Description

Lactic Acid Zinc Salt is a coordination compound formed from zinc and lactic acid, offering a bio-based source of bioavailable zinc. This compound is valued for its stability, solubility profile, and role as a functional mineral supplement. It serves as a critical ingredient for manufacturers in the nutritional, pharmaceutical, and personal care industries seeking a high-quality zinc source.

Application

• Nutritional Supplements: Used as a source of bioavailable zinc in vitamin-mineral formulations, tablets, capsules, and liquid dietary supplements.
• Pharmaceuticals: Employed as an active pharmaceutical ingredient (API) or excipient in topical ointments, creams, and oral medications for zinc therapy.
• Cosmetics & Personal Care: Incorporated into skincare products, deodorants, and creams for its astringent, soothing, and antimicrobial properties.
• Animal Feed & Nutrition: Serves as a zinc fortifier in premixes and complete feeds for livestock, poultry, and aquaculture to support growth and health.
• Food Fortification: Utilized as a mineral nutrient in functional foods and beverages, subject to compliance with local food-grade regulations (e.g., FCC).
• Industrial Applications: Acts as a catalyst or stabilizer in specific polymerizations and chemical synthesis processes.
