Abstract:
1. A cosmetic or pharmaceutical composition comprising, in a physiologically acceptable medium, at least one linear ethylenic block copolymer comprising at least one first block, and at least one second block, each block of the copolymer formed from at least one ionic hydrophilic monomer and at least one additional monomer, the ionic hydrophilic monomer being the same or different from one block to another, the ionic hydrophilic monomer being present in each block in an amount ranging from 2% to 100% by weight relative to the weight of the block copolymer, wherein the additional monomer is chosen from nonionic hydrophilic monomers, hydrophobic monomers, and mixtures thereof, and is selected from the group consisting of: (i) ethylenic hydrocarbons containing 2 to 10 carbons; (ii) (meth)acrylates of formula: wherein R linear and branched alkyl groups of 1 to 30 carbon atoms, optionally intercalated with at least one hetero atom chosen from O, N, S and P; the alkyl groups optionally substituted with at least one substituent chosen from OH, halogen atoms chosen from Cl, Br, I and F, and groups chosen from: —Si(R C C C 4- to 12-membered aromatic and non-aromatic heterocyclic groups containing at least one hetero atom chosen from O, N and S, heterocycloalkyl group having a C wherein the cycloalkyl, aryl, aralkyl, heterocyclic and heterocycloalkyl groups are optionally substituted with at least one substituent chosen from hydroxyl groups, halogen atoms, and linear and branched C —(OC (iii) (meth)acrylamides of formula: wherein R and R hydrogen atoms; and linear and branched alkyl groups of 1 to 30 carbon atoms optionally intercalated with at least one hetero atom chosen from O, N, S and P; the alkyl groups optionally substituted with at least one substituent chosen from —OH, halogen atoms chosen from Cl, Br, I and F, and —Si(R C C C 4- to 12-membered aromatic and non-aromatic heterocyclic groups containing at least one hetero atom chosen from O, N and S, heterocycloalkyl group having a C wherein the cycloalkyl, aryl, aralkyl, heterocyclic and heterocycloalkyl groups are optionally substituted with at least one substituent chosen from hydroxyl groups, halogen atoms, and linear and branched C —(OC (iv) vinyl compounds of formula: CH wherein R linear and branched alkyl groups containing 1 to 30 carbon atoms optionally intercalated with at least one hetero atom chosen from O, N, S and P; the alkyl group optionally substituted with at least one substituent chosen from —OH, halogen atoms chosen from Cl, Br, I and F, and —Si(R C C C 4- to 12-membered aromatic and non-aromatic heterocyclic groups containing at least one hetero atom chosen from O, N and S; heterocycloalkyl group having a C wherein the cycloalkyl, aryl, aralkyl, heterocyclic and heterocycloalkyl groups are optionally substituted with at least one substituent chosen from hydroxyl groups, halogen atoms, and linear and branched C (v) allylic compounds of formula: CH wherein R (vi) silicone-based (meth)acrylic, (meth)acrylamide and vinyl monomers.
