ABSTRACT:
An aqueous light duty liquid detergent composition consisting essentially of, by weight, 10% to 50% of a mixture of a water-soluble alkylbenzene sulfonate detergent salt and a water-soluble alkyl ethenoxy ether sulfate detergent salt in a weight ratio of sulfonate to sulfate in the range of about 0.8:1 to 2:1; about 1% to 8% of an alkanoic acid mono- or di-ethanolamide foam booster; at least about 0.5% to 1.8% of magnesium ions; triethanolammonium ions in an amount to provide a weight ratio of magnesium ion to triethanolammonium ion of 2:1 to 1:2.4; and the balance an aqueous medium, said composition having a pH of 5 to 8 and exhibiting improved oily soil removal and oily solid emulsification properties at a temperature of 18.degree. C. to 26.degree. C. as compared to the same composition without the magnesium and triethanolammonium ions. A method of making said composition comprising the steps of neutralizing alkylbenzene sulfonic acid with magnesium hydroxide to a pH of about 1.5 and thereafter adding sodium hydroxide to increase the pH to the range of 5 to 7, neutralizing the alkyl ethenoxy ether sulfuric acid with a mixture of triethanolamine and ammonium hydroxide, admixing the sulfonate salt with the sulfate salt and thereafter adding said alkanoic acid alkanolamide in liquid form with agitation to form a homogeneous liquid detergent composition. Also described is a method of cleaning articles having oily or greasy soil or a metal or glazed surface comprising contacting said soiled article with water having dissolved therein from 0.5% to 5% by weight of the subject light duty liquid detergent composition.
