer apparatus, after the introduction ofthe sealed containment bag containing the garments to be treated, the rotating drum is actuated to operate for several minutes without the application of heat to the rotating drum which permits tumbling ofthe containment bag and the distribution ofthe cleaning compositions ofthe instant invention more uniformly to the garments within the sealed containment bag prior to the appreciable volatilization ofthe cleaning compositions. Subsequent to this process step, the dryer apparatus may then be actuated to apply heat to the rotating drum and its contents so to volatilize at least a major portion ofthe cleaning composition. Subsequently, the treated garments may be removed and are optionally subjected to further treatment steps such as ironing, pressing and the like. The treated garments or textiles are typically damp to the touch following this treatment step.

0035If desired, the thus treated garments and textiles may be treated with a fabric treatment composition such as a sprayable fabric softening composition, or an antistatic composition. The liquid cleaning compositions being taught herein are advantageously used in a process for home dry cleaning wherein one or more garments or textiles are provided into the interior ofa containment bag with a quantity ofthe compositions, the bag is then closed and inserted into a clothes dryer and the containment bag and its contents are tumbled to ensure the distribution ofthe liquid cleaning composition to the garments or textiles. The dryer dry cleaning and freshening system shown in Fig. 1 includes a containment bag having an opening conveniently placed at one side thereof. With reference to containment bag it may be fabricated ofa material which is vapor impermeable material such as a plastic or polymer material such as from a sheet or film which is sewn, as well as certain non-woven textiles and formed materials, such as T NEK (DuPont Coφ., Wilmington DE) and the like. Such a containment bag is typically sealed or otherwise fastened on one or more edges in order to form said containment bag, and any conventional means for its production may be used. Such sealing or fastening means include for example sewing, welding, melt-bonding as well as other conventionally known means. It is further to be understood that while a vapor impermeable material may be used in the construction ofthe containment bag, it is to be understood that such a bag itself need not be totally hermetically sealable itself and that the escape of vapors or gases from within such a containment bag to its exterior, such as the interior space of a clothes dryer is to be foreseen. Such an escape of vapors may occur at seams of said containment bag, particularly where sewn seams are present, as well as from the sealable opening. Alternately, the containment bag may be fabricated ofa material which is vapor permeable, such as a woven or non-woven textile material, which may be made of naturally occurring or synthetically produced fibers, as well as blends of two or more different materials. Both the vapor permeable materials and the non-vapor permeable materials may be a single layer material, or may be of a multilayer construction such as two or more layers of differing materials layered in register. Examples of such include a first layer of a non-woven material which is used in the innermost layers ofthe containment bag, which is in turn layered with a non-woven material such as a polymer film layer which desirably provides a vapor impermeable barrier layer to the containment bag. A second example of multilayer containment bag constraction includes a first innermost layer which is a fibrous material, such as a non-woven material and a second layer in register therewith of a non-woven vapor impermeable synthetic paper-like material such as TYNEK material which is used to form the exterior ofthe containment bag. Such a construction provides the advantage of providing a vapor impermeable containment bag, which has a durable exterior layer which in turn increases the operating life of such a containment bag. Further, the exterior material made of TYVEK or a similar material is readily printable using known art techniques which permits the printing ofa legend, logo or instructions for use on this exterior surface ofthe containment bag. A third preferred material of construction useful in the fabrication ofa containment bag is a two or three layered construction, wherein the first and innermost layer ofthe containment bag is of a non- woven, fibrous material such as ofa synthetically produced fiber, which in turn in bonded to a second spun bonded polymeric textile material, which imparts strength to such a containment bag construction. Optionally, but desirably a third layer ofa non-woven, fibrous material is bonded to the remaining side ofthe spun bonded polymeric textile material and thus forms the exterior ofthe containment bag. The fibrous material used in the formation of this third layer may be ofthe same synthetically produced fiber ofthe first, innermost layer or it may be ofa different fiber.

