Archroma has presented an aniline-free (below limits of detection) denim indigo dye. The brand new dye provides a non-toxic way to produce the traditional, iconic indigo blue that consumers associate with denim and jeans.
Currently, aniline impurities are an unavoidable element of producing indigo-dyed denim. Unlike other chemical impurities, aniline is locked into the indigo pigment during the dyeing process and therefore cannot be washed off the fabric.
Scientific testing has shown that aniline impurities are toxic to humans, causing skin allergies, damage to major organs and genetic defects, as well as being linked to cancer. Aniline is also toxic to aquatic life, which is an issue as two-thirds of the 400 metric tons of aniline waste on an annual basis ends up in the environment as wastewater discharge.
The toxic chemical is, therefore, starting to feature on the restricted substance lists (RSL) of some major clothing brands and retailers.
“At Archroma, we continuously challenge the status quo in the deep belief that we can make our industry sustainable. By removing a hazardous impurity from the denim supply chain, we aim to protect the workers who create denim, the consumers who wear denim, and the environment with cleaner waterways,” said Alexander Wessels, CEO, Archroma
