What is Pharmaceutical Grade Sodium Hyaluronate CAS 9067-32-7?

Pharmaceutical Grade Sodium hyaluronate, the sodium salt form of hyaluronic acid, is a natural substance widely existing in human and animal bodies, and is the main component of soft connective tissues such as human skin, eye vitreous body and joint synovial fluid. Sodium hyaluronate is a polymer acidic mucopolysaccharide composed of n-acetylglucosamine and D-glucuronic acid disaccharide units. Its irregular crimp state in solution and its fluid dynamics characteristics give it important physical properties, such as moisture retention, lubricity, viscoelasticity and pseudoplasticity. Moreover, due to its good biocompatibility, sodium hyaluronate has been developed. It is widely used in the field of medicine.

Application

Pharmaceutical grade sodium hyaluronate products can be used as raw materials or auxiliary materials of drugs or medical devices for ophthalmic preparations, intra-articular preparations, postoperative anti-adhesion agents, wound healing external preparations and soft tissue fillers and other medical products, which are divided into two specifications: eye drop grade and injection grade.

Eye Drop	Lubricate, moisturize, improve efficacy, relieve dry eye, promote cornea, conjunctival injury healing, etc	Eye drops, eye moisturizer, contact lens care solution, eye wash solution, cavity lubricant, etc
	Promote wound healing	Topical preparations (gels, film agents, etc.)
	Drug or cell carrier/matrix	Eye drops, cell culture, external preparations, etc
	Repair mucosal damage, cartilage damage, etc	Oral pharmaceutical preparation
Injection	Viscoelastic, protects the corneal endothelium	Adhesives for eye surgery
	Lubricity, viscoelasticity, promote cartilage repair, inhibit inflammation, relieve pain, etc	Intra-articular injection
	Sodium hyaluronate and its derivatives have high molecular inertness, good biocompatibility and degradability	Post-operative anti-adhesion agent, medical plastic cosmetic dermal filler, tissue engineering scaffold material

Features

Sodium hyaluronate is widely distributed in the vitreous body, joints, umbilical cord, skin and other parts of the human body, and is an irreplaceable natural substance in the human body. The unique human self origin, biocompatibility, strong water locking ability, and viscoelastic lubricity make sodium hyaluronate highly valuable for application.

Pharmaceutical grade sodium hyaluronate can play important physiological roles in the body, such as retaining water, lubricating joints, promoting wound healing, and anti-aging.
