Abstract

Abstract Soap compositions are provided capable of dispersing lime soaps formed by soap in hard water, and comprising a watersoluble fatty acid soap, an amount within the range from about 5 to about 15 percent by weight of free fatty acid having from about ten to about twenty-two carbon atoms, and an amount within the range from about 0.5 to about 3 percent by weight of an alkyl or alkyl phenol ether of an oxyalkylene glycol sulfate.
