Expert Verdict

Limited data. CIR polysilsesquioxane review provides class-level support, but silicate hybrid introduces a distinct structural element not specifically covered. Residual monomer and silicate leachability should be assessed. PMC literature on silsesquioxanes in cosmetics notes general safety of the class.
