Hair cosmetic composition.

DESCRIPTION

This invention relates to hair cosmetic compositions and more specifically to compositions containing a fine particulate polymer, insoluble in water, with excellent styling and retention behavior and also communicating a pleasant touch to the hair.

Hair styling is one of the most important factors in beauty care and various types of treatments have been used to perform the hairstyle. For example, hair can be rolled and dried around curlers or treated with a hair dryer and a brush to do the hairstyle. In these hair treatments, it is usual practice to use hair cosmetics such as fixing lotions, brushing agent, hair lacquers and the like in order to facilitate the realization or preservation of the hair done. Therefore, various polymers that are soluble in water or in organic solvents such as alcohols are incorporated into the cosmetic hair compositions. Examples of these polymers are polyvinylpyrrolidone, vinylpyrrolidone / vinyl acetate copolymers, vinylpyrrolidone / vinyl acetate / aminoethyl acrylate copolymers, methylvinyl ether / maleic anhydride copolymers, vinyl acetate / acrylic acid copolymer copolymers, methacrylic and esters of acrylic or methacrylic acid. Hairstyles are made or maintained by spreading the polymers or applying them with a spray on the hair.

However, conventional hair cosmetic compositions have the disadvantage that it is necessary to deposit a large amount of polymeric materials on the hair to maintain the hairstyle. In addition, as the polymeric materials deposited on the hair have a surface tension greater than the critical surface tension of the hair, they are deposited in small agglomerates isolated on the hair, which leads to a rigid touch of the hair and an insufficient styling facility.

After washing the hair with a shampoo, rinsing creams, treatment agents, etc. have been used to eliminate unfavorable dryness of the hair, to give it a soft touch and to obtain an easy hairstyle. However, as they contain cationic surfactants or oily ingredients, although they can increase the smoothness and ease of styling of the hair, they have the disadvantage that the hair becomes sticky and it is difficult to perform or preserve the hairstyle, so it is necessary to introduce Improvements in these compositions.

Envistadelasituacióon described, the present inventors have made a serious study to obtain a hair cosmetic composition with excellent properties of realization or preservation of the hairstyle and, as a result of this study, they have completed this invention based on the finding that a hair cosmetic composition can be obtained , capable of communicating to the hair an excellent effect of realization or preservation of the hairstyle without prejudice to the touch of the hair and with properties that favor the hairstyle, mixing a particulate polymer with cosmetic hair compositions used as shampoos, rinsing creams, treatments, hairspray , fixing lotions and the like.

Accordingly, this invention provides capillary cosmetic compositions containing from 0.01 to 10% by weight of a particulate polymer, with a weight average diameter of 0.005 to 0.2 μm, said particulate polymer having a particle size distribution such that particles of 0.005 to 0.2 μm in diameter constitute mine of 95% of the weight of the polymer and with a glass transition temperature, Tv, greater than 300 K. It is preferable that the particulate polymer with the particle size indicated above be used in the form of a polymeric latex comprising that particulate polymer.

The polymeric latex comprising the particulate polymer cannot be prepared by a conventional emulsion polymerization process where the polymerization is carried out in the presence of an emulsion of polymerizable monomer droplets in the polymerization system.

In accordance with this invention, the polymeric latex is prepared by polymerization of a polymerizable water-soluble microemulsion monoimmer in solution or microemulsion. The microemulsion can be prepared using a non-ioin surfactant and selecting a temperature suitably close to the phase transition temperature or by combining the anionic surfactant with an appropriate auxiliary surfactant such as a higher alcohol or a non-ionic surfactant. In addition, the solubilized state can be obtained using a large amount of surface active agent with respect to the polymerizable monomer.

Among these procedures, the most preferred corn is the one that performs the microemulsion polymerization using a non-ionic surfactant, a polymerization temperature close to the phase transition temperature and with an interfacial tension between the monomer and the water not exceeding 1 dyne / cm and preferably not more than 0.5 dynes / cm.

The process for preparing the polymeric latex used in this invention will be explained together with the polymerizable monoimers that can be used for its preparation.

(1) Polymeric latex polymerized by addition:

The additive polymerized latex can be obtained by polymerization of a polymerizable monomer while maintaining a microemulsion of an aqueous solution of a surface active agent with an interfacial tension between the monomer and the water less than 1 dyne / cm, where the polymerizable monomer is solubilized within of the micelles formed by the surfactant.

