  • Applications

    Carbonic acid, ammonium salt (1:1), mixt. with ammonium carbamate (1:1) (CAS 8000-73-5) is used primarily as a chemical intermediate in fertilizer production (notably via the ammonium carbamate/urea route) and as a source of ammonium ions in various formulations. It may act as a CO2-generating component in leavening systems for baked goods and as an alkalizing builder in cleaning and household products. In polymers, coatings, and adhesives, it can function as a carbamate precursor or stabilizing agent within formulations. It is also sometimes evaluated as a buffering or pH-adjusting additive in cosmetics and personal care products. Use is subject to local regulations and formulation limits.
