GLDA.4Na; Tetrasodium Dicarboxymethyl Glutamate
20MT for 250kgs drum or 25MT for 1250kgs IBC
GLDA.4Na
Content: 38%, 47%
Introduction
Tetrasodium Glutamate Diacetate, also known as Tetrasodium Dicarboxymethyl
Glutamate, GLDA-Na4 for short. GLDA-Na4 is a new type of green degradable chelating agent, can replace traditional phosphonates, EDTA, NTA. The product is suit for a wide pH range, with high solubility, high temperature resistance, strong detergency, no ecological toxicity, has synergistic
effect with fungicides, and no irritation to skin and eyes.
Specification
Item | Specification |
Appearance | Light yellow viscous liquid |
Active matter content | 47%, 38% |
PH value | 10.0-12.0 |
NTA | ≤0.10% |
Density (@20℃)， | ≥1.2g/cm3 |
Application
It is suitable for cleaning agents, detergents, textile auxiliaries, daily chemicals, oilfield water treatment, pulp and paper auxiliaries, metal surface treatment, etc.
Property & Advantage
1. High solubility under wide pH
GLDA has good solubility in strong acid to high alkali systems, and has better advantages for formulating high active ingredients and low water content formulation systems. For example, 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
By thermogravimetric analysis, GLDA is tested at 170°C for 6 hours or at 150°C for a week. GLDA has no decomposition and is extremely stable. Compared with other chelating agent products at 100°C, it has the best performance.
3. Strong chelating ability
For the formulation, it is very important to choose a chelating agent with sufficient chelating ability. The chelating ability is related to different metal ions and the pH value of the system. For the binding force of a specific metal, we can see it from the stability equilibrium constant. GLDA has a good effect on all kinds of difficult-to-clean calcium scales or difficult-to-clean equipment.
4 Has the effect of antiseptic and synergistic
Because GLDA has natural amino acid components, it has a stronger binding ability with animal cell walls, which can effectively destroy the electrolyte balance of cells, inhibit cell activity, and thus play a role in antiseptic and synergistic. After experiments, we found that GLDA has obvious antiseptic and sterilization synergies in many fungicides, which can save 20%-80% of the usage. For example, we use the preservative-imidazolidinyl urea and GLDA compound to observe its bactericidal effect on Pseudomonas aeruginosa, and it turns out that after compounding with GLDA, the usage can be reduced by 50%.
Packing and Storage
Packing In 25kgs, 250kgs, 1250kgs drums.
Storage Store in cool place. Sealed and stored in a dry and ventilated warehouse, avoid mixed storage with acidic and odorous items, prevent exposure to the sun and rain.
