Product Overview: Steareth-21

Steareth-21, also known as PEG-21 stearyl ether (CAS No. 9005-00-9), is a nonionic surfactant and emulsifier with a molecular structure of (C₂H₄O)₂₁C₁₈H₃₈O. As a polyoxyethylene derivative with 21 moles of ethylene oxide, this near-colorless white solid with a faint waxy scent has an HLB value of 15.5, making it ideal for forming stable oil-in-water emulsions, particularly with polar oils. It is widely used in cosmetic formulations like creams and lotions for its mild, low-toxicity profile.
