The cosmetic compositions of the present invention include at least one hydrophilic gelling agent.

This gelling agent may more particularly be chosen from acrylic polymers described as follows: a- Hydrophilic acrylic polymers

According to the invention, the term "hydrophilic acrylic polymers" especially means non- hydrophobic and non-amphiphilic acrylic polymers.

Said hydrophilic acrylic polymers according to the invention are either polyacrylamidomethylpropanesulfonic acid (AMPS^®) acrylic polymers or acrylic acid polymers. The presence of this hydrophilic acrylic polymer makes it possible especially to obtain a composition that has good stability properties.

Among the hydrophilic acrylic polymers that may be mentioned are the following polymers:

Acrylic polymers comprising at least one monomer bearing a sulfonic group.

According to a first embodiment, the hydrophilic acrylic polymer used according to the invention comprises at least one monomer bearing a sulfonic group.

The polymers used in accordance with the invention are homopolymers that may be obtained from at least one ethylenically unsaturated monomer bearing a sulfonic group, which may be in free form or partially or totally neutralized form.

Preferentially, the polymers in accordance with the invention are partially or totally neutralized with a mineral base (sodium hydroxide, potassium hydroxide or aqueous ammonia) or an organic base such as monoethanolamine, diethanolamine, triethanolamine, an aminomethylpropanediol, N-methylglucamine, basic amino acids, for instance arginine and lysine, and mixtures of these compounds. They are generally neutralized.

In the present invention, the term "neutralized" means polymers that are totally or virtually totally neutralized, i.e. at least 90% neutralized. The polymers used in the composition of the invention generally have a number-average molecular weight ranging from 1000 to 20 000 000 g/mol, preferably ranging from 20 000 to 5 000 000 g/mol and even more preferentially from 100 000 to 1 500 000 g/mol.

These polymers according to the invention may be crosslinked or noncrosslinked. The monomers bearing a sulfonic group of the polymer used in the composition of the invention are especially chosen from vinylsulfonic acid, styrenesulfonic acid, (meth)acrylamido(Cr C₂₂)alkylsulfonic acids, N-(C₁-C₂2)alkyl(meth)acrylamido(C₁-C₂2)alkylsulfonic acids such as undecylacrylamidomethanesulfonic acid, and also partially or totally neutralized forms thereof, and mixtures thereof.

More particularly, 2-acrylamido-2-methylpropanesulfonic acid (AMPS^®), and also partially or totally neutralized forms thereof, is used.

When the polymers are crosslinked, the crosslinking agents may be chosen from the polyolefinically unsaturated compounds commonly used for crosslinking polymers obtained by free-radical polymerization.

Examples of crosslinking agents that may be mentioned include divinylbenzene, diallyl ether, dipropylene glycol diallyl ether, polyglycol diallyl ethers, triethylene glycol divinyl ether, hydroquinone diallyl ether, ethylene glycol or tetraethylene glycol di(meth)acrylate, trimethylolpropane triacrylate, methylenebisacrylamide, methylenebismethacrylamide, triallylamine, triallyl cyanurate, diallyl maleate, tetraallylethylenediamine, tetraallyloxyethane, trimethylolpropane diallyl ether, allyl (meth)acrylate, allylic ethers of alcohols of the sugar series, or other allylic or vinyl ethers of polyfunctional alcohols, and also the allylic esters of phosphoric and/or vinylphosphonic acid derivatives, or mixtures of these compounds. According to one preferred embodiment of the invention, the crosslinking agent is chosen from methylenebisacrylamide, allyl methacrylate and trimethylolpropane triacrylate (TMPTA). The degree of crosslinking generally ranges from 0.01 mol% to 10 mol% and more particularly from 0.2 mol% to 2 mol% relative to the polymer. The homopolymer of monomers bearing a sulfonic group may be crosslinked with one or more crosslinking agents.

These homopolymers are generally crosslinked and neutralized, and they may be obtained according to the preparation process comprising the following steps:

(a) the monomer such as 2-acrylamido-2-methylpropanesulfonic acid in free form is dispersed or dissolved in a solution of tert-butanol or of water and tert-butanol;

(b) the monomer solution or dispersion obtained in (a) is neutralized with one or more mineral or organic bases, preferably aqueous ammonia NH₃, in the amount making it possible to obtain a degree of neutralization of the sulfonic acid functions of the polymer ranging from 90% to 100%;

(c) the crosslinking monomer(s) are added to the solution or dispersion obtained in (b); (d) a standard free-radical polymerization is performed in the presence of free-radical initiators at a temperature ranging from 10 to 150°C; the polymer precipitates in the tert-butanol-based solution or dispersion.

The preferred AMPS^® homopolymers are generally characterized in that they comprise, randomly distributed: a) from 90% to 99.9% by weight of units of general formula (II) below:

CH₃ in which X⁺ denotes a proton, an alkali metal cation, an alkaline-earth metal cation or the ammonium ion, not more than 10 mol% of the cations X⁺ possibly being protons H⁺; b) from 0.01 % to 10% by weight of crosslinking units derived from at least one monomer containing at least two olefinic double bonds; the weight proportions being defined relative to the total weight of the polymer.

The homopolymers according to the invention that are more particularly preferred comprise from 98% to 99.5% by weight of units of formula (II) and from 0.2% to 2% by weight of crosslinking units.

