The aim of the study was to evaluate the effects of hydrophilic microcrystalline cellulose, hydrophobic talc and mixtures of cellulose and talc when used as fillers in powdered bath cosmetics. A number of model formulations were developed that contained fillers in different compositions. Prototypical formulations were prepared and evaluated for their functional properties and skin-drying effect. An increase in the concentration of talc was found to reduce the ability of the formulations to emulsify fatty soils and, consequently, decrease the skin-drying effect after washing. Another result of the study is that a high content of talc does not significantly impair the foaming ability, and the presence of talc improves the stability of generated foam.

根据填料的选择评估粉状沐浴化妆品的质量

该研究的目的是评估亲水性微晶纤维素、疏水性滑石粉以及纤维素和滑石粉的混合物用作粉状沐浴化妆品填充剂时的效果。开发了许多模型配方，其中包含不同成分的填料。制备原型制剂并评估其功能特性和皮肤干燥效果。发现滑石浓度的增加会降低配方乳化脂肪污垢的能力，因此会降低洗涤后的皮肤干燥效果。研究的另一个结果是，高含量的滑石不会显着损害起泡能力，而滑石的存在提高了所产生泡沫的稳定性。
