<p>A process for the laundering of textile fabrics, which comprises: (i) a wash step in which the fabrics are immersed in an aqueous wash liquor comprising a detergent surfactant, a detergency builder and optionally other detergent ingredients; (ii) a rinse step in which the fabrics are immersed for at least 30 seconds in an aqueous rinse liquor comprising (a) at least 0.02 g/l of a light coloured crystalline clay mineral, and optionally a non-surfactant water-soluble salt. A composition suitable for use in this process comprises: (a) from 2 to 98 wt% of a light coloured crystalline clay mineral; and (b) from 98 to 2 wt% of a non-surfactant water-soluble inorganic salt, the weight ratio of (a):(b) being from 49:1 to 1:49, and is substantially free of synthetic non-soap surfactant.</p> |
