Crosslinked Sodium Hyaluronate (Sodium Hyaluronate Crosspolymer) is a cosmetic-grade hyaluronic acid derivative engineered to form a unique three-dimensional moisture network on the skin. Compared with conventional linear hyaluronic acid, it provides superior moisture retention, prolonged hydration, excellent film-forming properties, and enhanced formulation stability. Manufactured in ISO-certified facilities under strict quality control, each batch is supported by comprehensive quality documentation and a Certificate of Analysis (COA). As a professional manufacturer and supplier of cosmetic-grade hyaluronic acid ingredients, Shoucheng Bio offers reliable bulk supply, customized solutions, and technical support for cosmetic brands worldwide.
Produced in ISO-certified facilities, each batch is accompanied by comprehensive quality documentation and a Certificate of Analysis (COA). The following comparison summarizes structural and performance differences between crosslinked and conventional hyaluronic acid:
Feature | Crosslinked HA | Conventional HA |
|---|---|---|
Structure | 3D network | Linear |
Hydration | Long-lasting | Short-term |
Stability | High | Moderate |
Release | Controlled | Immediate |

Crosslinked sodium hyaluronate serves as a functional ingredient across multiple cosmetic product categories. Commercial formulators incorporate this material into the following applications:
High-end moisturizing creams
Anti-aging skincare products
Gel formulations
Facial masks
Premium serums
The crosslinked structure supports formulation flexibility and is compatible with various cosmetic bases and delivery systems.
Crosslinked sodium hyaluronate forms a gel structure when hydrated. This property contributes to texture and viscosity control in finished products.
The three-dimensional polymer network enables controlled release of moisture over time, supporting prolonged hydration effects on the skin.
The crosslinked matrix exhibits higher stability compared with linear hyaluronic acid, helping maintain product consistency throughout shelf life.
Incorporation into formulations can influence skin feel and spreadability, contributing to the overall sensory profile of the finished product.
We focus on hyaluronic acid production and offer a full range of HA variants, from low-molecular-weight to crosslinked grades, supporting diverse formulation needs.
Each production batch undergoes full testing, with results documented in individual COAs. This supports consistent performance across commercial production runs.
Our HA portfolio includes multiple molecular weight grades and modified forms, allowing commercial procurement teams to source multiple ingredients from a single supplier.
Our technical team provides assistance with formulation development and application questions, supporting product development timelines.
Bulk ordering structures are available for enterprise customers with regular or large-volume requirements.
Minimum order quantities vary by grade and packaging specification. Contact our sales team for specific MOQ details based on your volume requirements.
Yes, samples are available for evaluation purposes. Please submit a request with your company information and intended application to receive sample details.
Products are manufactured in ISO-certified facilities. Each shipment includes a batch-specific Certificate of Analysis. Additional documentation can be requested during the procurement process.
Particle size is available in standard 80 mesh, and customization options exist for certain parameters. Discuss your specific requirements with our technical sales team to evaluate feasibility.
Lead times depend on order volume and current production schedules. Standard inventory items may ship within shorter timeframes, while custom or larger volume orders require advance planning.
