摘要 |
A detergent composition which is suitable for making into bars for personal washing comprises:(a) 10 to 60% wt. of a synthetic, non-soap detergent;(b) 20 to 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° C. to 100° C.; and(c) 5 to 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 compositions can be prepared 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, optionally milled and plodded and stamped into bars.
