A subject of the invention is also a cosmetic treatment process for keratin materials, which consists in applying to the keratin materials a composition as defined above, and also the use of this composition in the cosmetic or dermatological field, and in particular for caring for, protecting and/or making up bodily or facial skin, or for haircare. The composition according to the invention has both a matt appearance throughout all the steps of its use, from the appearance of the product up to the finished skin, and a comfortable sensation throughout its use, from the application to the total penetration of the product.

A skin care composition having from about 0.01% to about 5%, by weight, of an superabsorbent polymer which is a sodium polyacrylate, sodium polacrylate starch, sodium acrylates crosspolymer-2 or mixtures of these and a portion of the polymer comprises a grafted starch material. The superabsorbent polymer is particulate where the particles have an average particle size in the range of from about 5-30, and the individual particles in their dry or un-swollen condition are substantially non-spherical, flat, platelet, or elongated in shape. The particles have an absorption capacity of at least about 1000 times their initial dry or un-swollen volume. Additionally, the skin care composition contains from about 0.01-10% of a dry powder that is either starch or silicone based and wherein the dry powder is coated with a silicone based material. Further there is provided a UV active.

Provided are ingestible polymeric formulations for the reduction of gastric volume in the treatment of overweight patients, and methods of use thereof. One method involves ingesting one or more ingestible tablets comprising cross-linked polymers formed in a packed mass within the one or more ingestible tablets into a stomach of the subject, wherein the cross-linked polymers comprise a polymer hydrogel comprising carboxymethylcellulose and a carboxylic acid; disintegrating an acid-sensitive gelatin coating such that the coating disintegrates in the gastric fluid and the cross-linked polymers disperse in the stomach; and maintaining the reduction in gastric volume such that a sensation of fullness is induced in the subject without releasing a drug which induces the sensation.

The invention relates to a method for preparing a composition containing hyaluronic acid and/or a salt of hyaluronic acid, as well as at least one biologically active molecule. The method comprises the steps of providing a solution that contains hyaluronic acid and/or a salt of hyaluronic acid, adding an alkaline solution, adding the at least one biologically active molecule, and adding an acid solution to obtain the composition. The invention additionally comprises a composition prepared by the method according to the invention and a use of the stated composition for aesthetic and/or therapeutic use in humans and/or animals.

The present invention relates to a method for making a direct emulsion of a copolymer in water, characterized in that it comprises the polymerization of at least, expressed as a percentage by weight of each of the monomers based upon the total weight of the monomers: a) 10 to 80% by weight of methacrylic acid and, optionally, of acrylic acid; b)15 to 80% by weight of at least one non-ionic vinyl monomer; c) 0.05 to 9.5% by weight of 2-acrylamido-2-methylpropane sulfonic acid or a salt thereof; d) 0.5 to 30% by weight of at least one monomer containing at least one hydrophobic group; and e) 0.01 to 5% by weight of at least one crosslinking monomer; said polymerization being carried out in the presence of at least one surfactant. It also relates to the corresponding new copolymer emulsion in water, a method for thickening an aqueous composition comprising such an emulsion of copolymer and to an aqueous composition comprising such a copolymer emulsion.

Process for thickening a composition, through the use of a direct emulsion in water, which is alkali-swellable, of a polymer of the ASE or HASE type, which is both rich in acrylic acid and which has a certain quantity of AMPS. The use of such emulsions simultaneously allows there to be no obligation to use surfactants and organic solvents other than water, and allows the thickening phenomenon to be activated for pHs of less than 7: this latter characteristic is particularly advantageous for formulations intended to he used in contact with skin.
