PEG-7 Glyceryl Cocoate is a non-ionic surfactant with dual function: wetting agent and hydrophilic emulsifier (HLB ~10–12) derived from coconut oil by ethoxylation with 7 ethylene oxide chains. Widely used in sulfate-free shampoos as a mild wetting agent, it improves the distribution of anionic surfactants without increasing their cuticular irritation. Hairswiss analyzes its molecular structure and formulatory role.