0036A further and most preferred material of construction for the fabrication ofthe containment bag is a vapor impermeable or poorly vapor permeable bilayered material which has on its first layer a polymeric film, which is bonded to a second layer of a polymeric spun bonded nonwoven textile material. Both the polymeric film and the polymeric spun bonded nonwoven textile material may be produced from a variety of known art polymers and copolymers including for example nylons, polyalkylene terephthalates, rayon, as well as polyalkylenes especially polyethylene, polypropylene and polybutylene being of particular advantage due to their low cost and ready fabrication into both vapor impermeable films as wall as nonwoven textile materials. The bonding between these layers may be accomplished by virtually any known means, including for example heat bonding, resin bonding which may require the use ofa bonding material or film intermediate to the first film layer and second film layers, as well as ultrasonic bonding methods which provide effective binding between these two materials and which may be practiced to produce an attractive dimpled appearance on the final material. In accordance with this most preferred embodiment, the containment bag is constructed such that the first film layer is forms the interior ofthe containment bag and thereby, and the second film layer forms the exterior ofthe containment bag. A first advantage of this most preferred containment bag construction is that the interior film layer ofthe bag is both vapor impermeable and is nonabsorbent ofthe liquid cleaning composition and thus the maximum cleaning efficacy of these compositions is available to the clothes or other textiles being treated in the process according to the invention. A second advantage ofthe preferred constraction is the inventors' observation that such a containment bag billows sufficiently during the tumbling and heating it encounters in the dryer apparatus, yet permits the escape of vapors produced or entrapped within the containment bag to escape at an acceptable rate. A third advantage enjoyed by the preferred construction is the durability of such a containment bag as the nonwoven film layer which forms the exterior ofthe bag is resistant to tearing, and at the same time the soft tactile characteristics of this layer make the bag especially attractive from the standpoint of the consumer.

0037Other advantageous materials of construction for the fabrication of containment bags 1 which are alternative especially preferred embodiments having a vapor impermeable or poorly vapor permeable bilayered material which has on its first layer a polymeric film, which is bonded to a second layer of a textile material include for example: a first vapor impermeable layer of a copolymer film for a film formed from a blend of polymers including for example: polyethylene terephthalate - polybutylene terephthalate; polyethylene terephtalate - rayon which are in turn bonded to second layer ofa polymeric nonwoven textile material which may be for example: rayon, and spun bonded or melt blown polyethylene or polypropylene textile materials. Such materials of constraction useful for the fabrication of containment bags 1 which may be produced from these immediately above recited include: a first layer of a polyalkylene film, such as polyethylene or polypropylene bonded to a second layer ofa textile material based on a blend of rayon and polyethylene terephthalte; and, a first layer ofa polyalkylene terephalate film, bonded to a second layer of a rayon textile material.

0038It is to be understood that in any ofthe constructions recited which include one or more polymeric materials, that minor amounts of conventional additives may be included in conventional amounts including but not limited to: colorants, heat stabilizers, ultraviolet stabilizers and filler materials. Such are, per se, known to the art.

0039Both the first layers and the second layers may be ofthe same or different thicknesses, and it is required only that the containment bag formed from these materials be flexible. Most desirably however, the thicknesses of both the first and second layer are less than about 20 mils, more desirably the thickness ofthe first, preferably vapor impermeable layer is 5 mils and less, especially 3 mils and less, while the thickness ofthe second layer and any further layer is about 5 mils and less. The dimensions ofthe containment bag and its internal volume may vary considerably. Desirably however, the containment bag is sufficiently large to contain at least one garment or textile to be treated, but preferably 2 - 3 such garments, as well as the absorber means being taught herein, while at the same time not be overly large and thus be inconvenient for use in a domestic dryer apparatus. Advantageously the containment bag has a volume of about 75 litres or less, with sizes of about 50 liters, and about 30 liters being preferred.

