Ecolab Inc., a provider of water, hygiene and energy services, has sold its phosphonate component business in China to specialty chemicals group Italmatch Chemicals S.p.A..
Ecolab acquired the business in 2015 as part of its deal for a controlling interest in China-based Jianghai Environmental Protection Co. Ltd.
