Liquid dishwashing detergent containing anionic surfactant, suds stabilizer and highly ethoxylated nonionic drainage promotor

Claim 1

A liquid detergent composition comprising, by weight: (a) from about 10% to about 50% of an anionic surfactant; (b) from about 3% to about 8% of a drainage promoting nonionic surfactant selected from the group consisting of: (i) an ethoxylated aliphatic alcohol of the formula R(OC.sub.2 H.sub.4).sub.n OH wherein R is an aliphatic hydrocarbyl radical containing from about 16 to about 30 carbon atoms, and n is from about 16 to about 100; (ii) an ethoxylated alkyl phenol of the formula R(OC.sub.2 H.sub.4).sub.n OH wherein R is an alkyl phenyl radical containing a total of from about 18 to about 30 carbon atoms and at least one alkyl group containing at least about 12 carbon atoms, and n is from about 16 to about 100; (iii) the condensation product of mono C 16-22 fatty acid esters of polyglycols with from about 13 to about 100 moles of ethylene oxide per mole of the monoester; (iv) the condensation product of cholesterol and from about 13 to about 100 moles of ethylene oxide; (v) a material which is a condensate of ethylene oxide, propylene oxide and a compound containing hydroxy or amine groups onto which alkylene oxides can be polymerized, said polymer having a molecular weight of from about 500 to about 15,000, an ethylene oxide content of from about 30% to about 70% by weight and a propylene oxide content of from about 30% to about 70% by weight; and (vi) mixtures thereof; (c) from about 2% to about 8% of a suds stabilizing nonionic surfactant selected from the group consisting of amine oxides, ammonia, monoethanol and diethanol amides of fatty acids having an acyl moiety of from about 8 to about 18 carbon atoms, and mixtures thereof; (d) from 0% to about 10% of a detergency builder selected from inorganic phosphates, polyphosphates, silicates and carbonates, organic carboxylates, phosphonates and mixtures thereof; and (e) from about 20% to about 88% water.
