Description

COMPOSITIONS FOR TOPICAL USE IN THE FORM OF EMULSION OF OIL-IN-WATER WITHOUT SURELY AGENT CONTAINING A POLYACACIDE 2-ACRILAMIDO 2-MET? LPROPANO SULFONICO) RE-TICULATED AND NEUTRALIZED. DESCRIPTION OF THE INVENTION The present application relates to a cosmetic and / or dermatological composition in the form of an oil-in-water emulsion without surfactant containing at least one poly (2-acrylamido-2-methylpropane sulfonic acid) crosslinked and neutralized in at least one 90% For various reasons related in particular - with a better comfort of use (softness, softening and others), the present cosmetic or dermatological compositions most often occur in the form of an oil-in-water emulsion (i.e. support consisting of a continuous aqueous dispersing phase and an oily dispersed discontinuous phase) or an emulsion -of the water-in-oil type (ie a support consisting of a continuous fat dispersing phase and an aqueous dispersed discontinuous phase). Oil-in-water emulsions are the most sought after in the field of cosmetics due to the fact that they provide a smoother, less oily and lighter touch on the skin in the application than water-emulsion systems. ^ -oil. The emulsions are generally stabilized by emulsifying surfactants of the oil-in- - REF: 24953 water type or the water-deceptive type which thanks to their amphiphilic structure are placed on the intermediate surface of oil / water and thus stabilize the scattered qotitas. These amphiphilic molecules, however, have the disadvantage of being penetrating and irritating to the skin, the eyes and the scalp. On the other hand, its presence at high concentrations leads to anti-cosmetics effects such as rough touch, adhesive or sticky touches. Emulsion formulators constantly seek to reduce the content of surfactants with * • > In order to improve its innocuousness with respect to the skin, o-jos and scalp and improve its cosmetic properties. The main difficulty with which they usually face is the obtaining of stable emulsions. The object of the invention is to be able to make stable oil-in-water emulsions which do not contain emulsifying surfactant and which have good eosmetic properties. It is known in the state of the art polymers * • poly (2-acrylamido-2-methyl-methoxysulfonic acid) as -the commercial products COSMEDIA HSP1160 of the HOECHST Company and RHEOTIK 8011 of the HENKEL Company. Thickeners and / or gelling agents are used in numerous cosmetic formulations. These polymers do not allow to stabilize oil-in-water emulsions that do not contain surfactant. The applicant company has discovered inescapably a new family of poly (2-acrylamido 2-methylpropane sulphonic acid polymers that allow to make stable oil-in-water emulsions that do not contain surfactant. These polymers also make it possible to prepare emulsions of oil-in-water, in a wide range of pH, whose viscosity remains stable with time at room temperature or at higher temperatures. They also allow to make homogeneous products, non-adhesive, non-flowing, soft and slippery in the application and stable in The present invention relates to a cosmetic and / or dermatological composition in the form of an oil-in-water emulsion, characterized in that it contains at least one poly (2-acrylamido) acid. * "Methylrpropane sulfonic acid" cross-linked and neutralized by at least 90% and not containing emulsifying surfactant Polymers (2-acrylate acid) 2- ^ r aetilpro pa or sulphonic) re-traceable and practically or completely neutralized, according to the invention, they are hydrosolubles or swellable in water. They are generally characterized by the fact that they comprise randomly distributed a) from 90 to 99.9% by weight of units of the general formula wherein X designates a cation or a mixture of cations, a maximum of 10 mol% of the cations X being protons H; b) from 0.01 to 10% by weight of reticulant units from at least one monomer having at least two olefinic double bonds; the proportions by weight being defined in relation to the total weight of the polymer. Preferably, the polymers of the invention include a number of motifs of formula (1) in a sufficiently high amount to obtain polymer particles whose hydrodynamic volume in water solution has a radius ranging between 10 and 500 nm and whose distribution is homogeneous and unimodal. The more particularly preferred polymers according to the invention comprise from 98 to 99.5% by weight of units of formula (1) and