What is GLDA-4Na with CAS 51981-21-6?
N,N-BIS(CARBOXYMETHYL)-L-GLUTAMIC ACID TETRASODIUM SALT (GLDA-4Na) is a light yellow transparent liquid. It is also known as tetrasodium glutamic acid dicarboxymethyl. Its chemical name is N.N-bis(carboxymethyl)-L-glutamic acid tetrasodium salt. It is a new green chelating agent that is biodegradable and can be used to replace ethylenediaminetetraacetic acid (EDTA), diethyltriaminepentaacetic acid (DTPA), nitrogen traditional chelating agents such as NTA.

Application
Softens hard water, preventing calcium and magnesium ions from affecting the cleaning efficiency of surfactants, protects the activity of enzymes (such as proteases and lipases), and extends product shelf life. As a naturally derived chelating agent, it replaces EDTA, stabilizing formulas to prevent oil rancidity and oxidative discoloration, extending product life. It is used in boiler and cooling water systems to prevent scaling and deposition.
GLDA-4NA is a metal ion chelating agent that can form stable water-soluble complexes with calcium, magnesium and other ions. Its cleaning and decontamination capabilities are better than those of phosphates, citrates, etc. With its strong detergency, high temperature resistance, non-ecotoxicity, and easy degradation, tetrasodium glutamic acid diacetate is widely used in cleaning agents, detergents, water treatment agents, papermaking auxiliaries, textile auxiliaries, cosmetics, and care products. supplies, aquaculture, metal surface treatment and other fields.
Key Features
1. Excellent environmental performance and biodegradability.
2. Excellent chelating performance, especially suitable for low-temperature washing.
Package
250KG/DRUM or IBC or requirement of clients.
