SOLID COMPOSITION WITH A VINYL POLYMER BEARING A

CARBOSILOXANE DENDRIMER UNIT AND TWO INCOMPATIBLE PHENYL SILICONE OILS, AND TREATMENT PROCESS

The present invention relates to an anhydrous solid cosmetic composition comprising a mixture of two incompatible phenyl silicone oils with a particular film- forming polymer, and also to a lip makeup and/or care process using the same.

Solid cosmetic compositions for making up and/or caring for the skin and/or the lips must satisfy several conditions regarding their mechanical characteristics and, quite obviously, regarding their performance qualities at the time of application of the composition, and also their evolution over time, once the composition is in place.

Thus, solid care and/or makeup compositions generally contain one or more fatty substances structured with a "structuring" or "gelling" agent, conventionally a wax or a polymer, to improve the stiffness of the compositions and especially to obtain solid compositions, preferably in the form of wands, which remain stable.

Needless to say, the galenical form of these compositions must, on the one hand, satisfy mechanical requirements in order to ensure the glidance and persistence of the stick during application and to prevent it from breaking, and, on the other hand, satisfy requirements in terms of transfer qualities so as to ensure comfortable application and also a sufficient and good-quality deposit on the lips.

Furthermore, the deposited film must be sufficiently fine, non-tacky, and must not be too greasy or, on the other hand, give rise to any sensation of tautness. Finally, it should have a suitable level of gloss and have good persistence.

It is known practice to use, in cosmetic compositions, vinyl polymers bearing at least one carbosilaxane dendrimer-based unit, whose presence improves the persistence of the deposited film.

However, it is observed that the deposit lacks comfort, that it is insufficiently homogeneous, and may be considered slightly too tacky, and in some cases exhibits some heterogeneities in the color.

The aim of the present invention is thus to overcome the drawbacks described above.

Thus, one subject of the present invention is an anhydrous solid cosmetic composition comprising:

a) at least one non- volatile phenyl silicone first oil not bearing any dimethicone fragments;

b) at least one non- volatile phenyl silicone second oil bearing at least one dimethicone fragment;

c) at least one vinyl polymer comprising at least one carbosiloxane dendrimer-based unit. The invention also relates to a process for making up and/or caring for the lips, in which the abovementioned composition is applied to the lips.

The composition according to the invention has the advantage of being glidant and very easy to apply. It delivers a fine, homogeneous, without heterogeneities of the color, non-greasy and non-tacky film of composition, which remains comfortable after application. The deposit also shows good persistence over time on the lips, as well as an improved resistance to migration.

The present invention will emerge more clearly on reading the description and the examples that follow.

It should be noted that, in the remainder of the description, unless otherwise indicated, the limits indicated for a range are included in the said range.

The expressions "at least one" and "several" are used without distinction.

The term "anhydrous" especially means that water is preferably not deliberately added to the compositions, but may be present in trace amounts in the various compounds used in the compositions.

The temperatures indicated later are indicated at atmospheric pressure (1.013 x 10 ⁵

Pa).

The cosmetic composition according to the invention is a composition more particularly intended for making up and/or caring for the skin or the lips. Preferably, the composition according to the invention is intended for making up and/or caring for the lips, and even more preferentially for making up the lips.

As indicated previously, the composition according to the invention is in a solid form. In particular, it may be in the form of a stick (wand, pen) or in a form cast in a dish or in ajar.

Preferably, it is a lip balm or a lipstick, which is even more preferentially in the form of a stick (wand).

The hardness of the composition is measured according to the following protocol:

Protocol for measuring the hardness

The lipstick is stored at 20°C for 24 hours before measuring the hardness.

The hardness may be measured at 20°C via the "cheese wire" method, which consists in transversely cutting a wand of product, which is preferably a circular cylinder, by means of a rigid tungsten wire 250 μιη in diameter, by moving the wire relative to the stick at a speed of 100 mm/minute.

The hardness of the samples of compositions of the invention, expressed in Nm ^"1 , is measured using a DFGS2 tensile testing machine from the company Indelco-Chatillon.

The measurement is repeated three times and then averaged. The average of the three values read using the tensile testing machine mentioned above, noted Y, is given in grams. This average is converted into newtons and then divided by L which represents the longest distance through which the wire passes. In the case of a cylindrical wand, L is equal to the diameter (in metres).

