Description

Potassium L-Lactate is the potassium salt of L-lactic acid, a naturally occurring organic acid. This high-purity ingredient serves as a critical pH regulator, humectant, and potassium source in advanced formulations. It is essential for manufacturers in the pharmaceutical, food, and personal care industries seeking natural, effective, and compliant ingredients. Our global supply ensures consistent quality and reliable availability for your production needs.

Application

• Pharmaceutical Formulations: Used as a buffering agent and electrolyte replenisher in parenteral solutions, dialysis fluids, and oral rehydration salts.
• Food & Beverage Industry: Functions as a pH control agent, flavor enhancer, and shelf-life extender in meat products, dressings, and beverages, often meeting FCC standards.
• Cosmetics & Personal Care: Acts as a highly effective humectant and moisturizer in skin creams, lotions, and serums, helping to maintain skin hydration.
• Animal Nutrition: Incorporated into feed and water supplements as a source of bioavailable potassium and an acidifier for gut health.
• Biotechnology & Cell Culture: Serves as a component in buffer systems and fermentation media where precise pH control is required.
• Industrial Applications: Employed in metal treatment processes and as a biodegradable component in certain specialty chemical formulations.
