Cross-linked sodium hyaluronate gel - high-density three-dimensional cross-linked network forming material.
Crosslinked Sodium Hyaluronate Gel (Medical Grade) / Adopts Multi-BDDE Crosslinking Technology
High-performance hyaluronic acid gel produced by long-term retention, precise shape support, and medical-grade cross-linking technology.
Crosslinked Sodium Hyaluronate Gel is a high-performance gel material that forms a uniform and stable three-dimensional network structure through a multiple crosslinking technique using BDDE. The degree of crosslinking is precisely controlled within the range of 6-8%, allowing for customization according to specific applications. The high-density crosslinked structure exhibits excellent viscoelasticity, prolonged in-body retention, and shape retention, with a durability expected to last from 6 to 18 months. The residual BDDE level is <1 μg/mL, and the endotoxin levels are strictly managed, ensuring quality that meets medical-grade safety requirements. A variety of grades are available, with viscoelasticity and particle size adjusted for different applications from superficial to deep layers, accommodating diverse formulation and research needs through designed layered characteristics. The superficial grade offers flexibility suitable for delicate linear areas, the mid-layer grade provides natural volume formation, and the deep-layer grade ensures support and stability necessary for three-dimensional shaping. This gel boasts high biocompatibility, excellent hydration capacity, and maintains a stable gel structure, fulfilling both functional and morphological roles. It is suitable for a wide range of applications, including medical aesthetics, viscoelastic supplementation, and anti-adhesion applications in minimally invasive fields.

Applications/Examples of results
Cross-linked sodium hyaluronate gel leverages its high viscoelasticity and stability from a three-dimensional cross-linked network, making it useful in various fields of research and product development. Shallow-layer gels are suitable for applications requiring homogeneity and flexibility in delicate linear areas, while mid-layer types are used in research for natural volume formation and lip-related products. Deep and ultra-deep types are employed in contour design for the entire face, viscoelastic control of large-volume gels, and design research for highly supportive structures. The gel structure, with controlled density and elasticity, is also suitable for evaluations in materials science, such as viscoelastic measurements, safety assessments, flow property analyses, and stress relaxation behavior studies. Additionally, it is adopted as a base material for gel formulations that require hydration retention and moderate viscosity in various research institutions and OEM/ODM manufacturers. The production system and stable supply capability that comply with international standards have been recognized, leading to a wide range of achievements in viscoelastic supplements, materials for minimally invasive fields, anti-adhesion research materials, three-dimensional gel structure development, and biomaterial applications. Custom designs for cross-linking degree, particle size, and viscoelasticity are also available, enabling the construction of optimal physical properties tailored to product concepts.
