QUEST-HP

QUEST-HP | Organophosphonate (HEDP) sequestering agent

Product Information

Quest-HP is an organophosphonate (HEDP) based high power sequestering agent specially developed for scouring as well as bleaching of cotton, terry towel and polyester/cellulosic blends. It has a high chelating action for calcium, magnesium and iron under alkaline conditions and high temperature. It not only prevents precipitation of insoluble hydroxides and carbonates formed during scouring and bleaching, but also chelates iron impurities thereby preventing catalytic damage and pin-hole marks during peroxide bleaching. It is also suitable for combine scouring and bleaching operation.

Key Features & Benefits

Key Features	Benefits
High chelation value for calcium and iron	Suitable for processing with hard water and with high iron content
Good sequestering action over wide pH	Suitable for scouring and bleaching Suitable for continuous process application

General Characteristics

Physical appearance	Colourless liquid
Ionic nature	Nonionic to weakly anionic
pH of 1% solution	2 +/- 1
Miscibility	Miscible with water
Compatibility	Compatible with nonionic and anionic products
Stability	Stable to dilute acids, dilute alkalies and hard water

Application

1. In scouring, bleaching as well as combined scouring and bleaching of cotton and blends by batch process:

0.5-1 g/l Quest-HP can be added with usual recipe to prevent
white deposits as well as pin-hole marks due to iron. When
Quest-HP is added in the recipe, reduces the concentration of
organic stabiliser as it has stabilising action.

2. For combined scouring and bleaching on continuous bleaching range

3. In bioscouring of cotton

0.3-0.5% Quest-HP is recommended to prevent precipitation of pectin residues at the end of bio-scouring and before peroxide bleaching. Quantity of peroxide stabiliser can be reduced when Quest-HP is added before bleaching.

Note :

Please note that for dosing, 10% dilution of Quest-HP is recommended instead of neat solution.

Precautions

Storage : Store in cool, ventilated shed away from heat and direct sunlight. Storage temperature should not exceed 35 deg C.Close lids firmly to avoid contact with air and moisture.

Shelf Life : 9 months from the date of manufacturing, if stored under controlled conditions.
