Emulsion comprising an anionic acrylic copolymer and a lipophilic polymer A subject of the present invention is a composition in the form of an emulsion, preferably in the form of an oil-in-water emulsion, comprising at least one hydrophilic gelling polymer chosen from anionic acrylic copolymers and at least one lipophilic polymer comprising at least hydroxyethyl acrylate units and acrylate units bearing a lipophilic group, wherein the weight ratio of the sum of all the hydroxyethyl acrylate units to the sum of all the acrylate units bearing a lipophilic group ranges from 1:30 to 1:1 and wherein the lipophilic polymer has a number-average molecular weight Mn ranging from 2000 to 9000 g/mol. The composition in accordance with the invention makes it possible to obtain emulsions which are homogeneous (the emulsion is macroscopically smooth and has no grains, after storage in a pot for 24 hours at ambient temperature (25° C.)), which have a variable viscosity (very fluid to very thick), which are stable over time, and which have good sensory properties, in particular which are non-tacky, non-shiny and non-greasy on the skin.
