Since its foundation, ETAD has accompanied its activity of monitoring ecological and toxicological issues on colorants with the development of corresponding methods for the determination of substances and properties of concern.
Thanks to the expertise of ETAD’s member companies, it has been possible to develop methods which suit the specific chemicophysical properties of dyes and organic pigments and allow a correct assessment of their impact on health and the environment.
The complete list of ETAD Methods can be read below or downloaded as a pdf file.
