Trisiloxane

What Trisiloxane is & what it does

A light, spreadable silicone that gives a fast, silky glide and helps distribute filters and pigments evenly. It leaves a smooth, dry feel.

What is Trisiloxane and what does it do in sunscreen?

Trisiloxane is a light, spreadable silicone used as an emollient. It gives a fast, silky glide and helps distribute UV filters and pigments evenly across the skin, leaving a smooth, dry feel. In a sunscreen it improves application and texture rather than adding UV protection itself.

Is Trisiloxane safe?

Generally yes. Silicones like Trisiloxane sit on the surface of the skin and are well tolerated by most people, with a long record of cosmetic use. Our data does not flag it as an allergen. It is a skin-feel ingredient rather than an active.

Does Trisiloxane clog pores?

Generally no. Trisiloxane is a light, volatile-feeling silicone that largely sits on the surface and does not behave like a pore-clogging oil, and our data does not flag it as comedogenic. Lightweight silicones are usually considered low-risk for breakouts. If a product clogs your pores, heavier oils and waxes are the more likely cause.

Is Trisiloxane a silicone?

Yes. Trisiloxane is a small, lightweight member of the silicone family, used for its fast, silky spread. It is one of the lighter silicones, which is why it leaves a dry rather than heavy finish. It helps other ingredients glide on evenly.

Is Trisiloxane natural or synthetic?

It is synthetic, made in a lab from silicon-based building blocks. It does not occur in nature in this form. That lab-made consistency is part of why it gives such a predictable, silky feel.
