Ornithine hydrochloride

Ornithine hydrochloride (CAS 3184-13-2), also known as L-Ornithine monohydrochloride, is the stabilized salt form of the non-proteinogenic amino acid ornithine. It is preferred for commercial supply due to its improved solubility and shelf stability. It functions as a bioactive ingredient and formulation component across pharmaceutical and cosmetic applications.

In dietary supplements and functional foods, it is used as an active amino acid ingredient in products targeting sports recovery, liver support, and metabolic health formulations. Pharmaceutical manufacturers incorporate it into infusion solutions and amino acid preparations where precise dosing and high purity are required for compounded formulations.

In food and beverage applications, it carries FEMA 4190 status and is used as a flavor-modifying and buffering agent to enhance the profile of various consumer products. Cosmetic formulators use it in skin care products as a humectant and stabilizing component in amino acid-enriched serums and creams to improve moisture retention and texture.

Ornithine hydrochloride is supplied as a white crystalline powder. It is available in food-grade and pharmaceutical-grade specifications, with USP and FCC grades commonly offered. These grades meet regulatory requirements across different end markets. Bulk quantities are standard for industrial buyers, with smaller packaging available for specialty formulators.
