Description:
"DETERGENT COSMETIC COMPOSITIONS COMPRISING FOUR SURFACTANTS, A CATIONIC POLYMER AND A SILICONE, AND USE THEREOF"

The present invention relates to novel detergent cosmetic compositions for keratin materials, in particular human keratin fibres such as the hair, comprising, in a cosmetically acceptable aqueous support, at least one anionic surfactant, at least one ethoxylated alkyl sulfate anionic surfactant other than the preceding one, at least one amphoteric surfactant and at least one nonionic surfactant of alkylpolyglycoside type, at least one non-silicone cationic polymer and at least one silicone. The invention also relates to the use of the said compositions in the abovementioned cosmetic application.

It is well known that hair is sensitized or embrittled to varying degrees by the action of atmospheric agents and especially light, water and moisture, and also repeated mechanical or chemical treatments such as brushing, combing, washing, bleaching, permanent-waving, relaxing and/or dyeing.

Attack due to chemical and mechanical treatments has consequences especially on the qualities of the keratin fibre and may lead to difficult disentangling at the time of washing the hair, on dry hair and/or wet hair, and also to degradation of the surface properties of the fibres, which become non-smooth and irregular at the surface, more particularly when the hair is dry.

Many publications moreover disclose that natural light destroys certain amino acids of the hair. These attacking factors impair the hair fibre and reduce its mechanical properties such as the tensile strength, the breaking load and the elasticity, or its resistance to swelling in an aqueous medium. The hair is dull, coarse and brittle. The hair is difficult to disentangle and to style.

It is also known especially that light and washing agents have a tendency to attack the natural colour of hair and also the artificial colour of dyed hair. The colour of the hair gradually fades or turns towards unaesthetic or undesirable shades.

Substances for protecting the hair against the degradation caused by atmospheric attacking factors, such as light, heat and treatments, have been known for many years in the cosmetics industry. In particular, products that improve the cosmetic properties (especially the disentangling, the softness, the smoothness, the gloss, etc.) and products that protect the colour of naturally coloured or artificially dyed keratin fibres and that preserve or reinforce the intrinsic mechanical properties of keratin fibres (the tensile strength, the breaking load and the elasticity, or their resistance to swelling in an aqueous medium) are sought.

Moreover, the skin may also be impaired to varying degrees by the action of atmospheric agents and also by the repeated action of detergents. Skin tissue may be burned, and the skin becomes dry and coarse and loses its natural elasticity. The onset of dandruff, excess seborrhoea or, conversely, excess dryness may then be observed.

In the field of "rinse-out" cosmetic compositions, such as shampoos, shower gels, facial makeup removers or shaving foams, detergent compositions comprising agents that are beneficial to the hair or the skin are known. These beneficial ingredients are generally introduced into the composition to facilitate the disentangling of the hair, to improve the feel qualities of the keratin fibre or of the skin, or alternatively to promote their moisturization. Cationic polymers, silicones and emollients such as polyols constitute, in this context, the ingredients most commonly used.

To obtain the expected beneficial effect, it is necessary to introduce an amount of beneficial agent into the rinse-out composition that is much higher than the amount needed to obtain the effect. For rinse-out detergent compositions, the majority of the beneficial agent is in point of fact removed during the rinsing of the composition, and the effective part of the agent contained in the composition is consequently very low.

Moreover, repeated applications of compositions of the prior art often have the effect of giving the hair an unpleasant feel, loss of volume and liveliness of the hair, and occasionally loss of sheen.

Moreover, a persistent greasy feel on the skin is obtained with such compositions.

Thus, at the present time, no rinse-out detergent compositions exist that can substantially increase the amount of beneficial agent vectorized after rinsing. Such compositions would make it possible to use much less beneficial agent to afford the same level of beneficial effect.

The Applicant has discovered, surprisingly, that by using, in a cosmetically acceptable medium, at least one combination of four surfactants and of a cationic polymer in combination with at least one water-insoluble silicone, the drawbacks mentioned above can be overcome.

In particular, it is possible to increase the deposition of silicone and thereby to increase the efficacy of the said silicone or to reduce the amount of the said agent used.

