摘要：
Composition in the form of a self-reversible inverse latex, comprising, for 100% of its mass: a) - From 50% mass to 70% mass of a crosslinked anionic polyelectrolyte (P), obtained by polymerization: - At least a neutral monomer of formula (I): ** Formula ** in which the radical R1 represents a linear or branched aliphatic radical, containing from 8 to 20 carbon atoms and n represents a number greater than or equal to one and less than or equal to thirty； - From at least one neutral monomer selected from acrylamide, N, N-dimethyl acrylamide, N- [2-hydroxy-1,1-bis (hydroxymethyl) ethyl] propenamide [or tris (hydroxymethyl) acrylamidomethane or N- [tris (hydroxymethyl) ) methyl] acrylamide also called THAM] or (2-hydroxyethyl acrylate)； and - Of at least one monomer containing a strong acidic function and / or at least one monomer containing a weak acidic function； b) - From 4% mass to 10% mass of an emulsifying system (S1) of the water-in-oil type (Ag / Ac)； c) - From 1% mass to 10% mass of an emulsifying system (S2) of the oil-in-water type (Ac / Ag) comprising a non-zero mass proportion of a surfactant composition (C), said surfactant composition (C) comprising , for 100% molar: 1) - A proportion greater than or equal to 10% molar and less than or equal to 50% molar of a composition (IIC) comprising, for 100% molar: α) - From 60% molar to 100% molar of a compound of formula (II): ** Formula ** in which: - R2 represents a linear or branched alkyl radical, containing 12 carbon atoms, - T1 represents a hydrogen atom or a radical (-CH2- CH2-O-) m1-H in which m1 is an integer greater than or equal to zero and less than or equal to ten, - T2 equal to or different from T1, represents a hydrogen atom or a radical (-CH2-CH2- O-) m2-H in which m2 is an integer greater than or equal to zero and less than or equal to ten, and - T3 equal to or different from T1 and T2, represents a hydrogen atom or a radical (-CH2- C H2-O-) m3-H in which m3 is an integer greater than or equal to
