Definitions

  • ABSTRACT Soap compositions 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 to about 15 percent by weight of free fatty acid having from about ten to about twenty-two carbon atoms, and anamount 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.
  • British Pat. No. 945,062 describes toilet soap compositions containing more than 5 percent alkyl ether sul fates.
  • synthetic surfactants such as nonionic surfactants or alkyl ether sulfates
  • the surfactant considerably reduces plasticity, resulting in an increased tendency towards crack formation, and the composition also has an increased tendency to swell when in contact with moisture.
  • soap powders In soap powders, an admixture of as muchas 5 percent of a surfactant or dispersing agent in the form of a nonionic surfactant, such as a polyoxyalkylene glycol ether, results in the powders becoming soft and sticky, so that they are difficult to process during manufacture, and also tend to become lumpy and form large agglomerates in storage. Therefore, in soap powders a small amount of nonionic surfactantis generally used, together with a sodium tripolyphosphate or other sodium polyphosphate salt for lime soap dispersion.
  • a nonionic surfactantis generally used, together with a sodium tripolyphosphate or other sodium polyphosphate salt for lime soap dispersion.
  • an addition of from 4 to 5 percent of an anionic surfactant as the dispersing agent generally causes no change in the physical characteristics of the soap powder, but results in an undesirable stabilization of the lather volume in the washing solution, which is particularly disadvantageous when the composition is used for washing in automatic washing machines.
  • an anionic surfactant for example, an alkyl ether sulfate
  • soap compositions are provided based on a water-soluble fatty acid soap, comprising an amount within the range from about 5 to about 15 percent by weight of the soap 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 the soap of an alkyl or alkyl phenol oxyalkylene ether sulfate in which the alkyl group has from about ten to about twenty carbon atoms and the alkyl phenol has an alkyl chain having from about eight to about fifteen carbon atoms and the oxyalkylene unit is derived from ethylene oxide, propylene oxide, butylene oxide or mixtures thereof.
  • compositions give a substantially complete dispersion of lime soaps at temperatures as low as 40C. and a soap concentration of as low as 1 gram per liter of water having a hardness of 20 These compositions also have substantially the same physical properties as ordinary soap with respect to plasticity and swellability in the presence of moisture.
