Poloxamer 182
What is Poloxamer 182?
Poloxamer 182 is a nonionic surfactant from the poloxamer series, composed of a triblock copolymer with hydrophilic polyethylene glycol blocks flanking a hydrophobic polypropylene glycol core. This structure gives it an amphiphilic nature ideal for cosmetic applications. Typically used in rinse-off cleansers, shampoos, body washes, and micellar solutions, it lowers surface tension to facilitate the dispersion of oils and dirt into water. By forming micelles, it lifts impurities from the skin and hair for thorough removal during rinsing. It also acts as an emulsifier to blend oil and water phases stably and as a solubilizer to incorporate fragrances and other lipophilic actives into clear, aqueous products, enhancing formula performance and sensory appeal.
