Antiperspirant/deodorant composition

[0001] Antiperspirant and / or deodorant compositions are used to reduce perspiration in the axillary region (under the arms) and / or to combat bacteria in this area to reduce or eliminate the body odor induced by bacterial growth in this area. Antiperspirants / deodorants can exist in many forms, e.g. roll-on, gel or solid stick. Such compositions are used in the axillary region; they dry out as the volatile carriers evaporate and leave the active material. When roll-on or gel compositions dry out, they can leave a feeling of stickiness and moisture on the skin.

[0002] It would be advantageous to develop an antiperspirant / deodorant composition that reduces or eliminates the feeling of stickiness or moisture, in particular for roll-on applications where the water content is usually 50% of the composition.

[0003] JP 62-111912 discloses an antiperspirant stick.

[0004] WO 01/70 185 relates to antiperspirant compositions containing natural oils.

BRIEF SUMMARY OF THE INVENTION [0005] The present invention relates to a liquid composition according to claim 1 wherein The composition according to claim 1, wherein the liquid composition comprises: a) a structuring agent comprising at least one vegetable oil with a melting point of 26 to 38 ° C, said at least one vegetable oil comprising partially hardened soybean oil in an amount of 5% or less weight; and b) at least one active ingredient selected from active compounds for antiperspirants and active ingredients for deodorants in an amount of 0.5 to 16% by weight of the composition based on the weight of the active ingredient.

[0006] Preferred features are given in the dependent claims.

DETAILED DESCRIPTION OF THE INVENTION [0007] In the text of the document, ranges are used to shorten the description of each value in the range. As a range limit, you can select any value in the range. References to percentages throughout the text of the description are based on the weight of the active ingredient relative to the total weight of the composition, in addition to surfactants, which are included in the form provided.

[0008] The composition is fluid. The liquid composition can be made in the form of an antiperspirant and / or a roll-on deodorant. The liquid formulation may be an oil-in-water emulsion or a water-in-oil emulsion. In one embodiment, the composition is an oil-in-water emulsion. The fluid may be in any roll-on dispenser containing a ball for applying the composition to the surface of the skin.

[0009] In one embodiment, the composition does not contain glycerol (glycerol), sorbitol, ethylene glycol, propylene glycol, sunflower oil, borage seed oil, and combinations thereof. If these materials are present in sufficiently large amounts, they increase the tackiness of the composition as well as the drying time of the product. In addition, the addition of these components does not add a structure to the composition.

[0010] The composition comprises a vegetable oil with a melting point of 26 ° C to 38 ° C, which is the oil obtained from the plant or its equivalent synthetically produced. The term oil used in the document includes materials classified as liquid wax. For example, jojoba oil can be described as a liquid wax. The definition of vegetable oil also contains methyl and ethyl esters of vegetable oils. Such an oil of vegetable origin may give the composition a structure. In one embodiment, such material is present in an amount of 5% or less by weight of the composition. Concentrations significantly higher than 5% give a feeling of oily / greasy compositions and increase the drying time. In one embodiment, the amount of oil of plant origin is from about 1 to about 3% by weight of the composition. Examples of vegetable oils include, but are not limited to, soybean oil, jojoba oil, coconut oil, safflower oil, palm oil, cotton seed oil and pine seed oil. In some embodiments, vegetable oils are partially hardened varieties of these oils. A lower level of unsaturation may reduce the potential for chemical interactions

With other components of the roll-on composition, and may reduce the tendency of oil to oxidise and produce a rancid aroma that is intense and difficult to mask with other fragrances. The iodine number and the percentage of saturated fat (these values ​​are reciprocally proportional) are two ways to describe the degree of hydrogenation of vegetable oil.

[0011] The content of the vegetable oil reduces the stickiness of the active ingredient of the antiperspirant present in the aqueous phase. The addition of optional softeners in combination with an oil of vegetable origin may also give the desired effect, wherein the total amount of softening agent and vegetable oil is about 5% or less. The stickiness is determined organoleptically by a group of experts consisting of at least 10 trained assessors who define the characteristics of the sensation of the preparations on the skin. One of the properties of the product marked as part of the test, both on the forearm and under the armpits, is stickiness. The trained assessor determines the stickiness of the product based on the sensation that he leaves on his toes in certain time intervals,

[0012] The reduction of the humidity sensation can moreover be obtained by giving the formulation a certain texture and density, so that the user can feel it as a large amount of the formulation.

