PEG-75 Shea Butter Glycerides

PEG-75 Shea Butter Glycerides is a PEG-modified emollient/surfactant used at low-to-moderate levels to solubilize and improve skin feel; it is generally well tolerated and not an active that alters skin physiology. Patch-test and clinical experience with PEG-fatty ester type emulsifiers suggest low but non-zero irritancy, with occasional stinging or eczema flare in highly reactive or barrier-compromised users (often due to surfactant-like behavior and individual sensitivity). Given sensitive-skin safety priorities, I rate it as gentle but not inert. Safety Notes: PEG-75 Shea Butter Glycerides is most often used as a water-dispersible emollient/solubilizing co-emulsifier in leave-on lotions/creams and cleansing systems, where it commonly appears at low supporting levels (~0.1–2%). In commercial products it can be found as low as ~0.05% in formulas that only need a mild slip/conditioning boost (e.g., facial cleansers, light lotions), while high-emolliency leave-on creams, body butters, and hair/skin conditioning products sold OTC can push it to ~5–10% to deliver richer feel and improved dispersibility of lipids. No specific EU/FDA maximum is set for this INCI beyond general cosmetic safety, so observed use is primarily constrained by sensorial targets, irritation tolerance, and stability/viscosity impacts.
