Magnesium polyaspartate/Magnesium of polyaspartic acid/Polyaspartic acid magnesium salt
Magnesium polyaspartate is the magnesium salt form of polyaspartic acid. Polyaspartic acid is a kind of biopolymer, which is polymerized from aspartic acid monomers. Its molecular chains contain a large number of functional groups such as carboxyl groups (-COOH). When these carboxyl groups react with magnesium ions (Mg²⁺) to form ionic bonds, magnesium polyaspartate is obtained. From the perspective of chemical structure, it is a kind of polyamino acid compound with magnesium ions.

1) Chelating ability for metal ions: The polyaspartic acid part in magnesium polyaspartate has a strong chelating effect on metal ions, especially having a close combination with magnesium ions themselves. This chelating effect has important applications in fields such as industry and agriculture. For example, in water treatment, it can chelate metal ions like calcium and magnesium in water to prevent the formation of scale.
2) Biodegradability: It is an environmentally friendly compound. Magnesium polyaspartate can gradually degrade in the natural environment, and its degradation products are mainly non-toxic and harmless small molecular compounds, such as amino acids. It will not accumulate in the environment like some traditional chemical agents and cause long-term pollution.
3) Role in agriculture: As a fertilizer additive, magnesium polyaspartate can slowly release magnesium ions. Magnesium is an important component of plant chlorophyll and can promote the photosynthesis of plants. Meanwhile, the polyaspartic acid part can improve the utilization rate of other nutrient elements (such as nitrogen, phosphorus, potassium, etc.) in fertilizers, enabling plants to absorb and utilize fertilizers better, thus increasing the yield and quality of crops.

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.