As the polymerizable monomer, any of the known monoimers used in emulsion polymerization can be used, including monomers with ethylenic unsaturation such as ethylene, propylene, isobutene and butene-1; aromatic vinyl monoimers such as styrene, α-methyl styrene, vinyl toluene, halogenated styrene and vinylbenzene; acrylic esters of 1 to 20 carbon atoms in the alkyl group such as ethyl acrylate, butyl acrylate and 2-ethylhexyl acrylate; methacrylates of 1 to 20 atoms of

000 892 carbon such as methyl methacrylate, butyl methacrylate and lauryl methacrylate; vinyl esters such as vinyl acetate and vinyl propionate; vinyl ethers of 1 to 20 carbon atoms such as ethyl vinyl ether and butyl vinyl ether; vinyl ketones of 1 to 20 carbon atoms such as methyl vinyl ketone and ethyl vinyl ketone; cyanovinyl monomers such as acrylonitrile and methacrylonitrile; halogenated vinyl and halogenated vinylidenes such as vinyl chloride, vinyl bromide, vinylidene chloride and vinylidene bromide; and conjugated aliphatic dienes such as 1,3-butadiene and 2-methyl-1,3butadiene. These monoimers can be used by themselves or as mixtures of two or mine of them. In addition, any of the aforementioned monoimers can be subjected to copolymerization with maleic anhydride, a water-soluble monoimer, styrenesulfoinic acid (or its salts), vinylnaphthalensulfoinic acid (or its salts) or acrylic acid (or its salts).

The most preferred process for producing the additive polymerized latex is performed by adding a surfactant to a reaction vessel charged with water to prepare an aqueous solution, adding the polymerizable monomers and, if necessary, an aqueous solution of a polymerization initiator. by radicals, while stirring and heating at a temperature close to which the micelles of the surfactant produce phase transition, while this state is maintained where the interfacial tension between the monoimer and the water is not greater than 1 dyne / cm, and preferably is from 0 to 0.5 dynes / cm, thus initiating polymerization and then gradually adding a polymerizable monoimer such that The interfacial tension between the aqueous solution of the surfactant and the monomer phase does not exceed the aforementioned range.

The radical polymerization initiator suitably used herein may be, for example, a persulfate such as potaisic persulfate, sodium persulfate and amoinic persulfate; azo compounds such as mineral acid salts of 2.2^/-azobis (2-amidinopropane), azobiscianobuaríeric acid and its alkali or ammonium metal salts and redox initiators such as tartairic acid-hydrogen peroxide, Rongalitperoxide and ascoirbic acid-perioxide. Among them, a mineral acid salt of 2.2 is preferably used^/-azobis (2-amidinopropane) when a cationic surfactant of the polymerization system and a persulfate are used in other polymerization systems. The amount of initiator of the radical polymerization is 0.1 to 5 parts by weight and preferably 0.1 to 3 parts by weight, calculated on 100 parts by weight of the monoimer constituting the polymer.

The reaction temperature is the maximum temperature within the solubilizing region near the phase transition temperature and a temperature between 50 and 90 ° C is preferred. Although the time required for polymerization varies with the type, composition and concentration of the monomer or with the concentration of the radical polymerization initiator, with the polymerization temperature, etc., preferably a time of 5 to 50 hours is used. .

In this way a polymeric latex is obtained that contains a particulate polymer with an average particle size of 0.005 to 0.2 µm and where 95% by weight or more of the particles are within this range of sizes.

(2) Polycondensation latex:

The polycondensation latex is obtained by polymerizing a polycondensible monomer while maintaining a microemulsion of an aqueous solution of a surfactant, which has an interfacial tension between the monoimer and water not exceeding 1 dyne / cm and where the polycondensible monomer is solubilized within of the micelles formed by the surfactant.

