摘要：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 free of surfactant and comprising a detergency builder in a concentration within the range of from 0.1 to 10 g/l. A composition suitable for carrying out this process comprises: (a) from 10 to 99.95 wt.% of a detergency builder, (b) from 0 to 90 wt.% of a pH buffer, the ratio of (a) to (b) being from 99.95:0 to 10:90; and (c) a fluorescer and/or a perfume; the composition being substantially free of organic surfactant.
