Description

BACKGROUND OF THE INVENTION

The present invention concerns a cosmetic composition for hair care. Especially the invention concerns a cosmetic composition with hair conditioning action, which imparts a silky smooth feeling and especially softness to the hair and preferably is formed as a rinse-off composition. This cosmetic composition includes a combination of a silicon compound, a multivalent alcohol and a cationic surfactant.

Conventional hair conditioning preparations are formulated as rinse-off care or leave-on compositions generally based on aqueous emulsions. Cation-active substances, for example cationic surfactants, hydrophobic substances, such as fatty alcohols, and other oily components, emulsifiers and additional specific effective and perfume substances are essential ingredients. The most important ingredients are cationic surfactants, fatty alcohols, silicon compounds and emulsifiers. The primary objects of hair conditioning agents are the improvement of manageability, combability, the luster and feel of the treated hair. The treated hair often feels heavy and loaded, which is not always desirable. These often observed undesirable effects are very strongly dependent on the hair type. Particularly ethnic hair types are not satisfactorily treated with commercial hair conditioning agents.

Products, with which good results may be obtained concerning silky and smooth feel, manageability and softness of dry hair, especially with difficult types of hair, are desired.

Difficult or problematic hair types typically are found on Asiatic people. This full, smooth and heavy hair very easily tends to require excessive care and is difficult to set in a hair style. There are two distinctive dry types, fashion-dependent for Asiatic people: the Sara-Sara type (“flexible-dry” or “supple-dry”), for airy-light fluffy or loose hairstyles, and the Shittori type (“flexible-moist” or “supple-moist”), which is typically for optically more placid or quiet, smoother hairstyles.

Conditioning hair care agents are known in various forms. They are based on polymers with thickening action, such as cellulose derivatives (trademarks: NATROSOL®, METHOCEL®), high molecular weight Chitosan derivatives (trademark: KYTAMER® PC), complex polysaccharides (tradenames: Karaya gum, Tragacanth gum, JAQUAR® types, KELTROL® types), acrylic acid polymerizates or silicones. For example, WO 01/28506 (Wella AG) describes a water-in-silicone oil hair conditioning composition, which contains a certain silicone surfactant, a hydrophobic non-surfactant silicone compound and a hydrophobic non-surfactant polyhydric alcohol.

Such hair conditioning compositions have however the great disadvantage that their care action is so weak, especially with the above-mentioned problematic hair, that it is far from that of a classical hair care composition based on a mixture of fatty alcohol, quaternary surfactants and silicones. Especially the distributability of this product on full hair and the rinsability are poorer in comparison to a typical liquid crystal gel. Furthermore the dry hair feels clearly loaded or heavy.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide a composition, which fulfills the typical requirements regarding hair conditioning and distributability and also for typical Asiatic hair regarding silky and smooth feel, manageability and softness and with which good action may be obtained in the distinctive Shittori Effect (generally defined as “flexible-moist”).

It has now been found that this object is attained in an outstanding manner by a hair conditioning agent of the following composition.

Thus the subject matter of the invention is a cosmetic composition with conditioning action for hair containing

• • a) from 0.01 to 20.0 percent by weight of at least one siloxane polymer of formula (I): wherein R1, R2 and R3 are each, independently of each other, a linear or branched C₁- to C₆-alkyl group, phenyl group or a linear or branched phenyl-(C₁— to C₆)-alkyl group, and wherein x and y represent whole numbers, x≧4 and y≧1, and y has a maximum value of 100,000 and x has a maximum value of 100,002; and
  • b) from 0.1 to 20.0 percent by weight of at least one polyhydric alcohol.

Preferably preferred embodiments of the cosmetic composition contain from 0.1 to 20.0 percent by weight of at least one fatty alcohol as additional component (c) and/or from 0.1 to 10.0 percent by weight of at least cationic surfactant as additional component (d).