[0013] In one embodiment, the plant derived oil is chosen to be partially cured and has a melting point of 26 ° C (80 ° F) to 38 ° C (100 ° F). In another embodiment, the melting point is 26 ° C (80 ° F) to 35 ° C (95 ° F). To obtain a suitable melting point, the plant derived oil may be partially cured or a blend of oils uncured with partially or fully hardened oils and / or waxes.

[0014] In one embodiment, the oil of vegetable origin comprises a partially hardened soybean oil having an iodine value in the range of about 75 to about 80. The iodine number can be measured by the ASTM D5554-95 (2006) method. Such partially hydrogenated soybean oil can be obtained from Cargill; product designation S-500. This material has a typical fatty acid composition as shown in the table below. The values ​​shown are% by weight.

<td>C16: 0</td><td>10,5-11,2</td>

<td>C18: 0</td><td>6.8-7.5</td>

<td>C18: 1</td><td>61-65</td>

<td>C18: 2</td><td>16-19</td>

<td>C18: 3</td><td>0-0.2</td>

<td>saturated</td><td>17,5-19,5</td>

<td>Trance</td><td>34-39</td>

[0015] Another benefit of using a partially hardened vegetable oil, e.g. soybean oil, is that it imparts a structure in the form of increased stickiness. The viscosity, i.e. the structure of the liquid composition, is measured in mPas (centipoise) using a Brookfield viscometer at 23 ° C using a spindle 4 at 20 rpm. The viscosity of the gel composition is measured in Pa (G 'and G ") using an AR 1000 rheometer at 21 ° C in oscillation mode.

[0016] An additional benefit of using a partially hardened vegetable oil, for example soybean oil, in the present invention is the ease of imparting the fragrance composition. The reduced level of unpleasant odor created by the aging of the composition, if the formulation contains partially hardened vegetable oils, allows the fragrance substance to give a more pleasant smell and does not have to mask unpleasant odors at the same time. Partially hardened vegetable oils have a lower iodine value which corresponds to a smaller number of double bonds. A reduced number of double bonds means less potential for odor degradation.

[0017] Any surfactant that is suitable for use in antiperspirant and / or deodorant compositions may be used. The surfactant may be in any suitable amount. In one embodiment, the amount of surfactant is 2 to 12% by weight of the composition. The amount in the composition is given in relation to the material provided. In another embodiment, the amount of surfactant is about 3 to about 10% by weight. In one embodiment, the composition is a roll-on oil preparation

0 in water, the amount of surfactant is about 2 to about 5%. In one embodiment, if the composition is a water-in-oil gel composition, the amount of surfactant is about 3 to about 10%. Examples of surfactants include, but are not limited to, nonionic surfactants, silicone surfactants and combinations thereof.

Non-ionic surfactants which may be used include, but are not limited to: (a) sorbitan esters and ethoxylated sorbitan esters (e.g. sorbitan PEG-20 isostearate, sorbitan monolaurate, polysorbate-20, polysorbate-40, polysorbate-60, polysorbate) -80); (b) ethoxylates (e.g., Ceteth-20, castor oil PEG30, hardened castor oil PEG-40, hardened castor oil PEG-60, Laureth-7,

Isolaureth-6, Steareth-10, Steareth-20, Steareth-21, Steareth-100, Ceteareth-12, Oleth-5, Oleth-10); (c) ethoxylated adducts (e.g. PEG-25 stearate, glyceryl stearate and PEG-100 stearate); (d) PEG esters (e.g. PEG-8 oleate, PEG-8 laurate, PEG-8 dilaurate, PEG-12 dilaurate, PEG-80 diisostearate, PEG-40 stearate); (e) propoxylates (e.g. PPG-10 butanediol, PPG-50 oleyl ether, PPG-2-ceteareth-9,

PPG-3-deceth-3, PPG-5-ceteth-20); (f) ethoxylated modified triglycerides (e.g. PEG-20 corn glycerides, PEG-12 palm glycerides); (g) aromatic phenolic alkyl ethoxylates (e.g. dinonylphenol ethoxylate with 9 moles of EO, octylphenol ethoxylate with 20 moles of EO, octylphenol ethoxylate with 40 moles of EO); (h) block copolymers which are alkoxylated glycols containing ethoxylated and propoxylated segments (e.g. POLOXAMER ™ 182 and 234, POLOXAMER ™ 105 benzoate and MEROXAPOL ™ 174) and combinations thereof. In one embodiment, the nonionic surfactant is chosen so that it has an HLB (hydrophilic-lipophilic balance) value of 8-16 (particularly 8-12).

