Sodium hyaluronate cross-linked polymer high moisture retention and film-forming cosmetic grade ingredient
Crosslinked Sodium Hyaluronate Polymer / High-Functionality Crosslinked Hyaluronic Acid Polymer for Cosmetics Brand
High-density three-dimensional network achieves long-lasting moisture retention and protection. A highly functional cross-linked hyaluronic acid polymer that excels in film formation, moisture retention, and texture enhancement.
Sodium hyaluronate cross-linked polymer is a high-performance polymer material that has been three-dimensionally networked through cross-linking technology from hyaluronic acid (hyaluronan). The cross-linking reaction forms stable bonds between molecular chains, imparting higher moisture retention, film-forming ability, and durability compared to regular hyaluronic acid. The cross-linked structure retains a large amount of moisture while forming a uniform moisture film on the skin's surface, providing long-lasting moisture retention and a comfortable protective function. It also contributes to the reduction of discomfort associated with dryness after sunburn and supports a barrier against external stress. Due to its cross-linked structure, it demonstrates excellent dispersibility in both aqueous and oil-based formulations and can also be utilized as a carrier for active ingredients. Its property of transforming from a solution to a gel makes it suitable for adjusting the viscosity of formulations and improving texture, contributing to an enhanced user experience in cosmetics. This material can be used in a wide range of fields, including cosmetics, skincare, hair care, oral care, sun care, and nail and lip products. Manufacturing is conducted in factories that comply with international standards such as ISO9001, ISO14001, ISO13485, CGMP, HACCP, and FSSC22000, ensuring a high-quality and stable supply of raw materials.

Applications/Examples of results
Sodium hyaluronate cross-linked polymer is utilized across various cosmetic categories due to its excellent moisture retention and film-forming properties. Typical applications include long-lasting hydration, skin protection, and texture enhancement in skincare products such as lotions, emulsions, serums, and creams. It is particularly valued in anti-aging products for its ability to create an elastic moisture film that reduces the sensation of dryness and maintains a moist finish. In the hair care domain, a thin protective film formed on the hair surface imparts shine and manageability while reducing dryness and friction damage. In facial cleansers, it improves foam quality; in oral care, it provides moisture; and it is also used in nail and lip products for moisture retention and shine enhancement. In sun care products, it acts as a moisture-retaining film to prevent dryness, and it can also be applied in handmade soaps and various base formulations. With its high dispersibility and stability, it is easy to handle in a wide range of formulations, both aqueous and oily, and has a proven track record as a carrier for active ingredients. This raw material is adopted by skincare manufacturers both domestically and internationally, salon brands, and OEM/ODM factories, contributing to the development of a wide range of products as a high-performance moisturizing ingredient.
