Ingredient Info

Tromethamine is a pH buffer and alkalizing agent used in skincare formulations to neutralize acids and maintain skin-friendly pH levels. It's not typically a featured active ingredient but rather a behind-the-scenes helper that stabilizes product formulations.



Benefits

  • Helps maintain optimal pH balance in skincare products
  • Stabilizes formulations containing acidic actives like retinoids or vitamin C
  • Allows safer delivery of potent ingredients without excess irritation

Potential concerns

  • Limited data on direct skin effects as a standalone ingredient
  • Generally used at low concentrations, minimizing irritation risk
  • May cause irritation if formulation pH becomes too alkaline

Science: The provided literature focuses on tromethamine's use as a pain-relief agent in ophthalmic settings rather than skincare applications. Limited peer-reviewed data is available specifically for its use in topical cosmetic formulations, though it is recognized as a safe, FDA-approved buffer agent in pharmaceutical and cosmetic products.
