Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel deemed polyethylene glycol (PEG) diesters, a broader category, safe when formulated to be non-irritating, though a specific assessment for PEG-3 Dioleoylamidoethylmonium Methosulfate is not available. EWG VERIFIED™ allows its use but mandates adherence to restrictions and warnings, particularly concerning potential contamination from ethoxylation byproducts like Ethylene Oxide and 1,4-Dioxane. Respiratory concerns are noted for inhalable product forms. EWG identifies 'LOW' concerns for cancer, allergies & immunotoxicity, and developmental & reproductive toxicity. There is no SCCS opinion or direct FDA status explicitly stated for this ingredient.
