Polyaspartic acid potassium salt 40% solution

Potassium polyaspartate is potassium salt of polyaspartic acid.
K-polyaspartate is used as food grade stabiliser against tartrate crystal precipitation (anti-scaling additive) in wine, fertilizer synergist in agriculture.

CAS No.: 64723-18-8
Synomyms:
Polymer of potassium L-aspartate;
L-Aspartic acid, homopolymer, potassium salt;
Polyaspartic acid potassium salt;

Synthesis routes:
There are two common process routes for synthesizing salts of polyaspartic acid.

• First method, maleic anhydride is used as the main raw material. Water treatment grade product is usually produced by this method.
• The other method, food grade aspartic acid is used as the main raw material. This route was chosen for food grade potassium polyaspartate.

In agriculture, Potassium polyaspartate can be used as anti scale deposit and dispersant in irrigation system, and raw material for saline soil improver, fertilizer potentiator. Potassium polyaspartate can promote root growth and enhance stress resistance.
