Manufacture's Feature

In 1999 we changed our company name from Ichikawa Gohsei Chemical Co. Ltd to Chemicrea Inc., and are now expanding the business field from industrial biocides to fine chemicals including pharmaceutical intermediates and electroics-related products. At the same time we set up a 100% subsidiary company called Chemicrea (Jiangsu) Co. Ltd near Nanjing in 1998 to globalize the production sites. Production of industrial biocides is shifted to our Chinese factory, while building plants for fine chemicals in Japan. In 2003 we established another 100% subsidiary company called Chemicrea (Suzhou) near Shanghai, and it is our strategy to make the best fit of these facilities in China and Japan, i.e., producing earlier stage intermediates in China and doing the later synthetic steps from these intermediates in Japan. Onahama Factory in Japan will concentrate more on (1) new type of biocides and (2) pharmaceutical intermediates with the new GMP plant, which started operation in the year 2001.
