Archroma, a global leader in specialty chemicals towards sustainable solutions, and Stony Creek Colors (“Stony Creek”), a trusted manufacturer of traceable natural indigo dyes, today announced that they had entered a strategic partnership to produce and bring to the market Stony Creek’s IndiGold™ high-performance plant-based pre-reduced indigo at scale.
Stony Creek extracts its dye from proprietary Indigofera plant varieties grown in partnership with family farms as a regenerative rotational crop. Stony Creek Colors developed the new IndiGold™ concept as the world’s first pre-reduced natural indigo dye, then developed with Archroma to offer the first-ever plant-based alternative to synthetic pre-reduced indigo. The dyestuff will be sold at a 20% 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. Archroma continuously introduces eco-advanced indigo innovations such as the first-ever aniline-free synthetic pre-reduced indigo or the Archroma x CleanKore technology for aniline-free potassium permanganate-free* spray and laser booster for white abrasion.
Archroma immediately offered to support the idea of Stony Creek Colors with extensive pilot-scale manufacturing trials and engaged with its network of denim machinery manufacturers to test the first samples in industrial conditions.
