Guanidine carbonate

Guanidine carbonate (CAS 593-85-1, EC 209-813-7) is an inorganic salt of guanidine, also referred to commercially as guanidinium carbonate or diguanidinium carbonate. It carries no assigned E-code and is classified under HS code 29252000 within the salts and minerals category.

In personal care formulations, it functions as a pH buffer and skin conditioner by donating or accepting protons to maintain target alkalinity ranges. In polymer processing, it acts as a heat stabilizer and catalyst, moderating degradation reactions at elevated temperatures. Pharmaceutical and food-grade applications exploit its antimicrobial activity against a range of bacterial strains.

Guanidine carbonate is supplied as a white crystalline powder in technical and pharmaceutical-grade specifications, with compliance documentation available for REACH registration. Procurement teams can request material aligned with Ph.Eur. or FCC monograph requirements depending on end-use. Standard packaging formats include 25 kg bags and intermediate bulk containers.
