No financial details were given, while the end customer was simply described as a “major producer of non-phosphate automatic dishwashing detergent products”.
The deal is a significant milestone for the business, which has seen traction for its environmentally-friendly product in North America.
"As phosphates are phased out due to environmental concerns, our novel bio-based polymers are stepping in to enable a new generation of safer detergent products that set new standards for performance, value, and increased sustainability,” said Itaconix chief executive John Shaw.
“We expect European detergent use will support our forecast revenues for 2020 and beyond."
The company designs and manufactures high-performance, cost effective and sustainable ingredients that are key components of products in the personal care, homecare and industrial sectors. It does so by developing and producing bio-based polymers from itaconic acid – hence the name.