0040The opening ofthe containment bag is conveniently located at an edge ofthe containment bag, but it may be located elsewhere.. The opening may be a simple slit or discontinuity in the material ofthe bag's construction or it may take a more complex form such as further including a foldable flap to close the bag, or may also use fastening means. Suitable fastening means may be any useful fastening means known to the art including, but not limited to one or more ofthe following: zippers, hook-and-loop type fasteners (VELCRO®), buttons, clips, pins, snaps, adhesive strips, as well as resealable plastic sealing elements such as two strips, one on each margin ofthe opening when pressed together interlock to form a flexible seal. Such resealable plastic sealing elements are known to the art dealing with plastic bags and pouches, and are sometime referred to as ZIP-LOCK® type closures. Suitable fastening means also includes the use of a simple drawstring to pull the opening shut, the use ofa single deformable wire-type "twist tie" to close the opening, as well as the use of one or more fastening means in conjunction with a flap. Further conventionally known fastening means although not elucidated here may also be used. In accordance with the convenient placement ofthe opening at or near an edge ofthe containment bag, the fastening means is placed at or about the edge ofthe bag as illustrated on Fig.1. It is only required that the selected fastening means be affixable onto the materials of construction used to fabricate the containment bag, and that it form a relatively secure closure. Desirably, the containment bag is closeable to provide a liquid seal to minimize the leakage of any liquid cleaning composition out of said bag and into the dryer, which in turn ensures that maximum cleaning effect is imparted to garments or other textile materials being treated

0041In a containment bag construction, the use ofa fibrous material to form the innermost surface ofthe containment bag may be desired as such a fibrous material is suited to entrap and entrain particles which may be released from a garment or textile being cleaned and/or absorbing ofthe cleaning composition being provided herein. Such a containment bag may be desired as they may be amenable to laundering by the consumer. Following such a laundering operation, the entrained/entrapped particulates, soils, as well as any residual cleaning composition may be removed from the containment bag and as such, the bag may be reused in a further dry cleaning operation. One alternative embodiment ofthe process according to the instant invention, the cleaning compositions are used in conjunction with a dispensing container, or other container, which contains the cleaning composition as well as an absorbent sheet. Such absorbent sheets may be produced from any fibrous or cellular flexible material which exhibits sufficient thermal stability for use in a clothes dryer. For example, such sheets may be non-woven materials such as those which have bonded fibers in a web accorded fiber structure and/or those which comprise fibrous mats in which the fibers are distributed in a random array. Such a fibrous can be naturally produced fibers including wool, silk, cotton, linen, hemp, sisal, ramie or may be synthetically produced such as synthetically spun fibers of polymers. Examples of such synthetic fibers include rayon, cellulose, polyvinyl derivatives, polyolefins, polyesters, as well as polyamides. Of course, mixtures of two or more different fibers may be used in the production of such non- woven materials. Preferably such sheets are sufficiently strong such that they will resist tearing or separation when used in a clothes dryer as described in the processes taught herein. These sheets, when used, may be of any dimension but are preferably sheets having an area of at least-one square centimeter and greater. Sheets having larger areas, i.e., those having areas of at least 50 square centimeters and greater are preferred from the view point of ease of use and handling. Such larger sheets are generally preferred as subsequent to the home dry cleaning processes being taught herein. They may be readily separated from the treated garment and easily discarded. From this perspective then it is clear that an overly large sheet such that which would resist the tumbling operation ofthe garments being treated and/or would tend to clump or bundle during the tumbling operation ofthe clothes dryer are to be desirably avoided. As a function ofthe sheet is to act as an absorbent substrate for the cleaning composition and/or to act as a transport vehicle wherein cleaning composition absorbed upon the surface ofthe sheet may tumble and ultimately recontact a different region ofthe garment or textile material to be treated. In view ofthe foregoing then it is preferable that an intermediate size sheet and/or a plurality of intermediate sheets, preferably those having an area of at least about 50 square centimeters are to be used.

0042In accordance with a further aspect ofthe invention, there is provided a system optionally in kit form which includes a containment bag as described above, a quantity the liquid cleaning composition as taught herein, and a dispenser means. Such a dispenser means may be a ball- shaped dispenser which may be separated into hemispheres and which includes in one ofthe hemispheres a vessel for the containment ofthe cleaning composition taught herein in a measured amount. The vessel also includes a fluid communication means such as one or more perforations, preferably small perforations and/or a semi-permeable wall or sealing cap which permits for the flow ofthe cleaning composition from the interior ofthe vessel to the exterior ofthe dispenser such that it may be contacted with a garment or textile. The advantage of such a dispenser is that it may be produced as both a single use dispenser and disposed after a single dry cleaning operation or it may be produced as a refillable and multi-use dispenser wherein the consumer may refill the dispenser between dry cleaning operations. The dispenser may also be produced as a refillable dispenser.

