Imperial Chemical Industries was a British chemical company. It was, for much of its history, the largest manufacturer in Britain.
It was formed by the merger of four leading British chemical companies in 1926.
Its headquarters were at Millbank in London. ICI was a constituent of the FT 30 and later the FTSE 100 indices.
ICI made general chemicals, plastics, paints, pharmaceuticals and speciality products, including food ingredients, speciality polymers, electronic materials, fragrances and flavourings.
In 2008, it was acquired by AkzoNobel,
which immediately sold parts of ICI to Henkel and integrated ICI's remaining operations within its existing organisation.
