The present invention relates to an oil-in-water microemulsion, which comprises, on the basis of its total weight, the following components of A) 55-95 wt% of a water phase; B) 0.1-20 wt% of an oil phase, wherein the oil phase comprises at least one oil/fat component containing polyoxypropylene chains; and C) 1-25 wt% of an oil-in-water nonionic emulsifier, wherein the emulsifier is selected from the following group of: hydrophilic nonionic surfactants with polyoxyethylene chains as hydrophilic groups, polyglycerol fatty acid esters, polyglycerol fatty alcohol ethers, sucrose fatty acid esters, and hydrocarbyl polyglycosides. The oil-in-water microemulsion of the present invention carries a large amount of oil; when it is used as a rinse-off product, it would remove the colour makeup very rapidly, and it has a easy-to-wash cleansing effect; and when it is used as a leave-on product, it would provide a moisturizing feel and good skin feel different from ordinary aqueous products due to a relatively small amount of the emulsifier used. In addition, the present invention also relates to the use of an oil/fat containing polyoxypropylene chains in increasing the amount of oil carried in an oil-in-water microemulsion.
本发明涉及一种水包油型微乳液,按其总重量计算,包括以下组分 A) 55-95 wt% 的水相;B) 0.1-20 wt% 的油相,其中油相包括至少一种含有聚氧丙烯链的油/脂组分;以及 C) 1-25 wt% 的水包油型非离子乳化剂,其中乳化剂选自以下组别:以聚氧乙烯链为亲水基团的亲水性非离子表面活性剂、聚甘油脂肪酸酯、聚甘油脂肪醇醚、蔗糖脂肪酸酯和烃基聚糖苷。本发明的水包油型微乳液含有大量油脂,用作冲洗产品时,可以快速去除彩妆,具有易洗的清洁效果;用作免洗产品时,由于乳化剂用量较少,可以提供不同于普通水性产品的滋润感和良好的肤感。此外,本发明还涉及使用含聚氧丙烯链的油脂来增加水包油型微乳液中的含油量。
