||A weakly cationic agent in water used to increase dye penetration and levelness of dyes. Promotes dye penetration and levelness when added just before the dye feed in the same bath. Reduces dye stratification when diluted with water and mixed with dyes in solution prior to the drum addition. Some dyes in combination ordinarily have varying properties and thus different penetration rates which can be greatly minimized when used in conjunction with CHEMOL® 404. High amounts of CHEMOL® 404 can be used to remove dye from the leather.
