Abstract: A cosmetic composition comprises a cosmetic vehicle and from 0.5-10 percent by weight of at least one copolymer having the formula ##STR1## wherein B represents Na, K, NH.sub.4, ##STR2## or 2-amino-2-methyl propanol-1; R.sub.1 and R.sub.2 each independently represent hydrogen or --(X)--OH; X represents alkylene having 1-3 carbon atoms or alkylene substituted by at least one hydroxymethyl; M represents at least one unsaturated monomer selected from acrylamides or methacrylamides substituted on the nitrogen by alkyl, the acrylates or methacrylates of monoalkyl ether of ethylene glycol or of polyethylene glycol, and N-vinylpyrrolidone; x is 22-64 mole percent, y is 13-71 mole percent, z is 6-23 mole percent, v is 0-22 mole percent, and x+y+z+v is equal to 100 mole percent.

Abstract: The present invention has for its object novel copolymers with a base of N-alkyl acrylamide or methacrylamide and their uses in cosmetics particularly in setting lotions and lacquer and in other preparations such as, for example, nail polish.

Abstract: A cosmetic composition comprises a cosmetically acceptable vehicle and at least one copolymer having units of a vinyl, allyl or methally ester of an .alpha.- or .beta.-cyclic carboxylic acid. A process for producing the said copolymer comprises reacting the monomeric constituents of the copolymer at a temperature between 45.degree.-100.degree. C. for a period ranging from 6 to 24 hours.

Abstract: Unsaturated compounds corresponding to the following formula: ##STR1## in which: R' represents a hydrogen atom or a methyl radical are provided as antioxidant monomers from which antioxidant polymers can be prepared.

Abstract: Copolymers having the formula ##STR1## where B represents Na, K, NH.sub.4, ##STR2## or 2-amino-2-methylpropanol-1, R.sub.1 and R.sub.2 represent hydrogen or -(X) OH; X represents an alkylene having 1-3 carbon atoms or alkylene substituted by at least one hydroxy methyl, M represents at least one unsaturated monomer selected from acrylamides or methacrylamides substituted on the nitrogen by alkyl, the acrylates or methacrylates of monoalkyl ether of ethylene glycol or of polyethylene glycol, and N-vinylpyrrolidone, x is 22-64 mole percent, y is 13-71 mole percent, z is 6-23 mole percent, v is 0-22 mole percent and x+y+z+v is equal to 100 mole percent, can be produced by copolymerizing N,N-dimethylamino-2 ethyl methacrylate, methyl methacrylate, methacrylic acid and optionally at least one other monomer corresponding to M.

Abstract: An anti-solar polymer has in the macromolecular chain thereof at least one unit of the formula ##STR1## wherein F is a residue derived from an aromatic compound. The anti-solar polymer can also be one having in the macromolecular chain thereof at least one unit of the formula ##STR2## wherein F.sub.1 is ##STR3## These polymers have the ability to absorb wave lengths of light in the range of about 280-315 millimicrons. The polymers are employed in a cosmetic composition.
