The Cosmetic Ingredient Review (CIR) Expert Panel affirmed the safety of PEG Soy Sterol, a group including this ingredient, for use in cosmetics. However, it is strongly advised against applying products containing this ingredient to compromised or damaged skin due to a potential for systemic toxicity and sensitization. Manufacturers must employ appropriate purification processes to remove trace contaminants like 1,4-dioxane and unreacted ethylene oxide, which are concerns with ethoxylated ingredients, prior to formulation.
