Itaconix (AIM: ITX) (OTCQB: ITXXF), a leading innovator in plant-based specialty polymers used as essential ingredients in everyday consumer products, is pleased to announce a new global agreement with Croda Inc. ("Croda") in odour control, which serves to extend a supply collaboration that began in 2017.

Under the terms of the new supply agreement, Itaconix will continue to produce and supply the proprietary ZINADOR® odor neutralizing ingredients for Croda to market and sell globally in home care applications.  The new agreement adds a newly formulated product to the collaboration and updates the terms and arrangements for ongoing market developments.

Scott Tuchinsky, North America Business Head Consumer Care at Croda, commented:

"The ZINADOR® products are an important part of our plans to continue growing our leadership position in sensory technologies and solutions. We have established a global customer base for these products through our initial efforts and see attractive opportunities for further success as more brands and consumers choose the performance and sustainability benefits of Itaconix polymer technologies."

John R. Shaw, CEO of Itaconix, added:

"Our collaboration with Croda is bringing the value of our odour neutralisation to more customers around the world in a growing range of fabric and air care products. We are pleased with Croda's continued commitment to working with Itaconix, and are excited that this new agreement expands our partnership. I expect continued progress in brand usage and new applications through our joint efforts."
