Methoxy PEG-10 Polysilsesquioxane

Used in cosmetic products as cleansing, humectant, skin conditioning, solvent and surfactant, cleansing. Methoxy PEG-10 Polysilsesquioxane is a resinous material composed of a mixture of three-dimensional siloxane polymers and 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 the methoxy PEG-10 propyl moiety. For the larger polymeric polysilsesquioxanes, some of the silicon atoms are not connected to other silicon atoms and instead have a silanol (SiOH) group. Methoxy PEG-10 Polysilsesquioxane is prepared by the hydrolysis and condensation of Methoxy PEG-10 Propyltrimethoxysilane.
