Abstract
A solid block detergent composition is described which can be dispensed with a water spray to form an aqueous detergent for cutting and removing grease, removing and suspending soils and rinsing easily leaving cleaned ware. The aqueous detergent concentrate can be used in a cleaning liquid having exceptional soil, particularly grease removing properties with stable foam properties. The solid block detergent contains a package of surfactants including a neutralized anionic surfactant with either one or a mixture of an alkali and alkaline earth metal salt thereof and an alkylpolyglycoside. The active ingredients and polyethylene glycol as a hardening agent are dispersed in a matrix which hardens to form a solid block.