0043In yet a further embodiment ofthe invention there is provided a system, optionally in kit form which includes a containment bag as described above, a quantity the liquid cleaning composition as taught herein, and a dispensing container. The dispensing container may take a variety of forms, including a variety of known devices including resealable bottles with or without dispensing elements such as manually pumpable dispensers, bottles or flasks supplied with flow directing nozzles, as well as being supplied with recloseable caps. Aerosol type dispensing containers may also be used. The dispensing containers may also be of known single opening types, including sealed pouches or packages wherein the package's integrity is destroyed once it is opened and the complete contents are expected to be used subsequent to opening. Such include, for example sealed pouches formed of single layer or multilayer constructions, particularly constructions which utilize one or more polymeric films, as well as single opening ampoules, flasks or vials which once opened are not designed to be readily recloseable. Single use dispensing containers are advantageously used as they permit for the packaging of controlled amounts ofthe cleaning compositions being taught herein which are subsequently to be used by the consumer.

0044In accordance with a further aspect ofthe invention, there is provided a system optionally in kit form which includes a containment bag as described above, a quantity the liquid cleaning composition as taught herein, and a dispenser means.

0045An exemplary dispenser means is one which is formed ofa porous material which is suited to be impregnated with the liquid cleaning composition according to the invention. In one aspect according to this embodiment, the porous dispenser may be one or more spherical or other generally ball-shaped dispensers formed ofa porous material which is adapted for the retention of the cleaning composition within, yet when subjected to sudden motion and agitation such as is expected in a drying apparatus, release their impregnated cleaning composition. Of course, other configurations such as disks, cubes, or other geometries are also useful and may be produced, however a spherical geometry is preferred as being least likely to be undesirably snagged or trapped by tumbling garments or textiles during the cleaning process where it is present within the containment bag which assures the likelihood that a more even delivery ofthe cleaning composition to the garments and textiles occurs. Such a dispenser being of a porous nature permits for the flow ofthe cleaning composition from its interior to the exterior ofthe dispenser, i.e., its surface such that it may deliver the cleaning composition to a garment or textile by physical contact therewith. Materials which may be used for the production of such a porous dispenser include foamed polymeric materials which are resilient and flexible, as well as certain porous but less resilient constructions formed from polymeric materials, such as may be formed by sintering polymeric material. Useful polymers for such constructions may be based on virtually any polymer which may be formed into such a porous dispenser means, of which polyolefins, and polyamides, especially polyalkylenes including polyethylene, polybutylene and polypropylene are advantageously used. Porous dispenser means may be produced by sintering a quantity of comminuted polymer particles, such as in the forms of pellets, powders, prills or the like under appropriate conditions to agglomerate the polymer particles into a formed article which nonetheless retains a porous nature. An especially useful polymer for this puφose is a polyolefin such a high density polyethylene which is readily commercially available at a reasonable cost, and which is readily sinterable to form such a porous dispenser. It is to be understood however-, that other polymers may be used.

0046The advantage of such porous dispenser means are that they may be produced as both a single use dispenser and disposed after a single dry cleaning operation or it may be produced as a refillable and multi-use dispenser wherein the consumer may refill the dispenser between dry cleaning operations by reimpregnating the porous dispenser with the cleaning composition such as by immersing the dispenser in a volume of said cleaning composition. Such systems which include a containment bag as described above, a quantity the liquid cleaning composition as taught herein, and porous dispenser means.

0047In accordance with a yet further aspect ofthe invention, there is provided a system optionally in kit form which includes a containment bag having an absorbent interior surface as is described above, a quantity the liquid cleaning composition as taught herein. In accordance with such a system, the liquid cleaning composition is provided to the absorbent interior ofthe containment bag and the containment bag is further provided with one or more textiles or garments to be treated in accordance with the process being taught herein. The absorbent interior which is advantageously a fibrous or fleecy material acts both to distribute the liquid cleaning composition to the garments and the to trap or entrain loosened soils from the treated garments.

