PROCESS FOR PRODUCTION OF SOLID DETERGENT COMPOSITIONS

摘要

A process for a process for preparing a non-granular solid detergent composition with entrapped gas bubbles, the composition comprising the ingredients:from 5% to 80% by weight of detergent active;from 5% to 30% by weight of water; from 0% to 30% by weight, preferably from 1% to 30% detergency builder; and optionally, one or more other ingredients; which process comprises the steps of:admixture of the ingredients and from 0.1% to 10%, preferably from 1% to 5% by weight of the composition of a chemical blowing agent that decomposes at a temperature in the range from 50 DEG C to 90 DEG C, to generate a gas optionally in presence of water, said chemical blowing agent being incorporated whilst the admixture is at temperature below 50 DEG C;extruding the resultant mix at a temperature of from 50 DEG C to 90 DEG C; and optionally cooling the resultant extrudate, converting it into billets and forming tablets.
