Break new ground with aniline-free* indigo for denim.

Archroma’s new aniline-free* indigo dye, Denisol® Pure Indigo 30 liq, reduces risk when producing the traditional, iconic indigo blue that consumers associate with denim and jeans.

During production, some of the aniline stays locked into the indigo pigment and is difficult to wash off the fabric. The remainder of the aniline impurity, approximately 300 metric tons, is discharged during dyeing. This can be an issue as aniline is toxic to aquatic life. In addition, exposure levels to factory workers can be high.

The toxic chemical is therefore starting to feature on the restricted substance lists (RSL) of some major clothing brands and retailers.

For designers and brand owners who long for authentic indigo inspiration, the new Denisol® Pure Indigo 30 liq now also makes it possible to produce indigo-dyed denim without high
levels aniline impurities.

From fiber to finish, Archroma offers a scope of possibilities for effects and colors, from the authentic roots of indigo to the most innovative and eco-advanced solutions.
