Archroma, a global leader in specialty chemicals towards sustainable solutions, and Stony Creek Colors (“Stony Creek”), a trusted manufacturer of traceable natural indigo dyes, announced that they have 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, 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 percent concentration in a soluble liquid form that displays similar performance to comparable synthetic indigo products available on the market.
