Global leader in specialty chemicals towards sustainable solutions, Archromaand Stony Creek Colors, a trusted manufacturer of traceable natural indigo dyes, have entered into a strategic partnership to produce Stony Creek’s IndiGold™ high-performance plant-based pre-reduced indigo at scale.

Stony Creek Colors developed the new IndiGold™ concept as the world’s first pre-reduced natural indigo dye, which was then developed with Archroma to offer the first ever plant-based alternative to synthetic pre-reduced indigo. The dyestuff will be sold as a 20 per cent concentration in a soluble liquid form that displays similar performance to comparable synthetic indigo products available on the market.

Stony Creek Colors evolved into an innovative leader in plant-based indigo due to its complete development of an improved agricultural value chain, from seed breeding and production to biomass harvest and extraction. The company has been selling its US grown indigo to denim mills since 2015.

The pre-reduced plant-based indigo partnership took root in 2020 when Stony Creek was looking to work with like-minded partners to produce the new dyestuff at scale. Archroma emerged as the ideal partner as the company is well known for its expertise in indigo manufacturing and application, as well as for its commitment to transform the denim industry towards creating better blue jeans.
