- 1 - ABSTRACT OF THE DISCLOSURE A particulate alkaline detergent composition is made from over 15% to 50% of a partially neutralised alkali metal orthophosphate salt, from over 20% to 50% of an alkali metal carbonate salt and from 5% to 40% of a synthetic detergent surfactant. The compositions have good detergency properties in relation to the phosphorus content, especially at low phosphorus levels with over 15% to 30% of orthophos- phate salt, and the use of partially neutralised alkali metal orthophosphate avoids excessively high alkalinity.
