Liquid detergent composition containing alkylbenzene sulfonate, alkyl ethonal ether sulfate, alkanolamide foam booster and magnesium and triethanolammonium ions

摘要

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-sokluble alkyl ethenoxy ether sulfate detergent salt in a weight ratio 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 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 soil emulsification properties at a temperature of 18 C. to 26 C. as compared to the same composition without the magnesium and triethanolammonium ions. A method of making said composition comprising the steps of neutralizing alylbenzene 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 on 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.
