  • Applications

    Sodium Lactate, L- (CAS 867-56-1) is used as a humectant and pH adjuster in cosmetics and personal care formulations. In food processing, it is commonly used as an acidity regulator and humectant to aid shelf life, moisture retention, and texture in processed meats and other products. In pharmaceuticals, it serves as an excipient, buffering agent, and stabilizer for various formulations, and helps adjust solution osmolarity. In cleaning and household products, it functions as a humectant and pH stabilizer to improve formulation stability and cleaning performance. In coatings and inks, it can act as a humectant to control drying times and improve consistency of films. In polymers/plastics, it can be used as a processing aid or plasticizer for biopolymers such as PLA, improving flexibility.
