Sodium Hyaluronate (SH), CAS number 9067-32-7. is a glycosaminoglycan polymer derived from hyaluronic acid (HA) by sodium salt formation. It is a natural component of human connective tissues, known for its exceptional biocompatibility, viscosity, and moisture-retention properties. SH is widely used in medicine, cosmetics, and food industries due to its non-immunogenic and non-toxic nature.

Orthopedics: Injectable SH is used to treat osteoarthritis, reducing joint pain and improving mobility by restoring synovial fluid viscosity.
Ophthalmology: Employed in cataract and corneal surgeries as a viscoelastic agent to protect ocular tissues and maintain anterior chamber depth.
Wound Healing: Promotes tissue repair by providing a hydrated environment and reducing inflammation.
Skincare: Added to moisturizers, serums, and creams to enhance skin hydration, elasticity, and smoothness.
Anti-aging: Helps reduce wrinkles by supporting collagen synthesis and skin barrier function.
Approved as a food additive in some regions, SH is used in beverages, dairy products, and confectionery to improve texture and shelf life.
Biomaterials: Used in drug delivery systems, tissue engineering scaffolds, and biosensors due to its biocompatibility.
