Archroma celebrates 3 years of working
with aniline-free Indigo heroes
Archroma, a global leader in specialty chemicals
towards sustainable solutions, celebrates nearly three years of
successfully converting the denim industry to aniline-free(1)
pre-reduced liquid indigo. Archroma launched its aniline-free(1)
Denisol® Pure Indigo in May 2018(3).
Archroma has built a very strong reputation
as a leader in developing innovations and solutions that help
make its industry more sustainable.
The Company calls its vision and
commitment: “The Archroma Way to a Sustainable World: Safe,
efficient, enhanced, it’s our nature.”
Aniline is a key ingredient to make the
indigo molecule. Unfortunately, during this process some aniline
impurities are carried through into the indigo dyestuff. When
the indigo is dyed on the fabric, a lot of the aniline impurity
is locked into the pigment in the fabric. The remainder of the
aniline impurity, approximately 300 metric tons annually, 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 new Denisol® Pure Indigo 30 liq was
therefore developed as an aniline-free(1) indigo solution for
designers, manufacturers and brand owners who long for authentic
Since the launch of Denisol® Pure Indigo,
several denim manufacturers, such as front-runner Absolute
Denim, as well as Advance Denim, Azgard 9, Kilim Group, Nuevo
Mundo, Rantex, Shasha Denim and Tuong Long, have taken the
matter in their hands and converted their production or
dedicated lines to aniline-free denim to brands and retailers.
The innovation is also supported by denim
partners such as Be Disobedient and The Denim Window.
Almost 3 years later, Archroma and its
partners can pause and proudly look back to all the aniline they
have removed -together- from the market, thus preserving the
health of many denim workers and the aquatic life in our rivers.
Archroma evaluates that, based on the total
quantity of Denisol® Pure Indigo sold until its introduction,
its partners helped remove almost 18 metric tons of aniline from
the denim supply chain. That represents an equivalent to about
300’000’000 pairs of jeans free of aniline and more than 18’000
garment workers protected from its toxicity(2).
(1) Below limits of detection according to industry standards
(tested & proven).
(2) Based on 15 minutes of work to produce one pair of jeans,
produced over 8-hour working days and 300 working weeks per
“Aniline is a key ingredient of indigo,
says Heike van de Kerkhof, CEO at Archroma. “Because of the
toxicity of aniline, we really wanted to do something about it –
although we initially faced some resistance as not everyone was
ready to shed light on the issue of aniline, especially in the
indigo industry. That is why we are so grateful to the many
like-minded denim partners who decided to take the hand we were
offering with Denisol® Pure Indigo.”
