采用体外测试和人体测试相结合的方法对底妆产品进行相应的功效评价研究.体外测试方法是通过计算在标准黑白卡纸、人造皮革、人工汗液等辅助材料中使用产品前后的对比率(CR值)、ITA°、色差∆E值评估底妆产品的遮盖力、白度、防水抗汗效果;人体测试方法是通过受试者前臂皮肤经过沾试/浸水/喷汗等处理前后的色差∆E值变化来评估底妆产品的抗沾性以及防水/抗汗效果.体外测试结果显示,标准黑白卡纸上不同品类样品的CR值之间有显著性差异(P<0.05),人造皮革的ITA°与使用前比较有显著性上升(P<0.05),沾试后的黑布色差∆E值大于1.5,经过清水、人工汗液处理前后的皮革色差∆E值小于1.5;人体临床测试结果显示,沾试前后的人体皮肤色差∆E值无显著性差异(P>0.05),人体皮肤的色差∆E值变化率小于50%;体外的测试结果与视觉评估、人体测试结果保持基本一致.结果表明,底妆产品的体外和人体评价方法直观、可量化,可用于底妆产品妆效评价.
Research on the in vitro and clinical efficacy evaluation methods for foundation products
The study aimed to establish a combination of in vitro and clinical efficacy evaluation methods for foundation products.The coverage,whiteness,waterproof and sweat resistance effects were evaluated by in vitro tests,where CR ratio,Individual Type Angle(ITA°)and chromatic aberration(∆E)were measured as the evaluation indicators by standard black/white cardboard,artificial leather and artificial sweat.In the clinical assessment,the anti-stain,waterproof,sweat resistance effect of the foundation products were evaluated through the ∆E change,before and after the treatment of products by staining,wetting,and sweating on forearm skin.There were significant differences in CR ratio of different types of samples on the standard black and white cardboard(P<0.05).ITA° of artificial leather had a significant increase after treatment(P<0.05).The color difference ∆E value of black cloth after dipping test was greater than 1.5,and the color difference ∆E value of leather before and after treatment with water and artificial sweat was less than 1.5.Clinical assessment showed that ∆E<50%,which had no significant difference in human skin color,before and after the test(P>0.05).The change trend of in vitro efficacy evaluation test was basically consistent with that of the visual evaluation and clinical assessment,indicated that the in vitro and clinical efficacy evaluation methods of foundation products are intuitive,quantifiable,and can be used to evaluate the efficacy of foundation products.
