Product Introduction:

Tetrasodium glutamate diacetate is also called tetrasodium dicarboxymethyl glutamate, N,N-BIS(CARBOXYMETHYL)-L-GLUTAMIC ACID TETRASODIUM SALT, or GLDA-Na4 for short. It is a new type of green degradable chelating agent, phosphorus-free biodegradable, and can replace traditional phosphonates, EDTA and NTA.

The name “GLDA” stands for glutamic acid, sodium (and other salts) diacetate, which means it has two sodium ions (glutamic acid) per molecule. It can occur naturally in the body, but can also be synthesized from glutamine or glutamate precursors such as L-glutamate and L-glutamate precursors.

GLDA-Na4 is a novel glutamate for the food industry, which has been used in the food industry for over 10 years. GLDA-Na4 is completely free of any harmful substances and will not pose any threat to human health. It can be used in various industrial auxiliaries, detergents, etc.

Tetrasodium glutamic acid diacetate products are suitable for a wide pH range, high solubility, high temperature resistance, strong detergency, no ecotoxicity, synergistic effect with fungicides, and no irritation to skin and eyes.

  • Detergent, laundry detergent and other furniture washing care products;
  • Shampoo, shower gel and other washing off products;
  • Hair dye, styling products, wet wipes and other fields.

As Cleaning Agent

Tetrasodium glutamate diacetate (GLDA-Na4) is a compound used in the production of detergents, cleaners and textile auxiliaries. In addition, it also includes many applications in oil field water treatment, pulp and paper auxiliaries, etc.

Tetrasodium glutamate diacetate is a derivative of glutamate. It can be obtained by soaking dried medicinal herbs in water for four weeks before drying them.

Glutamate is the main active ingredient in most commercial cleaners and cleaning products. It is also used to make certain types of medicines, such as antibiotics and anti-inflammatory drugs.

GLDA can be easily found in many of the products we use, such as detergents, cleaners and textile auxiliaries.

Advantages: Tetrasodium glutamate diacetate is easily soluble in water. It has no effect on the pH of the water. It does not contain many impurities such as certain heavy metals, halogens and organic compounds in commonly used compounds (monoamines) and washes off easily when mixed with chemicals.

For The Food Industry

GLDA-Na4 is also used as a food additive to make it taste better. Its use in the food industry has been growing rapidly. This is due to its beneficial effects on human health and safety, low cost and high efficiency.

Tetrasodium glutamate diacetate is a compound used to make food coloring. It helps make food colorings more vibrant and colorful, making them look more appealing to consumers. It can be found in a variety of processed foods, such as sauces, salad dressings, jams, and candies.

GLDA-Na4 is a glutamate that is also used as a preservative in the food industry. The main purpose of GLDA-Na4 is to prevent spoilage and inhibit the growth of spoilage organisms, which prevents food spoilage.

Features and Benefits of GLDA-Na4:

1 High solubility at wide pH

Tetrasodium glutamate diacetate has good solubility in strong acid to high alkali systems, and has better advantages for formulating high active constituents and low water content expression systems. For illustration, in the high alkali system in industrial cleaning, the acid cleaning system and the high concentration system have very good solubility.

2 Good high temperature stability

Through thermogravimetric analysis, GLDA-Na4 was tested at 170 °C for 6 hours or at 150 °C for one week. GLDA didn’t decompose and was extremely stable. Compared with other chelating agent products, the performance was the stylish at 100 °C.

3 Strong chelating capability

For the formulation, it’s veritably important to choose a chelating agent with sufficient chelating capability. The chelating ability is related to different metal ions and the PH value of the system. For the binding force of a specific essence, we can see from the stable equilibrium constant. Tetrasodium glutamate diacetate has a veritably good effect on all kinds of hard-to-clean calcium scale or hard-to-clean outfit.

4 has the effect ofanti-corrosion and community

Because Tetrasodium glutamate diacetate has natural amino acid composition, and has stronger list capability with beast cell wall, it’ll effectively destroy the electrolyte balance of cells, inhibit cell exertion, and therefore play a part of antiseptic and synergistic effect.

After trials, we plant that GLDA has egregiousanti-corrosion and sterilization community in numerous pesticides, which can save 20%-80% of the usage. For illustration, we used the preservative-imidazolidinyl urea and GLDA emulsion to observe its bactericidal effect on Pseudomonas aeruginosa, and plant that after compounding with GLDA-Na4, the usage amount can be reduced by 50%.
