About
A common inorganic salt used as a pH buffer and mineral supplement in cosmetics, with an excellent safety profile similar to other food-grade phosphates.
Ammonium Phosphate (specifically the monobasic form, NH4H2PO4, or dibasic form, (NH4)2HPO4) is an inorganic salt used in cosmetic formulations as a pH buffering agent and mineral source. The pubchem safety score of 85 reflects its well-established safety profile. It is commonly used in food as an acidulant and mineral supplement, and has analogous applications in cosmetics where the phosphate anion provides buffering capacity. It is not subject to EU restrictions under Regulation 1223/2009.