One subject of the invention is thus a detergent cosmetic composition, characterized in that it comprises:

(A) one or more anionic surfactants chosen from ethoxylated alkyl sulfates, the corresponding acids, and mixtures thereof, and

(B) one or more anionic surfactants other than the surfactant(s) (A), (C) one or more amphoteric or zwitterionic surfactants,

(D) one or more alkylpolyglycoside nonionic surfactants,

(E) one or more non-silicone cationic polymers preferably with a cationic charge density of less than 4 meq./g and

(F) one or more silicones,

the ethoxylated alkyl sulfate anionic surfactant/anionic surfactant (B) weight ratio ranging from 0.5 to 1.

In particular, it has been found that by using a cosmetic composition as defined above, it spreads easily over the hair and the scalp, generating an abundant and soft foam that is easy to remove with water leaving the hair clean, shiny, feeling and looking smooth, and easy to disentangle. The composition according to the invention shows good stability on storage.

Without wishing to limit the present invention to any theory, there would appear to be, during rinsing, particular interactions and/or affinities between the combination of surfactants in accordance with the invention, the cationic polymer and the hair, which promote uniform, substantial and long-lasting deposition of the silicone and of the cationic polymer onto the surface of the said hair, this qualitative and quantitative deposition probably being one of the reasons for the improvement observed as regards the final properties, in particular the ease of styling, the disentangling, the smoothness, the softness and the sheen of treated hair when a conditioning agent is used.

All these discoveries form the basis of the present invention.

A subject of the invention is also the use of at least one composition comprising:

(A) one or more anionic surfactants chosen from ethoxylated alkyl sulfates, the corresponding acids, and mixtures thereof, and

(B) one or more anionic surfactants other than the surfactant(s) (A),

(C) one or more amphoteric or zwitterionic surfactants,

(D) one or more alkylpolyglycoside nonionic surfactants,

(E) one or more non-silicone cationic polymers preferably with a cationic charge density of less than 4 meq./g and

(F) one or more silicones,

the ethoxylated alkyl sulfate anionic surfactant/anionic surfactant (B) weight ratio ranging from 0.5 to 1 , to improve the deposition and/or fixing of the silicone(s) to the keratin materials and/or to increase the efficacy of the silicone(s) on the keratin materials. A subject of the invention is also the cosmetic use of the above compositions for cleansing and/or removing makeup from and/or conditioning keratin materials such as the hair and the skin.

The cationic charge density of a polymer corresponds to the number of moles of cationic charges per unit mass of polymer under conditions in which it is totally ionized. It may be determined by calculation if the structure of the polymer is known, i.e. the structure of the monomers constituting the polymer and their mole proportion or weight proportion. It may also be determined experimentally via the Kjeldahl method, generally at a pH of about 7 at room temperature.

The cationic polymers that may be used in accordance with the present invention may be selected from any of those already known per se to enhance the cosmetic properties of hair treated with detergent compositions, these being, in particular, the polymers described in patent application EP-A-0 337 354 and in French patent applications FR-A-2 270 846, 2 383 660, 2 598 611 , 2 470 596 and 2 519 863.

The term "cationic polymer" means a polymer that is positively charged when it is contained in the composition according to the invention. This polymer may bear one or more positive permanent charges or may contain one or more cationizable functions in the composition according to the invention.

Examples that may be mentioned especially include fatty acid esters preferably containing from 8 to 22 carbon atoms, for instance isopropyl myristate, isopropyl palmitate, 2- ethylhexyl palmitate, purcellin oil (stearyl octanoate), isononyl or isostearyl isononanoate, and isopropyl lanolate, and mixtures thereof. Mention may also especially be made of esters of fatty alcohols preferably containing from 8 to 22 carbon atoms.

The detergent compositions according to the invention have a final pH generally of between 3 and 8. Preferably, this pH is between 4 and 7.5. The pH may be adjusted to the desired value conventionally by adding a base (organic or mineral) to the composition, for example sodium hydroxide, aqueous ammonia or a primary, secondary or tertiary (poly)amine, for instance monoethanolamine, diethanolamine, triethanolamine, isopropanolamine or 1 ,3-propanediamine, or alternatively by adding a mineral or organic acid, preferably citric acid or hydrochloric acid.

