USE OF HYPERBRANCHED POLYMERS AND DENDRIMERS COMPRISING A PARTICULAR GROUP AS FILM-FORMING AGENT, FILM-FORMING COMPOSITIONS COMPRISING SAME AND USE PARTICULARLY IN COSMETICS AND PHARMACEUTICS

摘要

The invention concerns the use of hyperbranched polymers and dendrimers, comprising at least one group of formula (I) in which: Y represents the oxygen atom or a NH group; and A represents a C1-C12 alkane di-yl group, linear, branched or cyclic, saturated or unsaturated; said group being optionally interrupted by one or several heteroatoms and/or substituted by a function selected among: amino (-NH2): acylamino (-NH-CO-R) in which R represents a C1-C10 alkyl group, linear, branched or cyclic, saturated or unsaturated; carboxylic acid (-COOH), ester (-COOR) in which R represents a C1-C10 alkyl group, linear, branched or cyclic, saturated or unsaturated, as film-forming agent. The invention also concerns a film-forming composition comprising said compound and its use particularly in cosmetics or pharmaceutics.
