乙基纤维素在新型水包油唇釉中的性能研究

Application of ethylcellulose in innovative oil-in-water lip gloss

通过模拟货架期的配方稳定性分析测试,成膜及抗水性测试以及Visia CR图像分析研究了乙基纤维素在新型水包油唇釉中的应用特点。使用Lum稳定性分析仪通过加速离心实验,验证含乙基纤维素的唇釉相比安慰剂唇釉更加稳定,成膜及抗水性测试表明含质量分数2.5%乙基纤维素的唇釉相比安慰剂成膜性更好、均匀,且抗水性更好。通过Visia CR进行图像采集,实验结果显示添加了2.5%乙基纤维素的配方涂抹于唇部后光亮度更高(p<0.05),可提供镜面光泽,色彩饱和度更高;配方的遮盖力显著提高(p<0.05)。

Via formulation stability analysis,film formation and water resistance tests,together with Visia CR image analysis,the application characteristics of ethylcellulose in innovative oil-in-water lip gloss was studied.With the accelerated centrifugation experiment of Lum dispersion analyzer,it was verified that the liquid lipstick containing ethylcellulose was more stable than the placebo without ethylcellulose.Film-forming&water resistance tests and the results of contact angle meter show that the lip gloss containing 2.5%ethylcellulose has better and more uniform film than the placebo,and its contact angle is higher.Images were captured by Visia CR.The results show that the lip gloss containing 2.5%ethylcellulose has a higher brightness(p<0.05),providing mirror-like luster and higher color saturation.The hiding power of the formula has significantly increased(p<0.05).
