Elementis plc is one of the UK's largest speciality chemicals and personal care businesses, with extensive operations in the United States, Europe and Asia. It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index. Its predecessor business, Harrisons & Crosfield, was formed in 1844 as a tea merchant and traded under that name for 150 years. It became one of the leading British firms in the south-east Asia plantations industry before it gradually divested its interests in the post-colonial era. Diversification initially concentrated on chemicals, timber and builders’ merchants and animal foodstuffs. Eventually, the firm concentrated only on chemicals and changed its name to Elementis.
