Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed pareth sulfates, including similar structures like Sodium C12-15 Pareth Sulfate, as safe for cosmetic use, provided formulations are non-irritating. While trace amounts of 1,4-dioxane, a manufacturing byproduct, may be present, the U.S. FDA indicates that levels found in cosmetics do not pose a consumer hazard. No specific SCCS opinion or maximum use concentration was identified for this ingredient.
