Abstract:
1. A composition comprising an aqueous phase, said aqueous phase comprising at least one electrolyte and at least one crosslinked amphiphilic polymer present in a viscosity stabilizing effective amount, said polymer comprising polymerized units of at least one ethylenically unsaturated monomer comprising a sulphonic group in a free form, a partially neutralized form or a totally neutralized form, and at least one hydrophobic portion, wherein the at least one electrolyte is selected from the group consisting of an alkaline-earth metal salt, a lithium salt, a zinc salt, a manganese salt, an iron salt, a copper salt, a selenium salt, and a mixture thereof, wherein the electrolyte comprises ions chosen from the group consisting of carbonate, bicarbonate, sulphate, phosphate, sulphonate, glycerophosphate, borate, bromide, chloride, nitrate, acetate, hydroxide, persulphate, ions of α-hydroxy acids, ions of fruit acids, ions of β-hydroxy acids, ions of amino acids, and mixtures thereof, and wherein the amount of electrolyte is from 0.01% to 20% by weight relative to the total weight of the composition.
