Sodium Hyaluronate Crosspolymer
INCI Name: Sodium Hyaluronate Crosspolymer
CAS No.: 105524-32-1
CroHA® is a cross-linked polymer obtained by cross-linking sodium hyaluronate technology.
It has a dense network structure. The cross-linking reaction causes the macromolecule sodium hyaluronate to be highly aggregated and folded locally, which can combine with more water molecules to achieve film formation, hydration and protection on the skin surface; it has multiple functions such as scavenging free radicals, long-lasting moisturizing, and improving the skin barrier. . The cross-linked sodium hyaluronate not only increases the relative molecular weight, but also increases the volume, thereby forming a network structure. At the same time, it retains the original physical and chemical properties of sodium hyaluronate, and has low toxicity and biocompatibility. Good and resistant to hyaluronidase degradation.
☑ Improve skin barrier
☑ Reduce water loss in the stratum corneum
☑ Resist UV intrusion
☑ Maintain multiple times of moisture
☑ Form a strong surface protective film