0048As used throughout this specification and in the claims, the use ofthe terms "garments" and "textiles" are used to describe for example finished articles such as pants, shirts, blouses, scarves, other articles of clothing, apparel, coats, and the like. In the case ofthe former term, while in the case ofthe latter term, textiles which are produced but have not been as of yet produced into either pieced goods or finished articles such as articles of clothing or apparel is intended to be meant by the latter term. In either case, as the present invention is equally applicable and useful without distinction or regard for both textiles and/or garments, they are to be understood as to interchangeable terms with respect to the cleaning operations and cleaning compositions according to the instant invention.

0049What is to be understood by the term as "dryer" or "dryer apparatus" is a rotary dryer which generally is typical ofa domestic rotary dryer. The only requirement is that the drum be configured so as to retain garments and/or textiles therein, to be rotatable, and that the interior of the drum may be heated to at least the temperature at which the lowest boiling point constituent volatilizes. Domestic clothes dryers, as well as commercial clothes dryers, particularly ofthe rotary type and most particularly those which rotate about a non-vertical axis are to be clearly understood as encompassed within the scope ofthe instant invention.

0050As used throughout this specification and claims, references to "parts by weight" and "weight percent" and "%wt." are considered to be interchangeable and to represent the weight percent of a particular constituent with reference to a total composition within which it is included, where such total composition is considered to have 100 parts by weight. In accordance with the immediately preceeding description, all ofthe constituents of each ofthe formulations described in the examples below are recited in parts by weight and are based on 100 parts by weight ofa particular formulation, unless specified to be otherwise.

0051Examples:

0052To demonstrate the compositions according to the invention, various formulations were prepared having the constituents which are indicated on Table 1 below wherein the amounts given are the weight percent of each respective constituent. Preparation ofthe formulations were performed in a routine manner, which was generally in accordance with the following protocol. To a large glass beaker placed on a magnetic stirrer apparatus was added less than the total amount, or the total amount of deionized water. The temperature ofthe water, as well as that ofthe remaining constituents was approximately room temperature (=68°F, =20°C) The stirrer apparatus was activated, and to the water was added measured amounts of each ofthe constituents. While order of addition ofthe constituents is not believed to be important, generally the surfactants are preferably added first. After the addition of the final constituent, the contents ofthe beaker were allowed to stir for a period of 5 to 15 minutes to ensure homogeneous mixing and the production ofa uniform formulation. Each ofthe formulations was observed to be shelf stable for period of weeks and months.

0079Utilizing the example formulations described in detail on Table 1, cleaning tests were performed in order to evaluate their efficacy.

0080Cleaning Example 1 An evaluation ofthe properties ofthe formulation according to Example 6 was performed in accordance with the following general protocol. A clean off-white 100% silk blouse as stained in with 0.003 grams ofa lipstick composition. The stain was permitted to set for 15 minutes so to simulate an actual consumer staining condition. Subsequently, a clean disposable paper towel was laid on a hard nonabsorbent surface and the stain was laid facing the paper towel. A quantity ofa spot cleaning composition according to the particularly advantageous spot cleaning composition described above was applied to the silk fabric surface using an absorbent tipped dispenser in a brush stroking fashion to impart linear strokes. In such a fashion, the major portion ofthe spot cleaning composition was supplied to the locus ofthe stain and lesser amounts ofthe spot cleaner were supplied to the edges beyond the stain. In such a manner, a "feathered" application ofthe spot cleaning composition was provided. It is to be noted that a circular or swirling application pattern was not applied to the blouse in order to minimize the likelihood of deforming the textile. The spot cleaning composition was applied in such a manner until a substantial portion ofthe lipstick stain was loosened and transferred to the paper towel, and the silk blouse inspected. A minor amount ofthe lipstick was observed to still be present at the location ofthe stain.

