Expert Verdict

As a PEG ether, potential trace-level 1,4-dioxane and ethylene oxide contamination from ethoxylation must be controlled via purification; Fruijtier-Pölloth (2005) safety assessment concluded PEGs safe as used in cosmetics. The "20" refers to an average of 20 ethylene oxide units; provides strong O/W emulsification with high HLB value