As a polycondensible monomer, any of the known monoimers used in the polycondensation at the interface or in the polycondensation at low temperature can be used. Among them, monomers capable of polyamide or polystyrene forms are preferred. For example, the acid component for preparing the polyamide includes alkylenedicarboxylic acids whose hydrocarbon groups contain from 1 to 24 carbon atoms, phthalic acids such as dimer acid, terephthalic acid and isophthalic acid, the corresponding acid chlorides or carboxylic acidic carboxylic acid anhydrides and of cycloaliphatic polybasic carboxylic acids such as cyclohexyldicarboxylic acid and, in addition, thioesters of dicarboxylic acids. In addition, the amino component can be, for example, an aliphatic polyamine whose hydrocarbon groups contain from 1 to 24 carbon atoms, eg alkylenediamines and alkylenetriamines, aromatic polyamides such as phenylenediamine and polyamines with a heterocyclic ring such as 4.4^/-diaminophenyl ether.

In addition, the alcohol component in the case of preparation of the polyether can be an alkylene diol comprising hydrocarbon radicals of 1 to 24 carbon atoms, ethylene glycol condensates such as bis-e-hydroxyethyl terephthalate, aromatic polyhydric alcohols such as hydroquinone and bisphenol A , and polyhydric alcohols as glycerin derivatives. As an acid component, we can mention the various compounds described above.

The monomers are not limited only to those mentioned above and two or more of the monoimers can be used in mixture.

To perform the polycondensation reaction, a surface active agent is added to a reactor charged with water to solubilize the component by stirring. Then an aqueous solution of diamine or alcohol is added or, alternatively, solutions prepared by dissolving both components independently in orgaine solvents are then solubilized in the respective aqueous solutions of the surfactant and then mixed. The solid monomers are preferably dissolved in an organic solvent and solubilized together with the solvent in the form of micelles to effect polycondensation. In this case, any of the water insoluble solvents can be used and preferably benzene, toluene, xylene or the like are used. The reaction temperature is preferably a temperature within the solubilization region near the

000 892 phase transition temperature and in general is between -10 and | 50 C. In addition, although the reaction time varies with the type, composition and concentration of the monoomer or with the temperature, a time of 2 is usually preferred 60 minutes

In this way a polymeric laxtex can be obtained containing a particulate polymer with an average particle diameter of 0.005 to 0.2 μη, where 95% or more of the particles have a diameter within these lobes.

(3) Polyaddition polymerized latex:

The polyamoric polyether latex of the polyaddition polyether is obtained by polymerizing a polycondensation monoomer, in a state where the polycondensation susceptible monomer was solubilized in flat micelles formed with the surfactant, using an aqueous solution of a surfactant that produces an interfacial tension between the monoomer and water not exceeding 0.5 dynes / cm and maintaining a state of microemulsion. Although all known monomers usable in a normal polyaddition reaction can be used as polyamide-susceptible monoomers, polyurethane-forming monoomers, polyurea resins and epoxy resins are preferred.

The alcoholic component for preparing the polyurethane includes the compounds that contain at least two hydroxy groups in a molecule, specifically ethylene glycol, propylene glycol, butylene glycol, hexanodiol, neopentyl glycol, polyethylene glycol, polypropylene glycol, polyoxytetramethylene glycol or polyether terminal glycol two glycol terminal groups . On the other hand, the isocyanate component includes the compounds containing at least two isocyanate groups per molecule, specifically tolylenediisocyanate, xylethylene diisocyanate, hexamethyl endiisocyanate, 4,4'-diphenylmethanediisocyanate, triphenylmethanetriocyanate polyethanesium trimethyl polyethane, trimethylthioethane, polyethanesidethioethane, polyethylenesthioethane, trimethylthioethane, polyethanethioethane, trimethyl and polyethaneside groups Isocyanate terminals.

The aforementioned compounds can be used as an isocyanate component for the production of polyureas and the amine compounds include the compounds containing at least two amino groups per molecule, specifically hexamethylenediamine, dodecyldiamine, phenylenediamine, diaminodiphenoyl ether and piperazine.

The epoxide component for the preparation of the epoxy resin includes at least two epoxy groups containing compounds in a molecule, specifically the diglycidyl ether of bisphenol A, glycidyl oester of the dimeric acid and compounds prepared by olefin oxidation. In addition, the amine compounds described above can be used as the amine component. Likewise, all known hardeners can be used, for example tertiary amines, boron-amines and imidazole trifluoride complexes, as well as amines, polyamines, carboxylic anhydrides, polysulfides, dicyandiamides and diisocyanates with functional groups capable of reacting polyaddition with epoxy groups .

