Int J Toxicol. 2021 Jul-Aug;40(1_suppl):34S-85S. doi: 10.1177/10915818211014499.

Abstract

The Expert Panel for Cosmetic Ingredient Safety (Panel) assessed the safety of Phosphoric Acid and its salts (31 ingredients), which are reported to function as buffering agents, corrosion inhibitors, chelating agents, and pH adjusters in cosmetic products. The Panel reviewed data relating to the safety of these ingredients and concluded that Phosphoric Acid and its salts are safe in the present practices of use and concentration in cosmetics when formulated to be nonirritating.

Keywords: cosmetics; phosphoric acid; safety; salts.
