About Polymethylsilsesquioxane

Polymethylsilsesquioxane is a polymer obtained through the hydrolysis and condensation reaction of methyltrimethoxysilane.[1] The properties and sensory feel of finished products containing Polymethylsilsesquioxane may vary depending on the formulation concentration, the ingredients used with it, the formulation's acidity, and manufacturing conditions. In cosmetics, it is used to reduce light transmission so that the contents appear less see-through.[2]
