Structural formula:

 

1. Product performance

Sodium polyaspartate, non-phosphorus, non-toxic, non-pollution and completely biodegradable, is an environmentally friendly chemical and belongs to a class of polyamino acids. The peptide bond on the main chain of the structure is easily broken by the action of fungi, microorganisms, etc., and is finally degraded into water and carbon dioxide that are harmless to the environment, which is safe and reliable.

Sodium polyaspartate is highly hydrophilic and water-soluble, and can form a breathable protective film. In addition, it has a highly efficient water-locking and moisturizing function, which can improve skin moisture and make the skin feel smooth and refreshed. It can also replenish skin nutrition, improve skin fullness and elasticity, and can tighten the skin and reduce wrinkles.
