NewHa+® Injection Grade Sodium Hyaluronate is supplied as a raw material for pharmaceutical and medical device development. It is intended for technical evaluation and qualification, not as a finished sterile injectable product.
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.

Injection grade sodium hyaluronate requires a different purchasing review from cosmetic or food grades. Buyers need more than a matching CAS number. Molecular weight, intrinsic viscosity, solution clarity, assay, residual impurities, microbial control and bacterial endotoxins all influence raw-material qualification.
NewHa+® is supplied as a white sodium hyaluronate powder under CAS 9067-32-7. Its specification includes identity testing against the Ph. Eur. reference spectrum, reaction of sodium, solution appearance, pH, assay, protein, nucleic acids, chlorides, heavy metals, iron, residual ethanol, microbial contamination and bacterial endotoxins.
Molecular weight and intrinsic viscosity are reported as batch values rather than fixed acceptance ranges in the available specification. This distinction matters during sourcing. A buyer with a defined rheology, filtration or device-performance target should state the required molecular-weight or intrinsic-viscosity window before sample evaluation.
The product is intended for evaluation by pharmaceutical, medical-device and formulation teams. The supplied powder still requires incoming qualification, process development and final-product controls. The raw-material grade name does not replace sterility testing, finished-product endotoxin assessment, biocompatibility work, stability studies or market-specific regulatory review.

The example batch has a reported molecular weight of 1.09 × 10⁶ Da and an intrinsic viscosity of 1.85 m³/kg. These are lot-specific results, not permanent limits for every supplied batch. They provide a useful starting point for screening, but the intended product concentration and rheological target must also be considered.
For projects with a defined molecular-weight or intrinsic-viscosity requirement, include the target value, acceptable range and preferred test method in the enquiry. This allows the available material and sample documentation to be reviewed against the same technical basis.
The specification requires a clear solution with absorbance not more than 0.01 at 600 nm. The stated pH range is 5.0–8.5 for a 0.5% solution, while the assay range is 95.0–105.0%. Together, these parameters support identity and quality screening before formulation work begins.
Solution clarity in the raw-material test does not guarantee clarity at the buyer’s final use level. Concentration, mixing conditions, other formulation components and the selected processing route can change the appearance and viscosity of the finished system.
The specification limits nucleic acids, protein, chlorides, heavy metals, iron, residual ethanol and microbial contamination. Bacterial endotoxins are specified at <0.05 IU/mg. These controls are especially relevant when a sodium hyaluronate raw material is being assessed for a regulated product.
The raw-material endotoxin result must not be treated as a finished-product release claim. The applicable final limit and test strategy depend on the product, dose, route of administration and regulatory framework. Buyers should include any method-specific or route-specific acceptance criteria in the technical request.
NewHa+® Injection Grade Sodium Hyaluronate can be evaluated as a raw material in pharmaceutical and medical device development. Molecular weight, intrinsic viscosity, solution clarity, impurity profile and bacterial endotoxin specification should be matched to the intended formulation and processing route.
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.
| Injection Grade | 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 |
NewHa+® Injection Grade
Sodium Hyaluronate can be evaluated as a raw material in pharmaceutical and medical device development. Molecular weight, intrinsic viscosity, solution clarity, impurity profile and bacterial endotoxin specification should be matched to the intended formulation and processing route.
Intra-Articular Formulations
Injection grade sodium hyaluronate is used in the development of sodium hyaluronate-based intra-articular formulations. Define the target concentration, molecular weight, intrinsic viscosity and finished-product rheology before selecting a batch.
Dermal Fillers and Soft-Tissue Products
The material can be assessed as a native sodium hyaluronate starting material or formulation component. Native sodium hyaluronate powder is different from a finished crosslinked gel. Crosslinking, residual reagents, extrusion performance and sterilization require separate process control.
Anti-Adhesion and Other HA-Based Medical Devices
This grade can also be evaluated for hyaluronan-based anti-adhesion products and other medical-device matrices. Raw-material purity, molecular characteristics and microbiological requirements should be matched to the intended device design.
To evaluate product suitability, please provide the intended application, target specifications, estimated quantity, destination market and document requirements.
| Information to Provide | Purpose |
|---|---|
| Intended product and destination market | Define the technical and document requirements |
| Target molecular weight or intrinsic viscosity | Support batch and grade matching |
| Planned concentration | Understand the required viscosity profile |
| Required test items and limits | Check specification compatibility |
| Estimated quantity and packaging | Prepare the sample or quotation |
The published specification provides the initial technical screening criteria. The example COA shows how the defined tests and reported values are presented for one production lot. For an order or qualification sample, use the lot-specific COA for the applicable batch rather than treating an example result as a universal value.
The example document identifies the product, CAS number, batch number, manufacturing date, analysis date, expiry date, packaging, test criteria, results and release conclusion. This gives QA and sourcing teams a traceable starting point for review.
If your project requires a particular document set, list each required document, language and destination market in the enquiry. The current availability and applicable version can then be included in the technical and commercial review.
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.
