Mechanism of Action
This ingredient functions by forming an extended, three-dimensional network on the skin's surface. Its inherent hydrophobic nature is crucial for its anti-sebum action, effectively minimizing shine and repelling water to provide skin protection and conditioning. Furthermore, it acts as a highly efficient dispersing agent, significantly improving the even distribution of both hydrophobic and untreated pigments, as well as organic and mineral UV filters in formulations. This mechanism leads to superior stay-in-place properties, extended wear, and pronounced transfer-resistance and water repellency in color cosmetics and sunscreens, all while imparting a desirable soft, lightweight sensorial feel.

Stability
Polysilsesquioxanes typically form robust, extended three-dimensional networks. More commonly, these polymers exist as open-chain structures comprising partial cages connected via siloxane bonds, often containing reactive silanol (SiOH) groups.
Safety
Safety Profile
The CIR Expert Panel has deemed polysilsesquioxanes, including POLYMETHYL/CAPRYLYLSILSESQUIOXANE SILICATE, safe for use in cosmetic formulations under current practices and concentrations. The highest reported maximum concentration for a related polysilsesquioxane, Polymethylsilsesquioxane, is 55.2% in other makeup preparations. The broader group of silicate ingredients is also considered safe, provided they are formulated to be non-irritating and not incidentally inhaled.
