It exhibits a high degree of stability upon storage at normal room temperature of the order of about 70 F. over a period of many months without any appreciable precipitation or formation of immiscible layers. It can be subjected to elevated temperatures of the order of 120 F. or cooled to 40 F. and the liquid is in a clear, homogeneous form when returned to room temperature. As a result, the consumer can utilize it conveniently by the addition of small portions to a dishpan or a laundering bath and the detergent and builder salts will be present in constant composition in each portion.
  • the liquid may be employed in any suitable container or packaging material such as metal, plastic, or glass in the form of bottles, bags, cans or drums.

  • the polyethoxamer sulfate material is commonly prepared by reaction of the appropriate alkyl phenol with sufficient ethylene oxide followed by sulfation of the reaction product in known manner, such as by the use of oleum or chlorsulfonic acid. If desired, the poly ethoxamer may be sulfated after the sulfonation of the alkyl aryl hydrocarbon using the same sulfonating agent to produce the mixed detergents.

  • organic impurities comprise unreacted nonionic (unsulfated) higher alkyl phenoxy ethylene oxide materials, ring sulfonated materials such as alkyl phenoxy ethoxamers wherein the phenyl ring is sulfonated, and possibly very small amounts of degradation products such as higher alkyl phenols and partially de-ethoxylated products.
  • organic impurities should be maintained at a minimum since an excessive amount has been found to adversely affect the physical properties and performance of the product. More particularly, an excessive amount, particularly of the unreacted non-ironic polyethoxamer, has a tendency to raise the cloud point, inhibit foam and decrease the efficiency of the product as an emulsifier of greasy soil in washing operations.

  • the reaction product may be purified to remove said organic impurities also, such as by the use of an ion-exchange technique.
  • alkyl aryl sulfonate and sulfated alkyl phenoxy polyethoxamer materials are employed in the form of their alkali metal salts such as the sodium and potassium salts. It is understood that there may be small amounts of inorganic salts such as sodium or potassium sulfate in the sulfonated and sulfated detergents resulting from the method of manufacture. In general, these inorganic sulfate salts should be maintained at as low a iconcentration as practicable.
  • the potassium polyphosphate salts have the property of inhibiting precipitation of calcium and magnesium material in aqueous solution and of contributing to the heavy-duty performance of the liquid detergent product in washing operations. While they may be considered as derived from orthophosphoric acid or the like by the removal of molecularly bound water, any suitable means of manufacture may be employed if desired.
