Abstract

A detergent composition which is suitable for making into bars for personal washing comprises: (a) 10-60 %wt of a synthetic, non-soap detergent; (b) 10-60 %wt of water-soluble material which is neither soap nor a non-soap detergent and which has a melting point in the range 40 °CC to 100 °C; and (c) 5-50 %wt of water-insoluble material which is neither soap nor a non-soap detergent and which has a melting point in the range 40 °C to 100 °C. The content of water, if any does not exceed 20 %wt of the composition and better is less than 15 %wt. The materials (b) and (c) serve to give structure to the bars. The composition can be propared by melting together the above-mentioned components at a temperature of 50-100 °C, without the conventional energetic working. Desirably the molten mixture contains less than 20 %wt material, other than synthetic, non-soap detergent, which does not enter the liquid phase. The melt can be cast into bars or cooled, milled, plodded and stamped into bars.
