Main Applications

The Applications of N,N-BIS(CARBOXYMETHYL)-L-GLUTAMIC ACID TETRASODIUM SALT(GLDA-Na4)

1. Water Treatment
In water treatment processes, GLDA-Na4 effectively chelates metal ions like calcium, magnesium, and iron, which can cause scaling and corrosion in pipes and machinery.

  • Water Softening: GLDA-Na4 improves water quality by preventing mineral buildup, which enhances the performance of detergents and cleaning agents.
  • Heavy Metal Removal: It is also used to remove heavy metals, such as lead and mercury, in water purification systems, improving water safety for industrial and municipal applications.

2. Cleaning Products
GLDA-Na4 is an ideal ingredient for eco-friendly cleaning formulations, offering effective metal ion chelation while being biodegradable.

  • Detergents and Industrial Cleaners: It helps increase cleaning efficiency by binding metal ions, which improves the performance of detergents and other cleaning solutions.
  • Greener Cleaning Solutions: It is a safer alternative to conventional chelating agents, making it a perfect choice for companies looking to develop sustainable, non-toxic cleaning products.

3. Agriculture
In agriculture, GLDA-Na4 improves the absorption of essential nutrients by plants and enhances the efficiency of fertilizers and pesticides.

  • Improved Nutrient Uptake: By chelating micronutrients such as iron, zinc, and copper, it ensures better plant growth and healthier crops.
  • Eco-Friendly Fertilizers: It’s an ideal ingredient for developing eco-friendly fertilizers that minimize environmental harm while promoting high agricultural yields.

4. Personal Care & Cosmetics
GLDA-Na4 is used in cosmetics and personal care products to stabilize formulations and prevent metal ion-related degradation.

  • Stabilizing Skincare Products: It helps maintain the stability and effectiveness of cosmetic formulations, such as moisturizers, lotions, and serums.
  • Hair Care Solutions: It is also used in shampoos and conditioners to prevent the buildup of minerals, which can damage hair and affect product performance.
