Cosmetic compositions containing a particular aminosilicone and a thickener, and uses thereof

## Abstract

A novel cosmetic composition comprising, in a cosmetically acceptable medium, at least one aminosilicone of as defined herein having, for example, a contact angle ranging from 90° to 180° and at least one thickener, being able to afford at least one improved cosmetic property (such as lightness, disentangling, volume and sheen) and/or at least one of long-lasting and remanent effects, as well as uses of the composition, such as for washing and/or conditioning keratin materials such as the hair or the skin.

## Background
Disclosed herein is a novel cosmetic composition comprising, in a cosmetically acceptable medium, at least one particular aminosilicone and at least one thickener.
It is well known that hair that has been sensitized (i.e. damaged and/or embrittled) to varying degrees by the action of atmospheric agents or by the action of mechanical or chemical treatments, such as dyeing, bleaching and/or permanent-waving, may often be difficult to disentangle and to style, and may lack softness.
It has already been recommended, in compositions for washing or caring for keratin materials such as the hair, to use conditioners, such as cationic polymers and silicones, to facilitate the disentangling of the hair and to impart softness and suppleness thereto. However, at least one of the cosmetic advantages mentioned above can unfortunately also be accompanied, on dried hair, by certain cosmetic effects considered undesirable, namely a lank effect on the hairstyle (lack of lightness of the hair) and a lack of smoothness (hair not uniform from the root to the end).
In addition, the use of aminosilicones for this purpose can have various drawbacks. On account of their strong affinity for hair, some of these silicones can become deposited in considerable amount during repeated use, and can lead to adverse effects such as an unpleasant, laden (charged or loaded) feel, stiffening of the hair and adhesion between fibres, affecting the styling. These drawbacks can be accentuated in the case of fine hair, which lacks liveliness and volume.
Furthermore, although aminosilicone microemulsions show particularly good performance, they can be difficult to formulate in hair compositions, these compositions being found to be of lower performance, for example by, showing poor remanence.
In summary, it is found that the current cosmetic compositions containing aminosilicones are not always entirely satisfactory.
The inventors have now discovered that the combination of at least one particular aminosilicone with at least one thickener makes it possible to overcome at least one of these drawbacks.
The inventors have now found that a composition comprising at least one aminosilicone as defined below and at least one thickener, makes it possible to limit or even eliminate at least one of the lack of sheen, smoothness and softness of the hair, while at the same time retaining at least one of the other advantageous cosmetic properties associated with compositions containing a silicone.
The composition disclosed herein can lead to an optimization of the deposition of silicone onto keratin materials.
The composition disclosed herein can also afford at least one improved cosmetic property (such as lightness, softness, disentangling, a natural feel together with great ease of styling, and sheen) and, what is more, the effects can be persistent and remanent to, for example, withstand shampooing several times.
The composition disclosed herein when applied to the skin, such as in the form of a bubble bath or shower gel, can afford an improvement in the softness of the skin.
Thus, novel cosmetic compositions are now proposed, comprising, in a cosmetically acceptable medium, at least one aminosilicone as defined below and at least one thickener.
Another new embodiment relates to the inclusion of at least one aminosilicone as defined below, in, or for the manufacture of, a cosmetic composition comprising at least one thickener.
Another new embodiment relates to a composition comprising at least one aminosilicone as defined below and at least one thickener, as well as methods, for conditioning a keratin material.
Another new embodiment relates to a composition comprising at least one aminosilicone as defined below and at least one thickener, as well as methods, for improving the lightness softness, sheen and/or disentangling, and/or facilitating the styling of a keratin material.
Another new embodiment relates to a composition comprising at least one aminosilicone as defined below and at least one thickener, as well as methods, for improving the remanence of, for example, the conditioning effects with respect to shampooing.
Various illustrative new embodiments will now be described in detail. All the meanings and definitions of the compounds given below are valid for all new embodiments.
In context, the term “thickener” means any agent whose function is to increase the viscosity of the composition.
The term “keratin materials” means hair, eyelashes, eyebrows, skin, nails, mucous membranes or scalp.
In one new embodiment, the at least one aminosilicone is chosen from aminosilicones of formulae (I) and (II) below:




in which:

    m and n are numbers such that the sum (n+m) ranges, from 1 to 1000, further, for example, from 50 to 250 and even further, for example, from 100 to 200, n is a number ranging from 0 to 999, further, for example, from 49 to 249 and even further, for example, from 125 to 175, and m is a number ranging from 1 to 1000, further, for example, from 1 to 10 and even further, for example, from 1 to 5; R1, R2 and R3, which may be identical or different, are chosen from hydroxyl and C1–C4 alkoxy radicals, wherein at least one of the radicals R1, R2, and R3, for example, is chosen from C1–C4 alkoxy radicals.


