常用油脂对化妆品保湿效果的影响研究

Study on the Influence of Common Oils to the Moisturizing Function of Cosmetics

化妆品的保湿功能越来越受到关注。利用一种自制的体外模型,通过称重法模拟评测化妆品中一些常用油脂对皮肤内水分的保湿能力。结果发现,当油脂作为化妆品中的一种组分时,在W/O体系中可以显现出与其单一使用时一致的封闭保湿性,而当在O/W体系中时则并没有与其本身的封闭保水性相似的规律。研究所得到的数据可为化妆品配方设计中油脂的选择带来一定的启示。

The moisturizing function of cosmetics has gained much attention in their developmental process. In this study, a self-madein vitro model was used to simulate and evaluate the influence of common oils to the skin moisturizing function of cosmetics by weighing method. The results showed that when oils became a component of cosmetics, the closed moisturizing function of water-in-oil emulsion system was consistent with the pure oil, while there is no consistency between oil-in-water emulsion system and the pure oil. The data obtained in this study could provide some enlightenment for the choice of oils in cosmetic formulation.
