Disiloxane

What Disiloxane is & what it does

Disiloxane is a low molecular weight silicone, the simplest member of the siloxane family with two silicon atoms linked by an oxygen bridge. In skincare and sunscreen formulas it is commonly used as a lightweight, volatile solvent and emollient that spreads easily and leaves a dry, non-greasy finish. A notable property is its very low viscosity, which helps thin out heavier ingredients and improve a product's slip.

What does Disiloxane do in skincare?

Disiloxane is a lightweight, volatile silicone commonly used as a solvent and emollient. It spreads easily and helps thin out heavier ingredients, leaving a dry, silky, non-greasy finish. In sunscreens it can improve how smoothly the product applies.

Is Disiloxane natural or synthetic?

Disiloxane is a synthetic silicone, manufactured rather than sourced from plants or animals. It belongs to the siloxane family and is one of the simplest silicone structures. Like other silicones it is produced industrially.

Does Disiloxane clog pores?

Disiloxane is a volatile, lightweight silicone that tends to evaporate from the skin rather than build up, and silicones of this type are generally regarded as low risk for clogging pores. Individual skin reactions can vary, so results may differ from person to person. If you are prone to breakouts, patch testing a new product is sensible.
