PROCESS FOR DETERGENT BAR MANUFACTURE

摘要

The invention provides a process for the preparation of detergent bars not containing clay, comprising the steps ofa) reacting the precursor of a detergent active with an alkaline material;b) adding a mixture of at least one polyol and a boron containing compound;c) adding sodium alumino silicate or generating in situ sodium alumino-silicate by allowing a source of monomeric aluminium to condense with silicate anion;d) adding if desired other detergent actives, builders and minor ingredients; andconverting the product into bars by conventional method. The resulting bar includes 5-70% by weight of detergent active, 0.5 to 30% by weight of boron- polyol gel, 1-15% by weight of aluminosilicate, and water.