The agent fulfills the requirements for a hair conditioning agent regarding conditioning action. The agent can be distributed satisfactorily on the hair. The hair is both noticeably smoother and softer after treatment both in a moist and also in a dry state. The hair is combed better and set in a hairstyle better, disentangled and lustrous.

The cosmetic composition according to the invention can thus be used preferably for improvements of the feel, luster, flexibility, manageability, combability, softness and weight (Shittori) of hair.

The siloxane polymer of component (a) is present in the agent according to the invention in an amount of 0.01 to 20.0, preferably of 0.1 to 10.0, especially preferably from 0.1 to 5.0, and most preferably from 0.5 to 3.0, percent by weight (wt. %).

Preferred siloxane polymers are those, in which R1, R2 and R3 each represent, independently of each other, a methyl, propyl, butyl, phenyl, phenyl-propyl or phenylisopropyl group, x and y represent whole numbers, x≧4 and y≧1, and y has a maximum value of 100,000 and x has a maximum value of 100,002.

Preferred siloxane polymers, which are especially preferred, include those of the following formula (I): wherein Z represents a branched or unbranched C₁- to C₆-alkylene group, R1 and R2 each represent a C₁- to C₆-alkyl group, and x and y are whole numbers, x≧4 and y≧1, and y has a maximum value of 100,000 and x has a maximum value of 100,002.

Siloxane polymers of the following formula (III) are especially preferred: wherein x and y are whole numbers, x≧4 and y≧1 and y has a maximum value of 100,000 and x has a maximum value of 100,002.

An especially preferred siloxane polymer of this type has the INCI name phenylpropyldimethylsiloxysilicate and is commercially obtainable from GE Bayer silicones under the trademark SILSHINE® 151 and/or under the trademark BAYSILONE® CF-1301 (GE Silicones) according to the International Cosmetic Ingredient Dictionary and Handbook, Tenth Edition, 2004, Volume 2, p. 1370.

However a siloxane polymer according to formula (III) with the above-described definition, which is characterized by an index of refraction n²⁰_D between 1.49 and 1.52, preferably 1.51, is especially preferred. This sort of siloxane polymer has a viscosity between 280 and 600 mPas, measured at 25° C. with the Haake rotary viscometer Type VT 550 (measurement system comprising a measurement beaker or container MV-DIN and a rotating body according to DIN 53019/ISO 3219) with a shear rate of 12.9 per second.

Also at least one other silicone compound with hair conditioning properties can be added to the combination according to the invention. In principle all silicone compounds are suitable, which are insoluble in the aqueous phase and are low molecular weight, easy-to-volatilize silicones or high molecular weight, difficult-to-volatilize silicones. Non-volatile silicones are silicones with no or only slight vapor pressure under normal conditions (1 atmosphere, 25° C.). These silicones remain in the hair, after they are applied. Volatile silicones in contrast evaporate after application to the hair under normal conditions in a time interval of typically about two hours. The high molecular weight silicones can be silicone resins or silicone gum, which are soluble in a low molecular weight liquid silicone. The low molecular weight silicone oils have a viscosity of preferably 100 to 1000 mPas, and the high molecular weight silicone oils have a viscosity of above 1,000 to 2,000,000 mPas, measured at 25° C. with a Haake rotary viscometer Type VT 550 (measurement system as already described above) and a shear rate of 12.9 per second.

Hydrophobic silicones generally can include cyclic polydimethylsiloxane (INCI name: cyclomethicone), such as octamethyl cyclotetrasiloxane and decamethylcyclopentasiloxane; linear polydimethylsiloxane (INCI-name: dimethicone), polydiethylsiloxane, additional phenyl substituted siloxanes, such as those with the INCI name phenyltrimethicone, polymethylphenylsiloxane, phenylpropyltrimethicone, phenylpropyltrimethicone/diphenylmethicone, diphenyldimethicone, diphenylisopropyldimethicone, triphenyltrimethicone, hydroxysubstituted siloxane (INCI name: dimethiconol) or their mixtures.

