The present invention concerns a composition comprising: (i) one or a plurality of acrylic copolymers comprising, in terms of monomers: (a) at least one unsaturated acid monomer chosen from the acrylic or methacrylic acids or the salts thereof (b) at least one unsaturated acrylate or methacrylate ester monomer having, in the structure of same, at least one linear or branched fatty-chain alkyl group, preferably having a C8-C30 alkyl group, more preferably a C10-C15 alkyl group, and more preferably still a C12-C13 alkyl group (c) at least one unsaturated acrylate or methacrylate ester monomer having, in the structure of same, at least one linear or branched short-chain alkyl group, preferably branched, preferably having a C2-C6 alkyl group, more preferably a C3-C5 alkyl group, and more preferably still a C4 alkyl group and (d) at least one acrylamide monomer having a linear or branched alkyl group, preferably branched, preferably having a C3-C10 alkyl group, preferably a C4-C8 alkyl group (ii) one or more thickening polymer(s), the weight ratio between the total quantity of the acrylic copolymer(s) and the total quantity of the thickening polymer(s) being greater than or equal to 6.0.
