Methyl/Phenyl Polysilsesquioxane
Used in cosmetic products as opacifying and slip modifier. Methyl/Phenyl Polysilsesquioxane is a resinous material composed of a mixture of three-dimensional siloxane polymers and/or oligomers with cage structures. For the oligomers, each silicon atom in the polysilsesquioxane is connected via oxygen atoms to three other silicon atoms and can be represented by the empirical formulation RSiO3/2, where R represents a mixture of methy and phenyl groups. For the larger polymeric polysilsesquioxanes, some of the silicon atoms are not connected to other silicon atoms and instead have a silanol (SiOH) group.
