Triethoxysilylethyl Polydimethylsiloxyethyl Dimethicone
What is Triethoxysilylethyl Polydimethylsiloxyethyl Dimethicone?
Triethoxysilylethyl Polydimethylsiloxyethyl Dimethicone is a synthetic organosilicon compound, a modified polydimethylsiloxane with a triethoxysilyl functional group. This chemical structure allows it to act as a reactive surface modifier in cosmetics, commonly applied to pigments, talcs, and mineral particles in makeup foundations, powders, and sunscreens. Upon exposure to moisture on the skin, the ethoxy groups hydrolyze, enabling covalent bonding to surfaces and forming a durable, hydrophobic silicone network. This mechanism improves pigment dispersion, adhesion, spreadability, and water repellency, resulting in even application, reduced rub-off, and a lightweight, velvety sensory experience without heaviness.
