POLOXAMER 238

Safety grade: A

Poloxamer 238 is a synthetic polymer that acts like a molecular bridge, helping to mix oil and water together in cosmetic products. It's a thickening agent that also helps stabilize formulations so they don't separate over time.

This ingredient works as an emulsifier and surfactant to blend ingredients that normally don't mix, while also thickening the product and keeping it stable and uniform.
