Injection grade sodium hyaluronate powder is used primarily in various non-enteric preparations such as intra-articular, intra-ocular, and intradermal injections due to its excellent lubricity, viscoelasticity, and its biocompatibility. Injectable grade sodium hyaluronate powder is important in the medical and cosmetic fields because of its ability to provide lubrication, repair damaged tissue, inhibit inflammation and relieve pain.
Sodium Hyaluronate is the sodium salt of hyaluronic acid (HA), also known as hyaluronan, a glycosaminoglycan consisting of D-glucuronic acid and N-acetyl-D-glucosamine disaccharide units. HA is one of several glycosaminoglycan components of the extracellular matrix of connective tissue. HA is a naturally occurring biopolymer involved in numerous biological processes including tissue hydration and structural scaffolding. HA is increasingly used as a reagent and investigated in bioengineering applications. Its use as a reagent includes hydrogels for use in aesthetics, ophthalmology, rheumatology, urology, wound healing, and 3D bioprinting.
