Methylglycine N,N-diacetic acid, Trisodium Salt
Environmentally Friendly Chelating Agent

CAS No.: 164462-16-2

Molecular Formula: C7H8NNa3O6                    Molecular weight: 271.11         

Structural Formula:

Property and Usage:

Green chelating agent MGDA.Na3 as chelating agent, is applicable to a variety of fields. Meanwhile, it has excellent toxicological safety property and stable biodegradability.

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 work as substitute for salts of phosphonates, NTA, EDTA, citrate and the other chelating agents in detergent.

MGDA.Na3 is a stablizer for sodium perborate and sodium percarbonate and effective builder in non-phosphor detergent formulation. MGDA.Na3 was proofed as high-efficiency bleaching and stubborn strains removing ability in commercial non-phosphor dishwashing formulations.

MGDA.Na3 has wonderful clean ability in high efficiency washing powder, washing liquid and soap detergent, e.g. after adding MGDA.Na3 into various soaps, it has the effect to prevent rancidity, color change and dirt precipitation.

MGDA.Na3 is used as scale remover and scale inhibitor to prevent scale formulation and soften water, which can also resolve metal salts and hydroxide to clean indissolvable salt scales in various industries.
