Lauryl PEG-10 Tris(Trimethylsiloxy)Silylethyl Dimethicone

Lauryl PEG-10 Tris(Trimethylsiloxy)Silylethyl Dimethicone is a hybrid silicone ingredient that combines silicone chemistry with polyethylene glycol (PEG) technology. It functions as an emulsifier and skin conditioning agent, helping to blend water and oil-based ingredients that would not naturally mix.In skincare formulations, it works to stabilise emulsions—the creams, serums and lotions that combine water and oil phases. It is used in relatively small amounts (typically under 1%) and is found in a minority of skincare products.

This ingredient acts as a bridge between water and oil molecules, positioning itself at their interface to prevent separation. Its silicone backbone provides hydrophobic (oil-loving) properties, whilst its PEG chain offers hydrophilic (water-loving) qualities, allowing both phases to coexist stably in a single product.On the skin, it deposits a thin, conditioning film that can feel smooth and silky, though it is volatile enough not to build up significantly with repeated use.

This ingredient is a formulation component rather than an active ingredient you need to use strategically. Simply use products containing it as directed. Emulsifier-rich formulations are generally well-tolerated as part of regular skincare routines; there is no need to alternate use or cycle on and off.

Generally well-tolerated by most skin types. Non-comedogenic at typical use levels. Those with sensitivities to silicones should patch-test first.
