摘　　要：对最新开发的护肤品专用流变改性剂CarbopolAqua SF-1 OS聚合物在含二氧化钛乳化体系中的性能进行了深入的研究。在基础乳化体系配方和防晒配方中,测试了新生代聚合物与质量分数为5%~20%不同包裹类型的二氧化钛的兼容性,并从pH、黏度、显微镜下的色粉分散性能、肤感变化、加速老化稳定性等方面比较了新生代聚合物和几款市场对照品之间的区别。实验结果表明,在含所测试的多种二氧化钛的乳化体系配方中,CarbopolAqua SF-1 OS聚合物相比对照品具有更好的悬浮稳定性、外观、质地、肤感、二氧化钛分散性能和抗再积聚性能。Research on the application of new skin care rheology modifier, Carbopol Aqua SF-1 OS polymer, in emulsion containing titanium dioxides was conducted in this paper. The compatibility of this new generation polymer with 5%~20%（mass percentage） of differently coated titanium dioxide samples, based on both a basic emulsion system and a sun care formulation, was tested; and the performance of new generation polymer was compared with those of several market benchmark products in terms of p H, viscosity, pigment dispersion under microscope, skin sensory and stability in accelerated stability test. Results showed： Carbopol Aqua SF-1 OS polymer substantially outperforms the benchmarks in emulsion suspension and stabilization, appearance, texture, sensory, titanium dioxide dispersion and anti re-agglomerating.