In one embodiment, the alkoxy radical is a methoxy radical.
The hydroxyl/alkoxy molar ratio may range, for example, from 0.2:1 to 0.4:1, further, for example, from 0.25:1 to 0.35:1 and even further, for example, is equal to 0.3:1.
The weight-average molecular mass of the at least one aminosilicone of formula (I) ranges, for example, from 2000 to 1 000 000 and further, for example, from 3500 to 200 000.




in which:

    p and q are numbers such that the sum (p+q) ranges, from 1 to 1000, further, for example, from 50 to 350 and even further, for example, from 150 to 250, p is a number ranging, from 0 to 999, further, for example, from 49 to 349 and even further, for example, from 159 to 239, and q is a number ranging, for example, from 1 to 1000, further, for example, from 1 to 10 and even further, for example, from 1 to 5; R1 and R2, which are different, are chosen from hydroxyl and C1–C4 alkoxy radicals, wherein at least one of the radicals R1 and R2, for example, is chosen from C1–C4 alkoxy radicals.


In one embodiment, the alkoxy radical is a methoxy radical.
The hydroxyl/alkoxy molar ratio may range, for example, from 1:0.8 to 1:1.1, further, for example, from 1:0.9 to 1:1 and even further, for example, is equal to 1:0.95.
The weight-average molecular mass of the at least one aminosilicone of formula (II) ranges, for example, from 2000 to 200 000, further, for example, from 5000 to 100 000 and even further, for example, from 10 000 to 50 000.
The weight-average molecular mass of the at least one aminosilicone is measured by Gel Permeation Chromatography (GPC) at room temperature, as polystyrene equivalents. The columns used are styragel μ columns. The eluent is THF and the flow rate is 1 ml/minute. 200 μl of a solution at 0.5% by weight of silicone in THF are injected. The detection is performed by refractometry and UV-metry.
The commercial products corresponding to the at least one aminosilicone of formula (I) or (II) can include in their composition at least one other aminosilicone whose structure is different from the formulae (I) and (II).
A product containing the at least one aminosilicone of formula (I), is sold by the company Wacker under the name Belsil ADM 652®.
Products containing aminosilicones of formula (II), mention may be made, for example, of a product sold by Wacker under the name Fluid WR 1300®.
In one new embodiment, the at least one aminosilicone is used in the form of an oil-in-water emulsion. The oil-in-water emulsion may comprise at least one surfactant.
The at least one surfactant may be of any nature, for example, cationic and/or nonionic.
The number-average size of the at least one aminosilicone particle (i.e., the mean particle size of the at least one aminosilicone) in the emulsion ranges, for example, from 3 to 500 nanometers. Such particle sizes are measured with a laser granulometer.
For example, the mean particle size of the at least one aminosilicone of formula (II) in the microemulsion, ranges, for example, from 5 to 60 nanometres and further, for example, from 10 to 50 nanometres. Such particle sizes can be measured by one skilled in the art using ordinary techniques.
An example of the microemulsions of the aminosilicone of formula (II) is sold under the name Finish CT 96 E® or SLM 28020® by the company Wacker.
In one embodiment, the at least one aminosilicone is chosen, for example, such that the contact angle with water of a hair treated with a composition comprising 2% (active materials) of the said at least one aminosilicone ranges, for example, from 90 to 180° and further, for example, from 90 to 130°. As used herein, a range “from x to y” includes within the range the endpoints x and y.
To measure the contact angle, the at least one aminosilicone is, for example, dissolved or dispersed in a solvent for the aminosilicone or for the aminosilicone emulsion, for example, hexamethyldisiloxane or water depending on the hydrophilicity of the silicone.
In another embodiment, the composition comprising the at least one aminosilicone chosen from aminosilicones of formulae (I) and (II) is such that the contact angle of a hair treated with the said composition ranges, for example, from 90 and 180° and further, for example, from 90 to 130°.
The contact angle measurement is based on immersion of a hair in distilled water. The measurement includes evaluating the force exerted by the water on the hair during its immersion in distilled water and the force exerted by the water on the hair during its removal. The forces thus measured are directly linked to the contact angle θ existing between the water and the surface of the hair. The hair is hydrophilic when the angle θ ranges from 0 to less than 90°, and hydrophobic when the angle 0 ranges from 90° to 180°.
The test is carried out with locks of natural hair that have been bleached under the same conditions and then washed.
Each 1 g lock is placed in a crystallizing dish 75 mm in diameter and then covered uniformly with 5 ml of the formulation to be tested. The lock is thus left for 15 minutes at room temperature and then rinsed with distilled water for 30 seconds. The drained lock is left in the open air until it is completely dry.
For each evaluation, 10 hair strands that have undergone the same treatment are analysed. Each sample, attached to a precision microbalance, is immersed via its end in a container filled with distilled water. This DCA balance (“Dynamic Contact Angle Analyser”), from the company Cahn Instruments, allows the force (F) exerted by the water on the hair to be measured.
In parallel, the perimeter (P) of the hair is measured by means of observation by microscope.
The mean wettability force on 10 hair strands and the section of the analysed hairs make it possible to obtain the contact angle of the hair on the water, according to the formula:

