Sodium Hyaluronate Crosspolymer is a crosslinked form of Sodium Hyaluronate and is a specialty cosmetic ingredient used mainly for humectant and skin-conditioning applications. Unlike conventional linear Sodium Hyaluronate, the hyaluronate chains in a crosspolymer are chemically linked to form a three-dimensional polymer network. COSMILE Europe identifies Sodium Hyaluronate Crosspolymer as a humectant and skin-conditioning ingredient.
The crosslinked structure gives the ingredient different physical and formulation properties from ordinary Sodium Hyaluronate. Instead of behaving only as a soluble linear polymer, a crosslinked hyaluronate can form a hydrated network capable of retaining water within the formulation or on the skin surface.
The exact characteristics depend on the crosslinking chemistry, degree of crosslinking, molecular-weight characteristics and particle or gel structure of the commercial grade. Therefore, Sodium Hyaluronate Crosspolymer should be specified according to the exact grade rather than treated as one material with a universal molecular weight.
Sodium Hyaluronate Crosspolymer is a polymeric derivative of hyaluronic acid. The FDA/NCATS substance database identifies Sodium Hyaluronate Crosspolymer-4 as a crosslinked polymer consisting of hyaluronic-acid-derived monomer units and a crosslinker based on 1,4-butanediol diglycidyl ether.
The broader INCI Sodium Hyaluronate Crosspolymer should not automatically be assigned the molecular formula or molecular weight of ordinary Sodium Hyaluronate. Crosslinking changes the polymer architecture, and different crosspolymer grades can use different crosslinking systems.
A CAS identifier should also be treated carefully. Public regulatory records identify 113797-47-0 as a generic family identifier for Sodium Hyaluronate Crosspolymer-4, while other databases may list different identifiers for specific crosslinked structures.
For this reason, the CAS number and exact chemical description should be confirmed against the specific commercial grade supplied to SDP before publishing a definitive CAS identifier.
Sodium Hyaluronate Crosspolymer is primarily a humectant and skin-conditioning cosmetic ingredient. Its crosslinked structure allows it to interact strongly with water and contributes to the moisture-management characteristics of cosmetic formulations.
The crosslinked polymer network can also influence formulation texture, hydration and film-forming behavior. This makes Sodium Hyaluronate Crosspolymer particularly relevant to formulations where formulators want a hyaluronate material with properties different from a conventional linear Sodium Hyaluronate.
The Cosmetic Ingredient Review is evaluating multiple Sodium Hyaluronate Crosspolymer ingredients, including Sodium Hyaluronate Crosspolymer, Crosspolymer-2, Crosspolymer-3, Crosspolymer-4, Crosspolymer-6 and Crosspolymer-7. The review identifies these materials as humectants and skin-conditioning ingredients in cosmetic formulations.
Sodium Hyaluronate Crosspolymer can be considered for a variety of skin-care and personal-care formulations, including moisturising creams, facial serums, gels, lotions, masks and other hydration-focused products.
Its crosslinked structure makes it useful where formulation developers want a hyaluronate-based ingredient with a different hydration and texture profile from conventional Sodium Hyaluronate. It can also contribute to the consistency and sensory properties of suitable gel or emulsion systems.
The ingredient is particularly suitable for water-containing formulations, although the exact dispersion and hydration process depends on the commercial grade. Some crosspolymer materials are supplied as powders, while other commercial systems may contain the crosspolymer pre-dispersed in a carrier.
Because different crosspolymer grades can use different crosslinking chemistries, formulators should follow the technical specifications and recommended processing conditions of the selected grade.
The most important considerations for Sodium Hyaluronate Crosspolymer are crosslinking type, degree of crosslinking, physical form, moisture content and hydration behavior. Unlike conventional Sodium Hyaluronate, a single molecular-weight number is generally not sufficient to describe the performance of a crosslinked polymer.
The Assay (HPLC) field should not be populated with an arbitrary percentage. Crosslinked hyaluronate is a polymeric material, and quality evaluation can involve identification, polymer content, moisture, ash, pH, viscosity or rheological properties, particle characteristics, microbiological quality and other grade-specific parameters.
The exact CAS identifier should also be linked to the specific crosspolymer grade. For example, the FDA/NCATS record for Sodium Hyaluronate Crosspolymer-4 identifies CAS 113797-47-0 as a generic family identifier, while the broader Sodium Hyaluronate Crosspolymer family contains chemically distinct crosslinked materials.
Moisture exposure should be controlled during storage because hyaluronate-based materials can be hygroscopic. The finished formulation should also be tested for compatibility with electrolytes, surfactants, preservatives and other polymers.
Sodium Hyaluronate Crosspolymer is a specialty cosmetic ingredient for manufacturers developing advanced moisturising, hydrating and skin-conditioning products. Its crosslinked polymer architecture provides a formulation option distinct from linear Hyaluronic Acid and Sodium Hyaluronate.
For B2B cosmetic raw-material sourcing, the product specification should clearly identify the exact INCI grade, crosslinking chemistry where applicable, physical form, moisture, pH, viscosity or rheological characteristics and microbiological requirements.
As a Sodium Hyaluronate Crosspolymer Cosmetic Ingredient Manufacturer in India, the focus is on controlled polymer characteristics, consistent raw-material quality and suitability for bulk cosmetic and personal-care formulation requirements.
