Abstract
The invention concerns an aqueous composition comprising particles of a water-soluble or water-dispersible chemical microgel, associated with at least a water-soluble or water-dispersible crosslinking polymer, differing in composition from the particles; the amount of chemical microgel particles ranging between 0.05 to 40% by dry weight of the composition and the amount of crosslinking polymer being such that the viscosity of the composition is at least three times higher than that of an aqueous solution of chemical microgel particles and than that of an aqueous solution of crosslinking polymer, in similar conditions. The invention also concerns said composition, its use and formulations comprising same.
