Buffering Agents

Product Introduction

Cosmetic buffers are substances that build and maintain a certain pH level in cosmetics. Adding acid lowers the pH of the product; adding a buffer maintains the pH at a certain level. The components of a buffer mixture are in chemical equilibrium. When concentrating, diluting and introducing relatively small amounts of a substance that interacts with one component of a buffer system, the pH of such a system changes only slightly.
