PEG-10

What PEG-10 is & what it does

A silicone elastomer emulsifier that stabilizes formulas while giving a smooth, cushiony, soft-focus finish. It helps refine texture and lock in actives.

What does PEG-10 do in skincare?

PEG-10 is a polyethylene glycol used mainly as a solubilizer, humectant, and texture aid. In skincare and sunscreen formulas it helps mix oil- and water-based components, can attract moisture, and contributes to a smooth product feel. The number 10 refers to the average length of the polymer chain.

Is PEG-10 safe?

PEG-10 is a widely used cosmetic ingredient in the polyethylene glycol family and is generally considered well tolerated in formulated products. Some people prefer to avoid PEGs for personal reasons, and purity of manufacturing can matter for this class of ingredients. If you have sensitive skin, patch testing the full product is reasonable.

Is PEG-10 natural or synthetic?

It is synthetic. PEG-10 is a polyethylene glycol made by polymerizing ethylene oxide, so it is a manufactured ingredient rather than a naturally occurring one.
