ABSTRACT:
Detergent tablets, compacted from detergent powder containing detergent active and detergency builder, contain a polymer which acts as binder and as a disintegrant when the tablets are added to water. Preferably the binder is sprayed into the powder before compaction. The strength of such tablets is improved, without detriment to other properties, by tabletting at a temperature above ambient but below melting point of the polymeric binder. Preferably the temperature is only 5.degree. C. to 10.degree. C. below the melting point of the binder.
