Our Corporate Motto

"Chemicals for the Benefit of the Earth and Mankind”

The 21st century has brought a paradigm shift in values shared by people around the world. The age of total faith in science and technology as the path to greater convenience and prosperity for mankind is over. A new set of values has defined a new role for science and technology in what will be an ongoing challenge for mankind to coexist with the environment that nurtures us. In other words, we must now focus our human ingenuity on a new generation of environmentally friendly science and technology.
