Tromethamine description

Tromethamine is a triol, a type of alcohol that contains three hydroxyl groups which consist of bonded hydrogen and oxygen atoms. It serves as a pH adjusting ingredient in skin care formulations. When used in cosmetic formulas it assists in neutralizing more acidic substances due to its alkaline pH. Although skin is naturally acidic, with a pH ranging between 4 and 5, altering skin’s natural delicate pH balance can cause irritation. The balance that tromethamine brings to a formula’s pH can help prevent this. As a raw material tromethamine appears as a white crystalline powder. The Cosmetic Ingredient Review Expert Panel concluded that it’s safe for use in current cosmetic preparations. It’s commonly used in concentrations between 0.00009–3.7%. Outside of cosmetics, tromethamine is used in medical applications to reduce acidity.
