ST GALLEN – In response to changes in the US EPA guidelines, Bluesign has tightened up its requirements for free aniline content in textile chemicals – such as indigo dyes – as part of the annual update to its chemical substance lists.
Restriction for free aniline content in chemicals has become more stringent with aniline reduced indigo now a must for all Bluesign ‘Approved’ indigo types, while it’s also restricted in other dyes and auxiliaries with a limit of 500 mg/kg (ppm).
The Swiss-based chemical management specialist has also tightened up limits on solvents used in printing inks and a range of other auxiliary chemicals.
The revision covers all the updates to the restrictions for chemical substances published in the Bluesign System Substances List (BSSL) and the Bluesign System Black Limits (BSBL).
