Our Locations

Headquarters Hamburg
The company’s entire sales activities and the central business areas of finance, controlling, human resources and IT are concentrated at its headquarters in the city of Hamburg.
Our CARE Studio, the development laboratory that was opened in 2018 for Personal Care, is also located in Hamburg. Here our experts concentrate both on the development of innovative raw materials and on new applications in the field of cosmetics. Our aim is to support our customers in increasing the popularity of their care products with consumers through the ideally tailored use of vegetable-based products from IOI. In addition to the creation of new raw materials, new textures and the optimisation of sensory characteristics of end products, the CARE Studio’s range of services also includes training for those interested in learning more about the possibilities and methods of modern formulation relating to Personal Care.
Altogether, 40 employees are based in Hamburg.

Production Site Witten
The industrial site in Witten in the southwest of the Ruhr district was originally founded in 1905 as a soap factory under the name of “Märkische Seifen-Industrie Witten”, which initially produced detergents and cleansing agents in its steadily growing production plants. Later on, the focus of production was extended to include oleochemistry in order to also produce the raw materials needed for making soap. A significant oleochemical production site for the most diverse materials based on natural fats and oils developed from these beginnings over the following decades.
Our production facilities all represent the state of the art and are operated with monitoring and process control technology. We have already been meeting the high GMP (Good Manufacturing Practice) standards of the pharmaceutical industry since 2005 with our production processes. This also includes regular audits by the district government of Arnsberg (most recently in May 2021) to confirm the GMP certificate and by the U.S. Food and Drug Administration – FDA – (most recently in January 2020).
Today IOI Oleo GmbH employs over 150 people at this site.
