NewHa+® crosslinked HA is available in a cosmetic-grade powder and an injection-grade gel. Each form has its own specification, quality profile and intended development route.
NewHa+® Crosslinked Sodium Hyaluronate is a crosslinked HA product family. Buyers may also encounter the names Crosslinked Hyaluronic Acid, Crosslinked HA and Sodium Hyaluronate Crosspolymer. The gel form may be described as a crosslinked hyaluronic acid hydrogel.
The powder is a dry raw material for topical cosmetic formulation work. The gel is a prepared viscous system for evaluation by qualified organizations developing regulated injectable products. They are not same: each form has its own specification, COA and technical approval route.

| Grade and form | Key characteristics | Typical selection context | Main technical focus |
| Cosmetic-grade powder | White or off-white powder or fibrous particles; content and molecular-weight reporting on the powder specification | Topical cosmetic formulation development, including water-rich and emulsion systems | Dispersion, hydration, clarity, pH, viscosity, preservative compatibility and finished-formula stability |
| Injection-grade gel | Transparent or semi-transparent viscous colloid; defined particle-size, rheology, extrusion, sterility and endotoxin criteria | Regulated injectable-gel research, product development and quality evaluation by qualified organizations | Rheology, particle-size distribution, extrusion behavior, degradation, sterility, endotoxin and packaging compatibility |
The powder and gel are not alternative packaging formats for the same grade. Choose by application and form first, then compare the relevant content, molecular-weight, rheology, particle-size and microbiological criteria.
The powder grade is a dry Crosslinked Sodium Hyaluronate raw material for cosmetic formulation work. Its reference COA covers identity, solution appearance, pH, content, molecular-weight reporting and microbiological quality.
The table separates the acceptance criteria shown on the reference COA from its reported batch result.

Seren und Essenzen
The powder grade can be assessed in water-rich serums and essences that use Sodium Hyaluronate Crosspolymer as a humectant and skin-conditioning ingredient. Establish a suitable dispersion process, then assess clarity, pH, viscosity and preservative compatibility before scale-up.
Gels and Mask Essences
Crosslinked HA powder can be considered for gels and mask essences where formula texture is part of the development target. Assess uniform dispersion, final viscosity, microbial control and package stability.
Cremes und Lotionen
In emulsions, the powder grade may be introduced through an aqueous-phase process established for the finished formula. Assess compatibility with emulsifiers, electrolytes, preservatives and other polymers, then verify viscosity and stability before scale-up.
The gel grade is a transparent or semi-transparent viscous colloid with defined osmotic pressure, particle-size, rheology, extrusion, residue, sterility and endotoxin criteria.
It is intended for evaluation by qualified organizations developing regulated injectable products. The grade and its COA do not by themselves establish finished-device approval or market authorization.
| Test item | Reference acceptance criterion | Reference batch result |
| Erscheinungsbild | Transparent or semi-transparent viscous colloid without visible foreign matter | Entspricht |
| Effective usage amount | 90%–120% of the labeled amount | 111% |
| Identifizierung | Meets the stated requirements | Entspricht |
| UV absorption at 260 nm | ≤1.0 | 0.24 |
| UV absorption at 280 nm | ≤1.0 | 0.19 |

1. die Hautbarriere zu verbessern
2. den Wasserverlust im Stratum corneum zu reduzieren
3. widersteht dem Eindringen von UV-Strahlung
4. mehrfache Feuchtigkeit aufrechterhalten
5. einen starken Oberflächenschutzfilm bilden
6. Hyaluronsäure ist von Natur aus im menschlichen Körper vorhanden, was sie äußerst sicher macht. Sie kann vom Körper vollständig absorbiert und verstoffwechselt werden. Das vernetzte Natriumhyaluronsäure-Gel hat eine gute Biokompatibilität und besitzt die Fähigkeit, dem Hyaluronidase-Abbau zu widerstehen, so dass Hyaluronsäure lange im Körper verbleiben und die Ausübung ihrer einzigartigen physikalischen und chemischen Eigenschaften stabilisieren kann.
7. Das vernetzte Natriumhyaluronsäure-Gel hat eine gute Stützkraft, Viskosität und Elastizität und neigt nicht zur Diffusion oder Verdrängung. Daher hat es einen guten Füll- und Formeffekt und die Formung hält lange an.
8. Die Geschwindigkeit des Stoffwechsels ist gleichmäßig. Die Geschwindigkeit der Absorption ist mit der Fülle und Festigkeit der Haut jeder Person verbunden.
