羟基乙酸对增稠体系粘度影响的研究

The Influence of Glycolic Acid on Viscosity of Thickening Agent

本文主要研究了70%羟基乙酸(AHA)对护肤产品配方常规4种增稠体系(黄原胶、羟乙基纤维素、U21以及TR-1)粘度的影响。实验数据表明:4种常规增稠体系在含有2%羟基乙酸护肤品配方体系中,都难以发挥增稠体系的作用。同时,本文也摸索并提出一种复配的增稠组合,本组合不仅能有效的增稠含有羟基乙酸体系的粘度,而且还能赋予产品水凝胶质地的感官特性。

This study mainly focuses on the influence of 70%glycolic acid on viscosity of thickening agent(Xanthan gum,Hydroxyethyl cellulose.U21 and TR-1).The experimental results show that conventional thickening agent cannot work in hydrogel formula with 2%glycolic acid.At the same time,this study provides one new thickening composition which increase formula viscosity and also make formula have special hydrogel texture.
