Structural formula

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.

Usages

1. Phosphorus-free scale and corrosion inhibitor.

Polyaspartic acid PASP as a scale and corrosion inhibitor is widely used in salt industry, oilfield reinjection water, seawater desalination, drilling fluid viscosity reducer, industrial circulating water, boiler water, reverse osmosis water, coal water slurry additives and other water treatments. In high hardness, high alkalinity, high PH, high concentration multiple, and high temperature system, it has excellent performance.

2. Green detergent auxiliaries.

Such as detergent synergists (dishwashing detergent, laundry detergent, industrial washing Agent, etc).

Polyaspartic acid is electrolyte-resistant, alkali-resistant and low-foaming. The role of polyaspartic acid in washing is to soften the water,promote dispersion and anti-fouling, and prevent the oil stains that have been washed away from re-staining. The key point is that PASP is excellent in biodegradation.

3. Agricultural applications.

Used as fertilizer synergist, soil conditioner, wetting agent, nutrient absorption enhancer, promote the absorption of phosphorus by plants, and promote the growth of plant roots. Prevent drip irrigation pipes from scaling, alleviate soil compaction, and improve soil salinity.

In addition, the combined use with pesticides can improve the efficacy.

4.Cosmetics application.

Polyaspartic acid added to cosmetics can moisturize the skin, lock water on the skin, and improve skin elasticity.