0081Immediately subsequent, a quantity ofthe formulation according to Example 6 was applied to evenly wet the area ofthe lipstick stain and the thus treated garment was supplied to the interior ofa containment bag formed of a vapor impermeable material. The bag was sealed, and inserted into the interior ofa horizontally rotating domestic dryer apparatus. The said apparatus was activated to operate on a "low" cycle for 30 minutes, and the containment bag and its contents were removed. The silk blouse which had an overall moist appearance was then hung on a hanger and permitted to dry. Inspection ofthe location ofthe treated stain revealed no discernible stain or residue.

0082The thus treated silk blouse could be lightly ironed subsequent to cleaning in order to remove any wrinkles from the garment.

0083It is to be understood that other, spot cleaning compositions, may be used in place of that utilized above. It is further to be understood that the process as described could be performed on a garment or textile without a spot cleaning treatment step wherein a general cleaning and freshening effect is desired.

0084Cleaning Example 2 The efficacy ofthe liquid cleaning composition according to the invention and the process described above was evaluated in a process wherein the "freshening" ofa garment was a primary objective to be desired.

0085According to this example, two identical ladies' blouses made ofa 60% acetate/40% rayon blend were utilized. To the interior of first a containment bag formed ofa single layer vapor impermeable polymer film were provided a small amount, i.e., "two squirts" from a hand- holdable trigger dispenser, of an aqueous 0.2% isovaleric acid composition which was provided to simulate body odor. To a second identical containment bag, a identical amount ofthe aqueous acid composition was also provided. Subsequently one of each blouses were provided to the interior ofthe containment bags which were thereafter sealed. The blouses were allowed to remain in these bags for a period of 10 minutes; this allowed for the conditioning ofthe blouses with the acid composition such that the blouses became malodoured.

0086As a "comparative" example, one ofthe blouses was removed, introduced into a second new containment bag ofthe same a single layer vapor impermeable polymer film construction which was subsequently sealed. Afterwards this containment bag and its contents were provided to the interior ofa domestic dryer apparatus which was operated for 20 minutes on a "fluff' cycle; no heat was applied. The containment bag was then removed, its contained blouse was also removed and the blouse was laid on a hard surface from whence it could be compared by a panel of individuals as to its appearance and odiferous characteristics.

0087The second blouse was removed from the bag containing the acid composition and it was introduced into the interior of a new containment bag ofthe same a single layer vapor impermeable polymer film construction as used to produce the comparative example blouse. To this containment bag was also provided a single, approximately 2-1/2 inch square, compressible polymeric foam cube which had been provided with 30.03 grams ofa liquid cleaning composition according to Example 12, after which the containment bag was sealed. In a like manner to that described with reference to the comparative example blouse, the containment bag and its contents were inserted into the interior ofa dryer apparatus which was operated for 20 minutes on the same fluff cycle after which the containment bag and its contents were removed. During this step, it was observed that the containment bag was found to billow, and its contents was effectively tumbled within After opening ofthe containment bag, the blouse was removed from said containment bag and laid side-by-side with the comparative example blouse for comparison of its visual and odiferous characteristic. The foam cube was removed and it was determined that consequent to the 20 minutes of tumbling, that it had released approximately 59% ofthe liquid home dry cleaning composition which it had originally contained, namely 17.69 grams of its liquid cleaning composition, which was further apparent from the appearance ofthe blouse which was damp to the touch.

0088These two blouses were compared; and it was observed that the blouse treated with the composition according to Example 12 had a significantly reduced level of malodor than the first, control blouse.

0089Cleaning Example 3 An evaluation ofthe properties ofthe liquid cleaning compositions according to the formulation of Example 13 was performed in accordance with the following general protocol. A clean white rayon blouse was applied at one location with 3 grams ofthe particularly advantageous spot cleaning composition described above, which was applied with a pipette. The spot cleaning formulation was allowed to spread and thus formed a wetted circular area. The spot cleaning formulation was then manually worked in by stroking it in using a clean absorbent paper towel so to ensure that it was well interspersed among the fibers ofthe white rayon blouse. Subsequently, a small quantity ofa liquid cleaning composition according to Example 13 was applied to this wetted area as well as in the surrounding area with a hand-holdable bottle with a manually pumpable spray dispenser bottle so to wet both the area treated by the spot cleaning formulation and its surrounding vicinity. Subsequently, the thus treated blouse was inserted into the interior ofa containment bag which was formed ofa single-layer polymeric material which was then sealed, and it with its contents were inserted into a domestic dryer. The dryer was operated on a "low" setting for 30 minutes where it was observed that the bag was found to billow, and the white rayon blouse was effectively tumbled within.

