Sodium lactate is widely used in the food industry as a preservative and acidity regulator. It helps extend shelf life by inhibiting the growth of bacteria and molds in processed meats, poultry, and salad dressings. Due to its moisture-retaining properties, it improves texture and juiciness in cooked and processed meats. In cosmetics and personal care products, sodium lactate functions as a humectant, helping to retain moisture in the skin. It is commonly found in lotions, creams, and anti-aging products for its skin-conditioning benefits. It also plays a role in pH stabilization of formulations. In pharmaceuticals, it is used in intravenous fluids as an electrolyte replenisher and buffer. It helps correct acid-base imbalances in the body. Additionally, sodium lactate is used in some cleaning and industrial applications where a mild, biodegradable buffering agent is needed.