The hardness is converted into Nm ¹ by the equation below:

(Y x 10 ^"3 x 9.8)/L

For a measurement at a different temperature, the stick is stored for 24 hours at this new temperature before the measurement.

According to this measuring method, the composition according to the invention advantageously has a hardness at 20°C and at atmospheric pressure of greater than or equal to 40 Nm ^"1 . According to one particular mode, the hardness at 20°C and at atmospheric pressure is greater than or equal to 60 Nm ^"1 .

Preferably, the composition according to the invention has a hardness at 20°C of less than 500 Nm ^"1 , especially less than 400 Nm ^"1 and preferably less than 300 Nm ^"1 .

Preferably, the composition has a hardness of between 60 and 150 Nm ^"1 .

NON- VOLATILE SILICONE FIRST OILS

The composition according to the invention comprises at least one non- volatile phenyl silicone first oil not bearing any dimethicone fragments.

The term "silicone oil" means an oil containing at least one silicon atom, and in particular containing Si-0 groups.

The term "phenyl" specifies that the said oil comprises in its structure a phenyl radical.

The term "dimethicone fragment" denotes a divalent siloxane group in which the silicon atom bears two methyl radicals, this group not being located at the ends of the molecule. It may be represented by the following formula: -(Si(CH ₃ ) ₂ -0)-.

The term "non- volatile" is intended to mean an oil of which the vapour pressure at 25°C and atmospheric pressure is non-zero and is less than 0.02 mmHg (2.66 Pa) and better still less than 10 ^"3 mmHg (0.13 Pa).

The vinyl polymer comprising the carbosiloxane dendrimer according to the invention may be manufactured according to the process for manufacturing a branched silalkylene siloxane described in Japanese patent application Hei 9-171 154.

For example, it may be produced by subjecting an organosilicon compound containing a hydrogen atom linked to a silicon atom, represented by the following general formula (IV):

R being as defined above in formula (I),

and an organosilicon compound containing an alkenyl group, to a hydrosilylation reaction.

In the above formula, the organosilicon compound may be represented by 3- methacryloxypropyltris(dimethylsiloxy)silane, 3-acryloxypropyltris(dimethylsiloxy)silane and 4-vinylphenyltris(dimethylsiloxy)silane. The organosilicon compound that contains an alkenyl group may be represented by vinyltris(trimethylsiloxy)silane, vinyltris(dimethylphenylsiloxy)silane, and 5-hexenyltris(trimethylsiloxy)silane.

The hydrosilylation reaction is performed in the presence of a chloroplatinic acid, a complex of vinylsiloxane and of platinum, or a similar transition metal catalyst.

A vinyl polymer bearing at least one carbosilaxane dendrimer-based unit may be chosen from polymers such that the carbosiloxane dendrimer-based unit is a carbosiloxane dendritic structure represented by formula (III): in which Z is a divalent organic group, "p" is 0 or 1, R ¹ is as defined above in formula (IV) and X ¹ is a silylalkyl group represented by formula (II) as defined above.

In a vinyl polymer bearing at least one carbosiloxane dendrimer-based unit, the polymerization ratio between the components (A) and (B), in terms of the weight ratio between (A) and (B), is within a range from 0/100 to 99.9/0.1, or even from 0.1/99.9 to 99.9/0.1 and preferably within a range from 1/99 to 99/1. A ratio between the components

(A) and (B) of 0/100 means that the compound becomes a homopolymer of component

(B) .

A vinyl polymer bearing at least one carbosiloxane dendrimer-based unit may be obtained by copolymerization of the components (A) and (B), or by polymerization of the component (B) alone.

The polymerization may be a free-radical polymerization or an ionic polymerization, but free-radical polymerization is preferred.

The polymerization may be performed by bringing about a reaction between the components (A) and (B) in a solution for a period of from 3 to 20 hours in the presence of a radical initiator at a temperature of from 50°C to 150°C.

A suitable solvent for this purpose is hexane, octane, decane, cyclohexane or a similar aliphatic hydrocarbon; benzene, toluene, xylene or a similar aromatic hydrocarbon; diethyl ether, dibutyl ether, tetrahydrofuran, dioxane or ethers; acetone, methyl ethyl ketone, methyl isobutyl ketone, diisobutyl ketone or similar ketones; methyl acetate, ethyl acetate, butyl acetate, isobutyl acetate or similar esters; methanol, ethanol, isopropanol, butanol or similar alcohols; octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, hexamethyldisiloxane, octamethyltrisiloxane or a similar organosiloxane oligomer.

