化妆品保湿功效评价方法比较--以护肤膏霜为例

Comparison of Evaluation Methods of Cosmetic Moisturizing Efficacy-Taking Skin Cream as an Example

使用物理化学法和人体法分别对两种膏霜类化妆品进行保湿功效的评价,并将两种方法的保湿功效测试结果进行Pearson相关性分析比较。结果表明,物理化学法和人体法测得膏霜类化妆品保湿能力具有相似性,其中物理化学法和人体法的Pearson相关系数r为0.416,显著性P为0.048,表明物理化学法和人体法测得的保湿结果显著相关,为合理评价膏霜类化妆品保湿功效提供依据。

The physical-chemistry method and the human-body method were used to evaluate the moisturizing efficacy of two cream cosmetics,and the Pearson correlation analysis was carried out to compare their test results.The experimental results showed that the moisturizing ability of cream cosmetics measured by the two methods were similar.The Pearson correlation coefficient r of the physical-chemistry method and the human-body method was 0.416,and the significance P was 0.048,indicating that results obtained from two methods were significantly correlated.This study aimed to provide a basis for moisturizing efficacy evaluation of cream cosmetics.