from 0.2 to 2% by weight of crosslinking units, represents a cation or a mixture of cations selected in particular between a proton, an alkali metal cation, an equivalent cation of an alkaline earth metal or in ammonium. More particularly, from 90 to 100 mol% of the cations are NH cations. and from 0 to 10 mol% are proto- nes (H +). • The crosslinking monomers that have two olefinic double bonds are selected for example between dipropylene glycol-dialyl ether, polyglycol diallyl ether, triethylene glycol, divinylether, hydroquinone-diallyl ether, tetralil -oxietanoyl or other allyl or vinyl ethers polyfunctional alcohols, tetraethylene glycol diarylate, triallylane, trlmethylolpropane diallyl ether, methylene-bis-acrylamide or divinylbenzene, crosslinking monomers having at least two olefinic double bonds are more particularly between those that respond to the general formula (2) if next? wherein R, designates a hydrogen atom or an alkyl of C, -C4 and more particularly methyl (trimethylol propane triacrylate). The polymerization reaction of the polymers of the invention produces not only linear chains but < • * • also branched or cross-linked polymer molecules. These molecules can be characterized particularly by their rheological behavior in water but more particularly by the diffusion of the dynamic light. In the case of the characterization of the molecules by the diffusion of the dynamic light, the distribution of the hydrodynamic volume of the polymer structures is measured. The macromolecules dissolved in water are flexible and surrounded by a solvation shell formed by water molecules. With charged polymers like those of the invention, the size of the molecules depends on the amount of salt in the water. In pooled solvents, the uniform charge along the polymer backbone leads to a significant expansion of the polymer chain. The fact of increasing the amount of salt increases the amount of electrolyte in the solvent and overloads the uniform charges of the polymer. In addition to the molecules transported in the solar envelope, the solvent molecules are fixed in the cavities of the polymer. In this case, di solvent molecules are part of the macromolecules in solution and move at the same average speed. Thus, the hydrodynamic volume describes the linear dimension of the macromolecule and these solvation molecules. The hydrodynamic volume V. was determined by the following formula: with: M which designates the mass in grams of the undissolved acromolecule; N that designates Avogadro's number; V. which designates the specific volume of the solvent; V- that designates the specific volume of the macromolédula; d the mass in grams of the solvent that is associated with 1 gram of non-dissolved macromolecule. If the hydrodynamic particle is spherical, then it is easy to calculate from the hydrodynamic volume. the hydrodynamic radius by the formula: h = r. 3/3 with R that designates the dynamic radius. The cases where the hydrodynamic particles are perfect spheres are extremely rare, The majority of the synthetic polymers involve compact structures or ellipsoids of high eccentricity. In this case, the determination of the radius is made on a sphere - which is equivalent from a friction point of view in the form of the particle considered. By general normal, one operates on distributions of molecular weight and consequently on distributions of radio and hydrodynamic volume. For the polydispersed systems, the distribution of the diffusion coefficients must be calculated. From this distribution, the results regarding the radial distribution and the distribution of the hydrodynamic volumes are deduced. The hydrodynamic volumes of the polymers of the invention are in particular determined by diffusion of the dynamic light from the D-diffusion coefficients according to STOKES-EINSTEIN of the formula: D = where k is the Bóltzmann constant, T temperature ab solute in degrees Kelvin, h is the viscosity of the solvent (water) and R is the hydrodynamic radius. These diffusion coefficients D are measured according to "-the method of characterization of a polymer mixture by diffusion with LASER described in the following references s (1) Pécora, R; Dynamis Light Ssattering; fleniura Press, New York, 1976; (2) Chu, B; Dynamic Light Scattering; Asademic Press, New York, 1994; (3) Schmitz, KS; Introduction to Dynamic Light Scattering; Academic Press, New York, 1990; (4) Provincher S.; Comp.
