ABSTRACT:
A detergent laundry bar, based on sodium higher fatty alcohol sulfate, which is resistant to breakage on handling, includes sodium higher fatty alcohol sulfate in which the higher fatty alcohol is of about 10 to 18 carbon atoms, water soluble builder salt for the sodium higher fatty alcohol sulfate, water insoluble particulate material which may also possess building properties, water and a higher fatty acid of 10 to 18 carbon atoms, with the proportion of higher fatty acid being such as to aid in overcoming the tendency of such laundry bars to crack, chip and break on handling. The water soluble builder salt will normally include an inorganic phosphate builder salt, such as sodium tripolyphosphate, and the water insoluble particulate material will normally include calcium carbonate and/or bentonite, and/or talc, usually being constituted of two or three of such materials. Preferably a higher fatty acid alkanolamide and a higher fatty alcohol will also be present.
Also described is a process for manufacturing such detergent laundry bars, which process includes milling and plodding operations.
