Abstract
There is provided a particulate solid machine dishwashing detergent composition containing alkali metal percarbonate bleach coated with a mixed salt comprising an alkali metal carbonate and an alkali metal sulphate salt; a peroxyacid bleach precursor; an acidification agent; and a means for enabling delayed release of said acidification agent such that the pH of said composition as a 1% solution in water at 20<o>C is from 9.5 to 13.0 prior to release of said acidification agent, and such that the pH of said composition as a 1% solution in water at 20<o>C is from 9.3 to 7.0 subsequent to complete release of said acidification agent.