[0019] In one embodiment, the nonionic surfactant is selected from ethoxylated nonionic surfactants and propoxylated nonionic surfactants. Examples of such substances include, but are not limited to, Steareth 2, Steareth 20 and Steareth 21. In one embodiment of the oil-in-water composition, a combination of 2 surfactants can be used, one having an HLB value of about 2 to about 8 (e.g. Steareth 2); the other has an HLB value of about 9 to about 18 (e.g., Steareth 20 and 21).

[0020] Examples of silicone surfactants are given in U.S. Patent No. 6,485,716. Examples of silicone surfactants include silicone polyglucosides (e.g. octyldimethicone ethoxyglucoside) and silicone copolyols having an HLB (hydrophilic-lipophilic balance) value 8. The HLB value can be measured in various ways, e.g. described in conventional references, or can be found in the tables with data of this type. As intended, any type of HLB measurement method can be used.

[0021] In general, silicone copolyols include, but are not limited to, copolyols having the following formulas I and II. The materials according to formula I can be defined by the formula:

(R¹⁰) 3 SiO [(R¹¹) 2 SiO] (XSI R¹²) (R^bO (C2H4O) p (C3H6O) SR^c)ABOUT]_sSi (R¹³) 3 in which each of R¹⁰, R¹¹, R¹² and R¹³ it may be the same or different and each is selected from C1-C6 alkyl; R^b means a radical -CmH2m-; R^c means a terminal radical which may be a hydrogen atom, an alkyl group having one to six carbon atoms, an ester function, e.g. acyl, or an aryl group, e.g. phenyl; m is from two to eight; pis values ​​such that the oxyalkylene segment - (C 2 H 4 O) p - (C 3 H 6 O) s - has a molecular weight in the range from 200 to 5000; this segment preferably has fifty to one-hundred mole percent of oxyethylene units - (C 2 H 4 O) for one to fifty mole percent of oxypropylene units.

- (C3H6O) s-; x is from 8 to 400 and y is from 2 to 40. Preferably each of R¹⁰, R¹¹, R¹² and R¹³ is a methyl group; R^c is H; m is preferably three or four, wherein the R group^b most preferably - (CH 2) 3 -; and the p-values ​​are such that they provide the molecular weight of the oxyalkylene segment - (C 2 H 4 O) p (C 3 H 6 O) s - ranging from about 1,000 to 3,000. In one embodiment, the value of each of the writing should be about 18 to 28. In one embodiment, the silicone copolyol is a dimethicone copolyol.

[0022] The second siloxane polyether (copolyol) has the formula II:

(R¹⁰) 3 SiO [(R¹¹) 2 SiO] (XSI R¹²) (R^bO (C2H4O) p^c) O] ySi (R¹³) 3 wherein p is from 6 to 16; x has a value from 6 to 100; and y is 1 to 20, and the definitions of the other moieties are as given in formula I.

[0023] It should be understood that in both formulas I and II above, the siloxane-oxyalkylene copolymers may in alternative embodiments be in the form of polyethers with blocked ends in which the linking group R^b, oxyalkylene segments and the final radical R^c they occupy positions connected to the ends of the siloxane chain and are not connected to the silicon atom in the siloxane chain. In this way, one or more of the R substituents¹⁰, R¹¹, R¹² and R¹³ attached to the two terminal silicon atoms at the end of the siloxane chain may be substituted with the -R segment^b-O (C2H4O) p- (C3H6O) SR^c or the segment -R^b-O- (C 2 H₄ABOUT)_p-R^c. In some cases, it may be beneficial to enter the -R segment^b-O- (C₂H₄ABOUT)_p- (C₃H₆ABOUT)_s-R^c or R segment^b-O- (C2H4O) p^c at positions in the siloxane chain as well as at positions on one or both ends of the siloxane chain.

