PEG-40 Hydrogenated Castor Oil
A polyethylene glycol ester of hydrogenated castor oil, widely used as an emulsifier and solvent in rinse-off and leave-on cosmetics. PEG-modified ingredients are graded as safe in cosmetics by the CIR when formulated at typical use levels.
Claims that PEG ingredients cause systemic absorption or contain dioxane are not supported by published cosmetic safety assessments. The concern stems from outdated manufacturing processes; modern PEG production uses well-controlled methods.
