Description

(S)-2-Hydroxypropanoic Acid Zinc Complex is a high-purity coordination compound of zinc and L-lactic acid, offering a bioavailable source of zinc. This product matters for applications requiring a stable, non-hygroscopic, and organoleptically neutral mineral supplement with excellent compatibility. It is primarily needed by manufacturers in the nutraceutical, food fortification, and pharmaceutical industries seeking to enhance product formulations with essential trace minerals.

Application

• Dietary Supplements & Nutraceuticals: As a bioavailable zinc source in capsule, tablet, and powder formulations.
• Food & Beverage Fortification: For enriching dairy products, infant formula, cereals, and functional beverages with essential zinc.
• Pharmaceutical Preparations: Used in mineral deficiency treatments and multivitamin-mineral complexes.
• Animal Nutrition (Feed Premixes): As a zinc supplement in feed for livestock, poultry, and aquaculture to support growth and immune function.
• Cosmetic & Personal Care: Incorporated into creams, lotions, and ointments for its skin-soothing and astringent properties.
• Technical & Industrial Uses: Potential applications as a catalyst or stabilizer in specific polymer and chemical synthesis processes.
