Ecological and Toxicological Association of Dyes

ETAD: The Ecological and Toxicological Association of Dyes and Organic Pigments a continuing effort to improve the industry’s responsible management of synthetic organic colorants shall develop, produce and distribute products in a manner which protects human health and the environment from unacceptable risks during manufacture, transport, use and disposal. shall comply with all applicable laws and regulatory requirements dealing with the safety and the environmental impact of synthetic organic colorants shall inform customers of the safe handling procedures best suited to the products involved.
Our members: Achroma,atul,Clariant,Dystar,color root,Dystar,everlight chemical,Jay-chemical industries,etc.
Our committees:ETAD committees are formed in order to address developments worldwide relating to health and environment issues. The committees combine a supervising role with an active participation to regulatory activities and also promote projects finalized to a better understanding of the ecological and toxicological properties of dye and organic pigments.
Trace metals / impurities:Even high-quality colorants might contain unwanted substances, which need to be identified and whose effect on the product’s properties has to be assessed. Once the substances’ profiles are clarified, appropriate measures will be taken in order to ensure the safe use of colorants. Our current focus is on: Heavy metals: Already in the ‘70s we issued the first recommendation on the content of heavy metals in colorants. These general limits have been incorporated in many regulatory texts and are still the reference, e.g., for textile applications. As latest example, the ZDHC MRSL also refers to these limits for heavy metals in pigments relevant for the apparel industry. More recently we issued recommendations for the metal content of pigments used in toys and food contact applications, and made the requirements for metals in dyes mandatory for all our members. General impurities: The impurity profile of colorants is more and more important for modern standards and regulatory purposes. We constantly update our information on existing and newly identified impurities, update our own references for colorants accordingly, and provide external input to other involved parties.
