REAX 81A is the sodium salt of sulfonated modified kraft lignin. It is used in a broad range of dye applications where grinding efficiency and good heat stability are required. It is also used in dry and water-based agricultural formulations.

REAX 85A is the sodium salt of a chemically modified medium molecular weight kraft lignin polymer. It is a primary dispersant in disperse dye formulations where heat and storage stability are required.

REAX 910 is a medium-sulfonated kraft lignin dispersant featuring low free electrolyte content, low conductivity and near neutral pH. This combination of properties makes REAX 910 suitable in liquid dispersion systems where free electrolytes tend to promote gelation and agglomeration of the suspended material.

REAX LS is the sodium salt of a chemically modified, medium molecular weight kraft lignin polymer. It is a primary dispersant in disperse dye and agricultural chemical systems where a combination of excellent heat stability, storage stability and low fabric stain are required.