Ingredient (b) comprises a branched or unbranched polyhydric aliphatic alcohol, preferably with at least two hydroxyl groups, which includes also sugar alcohol, preferably with 2 to 6 carbon atoms. The polyhydric aliphatic alcohols, for example, can be ethylene glycol, 1,3-butylene glycol, 1,2-propylene glycol, propan-1,3-diol, butan-1,3-diol, caprylyl glycol, glycerol or sorbitol. The polyhydric or multivalent alcohol is used in the composition according to the invention preferably in an amount of 0.1 to 50 percent by weight, especially from 1.0 to 25% by weight, particularly of 2.0 to 10.0% by weight, for example 5% by weight.

Besides the polyhydric alcohol the composition according to the invention can also contain lower monohydric or monovalent alcohols with from 1 to 4 carbon atoms, for example ethanol or isopropanol.

Preferably the composition according to the invention can contain at least one fatty alcohol as the additional ingredient (c).

The fatty alcohols that can be used in the composition according to the invention include all those fatty alcohols that can be used for cosmetic purposes. In the sense of the present invention the “fatty alcohols” are those of the formula (IV): R²OH  (IV), wherein R² represents an aliphatic, linear or branched C₁₀- to C₂₂-alkyl group. Preferred fatty alcohols include those, in which R² represents an aliphatic linear or branched C₁₀- to C₂₂-alkyl group. For example, capryl alcohol, 2-ethylhexyl alcohol, lauryl alcohol, myristyl alcohol, oleyl alcohol, cetyl alcohol, stearyl alcohol, isostearyl alcohol, behenyl alcohol, linoleyl alcohol, linolenyl alcohol, ricinoleyl alcohol, cetearyl alcohol and mixtures thereof are suitable as the fatty alcohol. The fatty alcohol is present in the composition according to the invention in an amount of from 0.1 to 20.0% by weight, preferably 0.5 to 10.0% by weight, especially preferably from 1.0 to 8.0% by weight, for example 4.0% by weight.

Cationic surfactants preferred as the additional ingredient (d) in the composition according to the invention include those which contain quaternary ammonium groups. The additional ingredient (d) can be a cationic surfactant or an amphoteric betainic surfactant. However cationic surfactants are preferred. Suitable cationic surfactants contain amino groups or quaternarized hydrophilic ammonium groups, which have a positive charge in solution and which can be represented by the following general formula (V): N⁺R¹R²R³R⁴X⁽⁻⁾  (V), wherein each of R¹ to R⁴, independently of each other, denote an aliphatic group, an aromatic group, an alkoxy group, a polyoxyalkylene group, an alkylamido group, a hydroxyalkyl group, an aryl group or an alkaryl group, each with from 1 to 22 carbon atoms. X⁽⁻⁾ is a cosmetically compatible anion. The anion can be a halogen, acetate, phosphate, nitrate or alkyl sulfate anion. However chloride is preferred.

In order to guarantee surfactant properties each of the R¹ to R⁴ groups has at least eight carbon atoms. The aliphatic groups can also contain cross-linkages or other groups, for example amino groups, besides the carbon atoms and the hydrogen atoms. For example, suitable cationic surfactants include ammonium halides, especially the chlorides or bromides, such as alkyldimethylbenzyl-ammonium salts, alkyltrimethylammonium salts, dialkyldimethylammonium chlorides and trialkylmethylammonium chlorides or bromides, for example cetyltrimethylammonium chloride or bromide, stearyltrimethylammonium chloride or bromide, distearyltrimethylammonium chloride or bromide, lauryldimethyl-benzylammonium chloride or bromide, tetradecyltrimethylammonium chloride or bromide, alkyldimethylhydroxyethylammonium chlorides or bromides, alkyl-trimethylammonium chlorides or bromides, dialkyldimethylammonium chlorides or bromides, alkylpyridinium salt, especially lauryl or cetyl pyridinium chloride, alkylamidoethyltrimethylammonium ether sulfate and compounds with cationic character, such as amine oxides, especially alkylmethylamine oxides or alkylaminoethyldimethylamine oxides. Cetyltrimethylammonium chloride or cetrimonium chloride are especially preferred, which is marketed, for example, in the form of a 26% percent aqueous solution under the trademark DEHYQUART® A from Cognis and under the trademark GENAMIN® CTAC of Clariant and in the form of a 50 percent solution in isopropanol under the trademark ARQUAD® 16-50 of Akzo Nobel.

