Structural Formula:

Function:

The environmentally friendly chelating agent TH-MG Methylglycine N,N-diacetic Acid Trisodium Salt (MGDA.Na3) is used as a chelating agent and is suitable for various fields, with excellent safety characteristics and stable biological degradability.

As a metal ion chelating agent, MGDA.NA₃ can chelate metal ions to form stable soluble complexes. MGDA.NA₃ can be used in wide pH scope, and create synergistic effect with boicides in the system. MGDA.NA₃ can be used as a substitute for traditional chelating agents such as Phosphonates salts, NTA, EDTA, Citrate and the other chelating agents in detergent. MGDA.NA₃ can act as a stablizer for sodium perborate / sodium percarbonate and effective builder in non-phosphor detergent formulation. MGDA.Na₃ has been proven to have efficient rinsing and stubborn dirt removal performance. MGDA.Na₃ also exhibits excellent cleaning power in high-efficiency laundry detergents, laundry detergents, and soap based detergents, e.g. when added to various types of soap, it can prevent sourness, discoloration, and inhibit dirt deposition. MGDA.NA₃ is used as scale remover and scale inhibitor to prevent scale formulation and soften water, and can also resolve metal salts and hydroxide to clean insoluble salt scales in various industries.

Specification:

Property:

The main character of MGDA.Na3 is excellent chelating ability, which can replace traditional chelating agents. The dosage should be adjusted according to actual application and effects.
