With the recent collaboration between Bluesign and ZDHC, several of the chemistries developed by speciality chemical producer Bolger & O'Hearn are now listed on the official Zero Discharge of Hazardous Chemicals (ZDHC) list of sustainable, approved textile industry chemistries.

The ZDHC Programme aims to drive the global textile, apparel and footwear industries (including leather) towards the use of more sustainable chemistry. Its approach focuses on chemical inputs and the backbone of the Programme is based on the ZDHC Manufacturing Restricted Substances List (ZDHC MRSL); a list of chemical substances banned from intentional use in facilities that process textiles, leather and trim parts in apparel and footwear.

Bluesign is now the first established Level 3 Accepted Certifier for ZDHC MRSL conformance.

Chemistries developed by Bolger & O'Hearn that are now approved by Bluesign and ZDHC include Stormproof/Breathable OmniBloq — an advanced DWR technology engineered to keep apparel dry and consumers comfortable, even when exposed to pounding wind and rain — and Altopel F3, an advanced fluorine-free water repellent.
