| 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. n The strength of such tablets is improved, without detriment to other properties, by tabletting at a temperature above ambient but below the melting point of the polymeric binder. n Preferably the temperature is only 5°C to 10°C below the melting point of the binder. |
