Abstract

Concentrated aqueous dispersion of microgels and cosmetic composition The invention relates to an aqueous dispersion of thermosensitive microgels of poly(oligo-(ethylene glycol)methacrylate) comprising a mass percentage of microgels ranging from 5% to 40%. This dispersion is obtained by partial dehydration of an aqueous dispersion of microgels resulting directly from the polymerization of the precursor monomers. The partial dehydration can be carried out by zeodration. The invention also relates to an aqueous dispersion of microgels optionally comprising a cosmetic active ingredient which is encapsulated in a significant quantity in the microgels, and to a cosmetic composition formulated from this concentrated aqueous dispersion.
