Cinven and Bain Capital-backed Arxada, a specialty chemicals firm, completed the acquisition of Enviro Tech Chemical Services, a manufacturer of proprietary and high-efficacy antimicrobial and biocidal products. Financial terms were not disclosed. "The acquisition of Enviro Tech is another important and strategic deal for Arxada as we extend our position within the microbial control industry. Enviro Tech brings direct access to the $6bn food and beverage hygiene market and adds capabilities in sustainable and highly complementary chemistries. This is our second strategic transaction in our first six months as an independent company, and further reinforces our commitment to adding new products and end-markets to our growing Microbial Control Solutions portfolio," Marc Doyle, Arxada CEO.
