First European Order for Latest Plant-Based Detergent Ingredient

Itaconix (AIM: ITX) (OTCQB: ITXXF), a leading innovator in plant-based specialty polymers, is pleased to announce the first shipment to an EU-based customer for its Itaconix® TSI™ 322 sustainable detergent polymer.

The new customer is an established and well-respected European brand that is recognized by both the detergent industry and consumers as a leader in product innovation, performance, and sustainability. The Itaconix polymer is a key ingredient in a new non-phosphate dishwashing detergent which the customer is expected to have on European retail shelves by early 2022. Itaconix® TSI™ 322 allows detergent formulators to meet increasing consumer and retailer demands for sustainable products without compromising on cost or performance.

John R. Shaw, CEO of Itaconix, said:

“Our Itaconix® TSI™ 322 polymer continues to gain momentum as a key ingredient in North American dishwashing detergent formulations. Replicating this success in Europe is an important milestone we set for 2021, particularly as we experienced delays in European formulation activity due to the Covid-19 pandemic. We are delighted that an innovation leader in European dishwashing detergents is adopting Itaconix® TSI™ 322 to meet the brand’s performance, price, and sustainability goals. This order further validates the opportunity for Itaconix® TSI™ 322 to set new standards for consumer value in an emerging generation of safer detergent products.”
