Applications & Use Cases
- ▸ Supplied as a ~60% aqueous solution for use as an antimicrobial and shelf-life extender in processed meat, poultry, and seafood, where it controls Listeria and slows spoilage while buffering product pH.
- ▸ Used as a humectant and skin-conditioning agent (INCI: Potassium Lactate) in lotions, creams, and personal-care formulations to bind moisture in the stratum corneum.
- ▸ Functions as a pH buffer and acidity regulator in food, beverage, and HI&I cleaning formulations where a mild, food-grade lactate salt is preferred over inorganic buffers.
- ▸ Applied as a biodegradable component in low-corrosion deicing and antifreeze fluids and as a freezing-point depressant in water-treatment and industrial process applications.
- ▸ Serves as a chelating co-agent and carbon source in fermentation, electrolyte, and specialty industrial blends requiring a soluble, low-toxicity potassium-lactate source.
