摘要
Liquid crystal emulsifiers are widely used in skincare formulations due to their unique structural properties.In formulation development,components such as thickeners,oils,and co-emulsifiers significantly affect liquid crystal formation.Using polyglyceryl-10 stearate as an emulsifier,we investigated the effects of thickeners,oils,higher alcohols,and fatty acids on liquid crystal structure through controlled single-factor experiments.The results showed that xanthan gum(thickener),pentaerythrityl tetraisostearate(oil),and cetearyl alcohol(higher alcohol)produced optimal liquid crystal formation,with fatty acids providing additional benefits.Homogenization speed had the most pronounced impact-both excessively high and low speeds negatively affected the liquid crystal structure.
