摘要
采用皮肤镜拍摄不同清洁产品使用前后的皮肤显微图片,结合3种不同的评价方式对图片污垢残留情况进行定量分析,比较不同评估方法评定产品清洁力的差异性。结果表明,色差(ΔΕ)法和污垢面积法检测结果显示净化乳清洁力优于洗发露,L*(亮度)值法检测显示洗发露和净化乳清洁力差异不显著。志愿者同阶段的显微图片显示,净化乳测试区域污垢残留量少于洗发露测试区域污垢残留量,表明净化乳清洁力优于洗发露,与色差法和污垢面积法检测结果一致。色差法和污垢面积法能真实评估产品清洁能力,具有良好的应用前景。
Dermoscope was used to record the skin micrograph before and after the use of different cleaning products,and three different evaluation methods were further used to quantitatively analyze the dirt residue in the pictures.The difference in the detergency evaluated by different evaluation methods was compared.The results showed that the detergency of cleansing milk was better than that of shampoo byΔΕand dirt area methods;however,there was no significant difference in detergency between cleansing milk and shampoo as shown by L*value method.According to the skin microscopic pictures of the volunteers at the same stage,it could be directly seen that the residual amount of dirt in the test area for cleansing milk was less than that in the test area for shampoo,indicating that the cleansing power of the cleansing milk was better than that of shampoo.The results were consistent with those obtained byΔΕand dirt area methods.It showed thatΔΕand dirt area methods were more suitable to reflect the real detergency of products and had a good application prospect.