[0024] Specific examples of suitable dimethicone copolyols are commercially available or available from many suppliers, including Dow Corning Corporation, Midland, Mich .; General Electric Company, Waterford, NY; Witco Corp., Greenwich, Conn .; and Goldschmidt Chemical Corporation, Hopewell, Va. Examples of specific products are Dow Corning's Dow Corning 5225C, 10% dimethicone copolymer in cyclomethicone; Dow Corning 2-5185C, constituting 45-49% dimethicone copolyol in cyclomethicone, SILWET L-7622 from Witco; ABIL EM97 from Goldschmidt, representing 85% of dimethicone copolyol in D5 cyclomethicone, and various dimethicone copolyols available for sale or described in the literature.

[0025] It should further be noted that different concentrations of dimethicone copolyols can be used in cyclomethicone. Although a concentration of 10% in cyclomethicone is often commercially available, other concentrations can be obtained by evaporating cyclomethicone or adding an additional amount of cyclomethicone. In one embodiment, materials with a higher concentration may be used, for example DOW CORNING 2-5185.

In one embodiment, 0.5-5% by weight (in particular 1.0.0%) of 10% silicone copolyol, e.g. dimethicone copolyol in cyclomethicone may be used, the amount of the mixture being added selected in such a way that the level of silicone copolyol in the composition was in the range of 0.05-0.5% (in particular 0.1%) (e.g. 1% from 10% dimethicone copolyol in a cyclomethicone mixture).

[0027] The composition may additionally contain betaine. The Betaine of the present invention is not a surface-active agent. Betain according to the IUPAC nomenclature is the inner salt of 1-carboxy-N, N, N-trimethylmethanamino hydroxide, the alternative names being carboxymethyltrimethylammonium betaine or the inner salt of carboxymethyl trimethylammonium hydroxide or glycinbetaine or glycolbetaine or glycethylbetaine or trimethylglycine or trimethyl glycol. For convenience herein, the name betaine will refer to the material of formula A (C 5 H 11 NO 2; mass = 117.08 atomic mass units; molecular weight = 117.15; elemental analysis: C: 51.26; H: 9.46; N: 11.96; O: 27.32).

[0029] The use of betaine will apply to betaine of formula A or betaine hydrochloride of formula Aa. More information on betaine is given in U.S. Patent No. 6,969,510.

[0030] Betaine can be incorporated into the composition in any suitable amount. In one embodiment, the combined amount of vegetable oil and / or wax with betaine is 10% by weight of the composition or less. In another embodiment, the combined amount is about 4 to about 8% by weight. In another embodiment, the weight ratio of betaine to vegetable oil and / or wax is 3: 1 to 1: 1.

[0031] The composition may further comprise ionizable inorganic salts.

Such ionizable salts may be in the form of MaXb, in which a = 1 or 2 and b = 1 or 2,

In some embodiments, the selected salts are selected from NaCl and ZnCl2. It will be appreciated by those skilled in the art that, although in some cases the salt may be added directly to a part of the mixture during manufacture, it is desirable to add the salt as a mixture or solution of the salt in a carrier or solvent, in particular in water. Of course, different concentrations of such a salt premix can be obtained.

[0032] If the composition contains the antiperspirant active ingredient, any of the known active antiperspirants may be used in the composition. Active antiperspirants include, but are not limited to, aluminum hydroxychloride, aluminum chloride, aluminum sesquihydrochloride, aluminum-zirconium chlorychlorides, complexes or adducts of the glycol-containing active ingredients mentioned above, such as propylene glycol (e.g. "Rehydrol" II from Reheis Chemical Co.) and combinations thereof . In addition, known aluminum-zirconium salts may be used in combination with zwitterions, e.g. glycine (e.g., aluminum-zirconium tetrachlorohydres complex from Gly). In principle, any of the active ingredients of Category I antiperspirants listed in the Office's

