Eye Drops Grade Sodium Hyaluronate Raw Material

The current NewHa+® specification and example batch COA support technical review before sampling or purchase. Formulation and quality teams can compare the documented molecular weight, intrinsic viscosity and key quality limits with their own ophthalmic formulation and destination-market requirements.

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 drops grade and injection grade.

Eye drops Grade	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

Eye Drops and Artificial-Tear Formulations

This grade can be evaluated as a sodium hyaluronate raw material for aqueous eye-drop and artificial-tear formulations. Review the batch-specific molecular weight and intrinsic viscosity against the target solution viscosity and processing requirements. Confirm clarity, pH, compatibility and stability in the finished formulation.

Contact Lens Care Solutions

Where permitted for the intended product and market, eye drops grade sodium hyaluronate may also be evaluated in contact lens care solutions. Confirm compatibility with the preservative or disinfecting system, packaging and finished-product microbiological requirements.

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.
