ETAD Releases Updated Guide on Dye Impurities

October 21, 2014

The Ecological and Toxicological Association of Dyes and Organic Pigments Manufacturers (ETAD) have published an updated guide to threshold limits on organic impurities in dyes.

The updated guide addresses the question of the presence of impurities in dyes and their potential impact on the environment. In addition, the guide addresses the many different standards any of which typically includes both a specific impurity profile for the dyes and limits for trace impurities in the final textile products that have to be considered in order to provide suitable products for the dying process.

The revision aligns the document with the Zero Discharge of Hazardous Chemicals'(ZDHC) list of manufacturing restricted substances (MRSL) for the apparel and footwear industry, which brings together international brands and retailers seeking to minimize the environmental impact of their products.
