Sodium Hyaluronate

Sodium hyaluronate is the sodium salt form of hyaluronic acid (HA), a large polymer naturally found in the skin that acts as a sponge to help the skin retain water, maintaining plumpness and elasticity. It is officially classified as a humectant and skin-conditioning agent (CAS# 9067-32-7). In solution, sodium hyaluronate dissociates into a hyaluronic acid molecule and a sodium atom, making the two functionally interchangeable in cosmetic formulations. The salt form is noted to be more stable, easier to formulate with, and less costly than hyaluronic acid.
