粉底液暗沉影响因素研究

Research on the Causes of Foundation Liquid Darkening

摘要: 通过考察产品剂型、配方中油脂的种类和色粉比例对粉底液暗沉的影响，找出规律，以优化后期的配方设计。结果表明，硅油包水剂型粉底液的暗沉出现得较慢；油脂含量、挥发性对粉底液暗沉有较大影响，含量越高，后期暗沉速度越快，程度越大；非挥发性油脂含量越高，后期暗沉速度越慢。色粉的比例对粉底液控油有影响，色粉比例越高暗沉越快。

Abstract: By observing the influence of product dosage form, types of oils in the formulation, and the ratio of pigment powder on the darkening of foundation liquid, patterns were identified to optimize future formulation designs. The results indicate that water-in-silicone oil emulsion foundation liquids exhibit slower darkening; higher oil content and volatility significantly affect the darkening of the foundation liquid, with higher content leading to faster and more severe darkening over time; non-volatile oil content slows down the darkening process. The ratio of pigment powder affects the oil control of the foundation liquid, with a higher ratio leading to faster darkening.
