Our Chelation Agents / Sequestering Agents: Novaquest 6010, Quest, Quest DBSA, HEDP, EDTA, DTPA, Polyquest-700, Polyquest-1200, Quest-WS.

Sequestering agents are products that are essentially used in controlling metal impurities in various media such as water and in many processes such as in manufacture of paper, textiles, leather, soaps and detergents etc.

The hardness of water is basically due to the presence of minerals like calcium & magnesium salts. The role of the sequestering agent is to inactivate these metal ions. In the bargain the water regains its original properties as soft water and can be used freely in any of the processes it needs to be used without the side effects of the contaminant metal ions in solution.

Besides softening of water, sequestering agents are also very helpful in controlling heavy metal ions like iron, lead and other impurities from contaminating various chemical formulations and processes.

The sequestering agents generally find application in the following areas:

• Textile Processing
• Leather Processing
• Paper Manufacture
• Soaps & Detergent Manufacture
• Cosmetics & Personal Care products
• Chemical Industry
• Water Treatment Applications

The Sequestering Agents that we make are those that find application in each of the industries specified above.

List of sequestering agents and textile sequester chemicals :

1. Novaquest-DMS: A high-powered demineraliser used for removal of heavy metal impurities like Fe & Cu. Very useful in pre-treatment of cotton fabric, knits, yarn & woven. Enhances brightness and whiteness of bleached substrate more..
    
2. Novaquest-6010: Novaquest-6010 is highly recommended for use in the processing of cotton, polyester and their blends. Dosage in each case ranges from 1 – 3 gpl of the quantity of water used in the process. However the actual dosage depends on the hardness of the water that needs to be softened more..
    
3. Quest: Improves stabilization of the peroxide by virtue of its dispersing and anticatalytical effects. This is demonstrated by the better degree of whiteness and the better absorptive of the treated textile material. Quest is used preferably in cases where relatively heavily soiled cotton that has not been properly pre cleaned passes into the peroxide bleach more..
    
4. Polyquest-1200: Very effective for controlling, water hardness & heavy metal ions. Improves the washing and soil suspending properties of surfactants. Facilitates dissolving of dyestuffs. Prevents deposits from forming  on the surface of the substrate. Prevents staining due to iron that may be present in the process water. Enables obtain brighter & reproducible dyeing more..
    
5. Quest-DBSA: An excellent sequestering agent which is good for controlling iron and calcium, good anti-redepositing agent for soils in the scouring bath & unfixed dyes in the dye bath, good soaping off agent in the washing off stage. Enhances brightness and whiteness of bleached substrate. Improves colour yield, better colour value & better depth in the shade, helping savings of dye, besides giving better leveling effect during dyeing. The soaping efficiency is much improved enhancing the wet rub fastness and reduction in staining. Another key advantage is its very high tolerance to water of very high hardness more..
    
6. Polyquest-700: Very effective for controlling, water hardness ions. Improves the washing and soil suspending properties of surfactants. Facilitates dissolving of dyestuffs. Prevents deposits from forming on the surface of the substrate. Enables to obtain brighter & reproducible dyeing more..
    
7. Novaquest-FSA: Novaquest-FSA is highly recommended for use in the scouring bath during pre-treatment. It facilitates the removal of heavy metal ions. The dosage recommended is 1.0 to 3.0 gpl depending upon the process employed, whether batch or continuous more..