[0035] In other embodiments, the type of suitable salt used is tetrasol or aluminum-zirconium acetate without glycine, wherein the aluminum-zirconium salt is stabilized with betaine and has a metal to chloride ratio of 0.9: 1 to 1.3: 1 (and in other embodiments, about 0.9: 1 to about 1.2: 1 or about 0.9: 1 to about 1.1: 1). In tetra-salts, the Al / Zr atomic ratio can be about 3.2: 1 to about 4.1: 1.0, and the Betaine: Zr molar ratio can be about 0.2: 1 to about 3.0: 1 ( or in other embodiments, about 0.4: 1 to about 1.5: 1). Another salt that can be used is aluminum chloride buffered with betaine, wherein the ratio of metal to chloride in the salt is 0.9: 1 to 1.3: 1 (and in other embodiments about 0.9: 1 to about 1.2: 1 or about 0.9: 1 to about 1.1: 1). In the case of octasols, the ratio of Al / Zr atoms is about 6.2: 1 to about 10.0: 1, and the betaine molar ratio: Zr is about 0.2: 1 to about 3.0: 1 (or in other embodiments about 0.4: 1 to about 1.5: 1). In one embodiment, if the salt comprises zirconium, betaine is introduced during the salt synthesis to maximize the stabilizing effect of this component (in particular with respect to zirconium compounds). Optionally, it can be added at the end to the glycine-free salt together with the additional active phase ingredients to form the betaine stabilized active substance.

[0036] Examples of commercially available tetrasols and octapels without glycine with a low M: Cl ratio include, but are not limited to, REZAL ™ AZP 955 CPG and REZAL ™ AZP 885 (both companies Reheis Chemical Company, Berkeley Heights, NJ). A more detailed description of the preparation of such salts commercially available is given, for example, in U.S. Patent Nos. 7,074,394 and 6,960,338. More examples of the preparation of such types of complex salts are given in United States Patent Application Publication No. 2004/0198998 and U.S. Patent No. 7,105,691.

[0037] In addition to the properties of betaine preventing irritation, it was further found that antiperspirant preparations maintain the fragrance stability during aging if the Al / Zr salt is used in combination with betaine.

Furthermore, the active ingredient of the antiperspirant may be the active substance of the antiperspirant stabilized with a calcium salt. Examples of active ingredients of calcium salt-stabilized antiperspirants are given in United States Patent Application Publication No. 2006/0204463.

[0039] In addition, any new component not listed in the monograph, for example, aluminum hydroxy nitrate, and its combination with zirconyl nitriles and nitriles or aluminum stannylor oxychlorides, may be used as the active ingredient of the antiperspirant. Active antiperspirants may include, but are not limited to, astringent aluminum salt, astringent zirconium salt, aluminum hydroxybromide, aluminum hydroxychloride, aluminum sesquihydrochloride, aluminum aluminum chlorohydrreks, aluminum dichlorohydreks, aluminum sesquichlorohydreks, aluminum PEG chlorohydrates, aluminum PEG dichlorohydrates , aluminum sesquichlorohydreks, aluminum chloride, aluminum sulfate, aluminum-zirconium hydroxychloride, aluminum-zirconium trihydroxychloride, aluminum-zirconium tetrahydroxychloride, aluminum-zirconium pentahydroxychloride, octahydroxychloride zirconia, aluminum-zirconium tetrachlorohydreks with propylene glycol, trichlorohydreks Gly aluminum-zirconium, tetrachlorohydreks Gly aluminum-zirconium, pentachlorohydreks Gly aluminum-zirconium, octa-chlorohydreks Gly aluminum-zirconium, buffered aluminum sulphate, potassium alum, sodium and aluminum chlorohyxacetate.

Typically, the average particle size does not exceed 150 microns.

[0042] In some embodiments, the composition may further comprise as an optional ingredient at least one an odor-preventing alpha-, beta-unsaturated ester or a mixture of such materials. In some embodiments, the level of the odor control composition resulting in a noticeable odor control benefit when provided with the antiperspirant and / or deodorant composition is about 0.05 to about 0.45% by weight relative to the total composition. The anti-odor materials constituting the alpha-, beta-unsaturated esters are introduced into the oil phase of the antiperspirant composition. An example of such anti malodour ingredients is provided in U.S. Patent No. 6,610,648 and in the United States Patent

in which n is an integer of 3-7, in particular 5-6. For example, DC-245 fluid (or DC-345 variety) from Dow Corning Corporation (Midland, Mich.) Is a type of cyclomethicone that can be used. These include tetramer (i.e. octylmethylcyclotetrasiloxane) and pentamer (i.e., decamethylcyclopentasiloxane).

Volatile linear silicones may also belong to this group of volatile silicones and constitute one or more representatives of linear polydimethylsiloxanes, for example represented by formula IV:

ch₃

H₃CSO-CH₃ ch₃ (IV) having a viscosity of 0.5-5 centistokes.

