Household chemical application

Yuanlian company Tetrasodium glutamate diacetate (GLDA-Na), trisodium methylglycine diacetate (MGDA-Na), tetrasodium aspartate diacetate (ASDA-Na), tetrasodium iminodisuccinate (IDS-Na), as environmentally friendly chelating agents, can replace EDTA, DTPA, organic phosphonic acid chelating agents.

Green phosphorus-free chelating agents, as builder, can prevent liquid soap from forming soap scales after multiple washings, stabilize fatty acids, are ideal additives for liquid soap, soap-based laundry powder, etc., can enhance products’ decontamination ability and easy bleaching property, reduce the irritation of products.

Green chelating agents, can chelate iron, copper and other metal ions, in bleaching process they can stabilize peroxides such as hydrogen peroxide and hydrogen peroxide , protect fiber and improve whiteness. They can be used as bleach stabilizer for restaurant and hotel linen washing, tablecloth washing, etc.

Environmental friendly chelating agents, can be widely used in washing and cleaning industry, such as household detergent cleaning agents, industrial cleaning agents, dishwasher cleaning agents, laundry detergents, disinfection and hygiene cleaners, car cleaning agents, reverse osmosis membrane cleaning agents, shower and bathtub cleaning agents, production line cleaning agents, pipeline cleaning agents, oil field platform cleaning agents, etc.

1. Features of GLDA-Na4 used in daily chemical detergent auxiliaries:

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%.

2.Usage of MGDA-Na3 in cleaning detergent field

MGDA-Na3 is biodegradable, can improve the cleaning effect of household and industrial detergents and cleaning agents.

1）Fabric detergent

In heavy-duty laundry detergents, liquid laundry detergents and soap-based detergents, MGDA is particularly effective for stubborn stains such as natural oils, sebum, blood stains, milk stains, ink stains, dust and protein.

Detergent that formula contains fatty acids and soap, can easily form soap scales with

calcium and magnesium ions in the water during use, which will deposit on the surface of the fabric, causing sour odor and reducing wettability. MGDA can effectively solve the stains formed by calcium soap and prevent the redeposition of calcium soap.

2）Phosphorus-free dishwasher detergent

After various countries have implemented bans and restrictions on phosphorus,

various phosphorus-replacement additives have appeared. The use of phosphorus-free formulations of automatic dishwashing detergents will cause the filming of detergent and stain removal performance will be decreased, and the use of MGDA will improve this situation.

For stubborn stains, such as starch and protein in food, MGDA has been proven to have efficient rinsing and starch stain removal performance in commercial phosphorus-free dishwashing detergent formulations, especially for tea stains.

3）Cleaning of inorganic deposits

MGDA can convert poorly soluble compounds into water-soluble substances, andhas good solubility for inorganic precipitates, has better effect for old and dry calciumstains.

Cleaning calcium carbonate scale: Use acid (such as hydrochloric acid, citric acid,etc.) to generate carbon dioxide to remove calcium ions, which is not suitable for closed systems and corrosive systems. The use of chelating agents such as MGDA to form soluble complexes to complete this performance without related problems and can prevent formation of new calcium carbonate stains.

Cleaning calcium phosphate scale: For example, during milk processing, insoluble calcium phosphate precipitates are formed, which is not easy to clean. The complexing ability of MGDA on it exceeds other degradable complexing agents.
