What Is Potassium Lactate?
Potassium lactate is the potassium salt of lactic acid. It is mostly used as a preservative and color stabilizer in meat products to extend their shelf life because of its ability to fight bacteria that would otherwise lead to food spoilage. Usage levels of potassium lactate for this purpose range from 1–4.8%.
In skin care, research has shown that potassium lactate can improve skin’s natural moisturizing factor (NMF) by increasing surface hydration.