The composition according to the invention comprises water or a mixture of water and of one or more organic solvents such as C1-C4 lower alcohols such as ethanol, isopropanol, tert-butanol or n-butanol; polyols such as propylene glycol, hexylene glycol or glycerol.

The composition according to the invention preferably comprises at least 30% by weight, more particularly from 50% to 90% by weight and more preferably from 70% to 85% by weight of water relative to the total weight of the composition.

The compositions in accordance with the invention may also contain up to 5% of nacreous agents or opacifiers that are well known in the state of the art, for instance fatty alcohols especially of C16 to C24, sodium palmitate or magnesium palmitate, sodium or magnesium stearate or hydroxy-stearate, fatty alcohols, fatty-chain acyl derivatives such as ethylene glycol or polyethylene glycol distearates, and fatty- chain ethers, for instance distearyl ether or 1-(hexadecyloxy)-2-octadecanol.

The compositions according to the invention may also contain foam synergists such as C10-C18 1 ,2-alkanediols or C10-C18 fatty alkanolamides derived from monoethanolamine or from diethanolamine.

The compositions according to the invention may also contain additives such as natural or synthetic, anionic, amphoteric, zwitterionic, nonionic or cationic, associative or non-associative polymeric thickeners, non-polymeric thickeners, for instance acids or electrolytes, fragrances, dyes, mineral or organic particles, preserving agents, and pH stabilizers.

Among the thickeners, mention may be made in particular of scleroglucans, xanthan gums, fatty acid alkanolamides, alkyl ether carboxylic acid alkanolamides optionally oxyethylenated with up to 5 mol of ethylene oxide, such as the product sold under the name Aminol A15 by the company Chem Y, crosslinked polyacrylic acids and crosslinked acrylic acid/C10-C30 alkyl acrylate copolymers.

A person skilled in the art will take care to select the optional additives and the amount thereof such that they do not harm the properties of the treatment compositions.

These additives are present in the composition according to the invention in an amount ranging from 0 to 20% by weight relative to the total weight of the composition.

Needless to say, a person skilled in the art will take care to select this or these optional additional compounds such that the advantageous properties intrinsically associated with the cosmetic composition in accordance with the invention are not, or are not substantially, adversely affected by the envisaged addition(s).

These compositions may be in the form of more or less thick and liquids, creams or gels, foams, waxes, W/O or O/W emulsions or multiple emulsions, and they are mainly suitable for washing keratin materials and in particular the hair and the skin, even more particularly the hair.

A subject of the invention is also a process for washing and conditioning keratin materials especially such as the hair, which consists in applying to the said wet keratin materials an effective amount of a composition as defined above, and then in rinsing with water after an optional leave-on time.

The compositions according to the invention are preferably used as shampoos for washing and conditioning the hair, and they are applied, in this case, to wet hair in amounts that are suitable to wash them, and the lather generated by massaging or rubbing with the hands is then removed after an optional leave-on time, by rinsing with water, the operation possibly being repeated one or more times.

The compositions in accordance with the invention may also be used as shower gels for washing and conditioning the hair and/or the skin, in which case they are applied to wet skin and/or hair and are rinsed off after application.

Preferably, the compositions according to the invention are used on the hair. Concrete but in no way limiting examples illustrating the invention will now be given. The percentages are given on the basis of active materials.

To evaluate the cosmetic impact of the two compositions A and B, the force required on combing dry hair at 25°C and 40% relative humidity after treating natural wet hair with compositions A and B at room temperature in a proportion of 0.4 g of composition per gram of hair, massaging for 15 seconds and rinsing and drying, was quantified.

This test is performed on an automatic combing machine formed from two combs and a lock support connected to a force sensor.

The combs pass through the lock from top to bottom and, on each passage (32 in total), the combing force is detected. The general average combing force is then used as the basis.

The following results are obtained:

Composition A thus allows greater ease of combing.
