  • Pasteing of Disperse dyes
  • Solubilizing Acid and Direct dyes



As a dispersant for Disperse dyes, add at the rate of 5% – 10% of weight of dye to promote rapid wetting and dispersion when pasting dyes with water.   Avoid temperatures over 160°F (71°C).

To solubilize Acid and Direct dyes, add at a rate of 3.5% – 6.5% of weight of dye to improve wetting and solubility while boiling up dye solution. Do not use in conjunction with Basic/Cationic dyes.


Protect from high humidity.
