常用增稠剂在化妆品配方中的应用研究

Application Research of Common Thickeners in Cosmetic Formulations

增稠剂是各类化妆品配方的骨架结构和核心基础,对产品的外观、流变性质、稳定性、肤感等都至关重要。选择常用和具有代表性的不同类型增稠剂,配制成不同浓度水溶液,测试其黏度、p H等理化性质,并采用定量描述分析法对其外观、透明度以及使用时、使用后的多项肤感指标进行感官测试,在此基础上对各种类增稠剂进行总结和概括,可为化妆品配方设计提供一定的参考。

Thickeners are the skeleton structure and core foundation of various cosmetic formulations. They are crucial for the appearance, rheological property, stability and skin-touch of product. Different types of thickeners which are common and representative were chosen, and their different concentrations aqueous solution were made. Then on this basis, the pH and viscosity of aqueous solution were tested. Meanwhile, the method of quantitative analysis method was used to evaluate the appearance, transparency and skin-touch during different times. Finally, the physic-chemical and sensory properties of different types of thickeners were summarized. This work could provide reference for cosmetic formula design.
