Claims62
A composition in an aqueous medium, comprising the combination of:
- at least one amphiphilic polymer including at least one fatty chain and at least one hydrophilic unit, wherein said at least one amphiphilic polymer is selected from cellulose ethers possessing hydrophobic substituents, quatemized cationic celluloses modified with groups including at least one fatty chain, quatemized alkylhydroxyethyl celluloses, galactomannans possessing hydrophobic substituents, pullulans modified with hydrophobic groups, gelatins modified with hydrophobic groups, mucopolysaccharides, associative polyurethanes, anionic acrylic polymers containing hydrophobic groups, acrylic acid copolymers with N-alkylacrylamides, methacrylic acid copolymers with N-alkylacrylamides, copolymers between a monomer containing a carboxylic acid group and (meth)acrylate esters, copolymers between a monomer containing a carboxylic acid group and amides bearing cycloaliphatic or aromatic hydrophobic groups, copolymers with perfluoro monomers, copolymers of a monomer bearing a sulphonic acid group and an alkyl (meth)acrylamide possessing at least 8 carbons, nonionic acrylic copolymers containing hydrophobic groups, copolymers of maleic anhydride and monomers containing at least one fatty chain, copolymers of crotonic acid and monomers containing at least one fatty chain, polymers of (meth)acrylic acid modified with groups containing at least one fatty chain, and copolymers of (meth)acrylic acid and monomers containing at least one fatty chain,
- at least one protein including at least one hydrophobic group, wherein said at least one protein is selected from globular proteins, fibrous proteins, proteins with an unordered structure, denatured proteins, and synthetic polypeptides having hydrophobic sequences,
- wherein said at least one amphiphilic polymer and said at least one protein together are present in concentration ranging from 0.8 to 3% by weight relative to the total weight of said composition, and
- wherein said at least one protein is present in a concentration ranging from 0.005% to 2% by weight, relative to the total weight of said composition, and
- a surfactant in an amount less than 5% by weight relative to the total weight of said compositions,
- wherein said composition has a viscosity ranging from 200 to 30,000 cp (mPa·s).
