Abstract
A low temperature process for washing laundry in a domestic washing machine is provided. In this process a detergent composition of bulk density > 650 g/litre is delivered to the wash via a dispensing device. The detergent composition comprises a bleach activator and a coated alkali metal percarbonate bleach wherein the coating material is a mixed salt of an alkali metal carbonate and alkali metal sulphate. The washing process is conducted at a temperature of no more than 50 C.
