What is Poloxamer 101?

Poloxamer 101 is a non-ionic block copolymer made from polyethylene oxide and polypropylene oxide units, creating a hydrophilic-lipophilic structure ideal for cosmetic applications. Developed as part of the poloxamer family, it serves primarily in rinse-off products like shampoos, body washes, and facial cleansers. Its function relies on amphiphilic properties: the hydrophobic polypropylene oxide block anchors into oils and dirt, while hydrophilic polyethylene oxide chains interact with water, reducing interfacial tension. This enables efficient dirt removal, foam generation, and stabilization of oil-in-water emulsions, ensuring product consistency and spreadability. In formulations, it helps create lightweight, non-residue cleansers suitable for daily use across skin types.