A polymer of this type that may especially be mentioned is the crosslinked and neutralized 2- acrylamido-2-methylpropanesulfonic acid homopolymer sold by the company Clariant under the trade name Hostacerin^® AMPS (CTFA name: ammonium polyacryldimethyltauramide). Acrylamide/AMPS^® copolymers

According to another embodiment, the hydrophilic acrylic polymer is a crosslinked anionic copolymer formed from units derived from the reaction between (i) acrylamide (monomer 1 ), (ii) 2-acrylamido-2-methylpropanesulfonic acid (monomer 2, referred to hereinbelow for convenience as AMPS^®) and (iii) at least one polyolefinically unsaturated compound (monomer 3), constituting here the crosslinking agent.

The crosslinked anionic copolymers used in the context of the present invention are products that are already known per se and their preparation has been described especially in patent application EP-A-0 503 853, the content of which is consequently included in its entirety by reference in the present description.

The polyolefinically unsaturated monomers used as crosslinking agents for the preparation of the copolymers in accordance with the invention are preferably chosen from the group formed by methylenebisacrylamide, allyl sucrose and pentaerythritol. Even more preferentially, use is made of methylenebisacrylamide.

Preferably, said polyolefinically unsaturated compound is present in the copolymer in a concentration of between 0.06 and 1 mmol per mole of the monomer units as a whole.

The ratio, expressed in mol%, between acrylamide and AMPS^® is preferentially between 85/15 and 15/85, advantageously between 70/30 and 30/70, even more preferentially between 65/35 and 35/65 and even more particularly between 60/40 and 40/60. In addition, AMPS is generally at least partially neutralized in the form of a salt, for example with sodium hydroxide, with potassium hydroxide or with a low molecular weight amine such as triethanolamine, or mixtures thereof. A crosslinked copolymer that is particularly preferred in the context of the implementation of the present invention corresponds to the one prepared in Example 1 of patent application EP-A-0 503 853 mentioned above, and which is then in the form of a water-in-oil inverse emulsion. More precisely, this copolymer is formed from 60 mol% of acrylamide and 40 mol% of the sodium salt of AMPS^®, and it is crosslinked with methylenebisacrylamide in a proportion of 0.22 mmol per mole of the total monomer mixture. The final water-in-oil inverse emulsion preferably contains about 40% by weight of crosslinked copolymer as defined above and about 4% by weight of an ethoxylated fatty alcohol with an HLB of about 12.5.

The composition in accordance with the invention may comprise from 0 to 50% by weight, for example from 1 to 20% by weight, for example from 2 to 10% by weight, of sunscreen agent relative to the total weight of the composition.

UV booster

The composition of the present invention may further comprises one or more UV booster.

"UV booster" means each organic or inorganic, non polymeric or polymeric compound able to increase the Sun Protection Factor and/or the PPD Index (UVA protection index) of a UV sunscreening composition containing at least one UVA and/or UVB screening agent.

The efficacy of antisun compositions is generally expressed by the sun protection factor (SPF), which is expressed mathematically by the ratio of the dose of UV radiation necessary to reach the erythemogenic threshold with the UV screening agent to the dose of UV radiation necessary to reach the erythemogenic threshold without UV screening agent. This factor thus relates to the effectiveness of the protection with respect to erythema, the spectrum of biological action of which is centred in the UV-B region, and consequently describes the protection with respect to this UV-B radiation.

In view of the effects of UV-A radiation on the skin and of the development of numerous compositions comprising combinations of screening agents capable of absorbing UV-B and/or UV-A radiation, specific methods for evaluating protection against UV-A radiation have been developed. For the characterization of protection with respect to UV-A radiation, the PPD (Persistent Pigment Darkening) method, which measures the colour of the skin observed 2 to 4 hours after exposure of the skin to UV-A radiation, is particularly recommended and used. This method was adopted in 1996 by the Japanese Cosmetic Industry Association (JCIA) as official test procedure for the UV-A labelling of products and is frequently used by test laboratories in Europe and the United States (Japan Cosmetic Industry Association Technical Bulletin. Measurement Standards for UVA protection efficacy. Issued November 21 , 1995 and effective of January 1 , 1996).

The sun protection factor UV-APPD (UV-APPD PF) is expressed mathematically by the ratio of the dose of UV-A radiation necessary to reach the pigmentation threshold with the UV screening agent (MPPDp) to the dose of UV-A radiation necessary to reach the pigmentation threshold without UV screening agent (MPPDnp).

UV-App_D PF =MPPD_p/MPPD_np

Mentions may be made of the UV booster such as styrene/acrylates copolymer that are marketed, for example under the tradename Sunspheres^™ Powder by the company Rohm and Haas (Dow Chemical).

The mass of oil remaining in the crystallizing dish is measured at regular intervals. The evaporation rates are expressed in mg of oil evaporated per unit of area (cm2) and per unit of time (minutes). The term "volatile oil" means any non-aqueous medium that is capable of evaporating on contact with the skin or the lips in less than one hour, at room temperature and atmospheric pressure. The volatile oil is a cosmetic volatile oil, which is liquid at room temperature. More specifically, a volatile oil has an evaporation rate of between 0.01 and 200 mg/cm2/min, limits included.
