Valuable CAS 7360-53-4 / BUFFERING

Aluminum Triformate is a buffering and astringent agent, commonly found in oral care and astringent toners. It temporarily contracts tissues and forms a mild protective barrier on the skin.

Summary

buffering astringent

Science

Mechanism of Action

It functions by releasing aluminum ions that interact with skin proteins, leading to their precipitation and subsequent temporary tissue contraction. This mechanism also contributes to its buffering capacity and, in specific contexts, enzyme inhibition.