[0047] Examples of such volatile silicones include one or more representatives selected from D4, D5 and D6 cyclomethicones; and linear dimethicones with a viscosity in the range of 0.5-5 centistokes.

[0048] The composition may contain additive materials added to antiperspirant compositions and / or deodorants. Examples include, but are not limited to, monohydric alcohols, perfumes and preservatives.

[0049] If water is present, for example in a roll-on liquid composition, the amount of water in the composition is an amount to make up the composition up to 100% by weight after all materials have been added to the composition, including any optional materials. In some embodiments, the amount of water is at least about 20%, 30%, 40%, 50%, 60%, 70%, 80% or 85% by weight of the composition.

[0050] The total solids content of the composition is the amount of non-volatile materials in the composition. The solids percentage is measured using a CEM Smart System moisture / solids analyzer that dries the samples using microwave energy. In one embodiment, the total solids content is less than about 25%. In another embodiment, the total solids content is less than about 20%.

[0051] The invention is discussed in more detail below with the aid of the following examples.

The examples are illustrative only and in no way limit the scope of the invention described and claimed.

[0052] Roll-on compositions may be prepared using the formulations and procedures set out below.

1. Water phase: Mixing of deionized water and surfactants:

a. Heating of part 1 of water to 84-85 ° C.

b. Melting and adding surfactant (i.e., Steareth 20) to heated water. Mixing to completely dissolve solid substances.

c. Maintaining a temperature of 80-84 ° C.

2. Oil phase: Mixing softeners and surfactant.

a. Weighing PPG 15.

b. Melting of surfactants in the oil phase (i.e., Steareth 2) and addition to PPG-15.

c. Addition of unmelted softening agents and oils of vegetable origin.

d. Adding BHT

e. Heating up to 50 ° C with mixing of all ingredients.

f. Continuation of mixing, bringing the temperature to 64-66 ° C.

3. Addition of the oil phase to the aqueous phase using a Rustin disk with mixing at high speed (360 rpm). Addition speed: about 20 g / min. Turning off the heating. Reducing the mixing speed to 320 rpm.

3. When the temperature drops to 68-70 ° C, adding EDTA solution, continue mixing at 320 rpm.

4. Adding the active phase.

a. Increase the mixing speed to 350 rpm and slowly add part 2 of the water - (cooling).

b. Addition of active antiperspirant ingredient, continuation of mixing at 350 rpm.

c. Allow to cool to 44-46 ° C.

d. Decrease the stirring speed to 320 rpm. Addition of Quaternium 15 solution.

e. When the temperature drops to 35 ° C or less, slowly adding perfume with the dropper, continue stirring at 320 rpm.

f. Continue mixing for 10-15 minutes after completing the perfume addition.

[0054] Optionally, a homogenisation step may be provided between steps 3 and 4. Homogenization using a Silverson homogenizer for 5 minutes after completing the oil phase addition.

[0055] Optionally, the antiperspirant active solution may also be added together with water and surface active agents in the aqueous phase.

[0056] The viscosity is measured in mPas (centipoises) using a Brookfield viscometer at 23 ° C using a spindle 4 at 20 rpm.

[0057] All amounts shown in the examples below represent weight percentages based on the weight of the active substance in the material, in addition to surfactants, which are included in the form provided. The amount of tetrasodium EDTA salt has a water load. EDTA is 80%, so the weight of the active ingredient is 0.2% by weight.

[0061] The following composition is an example of a water-in-oil gel composition that can be made by the following procedure. The sample size is about 500 grams. The silicone copolyol (PEG / PPG-18/18 dimethicone), silicones, soybean oil and perfume were weighed and combined in a beaker. The mixture was mixed at 400-600 rpm using a Lightnin model LI003 mixer. After obtaining the visually homogeneous mixture to the oil phase, the active phase containing the active ingredient of the antiperspirant in water and the remaining ingredients (tripropylene glycol, ethanol and additional water) were added. The whole mixture was stirred for 15 minutes. The mixture was then homogenized for 1-3 minutes at 40-60 read on a Powerstat regulated transformer (Superior Electric Co., Bristol, CT) using a Greerco Corp. homogenizer. (Hudson, NH). The Brookfield viscometer with spindle E at room temperature (about 23 ° C) was used to determine the viscosity of water-in-oil formulations. Spindle E speed is 2.5 rpm.
