Abstract
A high foaming, nonionic surfactant based, light duty, liquid detergent with desirable cleansing properties and mildness to the human skin comprising: a water soluble nonionic surfactant as the major active ingredient, in an amount in excess of 50% by weight of the total surfactant content; a supplemental amount of a water soluble, foaming, anionic surfactant excluding the ethoxylated alkyl ether sulfates; and a lesser amount of a water soluble, foaming zwitterionic betaine surfactant, a C.sub.12-14 alkyl monoalkanol amide, a C.sub.12-14 alkyl dialkanol amide, and a amine oxide.
Claims9
A high foaming, nonionic surfactant based, light duty, liquid detergent comprising approximately, by weight,
- (a) 10% to 30% of a water soluble nonionic surfactant selected from the group consisting of primary and secondary C.sub.8 -C.sub.18 alkanol condensates with about 5 to 30 moles of ethylene oxide, condensates of C.sub.8 -C.sub.18 alkylphenol with about 5 to 30 moles of ethylene oxide, condensates of C.sub.8 -C.sub.20 alkanol with a heteric mixture of ethylene oxide and propylene oxide having a weight ratio of ethylene oxide to propylene oxide from 2.5:1 to 4:1 and a total alkylene oxide content of 60% to 85% by weight and condensates of 2 to 30 moles of ethylene oxide with sorbitan mono and tri- C.sub.10 -C.sub.20 alkanoic acid esters having an HLB of 8 to 15;
- (b) 1% to 10% of a water-soluble anionic detergent selected from the group consisting of C.sub.8 -C.sub.18 alkyl sulfates, C.sub.8 -C.sub.16 alkylbenzene sulfonates, C.sub.10 -C.sub.20 paraffin sulfonates, C.sub.10 -C.sub.24 alpha olefin sulfonates, C.sub.8 -C.sub.18 alkyl sulfosuccinate esters, C.sub.8 -C.sub.18 acyl isethionates and C.sub.8 -C.sub.18 acyl taurates;
- and
- (c) 0.5% to 10% of a water-soluble betaine;
- (d) 1 to 3 wt. % of a C.sub.12-14 alkyl monoalkanol amide;
- (e) 1 to 3 wt. % of a C.sub.12-14 alkyl dialkanol amide;
- (f) 1% to 5% of a water soluble amine oxide;
- and
- (g) the balance being water as an aqueous medium in which said nonionic surfactant, said anionic detergent, said betaine, said C.sub.12-14 alkyl monoalkanol amide, said C.sub.12-14 alkyl dialkanol amide and said amine oxide are solubilized in said water, wherein the sum of B, C, D, E and F being from 15% to 48% by weight of the composition of the total surfactant content, said nonionic surfactant being in excess of 50% by weight of the total surfactant content, said composition does not contain any ethoxylated alkyl ether sulfate and said composition does not contain any polyoxyalkylene glycol fatty ester.
