Applications

  1. Chemical & Dye Industry: Serves as dye intermediate and organic synthesis reagent, improving dye solubility in dye liquor and enhancing dyeing uniformity.
  2. Detergent & Cleaning Industry: Used as an auxiliary in detergent formulations to reduce slurry viscosity, improve fluidity and boost detergency. Note that it differs slightly from sodium dodecylbenzenesulfonate, the main ingredient of most laundry powders.
  3. Foundry & Agriculture: Acts as slurry conditioner in foundry to cut dust pollution; functions as pesticide auxiliary in agriculture to strengthen dispersion and adhesion of pesticides.
  4. Other Fields: Applied as pharmaceutical synthesis intermediate, paper sizing agent raw material and electroplating bath additive to optimize electroplating performance.

Packaging

Paper-plastic composite bags lined with plastic film, net weight 25 kg per bag; customized packaging available upon customer request.

Storage & Transportation
