PASP and Its Derivatives
CAS 35608 40 6 and 7320-34-5346 identify potassium polyaspartate, a green and biodegradable polymer derived from polyaspartic acid. Known also as polyaspartic acid potassium salt, this innovative material combines environmental sustainability with high-performance functionality, making it an excellent choice across agricultural, industrial, and food applications.
Potassium of polyaspartic acid/Potassium polyaspartate/Polyaspartic acid potassium salt/KPA
Potassium polyaspartic acid is the potassium salt form of polyaspartic acid, which is a polymer of amino acids containing a large number of amide bonds and carboxyl groups in its molecular chain. These functional groups endow potassium polyaspartic acid with unique chemical properties, which have good water solubility and can quickly dissolve in water to form a clear solution.
The characteristics of its molecular structure make it biocompatible and biodegradable. In natural environments, potassium polyaspartic acid can gradually decompose into small molecules that are harmless to the environment, without causing long-term environmental pollution like some traditional chemically synthesized polymers.
Potassium polyaspartate is the potassium salt form of polyaspartic acid, composed of amino acid-derived polymers rich in amide bonds and carboxyl groups. These functional groups allow it to dissolve easily in water, forming a clear, stable solution.
More importantly, this compound—also referred to as potassium of polyaspartic acid, KPA, or polyaspartic acid potassium salt—is both biocompatible and biodegradable. Unlike traditional synthetic polymers, it decomposes naturally into harmless small molecules, making it a top choice in industries aiming for environmental responsibility.

1)Agriculture – Eco-Friendly Fertilizer Enhancer
In agriculture, potassium polyaspartate functions as a powerful fertilizer additive. It promotes better nutrient absorption in crops like grains, vegetables, fruits, and flowers. Benefits include:
Enhanced resistance to stress and disease
Stronger plant structure and improved crop quality
Increased uptake of micronutrients such as zinc, manganese, and iron
This makes polyaspartic acid potassium salt a sustainable solution for modern farming practices.
2) Industrial – Multi-Functional Water Treatment & Chelation
As a chelator, dispersant, and scale inhibitor, potassium polyaspartate contributes to more efficient industrial operations. It is commonly used in:
Cooling water systems
Boiler descaling
Metal ion chelation
Corrosion prevention
Moisturizing agents in chemical processing
Its performance in harsh chemical environments, paired with excellent biodegradability, makes KPA a reliable and responsible industrial additive.
3)Food – Wine Stabilization Agent
In the food industry, potassium polyaspartate is gaining popularity as a stabilizer in winemaking. It is approved by:
Food Standards Australia and New Zealand (FSANZ) – up to 100 mg/L
Health Canada – permitted at 0.01% concentration
Its primary function is to inhibit crystal formation (e.g., tartrate), improving wine clarity and storage stability.
For liquid form:250kg/drum,or 1250kg/IBC,or as client’s request
For soild form:20kg/bag,or as client’s request.
During use, it is still important to avoid inhaling dust or coming into contact with the skin and eyes. If accidentally touched, rinse immediately with plenty of water.
Due to its strong hygroscopicity, it should be sealed during storage to prevent moisture and clumping, which may affect its performance and effectiveness.
