High-purity "SHIRASAGI" activated carbons for pharmaceutical applications
Osaka Gas Chemicals' Shirasagi brand pharmaceutical-grade activated carbon is processed using advanced cleaning technology to meet the purity levels required in pharmaceutical manufacturing, such as for pharmaceutical raw materials, pharmaceutical intermediates, and active pharmaceutical ingredients (synthetic drug substances, proteins, hyaluronic acid, etc.). It also demonstrates high functionality in removing impurities such as residual metals and endotoxins, which are required for active pharmaceutical ingredients.
Osaka Gas Chemicals' activated carbon "Shirasagi" has a long history since it was created by Takeda Pharmaceutical Co., Ltd. in the early 1900s. Since then, we have continued research and development, accumulated expertise and know-how, and reached the top share in the Japanese pharmaceutical industry.
Osaka Gas Chemicals is a leading activated carbon producer. Quality and supply stability is achieved via procurement and selection of raw materials and manufacturing at multiple locations globally.
Adjustments of pore size and particle size for each application
The large scope of SHIRASAGI brand pharmaceutical grade activated carbons covers various pore sizes
adapted to the selective adsorption of each target molecule.
