ST GALLEN – Starting next month, Bluesign will publish threshold limits for chemical substances in finished products such as textile auxiliaries or dyes that are listed as having carcinogenic, mutagenic, or reprotoxic properties.
The new Bluesign System Black Limits (BSBL) will also cover substances that fall under POP (persistent organic pollutant) regulation and lists monomers used in textile dyes and chemicals such as acrylamide, acrylonitrile or ethylene oxide.
“The idea behind the BSBL is different from the MRSL approach,” said the company. “Unlike MRSL, the BSBL is not intended to be sent out to the supply chain for the purpose of obtaining a less substantial and conclusive compliance declaration from the supply chain maze. Rather, its main purpose is to manage hazardous substances in finished chemical products.
“When limits are publicly available, transparency increases.”
