Abstract:
A detergent bar composition comprising:(a) 10 to 60% wt. of a synthetic, non-soap detergent;(b) 20 to 60% wt. of water soluble material which has a melting point in the range 40.degree. C. to 100.degree. C. and which is selected from the group consisting of:(i) polyalkylene oxide;(ii) a mixture of polyalkylene oxides; and(iii) block copolymers of polyethylene oxide and polypropylene oxide;(c) 5 to 50% wt. of water-insoluble material which has a melting point in the range 40.degree. C. to 100.degree. C. and which is fatty acid having carbon chain length of 12 to 24 carbons;(d) 1 to 14% by wt. water; and(e) 0 to 20% wt. of material which is other than synthetic non-soap detergent and which does not melt below 100.degree. C.;wherein said compositions are prepared by:(1) mixing synthetic non-soap detergent (a) and materials (b) and (c) at 50.degree. to 90.degree. C.;(2) cooling product of step (1) until said product solidifies; and(3) forming said product of step (1) into a bar; said step (3) comprising a milling step.