0090The bag was then removed, and the blouse was withdrawn and observed. The blouse was damp to the touch, and it was observed that no yellowing or any residual deposits were discernible in the area of application ofthe spot cleaning composition.

0091Cleaning Example 4 An evaluation ofthe properties ofthe formulation according to Example 14 as utilized in the process described above was evaluated in accordance with the following general protocol.

0092A clean red-colored knitted sweater, having a fiber content of 70% lambswool, 20% angora, and 10% nylon, and indicated by the manufacturer as "dry clean only" on its label was laid on a hard flat surface. To four non-contiguous regions ofthe sweater were applied 0.2 grams ofa liquid make-up composition, 0.0015 grams ofa lipstick composition, 0.10 grams ofa tomato sauce composition and 0.10 grams ofa salad dressing compositions. These stains were permitted to set in to the garment overnight.

0093As a control evaluation, a duplicate garment as described above, i.e., a "control sweater", was stained in the same manner and likewise these stains were permitted to set overnight.

0094The following morning, the control garment was sent off to a commercial dry cleaning establishment where it was processed according to convention methods and returned at a later date.

0095The remaining sweater was laid with the stained surface down upon laying of absorbent paper towels and through the obverse side, or back side ofthe sweater from the stained areas were applied a sufficient quantity ofa spot cleaning composition according to the especially preferred spot cleaning composition described above. This spot cleaning composition was applied utilizing an absorbent tip dispenser in a brush stroking fashion to impart linear strokes; application ofthe spot cleaning composition continued until it was observed that substantially all ofthe stains were removed from the stained garment and transferred to the clean paper towel which acted as an absorbing and stain entraining substrate It is to be noted that cleaning the stains using the spot cleaning composition through the obverse side ofthe sweater did not force the migration ofthe soil or stain through the textile, but rather forced the stains directly from the sweater's surface to the surface ofthe paper towel.

0096Subseqently was provided a single, approximately 2-1/2 inch square, compressible polymeric foam cube which had been provided with 29.83 grams ofa liquid cleaning composition according to Example 14 described above. This liquid cleaning composition was ideally suited for the home dry cleaning process described herein. This cube was lightly dabbed in the regions ofthe areas wherein the spot cleaning composition had been applied, particularly at the peripheries thereof in order to "feather" these wetted areas. Immediately thereafter, the cube and the thus treated red sweater was inserted into a containment bag formed of a non-vapor permeable material which was then sealed. The sealed containment bag and its contents were then inserted into the interior of a domestic dry cleaning apparatus which was then operated on a "fluff ' cycle for 20 minutes to allow the tumbling of both the red sweater and the liquid cleaning composition entrained polymeric foam cube during this interval. During this time, no heat was applied to the new bag or its contents by the dryer apparatus, and the containment bag was observed to expand or billow which permitted effective tumbling ofthe foam cube and the contained red sweater.

0097Subsequently, the containment bag was withdrawn from the dryer apparatus its contents were also removed and examined. It was observed that 53%wt. (or 15.76 grams) ofthe liquid cleaning composition of Ex. 14 had been released from the cube during the treatment process. The visual appearance and the odiferous characteristics of this thus cleaned red sweater were observed. It was noted that no shrinkage or color change was apparent to this garment, but that it was damp to the touch. It was also observed that each ofthe four stains formed by the liquid make-up, lipstick, tomato sauce and salad dressing were all totally removed and further that there were no discernible residues or residual fronts from the stained spot cleaning composition. While the sweater was slightly damp to the touch, it did not require ironing and could be hung to dry on a conventional clothes dryer. No unpleasant scent was observed.

