  • Helps skin trap moisture to improve hydration

Disiloxane description

Disiloxane is a multi-functional synthetic skin care ingredient used in cosmetics as a texture enhancer and anti-foaming agent. Falling under the siloxane umbrella, disiloxane is a type of silicone. Its volatility and low viscosity let it evaporate quickly, reducing dry-down time and leaving a smooth, weightless finish. When used in cosmetic formulas, it provides slip, enhances product wetness prior to dry-down and reduces tackiness. Disiloxane can also be used as a solvent to help deliver other ingredients to skin. This siloxane also forms a film on skin, helping skin to trap moisture and properly hydrate. Usage levels and safety of this ingredient as used in cosmetics haven’t been established; however, similar siloxane-type silicones are inert and not shown to pose a risk to skin.
