Guanidinoacetic acid

Guanidinoacetic acid (CAS 352-97-6), also known as glycocyamine, betacyamine, or amidinoglycine, is a naturally occurring amino acid derivative and direct biosynthetic precursor to creatine. It carries no assigned E-code and is classified under HS code 29252000.

In personal care formulations, guanidinoacetic acid functions as a humectant and skin conditioner by attracting and retaining moisture at the stratum corneum level. In pharmaceutical and nutritional applications, it serves as a creatine precursor and pH buffer, supporting metabolic energy pathways in finished supplement and therapeutic products.

Guanidinoacetic acid is supplied as a white to slightly beige fine crystalline powder meeting food-grade and cosmetic-grade specifications. Procurement should confirm REACH compliance and supplier documentation for Ph.Eur. or FCC alignment depending on end-use. Standard packaging formats for B2B supply typically include 25 kg bags or fiber drums.
