Triethoxysilylethyl Polydimethylsiloxyethyl Hexyl Dimethicone

Triethoxysilylethyl polydimethylsiloxyethyl hexyl dimethicone is a silicon-based polymer used in skincare formulations. It belongs to a class of ingredients known as silicones, which are synthetic compounds derived from silicon and oxygen. This particular variant is designed to form a thin, breathable film on the skin's surface.Its primary function is to condition the skin by creating a smooth, protective barrier that can help improve the feel and appearance of the skin whilst allowing moisture and air to pass through.

This ingredient works by depositing a thin, flexible film across the skin. The silicone polymer chains align on the skin surface, creating a smooth, even coating that minimises the appearance of texture irregularities and provides a light protective barrier.Unlike occlusive oils, this type of silicone is designed to be breathable, meaning it allows water vapour and air to pass through whilst still offering some degree of protection against transepidermal water loss and external irritants.

This ingredient is used by formulators rather than consumers directly. When present in your skincare product, simply apply as directed by the manufacturer. It typically works well as part of serums, moisturisers, and primers. No special application technique is needed.

Generally well-tolerated and recognised as safe in cosmetic use. Those with silicone sensitivity are rare, but patch testing is advisable if you have a known silicone sensitivity.
