What it is
A synthetic block copolymer made from ethylene oxide and propylene oxide, designed to act as a surfactant and emulsifier in cosmetic formulations.
How it works
Poloxamer 288 reduces the surface tension between oil and water, allowing them to mix into a stable emulsion. It also helps dissolve other ingredients and can boost the foaming or cleansing action of a product without stripping the skin's natural oils.
