Beschreibung
Zusammenfassung:	A method of preparing an oil-in-water emulsion comprises combining (A) an organopolysiloxane including at least two silicon-bonded hydrolysable or hydroxyl groups and (B) an organic oil to give a mixture. The method further comprises combining the mixture, (C) an aqueous medium and (D) a surfactant to form an initial emulsion. Finally, the method comprises contacting the organopolysiloxane (A) with (D1) an organic acid catalyst to polymerize the organopolysiloxane (A) to give (A1) a high molecular weight organopolysiloxane and the oil-in-water emulsion. A personal care composition comprising the oil-in-water emulsion and a personal care ingredient is also disclosed. 本发明提供了种制备水包油乳液的方法，包括将(A)包含至少两个硅键合的可水解基团或羟基基团的有机聚硅氧烷和(B)有机油混合以产生混合物。所述方法还包括将混合物、(C)水介质和(D)表面活性剂混合以形成初始乳液。最终，所述方法包括使所述有机聚硅氧烷(A)与(D)有机酸催化剂接触以聚合所述有机聚硅氧烷(A)以产生(A)高分子量有机聚硅氧烷和所述水包油乳液。本发明还公开了包含所述水包油乳液和个人护理成分的个人护理组合物。
