Sodium Polyaspartate is a phosphorus-free, non-toxic, non-polluting, and fully biodegradable environmentally friendly chemical belonging to the class of polyamino acids. The peptide bonds in its main chain are easily broken down by fungi and microorganisms, ultimately degrading into environmentally harmless water and carbon dioxide, ensuring safety and reliability.
It exhibits high hydrophilicity and water solubility, forming a breathable protective film. Additionally, it offers efficient water-locking and moisturizing functions, enhancing skin hydration and providing a smooth, refreshed feel. It also replenishes skin nutrients, improves skin fullness and elasticity, and helps tighten the skin and reduce wrinkles.