0098This sweater was compared to the control sweater which had been cleaned by a conventional dry cleaning establishment. Also, no shrinkage or color change was observed in this garment, and the four stains were also effectively removed. By comparison, it can be seen then that the use ofthe liquid compositions and the processes being taught herein are very favorably comparable to that which is provided by a conventional dry cleaning apparatus, but notably the compositions and processes ofthe invention may be practiced by a consumer in a much shorter span of time and in the convenience and approved sanitary environment of their own dryer apparatus. Cleaning Example 5 An evaluation ofthe properties ofthe formulation according to Example 14 as utilized in the process described above was evaluated in accordance with the following general protocol. A clean white blouse, having a fiber content of 6% acetate and 40% rayon and designated by the manufacturer as "dry clean only" on its label was laid on a hard flat surface. To four non¬ contiguous regions ofthe sweater were applied 0.2 grams ofa liquid make-up composition, 0.0015 grams ofa lipstick composition, 0.10 grams ofa tomato sauce composition and 0.10 grams of a salad dressing compositions. These stains were permitted to set in to the garment overnight. As a control evaluation, an identical clean white blouse as described above, i.e., a "control blouse", was stained in the same manner and likewise these stains were permitted to set overnight.

0099The following morning, the control blouse was sent off to a commercial dry cleaning establishment where it was processed according to convention methods and returned at a later date. The remaining blouse was laid with the stained surface down upon laying of absorbent paper towels and through the obverse side, or back side ofthe sweater from the stained areas were applied a sufficient quantity ofthe especially advantageous spot cleaning composition described above. This spot cleaning composition was applied utilizing an absorbent tip dispenser in a brush stroking fashion to impart linear strokes; application ofthe spot cleaning composition continued until it was observed that substantially all ofthe stains were removed from the stained garment and transferred to the clean paper towel which acted as an absorbing and stain entraining substrate It is to be noted that cleaning the stains using the spot cleaning composition through the obverse side ofthe sweater did not force the migration ofthe soil or stain through the textile, but rather forced the stains directly from the sweater's surface to the surface ofthe paper towel. Subseqently was provided a single, approximately 2-1/2 inch square, compressible polymeric foam cube which had been provided with 29.61 grams ofa liquid cleaning composition according to Example 14 described above. This liquid cleaning composition was ideally suited for the home dry cleaning process described herein. This cube was lightly dabbed in the regions ofthe areas wherein the spot cleaning composition had been applied, particularly at the peripheries thereof in order to "feather" these wetted areas. Immediately thereafter, the cube and the thus treated blouse was inserted into a containment bag formed ofa non- vapor permeable material which was then sealed. The sealed containment bag and its contents were then inserted into the interior of a domestic dry cleaning apparatus which was then operated on a "fluff cycle for 20 minutes to allow the tumbling of both the blouse and the liquid cleaning composition entrained polymeric foam cube during this interval. During this time, no heat was applied to the new bag or its contents by the dryer apparatus, and the containment bag was observed to expand or billow which permitted effective tumbling ofthe foam cube and the contained blouse.

0100Subsequently, the containment bag was withdrawn from the dryer apparatus its contents were also removed and examined. It was observed that 57%wt. (or 16.81 grams) ofthe liquid cleaning composition of Ex. 14 had been released from the cube during the treatment process. The visual appearance and the odiferous characteristics of this thus cleaned blouse were observed. It was noted that no shrinkage or color change was apparent to this garment, but that it was damp to the touch. It was also observed that each ofthe four stains formed by the liquid make-up, lipstick, tomato sauce and salad dressing were essentially totally totally removed and further that there were no readily discernible residues or residual fronts from the stained spot cleaning composition. While the sweater was damp, almost moist to the touch, but did not require ironing and could be hung to dry on a conventional clothes dryer. No unpleasant scent was observed. This blouse was compared to the control blouse which had been cleaned by a conventional dry cleaning establishment. Also, no shrinkage or color change was observed in the control blouse, and the four stains were also effectively removed.

0101As in the prior cleaning example, it can be readily appreciated that the use ofthe liquid compositions and the processes being taught herein are very favorably comparable to that which is provided by a conventional dry cleaning apparatus, but notably the compositions and processes of the invention may be practiced by a consumer in a much shorter span of time and in the convenience and approved sanitary environment of their own dryer apparatus.
