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.

Specification:

Character:

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.

The typical chelating values are as follows:

60 mg Ca²⁺/g MGDA.Na₃,

95 mg Cu²⁺/g MGDA.Na₃,
