Sodium Malate
What is Sodium Malate?
Sodium malate is the sodium salt of malic acid, an alpha-hydroxy acid naturally occurring in fruits like apples and pears. This water-soluble compound, with the formula C4H5NaO5, serves as a humectant and skin conditioner in cosmetics. It functions by attracting and binding atmospheric moisture to the skin's surface layers, promoting sustained hydration without greasiness. Commonly found in moisturizers, serums, toners, and cleansers, it helps maintain optimal product pH through buffering action. Its gentle nature makes it suitable for daily use across various formulations, supporting skin's natural moisture balance and flexibility. Produced via neutralization of malic acid with sodium hydroxide, it integrates seamlessly into water-based products for enhanced texture and efficacy.
