Dispersion of particles of at least one polymer stabilized with a stabilizer in a nonaqueous medium containing at least one hydrocarbon-based oil, the polymer of the particles being a polymer of C 1 -C 4 alkyl (meth)acrylate and optionally of a silicone macromonomer: in which: - R8 denotes a hydrogen atom or a methyl group; preferably methyl; - R9 denotes a linear or branched, preferably linear, divalent hydrocarbon-based group containing from 1 to 10 carbon atoms, preferably containing from 2 to 4 carbon atoms, and optionally containing one or two -O- ether bonds; preferably an ethylene, propylene or butylene group; - R10 denotes a linear or branched alkyl group containing from 1 to 10 carbon atoms, especially from 2 to 8 carbon atoms; preferably methyl, ethyl, propyl, butyl or pentyl; - n denotes an integer ranging from 1 to 300, preferably ranging from 3 to 200 and preferentially ranging from 5 to 100; the stabilizer being a polymer comprising from 50% to 100% by weight, relative to the total weight of the stabilizer, of C 8 -C 22 alkyl acrylate, from 0 to 50% by weight of C 1 -C 4 alkyl (meth) acrylate and optionally silicone macromonomer: the stabilizer and/or the polymer of the particles comprising at least the silicone macromonomer, and: (i) when the stabilizer comprises the silicone macromonomer, the macromonomer is present in the stabilizer in a content of less than or equal to 5.5% by weight, relative to the total weight of the combination of stabilizer + polymer of the particles; the polymer of the particles optionally comprising said silicone macromonomer in a content of less than or equal to 28% by weight, relative to the total weight of the combination of stabilizer + polymer of the particles; (ii) when the polymer of the particles comprises the silicone macromonomer and the stabilizer does not comprise silicone macromonomer, the macromonomer is present in a content of less than or equal to 18% by weight, relative to the total weight of the combination of stabilizer + polymer of the particles. - R8 denotes a hydrogen atom or a methyl group; preferably methyl; - R9 denotes a linear or branched, preferably linear, divalent hydrocarbon-based group containing from 1 to 10 carbon atoms, preferably containing from 2 to 4 carbon atoms, and optionally containing one or two -O- ether bonds; preferably an ethylene, propylene or butylene group; - R10 denotes a linear or branched alkyl group containing from 1 to 10 carbon atoms, especially from 2 to 8 carbon atoms; preferably methyl, ethyl, propyl, butyl or pentyl; - n denotes an integer ranging from 1 to 300, preferably ranging from 3 to 200 and preferentially ranging from 5 to 100; (i) when the stabilizer comprises the silicone macromonomer, the macromonomer is present in the stabilizer in a content of less than or equal to 5.5% by weight, relative to the total weight of the combination of stabilizer + polymer of the particles; the polymer of the particles optionally comprising said silicone macromonomer in a content of less than or equal to 28% by weight, relative to the total weight of the combination of stabilizer + polymer of the particles; (ii) when the polymer of the particles comprises the silicone macromonomer and the stabilizer does not comprise silicone macromonomer, the macromonomer is present in a content of less than or equal to 18% by weight, relative to the total weight of the combination of stabilizer + polymer of the particles.
