sulphates
Minerals containing sulfur
Sulphates are chemical compounds containing the sulphate ion—a sulfur atom bonded to four oxygen atoms.
They appear in fertilizers, detergents, and industrial processes.
In everyday contexts, sulphates usually refer to ingredients in shampoos and cleansers: sulfate-free shampoo.
The spelling sulphate is British; American English uses sulfate.