The polyaddition reaction was carried out as follows. To prepare a polyurethane or polyurea, a surfactant is added to a reactor charged with water, thereby solubilizing the isocyanate ingredient under stirring. An aqueous solution of diol or diamine is then added or, alternatively, solutions of both ingredients dissolved separately in an organic solvent are solubilized in the aqueous solutions and then mixed. To prepare the epoxy resin, a solution of a prepolymer or a combination of epoxy-terminal compound and various hardeners dissolved in a solvent is added dropwise to a hot aqueous solution of the surfactant.

When the monoomer is solid or a very viscous liquid, it is preferable to first dissolve the monoomer in an orgaonic solvent before carrying out the polyaddition reaction in micelles. Any of the inert solvents insoluble in water and not reactive with the ingredients used can be used as an orgaonic solvent, with benzene, toluene, xylene, etc. being especially preferred as solvents. The reaction temperature is selected within a solubilizing region near the phase transition temperature and is usually preferably from 20 to 70 ° C. In addition, although the reaction time varies with the type, composition and concentration of the monomer or with temperature, etc., it is preferable to use a time of 1 to 50 hours.

The phenolic resin that is a polycondensate can be prepared in the same way used for the epoxy resin described above. It can be prepared using a phenolic derivative such as phenol or cresol and formaldehyde. In addition, a resole resin or a novolac resin that is hardened by an acid or a polyamine can be used.

The asóóóóó obtained obtained contains a polóimero particulate with an average size of particle of 0,005 to 0,2 μm and with 95% in weight or more of the particles with a size within the limits mentioned. The average particle size of the polymer used in this invention is 0.005 to 0.2 μm and preferably 0.01 to 0.1 μη, converted to a weight value. In addition, 95% by weight of the polymer particles have a particle size between 0.005 and 0.2 μη. When the polymer is incorporated into hair cosmetic compositions, if the particle size is too large or too small, it is not deposited well on the hair and no substantial effect of styling formation or preservation can be observed. Therefore, the latex used as an opacifying agent for cream shampoos or the like cannot produce the effect of this invention because their average particle size is greater than 0.2 μm and they have a wider distribution of sizes.

The polymer used in this invention has a glass transition temperature (Tv) greater than 300^°K. If the glass transition temperature is lower than the mentioned value, the latex exerts little formative / conservative effect of the hairstyle if it is deposited on the hair. Polymers with a glass transition temperature (Tg) greater than 300^°K include polymers of vinyl monomers such as polystyrene, polyvinyl acetate, polydivinylbenzene, poly (methyl methacrylate), etc .; polyamides such as 6,12-nylon; po4

000 892 liurethanes such as polypropylene glycol polyaddition polymer (average molecular weight 1,000) and xylenediisocyanate and epoxy resins such as bisphenol A and diglycidyl ether polyaddition polymer. Other monomers can be added to the 5 vinyl monomers as long as they do not lower the glass transition temperature (Tv) below 300 ^ K.

Among the polymers, the most preferred are polystyrenes and copolymers of styrene and a mo- ₁₀Vinyl number other than styrene having a glass transition temperature (Tg) greater than 300 ^ K.

The hair cosmetic compositions according to this invention are prepared by mixing ₁₅directly the polymer obtained as described above with a substrate material of the hair cosmetic compositions or by mixing with the substrate a liquid suspension of the polymer previously concentrated to the concentration of ₂₀seada When aqueous capillary cosmetic compositions are prepared, it is preferable to add the polymer to the water before mixing with the other ingredients, such as a thickener. The polymer is preferably mixed with the compositions₂₅hair cosmetics in a proportion of 0.01 to 10% by weight and preferably 0.05 to 5% by weight, calculated as waste after removing the water.

In addition, to the hair cosmetic composition ₃₀According to this invention, a long-chain quaternary alkylamine salt and oils and fats can be incorporated to give the hair a more favorable touch. The long chain quaternary alkylamine salt may include the salts₃₅Long chain quaternary alkylamoinics represented by the following general formula (I):

Among the long chain quaternary alkylamoinic salts represented by the above formula (I), those containing branched long chain alkyl groups can be synthesized from a branched higher fatty acid or a branched higher alcohol. These starting compounds can be natural or synthetic products. Natural raw materials may be fatty acids of lanolin such as isoacid and anti-isoacid and terpene alcohols such as farnesol. Synthetic raw materials may be oxoalcohol prepared by the Oxo process or Guerbet alcohol or a 2-alkyl alkanol obtained by Guerbet condensation or alcohol condensation from an alcohol or aldehyde. For example, in the case of oxoalcohol, the degree of branching of the resulting higher alcohol is small when starting from an α-olefin and this degree of branching increases in the case of an internal olefin and reaches 100% in the case of a branched olefin

