Abstract
In a process for making detergent tablets comprising spraying a coating of a water-soluble organic polymeric binder onto the exterior of particles of detergent composition containing detergent active and detergency builder and compacting the composition, the improvement comprises spraying an external coating of a film-forming water-soluble organic polymer onto the tablets. The coating on the tablet exterior reduces friability and abrasion and provides extra enhancement of strength while permitting disintegration/dissolution in a wash liquor.