A radical initiator may be any compound known in the art for standard free-radical polymerization reactions. The specific examples of such radical initiators are 2,2'- azobis(isobutyronitrile), 2,2'-azobis(2-methylbutyronitrile), 2,2'-azobis(2,4- dimethylvaleronitrile) or similar compounds of azobis type; benzoyl peroxide, lauroyl peroxide, tert-butyl peroxybenzoate, tert-butyl peroxy-2-ethylhexanoate or a similar organic peroxide. These radical initiators may be used alone or in a combination of two or more. The radical initiators may be used in an amount of from 0.1 to 5 parts by weight per 100 parts by weight of the components (A) and (B). A chain-transfer agent may be added. The chain-transfer agent may be 2-mercaptoethanol, butyl mercaptan, n-dodecyl mercaptan, 3-mercaptopropyltrimethoxysilane, a polydimethylsiloxane containing a mercaptopropyl group or a similar compound of mercapto type; methylene chloride, chloroform, carbon tetrachloride, butyl bromide, 3-chloropropyltrimethoxysilane or a similar halogenated compound.

In the manufacture of the polymer of vinyl type, after the polymerization, the unreacted residual vinyl monomer may be removed under conditions of heating under vacuum.

To facilitate the preparation of starting material for cosmetic products, the number- average molecular weight of the vinyl polymer bearing a carbosiloxane dendrimer may be chosen within the range between 3000 and 2 000 000 and preferably between 5000 and 800 000. It may be a liquid, a gum, a paste, a solid, a powder, or any other form. The preferred forms are solutions consisting of the dilution of a dispersion or of a powder in solvents.

The vinyl polymer may be a dispersion of a polymer of vinyl type bearing a carbosiloxane dendrimer structure in its side molecular chain, in a liquid such as a silicone oil, an organic oil, an alcohol or water.

The silicone oil may be a dimethylpolysiloxane having the two molecular ends capped with trimethylsiloxy groups, a copolymer of methylphenylsiloxane and of dimethylsiloxane having the two molecular ends capped with trimethylsiloxy groups, a copolymer of methyl-3,3,3-trifluoropropylsiloxane and of dimethylsiloxane having the two molecular ends capped with trimethylsiloxy groups, or similar unreactive linear silicone oils, and also hexamethylcyclotrisiloxane, octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, dodecamethylcyclohexasiloxane or a similar cyclic compound. In addition to the unreactive silicone oils, modified polysiloxanes containing functional groups such as silanol groups, amino groups and polyether groups on the ends or within the molecular side chains may be used.

The organic oils may be isododecane, liquid paraffin, isoparaffin, hexyl laurate, isopropyl myristate, myristyl myristate, cetyl myristate, 2-octyldodecyl myristate; isopropyl palmitate, 2-ethylhexyl palmitate, butyl stearate, decyl oleate, 2-octyldodecyl oleate, myristyl lactate, cetyl lactate, lanolin acetate, stearyl alcohol, cetostearyl alcohol, oleyl alcohol, avocado oil, almond oil, olive oil, cocoa oil, jojoba oil, gum oil, sunflower oil, soybean oil, camelia oil, squalane, castor oil, cottonseed oil, coconut oil, egg yolk oil, polypropylene glycol monooleate, neopentyl glycol 2-ethylhexanoate or a similar glycol ester oil; triglyceryl isostearate, the triglyceride of a fatty acid of coconut oil, or a similar oil of a polyhydric alcohol ester; polyoxyethylene lauryl ether, polyoxypropylene cetyl ether or a similar polyoxyalkylene ether.

The alcohol may be any type that is suitable for use in combination with a cosmetic product starting material. For example, it may be methanol, ethanol, butanol, isopropanol or similar lower alcohols.

A solution or a dispersion of the alcohol should have a viscosity within the range from 10 to 10 ⁹ mPa at 25°C. To improve the sensory use properties in a cosmetic product, the viscosity should be within the range from 100 to 5 x 10 ⁸ mPa.s.

The solutions and dispersions may be readily prepared by mixing a vinyl polymer bearing at least one carbosiloxane dendrimer-based unit with a silicone oil, an organic oil, an alcohol or water. The liquids may be present in the polymerization step. In this case, the unreacted residual vinyl monomer should be completely removed by heat treatment of the solution or dispersion under atmospheric pressure or reduced pressure.