Among the long chain quaternary alkylamine salts of the branched type, those containing a 2-alkylalkyl group represented by the following general formula (II) are preferred as branched alkyl group:

CH3 ^|

R-CH-CH2 (II) where R represents a linear alkyl group of 5 to 13 carbon atoms and preferred examples of these groups are 2-methylctyl, 2-methyldecyl,

2-methylundecyl, 2-methyldodecyl, 2-methyltridecyl,

2-methyltetradecyl, 2-methylheptadecyl, etc. These 2-methylalkyl groups are usually obtained from oxoalcohol which is generally obtained as a mixture of straight chain alcohols.

Long-chain quaternary alkylammonium salts of the branched type containing these branched alkyl groups include alkyltrimethylammonium chlorides, dialkyl dimethyl ammonium chlorides, alkyl dimethylbenzyl ammonium chlorides, alkyltrimethylammonium bromides, alkyltrimethylammonium methyl sulfates and dialkylmethyl hydroxyl chlorides. Among them, those containing a methyl alkyl group represented by the formula (II), of which branched long-chain quaternary monoalkylamine salts such as 2-methyldecyltrimethylammonium chloride, 2-methyldodecyltrimethylammonium chloride and 2-chloride are especially preferred -methyltetradecyltrimethylammonium; branched long chain quaternary dialkylamoin salts where one of the branched long chain alkyl groups is, such as 2-methyldecyldecyldimethylammonium chloride, 2-methyldodecyltridecyldimethylammonium chloride, 2-methyltetradecylpentadecyldimethylammonium chloride; and branched long chain dialkylamoinic salts where the two branched stain long chain alkyl groups, such as di (2-methyldecyl) dimethylammonium chloride, di (2-methyldodecyl) dimethylammonium chloride and di (2methyltetradecyl) dimethylammonium chloride.

Examples of linear long chain alkyl groups can be decyl, undecyl, dodecyl, tridecyl, tetradecyl, pentadecyl, hexadecyl, octadecyl, eicosanyl and the like.

Oils and fats in general can be used herein and include liquid paraffins, glycerides, higher alcohols, lanolin derivatives, esters and higher fatty acids. The glycerides used are monoglycerides of fatty acids derived from linear or branched chains, saturated or unsaturated, from 12 to 24 carbon atoms. Among the oils and fats, higher alcohols with linear or branched alkyl or alkenyl groups of 12 to 26 carbon atoms are especially preferred and cetyl alcohol, stearyl alcohol, al5 are specific examples.

When it is incorporated into a hair cosmetic composition of this invention from 0.01 to 10% by weight of casein or a casein derivative, the facilitating and conservative effect of the hairstyle is also increased without prejudice to the touch of the hair. Casein derivatives include casein metal salts, casein hydrolysates and the like. As the casein metal salt, a sodium salt of a hydrolyzate with an average molecular weight of 1,000 to 50,000 and the casein hydrolyzate, respectively, are preferred.

The hair cosmetic compositions that can produce excellent effects due to the incorporation of the polymer and, if necessary, of a long-chain quaternary alkylamine salt and oils and fats in this invention, were not subject to any particular restriction and may be, for example , shampoos, hair rinse creams, hair conditioners, hair treatments, hair styling creams with hair dryers, hair fixing agents, hair liquids, hair aminics, brushing agents, lacquers and hair dyes. In addition, there is no specific restriction as to the formulations of the hair cosmetic compositions that can be mixed with the polymer and these can be, for example, aqueous solutions, ethanolic solutions, emulsions, suspensions, gels, solids, aerosols, powders and the like. .

The hair cosmetic compositions according to this invention exert excellent effects of facilitation and preservation of the hairstyle, good depoisitic properties, excellent touch and can communicate to the hair an excellent capacity for formation and preservation of the hairstyle and a pleasant touch. In addition, they lack drawbacks such as easy separation and difficulty of combing when they are incorporated into a cosmetic hair composition in comparison with inorganic powders such as talc, mica and titanium readily available as fine powder.
