Overview

Tromethamine is an ingredient based on amino acids. This ingredient is commonly used as a pH adjuster. It has a high pH, which means it is basic, or alkaline, so adding tromethamine to a skincare product will increase its overall pH level.

This is useful for hydrating some polymers, such as acrylate C10-30 alkyl methacrylate copolymer, which requires specific pH adjusters in order to unfold and function properly.

Tromethamine is a white crystalline solid that will impart a particular fragrance when dissolved in the water phase.