In the case of a dispersion, the dispersity of the polymer of vinyl type may be improved by adding a surfactant.

Such an agent may be hexylbenzenesulfonic acid, octylbenzenesulfonic acid, decylbenzenesulfonic acid, dodecylbenzenesulfonic acid, cetylbenzenesulfonic acid, myristylbenzenesulfonic acid or anionic surfactants of the sodium salts of these acids; octyltrimethylammonium hydroxide, dodecyltrimethylammonium hydroxide, hexadecyltrimethylammonium hydroxide, octyldimethylbenzylammonium hydroxide, decyldimethylbenzylammonium hydroxide, dioctadecyldimethylammonium hydroxide, beef tallow-trimethylammonium hydroxide, coconut oil-trimethylammonium hydroxide, or a similar cationic surfactant; a polyoxyalkylene alkyl ether, a polyoxyalkylenealkylphenol, a polyoxyalkylene alkyl ester, the sorbitol ester of polyoxyalkylene, polyethylene glycol, polypropylene glycol, an ethylene oxide additive of diethylene glycol trimethylnonanol, and nonionic surfactants of polyester type, and also mixtures.

In the dispersion, a mean particle diameter of the polymer of vinyl type may be within a range of between 0.001 and 100 microns and preferably between 0.01 and 50 microns. The reason for this is that, outside the recommended range, a cosmetic product mixed with the emulsion will not have a nice enough feel in particular on the lips or to the touch, nor sufficient spreading properties nor a pleasant feel.

A vinyl polymer contained in the dispersion or the solution may have a concentration within a range of between 0.1% and 95% by weight and preferably between 5% and 85% by weight. However, to facilitate the handling and the preparation of the mixture, the range should preferably be between 10%> and 75% by weight.

A vinyl polymer that is suitable for use in the invention may also be one of the polymers described in the examples of patent application EP 0 963 751. According to one preferred embodiment, a vinyl polymer grafted with a carbosiloxane dendrimer may be the product of polymerization of:

According to one preferred mode, a vinyl polymer bearing at least one carbosiloxane dendrimer-based unit used in the invention comprises at least one butyl acrylate monomer.

According to one embodiment, a vinyl polymer may also comprise at least one fluoro organic group.

Structures in which the polymerized vinyl units constitute the backbone and carbosiloxane dendritic structures and also fluoro organic groups are attached to side chains are particularly preferred.

The fluoro organic groups may be obtained by replacing with fluorine atoms all or some of the hydrogen atoms of methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tert-butyl, pentyl, neopentyl, hexyl, cyclohexyl, heptyl, octyl, nonyl, decyl, undecyl, dodecyl, tridecyl, tetradecyl, hexadecyl and octadecyl groups and other alkyl groups of 1 to 20 carbon atoms, and also alkyloxyalkylene groups of 6 to 22 carbon atoms.

The wax may especially have a hardness ranging from 0.05 MPa to 15 MPa and preferably ranging from 6 MPa to 15 MPa. The hardness is determined by measuring the compression force, measured at 20°C using the texturometer sold under the name TA- TX2i by the company Rheo, equipped with a stainless-steel cylinder 2 mm in diameter travelling at a measuring speed of 0.1 mm/s, and penetrating the wax to a penetration depth of 0.3 mm.

PASTY FATTY SUBSTANCES

The composition according to the invention may also comprise at least one pasty fatty substance.

For the purposes of the present invention, the term "pasty fatty substance" is intended to denote a lipophilic fatty compound that undergoes a reversible solid/liquid change of state, exhibiting anisotropic crystal organization in the solid state, and that comprises, at a temperature of 23°C, a liquid fraction and a solid fraction.

In other words, the starting melting point of the pasty fatty substance can be less than 23°C. The liquid fraction of the pasty fatty substance measured at 23°C can represent from 9% to 97% by weight of the pasty fatty substance. This liquid fraction at 23°C preferably represents between 15% and 85% and more preferably between 40% and 85% by weight.

For the purposes of the invention, the melting point corresponds to the temperature of the most endothermic peak observed in thermal analysis (DSC) as described in the standard ISO 11357-3; 1999. The melting point of a pasty fatty substance may be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name MDSC 2920 by the company TA Instruments.

