  The invention relates to emulsions comprising two non-aqueous, immiscible liquids, (L1) and (L2), whereby the liquid (L1), which is either the continuous or dispersed phase of the emulsion, is a silicone. The emulsion is further stabilized by at least one graft or block co-polymer of which one fraction is soluble in the dispersed phase the other in the continuous phase, the fraction soluble in the continuous phase being greater than the fraction soluble in the dispersed phase. The invention further relates to dispersions of said emulsions in an aqueous or organic phase and use of said emulsions and dispersions in the field of cosmetic and/or dermatological formulations

  该发明涉及包含两种非水相、不相溶液体（L1）和（L2）的乳液，其中液体（L1）是硅油，它是乳液的连续相或分散相。该乳液进一步通过至少一种嵌段或嵌块共聚物稳定，其中一个部分可溶于分散相，另一个部分可溶于连续相，可溶于连续相的部分大于可溶于分散相的部分。该发明还涉及所述乳液在水相或有机相中的分散体以及所述乳液和分散体在化妆品和/或皮肤科配方领域中的使用。

  公开（公告）日：2004-12-02

  The invention relates to a method for stabilizing an aqueous formulation, comprising up to 40% by weight of one or several surfactants and at least one organic phase chosen from organic or mineral oils/greases/waxes, the products of alchoholysis of said oils/greases/waxes, essential oils, the mono-, di- and tri-glycerides, the fatty acids, the esters of said acids and the alcohols, individually or combined. According to said method, an emulsion is introduced into the aqueous composition, the continuous phase of which is at least one silicone, the dispersed phase is the organic phase as above stabilized by at least one graft or block copolymer, one fraction of which is soluble in the dispersed phase, the other soluble in the continuous phase, whereby the fraction soluble in the continuous phase is greater than the fraction soluble in the dispersed phase.
