Acetylated Sodium Hyaluronate
Acetylated sodium hyaluronate with both hydrophilicity and lipophilicity for double moisturizing, antioxidant, anti-inflammatory, and barrier-repair performance in daily cosmetics.
Sodium acetylated hyaluronate is produced by grafting part of the hydroxyl groups of sodium hyaluronate into acetyl groups, giving it both hydrophilicity and lipophilicity for double moisturizing, antioxidant, anti-inflammatory, barrier-repair, and skin-elasticity benefits.
Appearance is white or light yellow powder, easily soluble in water.
