is a sodium salt of the lactic acid. Sodium lactate belongs to the group of hydrating substances for the skin, that keeps the skin-own moisture and contributes to a slightly acidic pH value. The substances (glycerine, urea and organic acid) form together the Natural Moisturing Factor(NMF). In the EU sodium lactate is known as food additive E 325. The salt is easily soluble in water. The fluid is almost colourless and almost without scent or taste. Sodium lactate is also available in various concentrations (50 % / 60 %), on demand with adjusted pH value.
