Sodium acetylated hyaluronate, also called Super Hyaluronic Acid, is used in various cosmetics. It is a specialty Sodium Hyaluronate (HA) derivative which is synthesized from the Natural Moisturizing Factor HA by acetylation reaction. The hydroxyl group of HA is partially replaced with acetyl group; it owns both lipophilic and hydrophilic properties. This helps to promote high affinity and adsorption properties for skin. Sodium acetylated hyaluronate has a fresh and not-sticky feeling that can provide superb moisturizing, repair skin barrier, improve skin elasticity, and leave skin smooth.
Compared with the same concentration of hyaluronic acid, it is characterized by a much greater capacity to retain moisture in the epidermis and good skin affinity. Because of this, it can keep skin moist for long times.