F=P*┌lv*cos θ

where F is the wettability force expressed in Newtons, P is the perimeter of the hair in meters, ┌lv is the liquid/water vapour interface tension in J/m2 and θ is the contact angle.

The product SLM 28020® from Wacker at 12% in water (i.e. 2% aminosilicone as active materials) gives a contact angle of 93° according to the test indicated above.
The product Belsil ADM 652 from Wacker at 2% in hexamethyldisiloxane (i.e. 2% aminosilicone as active materials) gives a contact angle of 111° according to the test indicated above.
The at least one aminosilicone chosen from aminosilicones of formulae (I) and (II) is, for example, used in an amount ranging from 0.01% to 20% by weight relative to the total weight of the composition. As a further example, this amount ranges from 0.1% to 15% by weight and, further, for example, from 0.5% to 10% by weight, relative to the total weight of the composition.
The at least one thickener is chosen, for example, from:

    (i) associative thickeners;
    (ii) crosslinked acrylic acid homopolymers;
    (iii) crosslinked copolymers of (meth)acrylic acid and of (C1–C6)alkyl acrylate;

(6) copolymers of hydrophilic acrylates or methacrylates and of hydrophobic monomers comprising at least one fatty chain, such as polyethylene glycol methacrylate/lauryl methacrylate copolymer.
The anionic amphiphilic polymers comprising at least one hydrophilic unit and at least one fatty-chain unit, may, for example, be chosen from those comprising at least one fatty-chain allyl ether unit and at least one hydrophilic unit comprising an ethylenic unsaturated anionic monomeric unit, for example, a vinylcarboxylic acid unit and further, for example, chosen from units derived from acrylic acids, methacrylic acids and mixtures thereof, wherein the fatty-chain allyl ether unit corresponds to the monomer of formula (III) below:

In one embodiment, a unit of formula (III) is, for example, a unit in which R1 can be H, n can be equal to 10 and R can be a stearyl (C18) radical.
Anionic amphiphilic polymers of this type are described and prepared, according to an emulsion polymerization process, in patent EP-0 216 479 B2.
In one embodiment, anionic amphiphilic polymers are, for example, polymers formed from 20% to 60% by weight of acrylic acid and/or of methacrylic acid, from 5% to 60% by weight of lower alkyl (meth)acrylates, from 2% to 50% by weight of fatty-chain allyl ether of formula (III), and from 0% to 1% by weight of a crosslinking agent which is a well-known copolymerizable unsaturated polyethylenic monomer, for example, diallyl phthalate, allyl (meth)acrylate, divinylbenzene, (poly)ethylene glycol dimethacrylate and methylenebisacrylamide.
Examples of such polymers are crosslinked terpolymers of methacrylic acid, of ethyl acrylate and of polyethylene glycol (10 EO) stearyl ether (Steareth-10), such as those sold by the company Ciba under the names Salcare SC 80 and Salcare SC 90, which are aqueous 30% emulsions of a crosslinked terpolymer of methacrylic acid, of ethyl acrylate and of steareth-10 allyl ether (40/50/10).
The anionic amphiphilic polymers may further be chosen, for example, from those comprising at least one hydrophilic unit of unsaturated olefinic carboxylic acid type, and at least one hydrophobic unit of the type such as a (C10–C30) alkyl ester of an unsaturated carboxylic acid.

