Description

Potassium lactate (CAS 996-31-6 ), also designated E326 , is the potassium salt of lactic acid supplied primarily as a concentrated aqueous solution. It functions as a humectant, pH buffer, and antimicrobial synergist across food, personal care, and pharmaceutical applications. In processed meats and ready-to-eat foods, it extends shelf life by suppressing pathogen growth, particularly Listeria, while contributing a mild, clean flavor profile. Food formulators also use it as an acidulant and buffering agent in sauces and marinades. It is frequently utilized in bakery products where potassium-based labeling is preferred over sodium alternatives. In cosmetic formulations, it acts as a moisturizing agent and pH adjuster in lotions, creams, and leave-on skin care products. Its hygroscopic character supports water retention in the finished formula for various personal care items. Pharmaceutical manufacturers incorporate it as a buffering excipient in topical preparations and oral dosage forms requiring controlled acidity. Potassium lactate is most commonly supplied as a 60% aqueous solution, though higher-concentration and dry powder forms are available for specific applications. Food-grade material is produced to FCC specifications for global distribution. Pharmaceutical-grade material is available to USP and Ph. Eur. standards to meet strict regulatory requirements. Packaging typically ranges from drums and IBCs to bulk tanker supply for high-volume food processing operations. Contact us for supply of Potassium lactate Request Quote
