About Potassium Lactate

Potassium Lactate is the potassium salt of lactic acid.[1] The solubility and charge state of Potassium Lactate vary depending on the components forming the salt and the acidity of the formulation, which also affects how it interacts with other ingredients. In cosmetics, it is used to buffer the formulation so its acidity does not change abruptly, to attract moisture to the formulation and skin surface and help maintain hydration, and to leave the skin surface soft and smooth.[2]
