Abstract
A high foaming, nonionic surfactant based, light duty, liquid detergent with desirable cleansing properties and mildness to the human skin comprising four essential surfactants: 1. a water soluble nonionic surfactant as the major active ingredient, in an amount in excess of 50% by weight of the total surfactant content; 2. a supplemental amount of a water soluble, foaming, anionic surfactant excluding the ethoxylated alkyl ether sulfates; 3. a lesser amount of a water soluble, foaming zwitterionic betaine surfactant; and 4. a minor amount of a fatty acid alkanolamide foam stabilizer; dissolved in an aqueous vehicle.
Claims9
A high foaming, nonionic surfactant-based, light duty, liquid detergent consisting essentially of, by weight, (A) 13% to 25% of a water soluble nonionic surfactant selected from the group consisting of primary and secondary C.sub.8 -C.sub.18 alkanol condensates with 5 to 30 moles of ethylene oxide, condensates of C.sub.8 -C.sub.18 alkylphenol with 5to 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) 2% to 8% 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 and 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;
- (C) 2% to 6% of a water-soluble C.sub.8 -C.sub.18 alkyl amidopropyl dimethyl betaine;
- (D) 2% to 6% of a C.sub.12 -C.sub.14 fatty acid monoethanolamide foam stabilizer;
- solubilized in (E) an aqueous medium;
- the sum of A-D being from 20% to 40% by weight of the composition, said nonionic surfactant being in excess of 50% by weight of said sum and said composition being free of anionic alkyl ether polyethenoxy sulfate detergent.
