About

A mild ammonium salt used as a pH adjuster and leavening agent in cosmetics, with a long history of safe use similar to other food-grade carbonate compounds.

Ammonium Carbonate is a salt of ammonia (NH3) with carbonic acid, occasionally used in cosmetics as a pH adjuster and leavening agent. It decomposes at elevated temperatures or in acidic conditions to release ammonia and carbon dioxide, which can be advantageous in formulations where gas generation is controlled. The pubchem_safety_score of 85 reflects its favorable safety profile, similar to other ammonium salts used in food and cosmetics. It is not restricted under EU Regulation 1223/2009.

Skin benefits
