use of hyperverzweigten polymers or dendrimeren with special groups as filmbildendes resourcesthis means filmbildende containing compositions and their use in cosmetics or in the pharmacy

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.
