Sodium Hyaluronate Crosspolymer
Lifeworth supplies sodium hyaluronate crosspolymer, a modified hyaluronic acid ingredient designed for cosmetic and personal care manufacturers developing long-lasting hydration and texture-enhancing skincare systems. Crosslinking type, water retention profile, dispersion behavior, particle condition, pH, and formulation suitability can be reviewed before sample testing or bulk order confirmation.
Compared with conventional sodium hyaluronate powders, sodium hyaluronate crosspolymer provides formulators with an alternative HA structure for developing customized skincare systems where texture, formulation characteristics and ingredient performance are important considerations.
We provide technical documentation including COA, TDS and SDS/MSDS to support cosmetic manufacturers and ingredient buyers during product evaluation.
- Crosslinked sodium hyaluronate option for advanced moisturizing, film-forming, and texture-support formulations.
- Suitable for serums, essences, gels, creams, masks, leave-on skincare, and premium hydration systems.
- Specification review includes appearance, crosspolymer type, HA basis, dispersion behavior, pH, moisture, and microbiological limits.
- COA, SDS/MSDS, TDS/spec sheet, sample support, and export documents available.

Product Overview
Sodium Hyaluronate Crosspolymer is a modified hyaluronic acid ingredient developed for cosmetic formulators seeking specialized HA systems beyond conventional sodium hyaluronate grades.
Unlike standard low molecular weight or high molecular weight sodium hyaluronate powders, crosspolymer technology provides formulators with a different ingredient structure for designing advanced skincare formulations where texture, formulation characteristics and product positioning are important.
Lifeworth supplies sodium hyaluronate crosspolymer with technical documentation support for cosmetic manufacturers and international ingredient buyers.
For customers requiring conventional sodium hyaluronate powders with different molecular weight options, please refer to our Hyaluronic Acid Bulk product page.
For lightweight cosmetic formulations requiring specific molecular weight characteristics, please explore our Low Molecular Weight Hyaluronic Acid product.
For formulations requiring higher viscosity contribution and texture control, please refer to our High Molecular Weight Hyaluronic Acid product.

Applications
Premium Skincare Formulations:
Sodium hyaluronate crosspolymer is used in advanced skincare formulations where formulators require specialized HA ingredients and unique texture characteristics.
Creams and Gel Systems:
Suitable for cosmetic systems where formulation structure, sensory profile and ingredient performance are important considerations.
Customized Cosmetic Development:
Used by cosmetic manufacturers developing differentiated skincare products with specialized ingredient systems.
How to Choose the Right Grade / Form
For Long-Lasting Hydration Systems
Choose sodium hyaluronate crosspolymer when the formulation needs stronger moisture-retention positioning and a smoother film-like skin feel compared with standard HA powder. The actual performance should be verified in the finished formulation.
For Gel and Mask Formulations
Choose a grade that disperses well and supports the target texture, clarity, tackiness, and hydration profile. Mask and gel systems should be tested with the full humectant, thickener, preservative, and active system.
For Cream and Emulsion Systems
Choose a specification compatible with emulsifiers, oils, thickeners, and processing conditions. Emulsion systems should be evaluated for stability, viscosity, pH, and final sensory performance.
For Multi-HA Formulations
When combining crosspolymer HA with high and low molecular weight HA, select the ratio according to the target hydration story, texture, film-forming effect, and application format. Pilot testing is recommended before commercial confirmation.
Review INCI and Crosspolymer Type
Different crosslinked HA ingredients may have different INCI names, crosslinking routes, and regulatory review requirements. Buyers should confirm the exact INCI name, technical specification, and destination-market suitability before commercial use.
Review Dispersion and Formula Compatibility
Dispersion behavior affects texture, processing, appearance, and finished product stability. The selected grade should be tested in the actual serum, gel, mask, cream, or emulsion system.
Review QC and Documentation Scope
Important sourcing review points include appearance, identification, HA basis, pH, moisture, particle condition, heavy metals, microbial limits, and batch documents. COA, SDS/MSDS, and TDS/spec sheet can be reviewed before order confirmation.
Technical & Formulation Notes
Technical Notes
Sodium hyaluronate crosspolymer is a modified form of hyaluronic acid designed for cosmetic formulation applications.
Compared with conventional sodium hyaluronate grades categorized mainly by molecular weight, crosspolymer materials are evaluated based on their modified structure, formulation behavior and intended application requirements.
Product selection should consider:
• Target product format
• Desired texture characteristics
• Formulation system
• Compatibility with other ingredients
• Technical specification requirements
Manufacturing & Process
HA fermentation → purification → modification/crosslinking process → drying → milling → quality control → packaging.
Manufacturing parameters are controlled to maintain product consistency and meet defined cosmetic ingredient specifications.
Compatibility / Formulation Notes
Ingredient selection:
Sodium hyaluronate crosspolymer should be selected according to formulation objectives rather than treated as a direct replacement for conventional sodium hyaluronate powder.
Key considerations include:
• Desired product texture
• Formulation system
• Compatibility with other ingredients
• Target product positioning
• Technical requirements
For customers comparing different HA ingredient options, Lifeworth can provide technical information to support product selection.
