With a heritage of more than a century in product development and innovation, specialty chemical company DyStar celebrates hard work and notable achievements for indigo excellence in the past 125 years.
The first industrial synthesis of indigo, Indigo Pure BASF, was successfully manufactured and introduced into the market by BASF SE, Ludwigshafen/Germany, in July 1897. It was a significant achievement for the German chemical industry.  
Over the years, the product has made revolutionary changes to the supply chain. New technologies enabled the transformation of synthetic indigo powder application to pre-reduced DyStar Indigo Vat 40% Solution. The pre-reduced solution set an important industry milestone when it was first launched in 1998. The technology transforms Indigo into its soluble Leuco form, making the indigo dyeing process more sustainable, efficient, and stable in production. In addition, workers in denim mills can also be assured of product safety.
Similarly, in recent modules under Cadira Denim, DyStar Singapore Pte. Ltd., Singapore, introduced the first salt-free indigo dyeing process. The applied technology completely eliminates hydrosulfite in the application of indigo.
»DyStar has kept the legacy of indigo innovation alive and will continue to innovate our products in the future.«
Thorsten Huels, Director of DyStar’s Global Denim Team