The measurement protocol is as follows:

A sample of 5 mg of pasty fatty substance placed in a crucible is subjected to a first temperature rise ranging from -20°C to 100°C, at a heating rate of 10°C/minute, is then cooled from 100°C to -20°C at a cooling rate of 10°C/minute and is finally subjected to a second temperature rise ranging from -20°C to 100°C at a heating rate of 5°C/minute. During the second temperature rise, the variation in the difference in power absorbed by the empty crucible and by the crucible containing the sample of pasty fatty substance is measured as a function of the temperature. The melting point of the pasty fatty substance is the value of the temperature corresponding to the tip of the peak of the curve representing the variation in the difference in power absorbed as a function of the temperature.

The liquid fraction by weight of the pasty fatty substance at 23°C is equal to the ratio of the heat of fusion consumed at 23°C to the heat of fusion of the pasty fatty substance.

The heat of fusion of the pasty fatty substance is the heat consumed by the substance in order to pass from the solid state to the liquid state. The pasty fatty substance is said to be in the solid state when all of its mass is in crystalline solid form. The pasty fatty substance is said to be in the liquid state when all of its mass is in liquid form. The heat of fusion of the pasty fatty substance is equal to the area under the curve of the thermogram obtained using a differential scanning calorimeter (DSC), such as the calorimeter sold under the name MDSC 2920 by the company TA Instrument, with a temperature rise of 5°C or 10°C per minute, according to the standard ISO 1 1357-3; 1999.

The heat of fusion of the pasty fatty substance is the amount of energy required to make the pasty fatty substance change from the solid state to the liquid state. It is expressed in J/g.

The heat of fusion consumed at 23°C is the amount of energy absorbed by the sample to change from the solid state to the state that it has at 23°C, composed of a liquid fraction and a solid fraction.

The liquid fraction of the pasty fatty substance measured at 32°C preferably represents from 30% to 100% by weight of the pasty fatty substance, preferably from 50%> to 100%), more preferably from 60%> to 100% by weight of the pasty fatty substance. When the liquid fraction of the pasty fatty substance measured at 32°C is equal to 100%, the temperature of the end of the melting range of the pasty fatty substance is less than or equal to 32°C.

The liquid fraction of the pasty fatty substance measured at 32°C is equal to the ratio of the heat of fusion consumed at 32°C to the heat of fusion of the pasty fatty substance. The heat of fusion consumed at 32°C is calculated in the same way as the heat of fusion consumed at 23°C.

Advantageously, the content of dyestuff(s) represents from 0.1% to 25% by weight and more specifically from 0.1% to 15% by weight relative to the total weight of the composition. FILLERS

The composition according to the invention may optionally comprise at least one or more filler(s) of organic or mineral nature.

The term "filler" should be understood to mean colourless or white solid particles of any shape which are in a form that is insoluble and dispersed in the medium of the composition. These particles, of mineral or organic nature, can give body or rigidity to the composition and/or softness and uniformity to the makeup. The fillers, in particular organic fillers, are not dyestuffs.

The fillers used in the compositions according to the present invention may be in lamellar, globular or spherical form, in the form of fibres or in any other form intermediate between these defined forms.

The fillers according to the invention may or may not be surface-coated, and in particular they may be surface-treated with silicones, amino acids, fluoro derivatives or any other substance that promotes the dispersion and compatibility of the filler in the composition.

Examples of mineral fillers that may be mentioned include talc, mica, silica, hollow silica microspheres, kaolin, calcium carbonate, magnesium carbonate, hydroxyapatite, boron nitride, glass or ceramic microcapsules, or composites of silica and of titanium dioxide, for instance the TSG series sold by Nippon Sheet Glass.

Examples of organic fillers that may be mentioned include polyamide powder (Nylon ^® Orgasol from Atochem), polyethylene powder, polymethyl methacrylate powder or powders of methyl methacrylate copolymers (for example: Polypore ^® L 200 - polymethyl methacrylate/ethylene glycol dimethacrylate; Chemdal Corporation), polytetrafluoroethylene powders (for example: Teflon), powders of acrylic acid copolymers (Polytrap from the company Dow Corning), lauroyllysine, hollow polymer microspheres such as those of polyvinylidene chloride/acrylonitrile (for example: Expancel from Akzo Nobel), synthetic or natural micronized waxes, metal soaps derived from organic carboxylic acids containing from 8 to 22 carbon atoms and preferably from 12 to 18 carbon atoms, for example zinc stearate, magnesium stearate, lithium stearate, zinc laurate or magnesium myristate, silicone fillers, polyurethane powders, and mixtures of these fillers.

