Its principal products are soda ash, sodium bicarbonate, calcium chloride and associated alkaline chemicals.

[4] During the early twentieth century the company built managers' and workers' houses in Hartford, Cheshire.

In 1998, this company acquired the soda ash production capabilities of Akzo Nobel in The Netherlands to form Brunner Mond B.V.[6] In April 2010 operations director Dr Martin Ashcroft replaced John Kerrigan as managing director.

This vertical acquisition gave longer term raw commodity price certainty and an economy of transport distance for one of the company's largest factories.
