Description
Potassium lactate (E 326) is the potassium salt of lactic acid, supplied as a syrupy aqueous liquid. It is commercially available under trade names including Purasal P, Purasel P, and Conclyte K. The CAS number is 996-31-6.
In processed meats and ready meals, potassium lactate lowers water activity and raises pH buffering capacity, inhibiting pathogen growth and extending shelf life without altering flavour profiles. In personal care formulations, it functions as a humectant by binding moisture within the skin matrix, and serves as a mild pH adjuster in leave-on products.
Potassium lactate is available in food-grade and pharmaceutical-grade forms, with compliance to E 326 (EU food additive regulation), FCC, and Ph.Eur. standards depending on grade. It falls under REACH registration requirements for supply within the European Economic Area. Packaging typically follows bulk liquid formats standard for aqueous salt solutions.
