PEG-2 Stearate
What PEG-2 Stearate is & what it does
PEG-2 Stearate is a polyethylene glycol ester of stearic acid used as a nonionic emulsifier and surfactant in cosmetic and sunscreen formulas. It helps blend oil and water phases so a lotion or cream stays stable and uniform. The low number indicates a short polyethylene glycol chain, which makes it a relatively oil-loving emulsifier.
What does PEG-2 Stearate do in skincare?
PEG-2 Stearate is a nonionic emulsifier and surfactant. It helps oil and water blend together so creams and lotions stay smooth and stable rather than separating.
Is PEG-2 Stearate safe?
PEG stearate emulsifiers are common in cosmetics and are generally regarded as safe at the levels used in finished products. They are used in controlled amounts, and reactions are uncommon for most skin types.
Is PEG-2 Stearate natural or synthetic?
It is synthetic, made by combining polyethylene glycol with stearic acid, a fatty acid. The stearic acid portion can come from plant or animal sources, so origin depends on the supplier.
