PEG-12 Dimethicone

What PEG-12 Dimethicone is & what it does

A silicone emulsifier that stabilizes water-in-silicone formulas and adds a smooth, silky slip. It supports lightweight, water-resistant textures.

What does PEG-12 Dimethicone do in skincare?

PEG-12 Dimethicone is a water-dispersible silicone that acts as an emulsifier and skin conditioning agent. It helps blend silicone and water phases, improves spreadability, and can leave a smooth, silky feel on the skin. It is common in lotions, sunscreens, and primers where a light, even texture is desired.

Is PEG-12 Dimethicone safe?

PEG-12 Dimethicone is a modified silicone widely used in cosmetics and generally considered safe at the levels found in finished products. It is used to emulsify and condition and is not associated with significant irritation for most people. Those who prefer to avoid silicones or PEGs can check for them on the ingredient list.

Is PEG-12 Dimethicone comedogenic?

PEG-12 Dimethicone is generally considered low risk for clogging pores, as silicones of this type are large and tend to sit lightly on the skin. Pore-clogging potential still varies with the full formula and individual skin, so results differ from person to person. Patch testing is a reasonable step if you break out easily.
