Potassium citrate - 866-84-2

Key Functions: Cosmetics & Personal Care, Food Contact & Additives

Potassium citrate functions as a buffering and chelating agent (EC 2024). It is produced via neutralization of citric acid with potassium bicarbonate or potassium carbonate (HSDB 2003). The United States Food and Drug Administration (U.S. FDA) recognizes potassium citrate, as tripotassium citrate monohydrate (CAS #6100-05-6), as an indirect food additive under 21 CFR §175.300 and as generally recognized as safe (GRAS) under 21 CFR §184.1625 (U.S. FDA 2024). The Cosmetic Ingredient Review (CIR) Expert Panel concluded potassium citrate is safe for use in cosmetics in the present practices of use and concentration, up to 0.5% in leave-on products and up to 0.6% in rinse-off products (CIR 2014).