(vi) The polysaccharides are, for example, chosen from glucans, modified and unmodified starches (such as those derived, for example, from cereals, for instance wheat, corn or rice, from vegetables, for instance yellow pea, and tubers, for instance potato or cassava), amylose, amylopectin, glycogen, dextrans, celluloses and derivatives thereof (methylcelluloses, hydroxyalkylcelluloses, ethyl hydroxyethylcellu loses, and carboxymethylcelluloses), mannans, xylans, lignins, arabans, galactans, galacturonans, chitin, chitosans, glucuronoxylans, arabinoxylans, xyloglucans, glucomannans, pectic acids and pectins, alginic acid and alginates, arabinogalactans, carrageenans, agars, glycosaminoglucans, gum arabics, gum tragacanths, ghatti gums, karaya gums, carob gums, galactomannans, such as guar gums, and nonionic derivatives thereof (hydroxypropyl guar) and xanthan gums, and mixtures thereof.
For example, the polysaccharides that may be used are chosen from those described, for example, in “Encyclopedia of Chemical Technology”, Kirk-Othmer, Third Edition, 1982, volume 3, pp. 896–900, and volume 15, pp. 439–458, in “Polymers in Nature” by E. A. MacGregor and C. T. Greenwood, published by John Wiley & Sons, Chapter 6, pp. 240–328,1980, and in “Industrial Gums—Polysaccharides and their Derivatives”, edited by Roy L. Whistler, Second Edition, published by Academic Press Inc., the content of these three publications being entirely incorporated by reference.
For example, starches, guar gums and celluloses and derivatives thereof can be used.
Among the starches that may be used, mention may be made, for example, of macromolecules in the form of polymers comprising elemental moieties that are anhydroglucose units. The number of these moieties and their assembly make it possible to distinguish between amylose (linear polymer) and amylopectin (branched polymer). The relative proportions of amylose and of amylopectin, and also their degree of polymerization, can vary as a function of the botanical origin of the starches.
The botanical origin of the starch molecules used may be cereals or tubers. Thus, the starches can be, for example, chosen from corn starch, rice starch, cassava starch, tapioca starch, barley starch, potato starch, wheat starch, sorghum starch and pea starch.
Starches are generally in the form of a white powder, which is insoluble in cold water and which has an elementary particle size ranging from 3 to 100 microns.
The starches may optionally be C1–C6 hydroxyalkylated or C1–C6 acylated (such as acetylated). The starches may also have undergone heat treatments.
Distarch phosphates or of compounds rich in distarch phosphate, for instance the products sold under the references Prejel VA-70-T AGGL (gelatinized hydroxypropylated cassaya distarch phosphate) or Prejel TK1 (gelatinized cassaya distarch phosphate) or Prejel 200 (gelatinized acetylated cassaya distarch phosphate) by the company Avebe, or Structure ZEA from National Starch (hydroxypropylated corn distarch phosphate), may also be used.
The guar gums may be modified or unmodified.
The unmodified guar gums are, for example, the products sold under the name Vidogum GH 175 by the company Unipectine and under the names Meyro-Guar 50 and Jaguar C by the company Meyhall.
The modified nonionic guar gums are, for example, modified with C1–C6 hydroxyalkyl groups.
Among hydroxyalkyl groups, mention may be made, for example, of hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups.
These guar gums are well known in the state of the art and can be prepared, for example, by reacting corresponding alkene oxides, such aspropylene oxides, with guar gum so as to obtain a guar gum modified with hydroxypropyl groups.
The degree of hydroxyalkylation, which corresponds to the number of alkylene oxide molecules consumed by the number of free hydroxyl functions present on the guar gum, may, for example, range from 0.4 to 1.2.
Such nonionic guar gums optionally modified with hydroxyalkyl groups are sold, for example, under the trade names Jaguar HP8, Jaguar HP60 and Jaguar HP120, Jaguar DC 293 and Jaguar HP 105 by the company Rhodia Chimie (Meyhall) or under the name Galactasol 4H4FD2 by the company Aqualon.
Among the celluloses that are used are, for example, hydroxyethylcellulose and hydroxypropylcelluloses. Mention may be made of the products sold under the names Klucel EF, Klucel H, Klucel LHF, Klucel MF and Klucel G by the company Aqualon.
(vii) The fatty alcohols are, for example, chosen from myristyl alcohol, cetyl alcohol, stearyl alcohol and behenyl alcohol.
