Hyasmile® Sodium Hyaluronate Crosspolymer

Hyasmile® Sodium Hyaluronate Crosspolymer is a colorless, clear, viscous, water-soluble cross-linked sodium hyaluronate designed for advanced cosmetic formulations.

Through cross-linking, linear HA chains are transformed into a dense three-dimensional network that binds more water molecules, leaves skin feeling smooth and elastic, and forms a long-lasting biological protective film on the skin surface.

This 3D network evenly covers the skin, enhances the skin barrier, reduces water loss, and helps defend against external aggressors such as UV rays, dust and haze.

Compared with conventional sodium hyaluronate, the cross-linked polymer shows higher resistance to hyaluronidase and degrades more slowly, making the protective hydration film more durable.

It is suitable for use at 0.1–2% in skin care, cleansing and hair care products that require long-lasting moisturization and barrier support.