The cationic surfactant is present in the composition according to the invention in an amount of 0.1 to 10.0 wt. %, preferably 0.5 to 8.0 wt. % and especially preferably 1.0 to 5.0 wt. %, for example 2.0 wt. %.

The composition according to the invention can be in the form of a shampoo, a cream, a lotion or a fluid gel or pourable gel, pump foam or aerosol foam.

If the composition is in a low viscosity form, it can also be sprayed in order to achieve an especially good distributability on the hair. The hair treatment composition according to the invention is then used in combination with a suitable mechanical spraying device. The term “spraying device” here means an apparatus, which permits the spraying of a liquid without using a propellant. For example, spray pumps or elastic containers provided with a spray valve, in which the cosmetic agent according to the invention has been filled under pressure, are suitable mechanical spraying devices. In operation the agent is continuously dispensed from the filled expanded elastic container when the user opens the spray valve.

The composition according to the invention is preferably used as a rinse-off product, but also as a leave-on product. In a typical application as a rinse-off product a quantity of the agent sufficient to achieve the desired conditioning effect is distributed on wet or moist hand-towel-dried hair after washing the hair. The quantity employed depends on the hair abundance and amounts to typically about 1 to 25 g, preferably 3 to 10 g. After a sufficient acting time, for example 1 to 15 minutes, the hair is rinsed. In case only a gentle conditioning effect is desired, it can be rinsed out immediately. Subsequently the hair is combed as needed or set in a hair-do and dried.

When the composition according to the invention is used as a leave-on product preferably from 0.5 to 3.0 g of the product are worked into moist or dry hair. The cuticle is smoothed and undesired curling removed. The composition imparts luster, stylability, control and structure to the hair.

The following examples illustrate the above-described invention in more detail, but the details in these examples should not be considered as limiting the claims appended hereinbelow. In the following examples % means percent by weight and relates to the total amount of the final product.

EXAMPLES

Example 1

Manufacture of a Hair Conditioning Agent in the form of a Liquid Crystal Gel

Cetearyl alcohol in an amount of 4.0 g was heated together with the heat-stable oil-soluble ingredients (1.0 g paraffin oil, 0.1 g propylparabene) at 80° C. The non-heat sensitive, water-soluble ingredients (4.0 g of 50% solution of cetyltrimonium chloride—GENAMIN® CTAC 50—in isopropanol, and 0.1 g of methylparabene) were dissolved at 80° C. in the largest part of the water. Both phases were combined at 80° C., stirred for five minutes at this temperature and subsequently cooled with stirring. Besides the phenylpropyldimethylsiloxysilicate (1.5 g SILSHINE® 151) also the silicone Amodimethicone (1.0 g) and the other ingredients (4.0 g propylene glycol, 0.5 g perfume oil, 1.0 g GLUADIN® APG, 0.1 g PARSOL® 1789) are worked in and water is added to 100 g.

The evaluation of these conditioners took place according to the so-called half side comparison, in which first the entire head is washed with a shampoo and subsequently the left half side is treated with a test sample (conditioner 2, 3 or 4) and the right half side is treated with a composition according to the invention (conditioner 1). Both sides were rinsed out at the same time and subsequently dried with a hand towel. Subsequently the feel, combability and load of the hair in the moist state on both sides were compared. After that the entire head was styled and dried. The evaluation occurred in the dry state.

The feel, combability, luster and manageability of prior art conditioners 2, 3 and 4 were clearly inferior to that of conditioner 1 according to the invention in this test, especially for Asiatic hair. Furthermore the characteristic properties of conditioner 1 are clearly within a range necessary for the Shittori style.