As regards the silicone fillers, they may be chosen more particularly from silicone resin microbeads, polymethylsilsesquioxane powders, and powders of crosslinked elastomeric organopolysiloxane coated with silicone resin, and mixtures thereof.

Organopolysiloxane powders coated with silicone resin, for example coated with silsesquioxane resin, as described especially in patent US 5 538 793, are especially suitable for performing the invention. Such elastomer powders are sold under the names KSP-100, KSP-101, KSP-102, KSP-103, KSP-104 and KSP-105 by the company Shin- Etsu, and have the INCI name: vinyl dimethicone/methicone silsesquioxane crosspolymer. Mention may also be made of powders of crosslinked elastomeric organopolysiloxane coated with silicone resin such as powders of a hybrid silicone functionalized with fluoroalkyl groups, sold in particular under the name KSP-200 by the company Shin-Etsu, or powders of hybrid silicones functionalized with phenyl groups, sold especially under the name KSP-300 by the company Shin-Etsu.

As regards the polymethylsilsesquioxane powders, mention may be made most particularly of silicone resin microbeads, such as those sold under the name Tospearl by the company Momentive Performance Materials, and especially under the reference Tospearl 145 A; and mixtures thereof. As regards the polyurethane powders, mention may be made in particular of powders of crosslinked polyurethane comprising a copolymer, the said copolymer comprising trimethylol hexyl lactone. It may in particular be a hexamethylene diisocyanate/trimethylol hexyl lactone polymer. Such particles are especially commercially available, for example, under the name Plastic Powder D-400 ^® or Plastic Powder D-800 ^® from the company Toshiki, and mixtures thereof.

Preferably, the organic filler is chosen from silicone fillers or mixtures thereof, in particular from powders of crosslinked elastomeric organopolysiloxane coated with silicone resin.

A composition used according to the invention may comprise one or more fillers, advantageously in a content ranging from 0.1% to 15% by weight and in particular from 1% to 10% by weight relative to the total weight of the composition.

In accordance with one variant of the invention, the composition comprises at least one mineral filler, advantageously in a content of between 0.1% to 15% by weight and in particular from 1% to 10% by weight relative to the total weight of the composition. According to another variant, the composition comprises at least one organic filler, advantageously in a content of less than 8% by weight relative to the weight of the composition, and more particularly in a maximum content of 6% by weight relative to the weight of the composition. In accordance with an even more preferential variant, and if the composition comprises any, the content of organic filler is between 0.1% and 6% by weight relative to the weight of the composition.

In accordance with this variant, the composition preferably comprises at least 10% by weight of one or more non-volatile phenyl silicone oils not bearing any dimethicone fragments.

The presence of these fillers makes it possible to further reduce the phenomenon of migration of the composition.

ADDITIVES

The composition according to the invention may furthermore comprise any of the ingredients conventionally used as additives in the cosmetics and dermatology field.

These additives are advantageously chosen from surfactants, antioxidants, thickeners, sweeteners, basifying or acidifying preserving agents, and mixtures thereof, and may be chosen advantageously from those proposed in Table 1 of the Codex Alimentarius.

As antioxidant, a composition in accordance with the invention may advantageously comprise at least one pentaerythrityl di-t-butyl hydroxycinnamate.

A composition according to the invention may also contain flavourings and/or fragrances.

As cosmetic active agents that may be used in the invention, mention may be made of sunscreens, vitamins A, E, C and B3, provitamins such as D-panthenol, calmatives such as a-bisabolol, Aloe vera, allantoin, plant extracts or essential oils, protective or restructuring agents, refreshing agents such as menthol and derivatives thereof, emollients, moisturizers and essential fatty acids, and mixtures thereof.

The amounts of each of these various ingredients, if they are present, are those conventionally used in the fields under consideration, and range, for example, from 0.01% to 10% 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 compound(s), and/or the amount thereof, such that the advantageous properties of the composition according to the invention are not, or are not substantially, adversely affected by the envisaged addition. The example hereinafter is given as a non-limiting illustration of the field of the invention.
