Sodium Hyaluronate Crosspolymer

Product Description

Sodium Hyaluronate Crosspolymer is a high-purity crosslinked hyaluronic acid derivative supplied for cosmetic and personal care formulations. It is designed for manufacturers seeking advanced moisture retention, skin conditioning, and long-lasting hydration performance in topical products.

Its crosslinked polymer network provides strong water-binding capability and forms a hydrated film on the skin. Compared with conventional linear sodium hyaluronate, the crosslinked structure can provide more persistent hydration and improved resistance to enzymatic degradation. This makes it suitable for formulations targeting sustained moisturization, skin smoothness, and barrier-supportive care.

Sodium Hyaluronate Crosspolymer is increasingly used in premium skincare formulations, including moisturizing creams, serums, gels, masks, and anti-aging products. Direct factory supply enables bulk buyers to obtain consistent cosmetic-grade raw material with flexible specifications for formulation development.

Key Benefits & Applications

Sodium Hyaluronate Crosspolymer provides advanced hydration and skin-conditioning performance for cosmetic formulations requiring durable moisture retention and a smooth skin feel.

• Long-Lasting Hydration: Crosslinked hyaluronate forms a hydrated polymer network that supports sustained moisture retention on the skin.
• High Water-Binding Capacity: Helps maintain hydration within topical formulations and contributes to a moisturized skin feel.
• Skin Conditioning: Supports smoother, softer-feeling skin and a comfortable after-feel.
• Protective Film Formation: Forms a flexible hydrated film that can help reduce moisture loss from the skin surface.
• Premium Skincare Applications: Suitable for moisturizing serums, facial creams, gels, masks, anti-aging formulations, and barrier-focused skincare products.

Formulation Guidelines

Sodium Hyaluronate Crosspolymer should be gradually dispersed and adequately hydrated in the appropriate formulation phase. Because crosslinked hyaluronate forms a three-dimensional hydrated network, sufficient hydration time and gentle mixing are recommended for uniform dispersion and optimal sensory performance.

• Disperse gradually under suitable agitation to minimize aggregation and ensure uniform hydration.
• Allow sufficient hydration time before evaluating the final viscosity, texture, and hydration performance.
• Optimize the concentration according to the desired skin feel, film-forming properties, and hydration profile.
• Evaluate compatibility with electrolytes, surfactants, preservatives, and other polymers because formulation composition can affect swelling and rheological behavior.
• For advanced moisturizing formulations, assess water retention, viscosity, physical stability, and sensory performance during formulation and stability testing.
• Combine with Sodium Hyaluronate for complementary hydration across different molecular and structural forms of hyaluronic acid.
