Particulate laundry detergent composition |
(57) A low or zero phosphate laundry detergent composition is based on a particulate partially
neutralized (25-60 mole%) fatty acid mixture, of which up to 35% may be unsaturated.
Preferably, the partially neutralized fatty acid base material is present as spray-cooled
prills. A particulate solid base, for example sodium carbonate or sodium alkaline
silicate, is also present. Non-soap surfactants and other conventional detergent ingredients
may be included. The compositions are free-flowing and have excellent powder properties
as well as good washing performance.
