Poloxamer 123
What is Poloxamer 123?
Poloxamer 123 is a triblock copolymer made from ethylene oxide and propylene oxide units, creating a structure with hydrophilic polyethylene oxide blocks flanking a hydrophobic polypropylene oxide core. This amphiphilic nature allows it to self-assemble into micelles in water, effectively trapping oils, dirt, and fragrances. In skincare, it appears in shampoos, body washes, lotions, creams, toners, and micellar waters. It lowers surface tension to improve product spreadability and wetting, stabilizes oil-in-water emulsions by forming protective films at interfaces, and solubilizes lipophilic ingredients into clear aqueous formulas. Its versatile functionality supports gentle cleansing and uniform textures without contributing to pore clogging.
