In 2005, Tata Chemicals, part of the Tata group, acquired the Brunner Mond group. Tata Chemicals is the second-largest producer of soda ash in the world and the only one with manufacturing and supply chain capability in four continents.

The original Brunner Mond and Company was formed in 1873 when John Brunner and Ludwig Mond built Winnington Works at Northwich, Cheshire and produced their first soda ash in 1874. The company grew steadily over the next 50 years including, in 1924, acquiring the Magadi Soda Company of Kenya. In 1926, Brunner Mond merged with three other British chemical companies to form Imperial Chemical Industries (ICI), a venture that grew to become one of the world's largest and most successful companies.

In 1991 Brunner Mond was re-created as an independent company by the acquisition of the UK and Kenyan soda ash businesses from ICI.
