<p>A PROCESS IS PROVIDED FOR PREPARING A NON-GRANULAR SOLID DETERGENT COMPOSITION WITH ENTRAPPED GAS BUBBLES, THE COMPOSITION COMPRISING: 5-80% BY WEIGHT OF DETERGENT ACTIVE; 0.1-10% BY WEIGHT OF A CHEMICAL BLOWING AGENT THAT DECOMPOSES TO GENERATE A GAS AT A TEMPERATURE RANGE 50-90°C OPTIONALLY IN PRESENCE OF WATER; 5-30% BY WEIGHT OF WATER; AND 0-30% BY WEIGHT OF DETERGENCY BUILDER; WHICH PROCESS COMPRISES THE STEPS OF I. MIXING THE VARIOUS INGREDIENTS OF THE FORMULATION IN A MIXER; II. MIXING 0.1-10% OF THE CHEMICAL BLOWING AGENT TO THE SAID MIX AT A TEMPERATURE BELOW 50° C; III. EXTRUDING THE SAID MIX AT A TEMPERATURE OF 50-90°C WHEREIN HEAT IS PROVIDED TO THE SAID MIX FROM THE OUTSIDE BY HEATING THE EXTRUDER BARREL AND FROM THE INSIDE BY HEATING THE SCREW SHAFT AND/OR THE SCREW FLIGHTS; AND, IV. OPTIONALLY, COOLING THE EXTRUDED BARS, CONVERTING THEM INTO BILLETS AND FORMING TABLETS.</p> |
