Description
L-Ornithine monohydrochloride (CAS 3184-13-2, EC 221-678-6) is a salt form of the non-proteinogenic amino acid ornithine, commonly referred to as Ornithine HCl or L-Ornithine hydrochloride. It carries no assigned E-code and is distinct from free-base ornithine in solubility and handling characteristics.
In personal care formulations, Ornithine HCl functions as a skin and hair conditioner by supporting the urea cycle pathway and contributing to moisture retention at the cellular level. In food and pharmaceutical applications, it serves as a pH buffer and humectant, stabilising formulations against oxidative degradation while maintaining water activity within defined limits.
Ornithine HCl is available in pharmaceutical-grade (Ph.Eur.-aligned) and food-grade (FCC-compliant) specifications as a white crystalline powder. The substance is registered under REACH and supplied in standard packaging formats suitable for industrial procurement. HS code 29224995 applies for import classification within the EU.
