The company was established on 2 March 1988 in Copenhagen. Esti Kemi A/S was an independent company until October 1991, when Haltermann AG, with head office in Hamburg/Germany, acquired the complete share capital. The company name was changed to Esti Chem A/S as most of the activities were devoted to the export markets. The Haltermann Group was founded on 8. January 1898 in Hamburg by Johann Haltermann with hydrocarbon solvents, mineral oils, and special blends as the main products.

Esti Chem´s products were sold as environmentally friendly alternatives to hydrocarbons, and the sales was expanding in many market segments, where the environmental pressure on traditional solvents was increasing.

Esti Chem was working as a specialties chemicals company within DOW until April 2006, where Esti Chem was acquired by Additiv-Chemie Luers GmbH & Co. (ACL).
