  • Applications

    Sodium lactate is widely used as a buffering agent and humectant across several industries; in food processing, it serves as an acidity regulator, moisture-retention agent, and, in some products, a preservative to extend shelf life; in cosmetics and personal care, it acts as a humectant and pH adjuster to improve moisture retention and formula stability; in pharmaceuticals, it is used as a buffering agent and formulation stabilizer; in cleaning and household products, it serves as a pH adjuster and humectant to support performance; in agriculture/animal feeds, sodium lactate can be used as a humectant and preservative in processed feeds.
