Latest bluesign® update emphases on aniline limitations

As part of the yearly update to its chemical ingredient listings, bluesign® has strengthened its standards for free aniline content in textile chemicals, such as indigo dyes, in response to changes in US EPA rules.

All bluesign® ‘Approved’ indigo kinds now need aniline reduced indigo. It’s likewise prohibited in other dyes and auxiliaries, with a 500 mg/kg restriction (ppm) Limits on solvents used in printing inks and a variety of other auxiliary chemicals have also been tightened by bluesign®.

Regulatory bodies such as the United States Environmental Protection Agency impacted the decision to restrict the use of free aniline in formulations.

bluesign® has established a new consumer safety limit for 2-pyrrolidone, a solvent often used in printing inks. The mid-term aim is to specify a prohibition on the use of N-methylolacrylamide, which must be designated as hazardous to reproduction. bluesign® also specifies a restriction on the use of 2 Butanone oxime, which is carcinogenic and is already listed on BSSL – consumer safety limits.

The Swiss-based chemical management specialist has also tightened up limits on solvents used in printing inks and a range of other auxiliary chemicals.
