What Is Citrate Buffer?
Citrate buffer is a buffered mixture of the cosmetic ingredients sodium citrate and citric acid. It functions in cosmetics as a pH-adjusting ingredient to keep products in the acidic range of the pH scale. It can be sensitizing when used in high amounts, but the tiny amounts needed to establish a pH in cosmetics are not harmful to skin.
