Abstract
(EN) The invention relates to the field involved in the production of aqueous compositions comprising rheology modifying agents, in particular the production of aqueous detergent or cosmetic compositions having improved, thickening and clarity properties, as well as good suspension properties. In particular, the invention relates to a rheology modifying agent which is a copolymer obtained by means of polymerisation of at least one crosslinking monomer with at least one anionic monomer comprising at least one polymerisable ethylenic unsaturation and at least one hydrophobic non-ionic monomer comprising at least one polymerisable ethylenic unsaturation.
