Poloxamer 407

What Poloxamer 407 is & what it does

Poloxamer 407 is a synthetic nonionic block copolymer made from polyoxyethylene and polyoxypropylene units. In skincare and sunscreen formulas it works as a surfactant, emulsifier, and mild cleansing agent, helping disperse oils and keep the product stable. A notable property is its ability to form clear gels at higher concentrations, which is useful in transparent or rinse-off products.

Poloxamer 407 is a long-established cosmetic ingredient and is generally considered safe for use in skincare and sunscreen at typical levels. It is a mild nonionic surfactant, so it is usually well tolerated, though any cleansing or surfactant ingredient can be drying for some skin types. People with very sensitive skin can patch test if concerned.
