Ethyl Trisiloxane
What is Ethyl Trisiloxane?
Ethyl Trisiloxane is a synthetic organosilicon compound, a short-chain trisiloxane featuring silicon-oxygen linkages with ethyl and methyl substituents. This volatile fluid belongs to the silicone family widely employed in cosmetics, particularly in leave-on products like serums, mists, primers, and hair sprays. It functions by rapidly spreading across the skin due to its low viscosity and surface tension, then evaporating quickly to deposit a barely-there, silky film. As a skin conditioner, it enhances softness and suppleness without greasiness. In formulations, it controls thickness, ensuring even distribution, stability, and desirable sensory qualities like quick absorption and non-tacky finish, making products more user-friendly across various textures.
