Abstract
Abstract Scouring cleaning compositions are disclosed in which the abrasive agent consists of agglomerates of finely divided abrasive material an an organic binder for agglomerating such material. Compositions of the invention have good soil-removing properties and improved non-scratching behaviour. They are useful as powdered or liquid household products as well as skin-cleaning products.
