Mechanism

etrasodium Glutamate Diacetate (GLDA-Na₄) forms stable and soluble chelate complexes with various metal ions through its multiple carboxyl and amino functional groups, effectively sequestering heavy metals and transition metal ions.

It inhibits metal ion-induced oxidation, precipitation, and various catalytic side reactions. After completing metal chelation, the bio-based molecular structure of this substance supports rapid biodegradation, avoiding long-term environmental persistence unlike traditional chelating agents such as EDTA.

🧴 Household & Industrial Detergents

GLDA (Tetrasodium Glutamate Diacetate) is a bio-based, readily biodegradable chelating agent that serves as a sustainable alternative to traditional phosphates and EDTA in detergent formulations. It exhibits outstanding calcium and magnesium sequestration performance, effectively softening hard water, restoring surfactant activity, improving stain removal and preventing soil redeposition. Its excellent compatibility with enzymes, bleaches and surfactants, plus high solubility, makes it ideal for concentrated liquid laundry detergents, automatic dishwashing gels and heavy-duty industrial cleaners. Derived from L-glutamic acid, it meets strict eco-label requirements without compromising cleaning performance.

👗 Textile Printing & Dyeing

In the textile industry, GLDA works as an eco-friendly complexing agent for dyeing, finishing and peroxide bleaching. It scavenges calcium, magnesium and trace metal impurities in process water, avoiding interference with dye uptake and ensuring consistent shade, bright color and good color fastness. It stabilizes hydrogen peroxide during bleaching, protecting fibers from oxidative degradation. Its broad pH tolerance, low toxicity and bio-based origin fit well with the textile industry’s shift toward sustainable, low-impact manufacturing.

🌱 Agriculture & Micronutrient Fertilizers

GLDA is widely used as a chelating carrier for micronutrient fertilizers, including Fe-GLDA, Zn-GLDA and Mn-GLDA. It keeps trace nutrients soluble and bioavailable for plant uptake, even in calcareous, high-alkaline soils where many conventional chelates precipitate out. It helps prevent chlorosis and nutrient deficiency and supports steady crop development. After nutrient delivery, GLDA biodegrades naturally in soil, avoiding long-term accumulation of synthetic chelates.

Personal Care & Cosmetics

GLDA is a mild, skin-friendly chelator formulated into shampoos, body washes, facial cleansers and leave-on skincare products. It binds calcium and magnesium from tap water to preserve foam, reduce mineral deposition on hair and skin, and maintain formulation clarity. It suppresses metal-ion triggered oxidation of fragrances, oils and active ingredients, extending shelf stability. With low irritation risk, good biodegradability and bio-based sourcing, it is popular for clean beauty, baby care and sensitive-skin formulations.
