Japanese Patent JP3225967

B2

Compsns. (I) comprise, in a medium acceptable for cosmetic, pharmaceutical and/or hygienic use, a dispersion of particles of at least one polymer surface-stabilised by a stabilising agent in a non-aq. medium, provided that: (a) the non aq. medium is composed of at least one non-aq. liq. chosen from (i) non-aq. liq. compsns. having an overall solubility parameter in the HANSEN interval of solubility of < 17 (MPa)1/2 , and/or (ii) mono-alcohols with an overall solubility parameter in the HANSEN interval of solubility of at most 20 (MPa)1/2; and (b) (i) when the non-aq. medium comprises at least one silicone oil, the stabilising agent is chosen from graft or sequenced block copolymers having at least one polyorganosiloxane unit and at least one radical polymer unit, or a polyether or a polyester; and (ii) when the non-aq. medium contains no silicone oil, the stabilising agent is chosen from (A) graft or sequenced block copolymers having at least one polyorganosiloxane unit and at least one radical polymer unit, or a polyether or a polyester, (B) copolymers of (meth)acrylates of 1-4C alcohols and copolymers of (meth)acrylates of 8-30C alcohols; and (C) graft or sequenced block copolymers having at least one block resulting from the polymerisation of dienes and which is opt. hydrogenated, and at least one block of a vinyl polymer, an acrylic polymer, a polyether and/or a polyester.
