Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has not specifically reviewed Palmamidopropyl Trimonium Methosulfate; however, a broader group of related 'trimonium' ingredients were deemed safe for rinse-off products and at concentrations up to 0.25% in leave-on products in 1997. While a cosmetic safety assessment suggested it is not expected to cause irritation with prolonged use at low levels, a general likelihood of irritation exists, which intensifies when formulated with other potentially problematic ingredients.
