## Abstract

A high foaming, light duty, liquid detergent with desirable cleansing properties and mildness to the human skin comprising a disinfecting agent, four essential surfactants: a water soluble nonionic surfactant, a C.sub.8-18 ethoxylated alkyl ether sulfate anionic surfactant, two sulfonate surfactants, and the balance being water.

## Claims

### Claim 1

A high foaming light duty, liquid detergent comprising approximately by weight:
(a) 5% to 15% of a water soluble nonionic surfactant selected from the group consisting of primary and secondary C.sub.8-18 alkanol condensates with 5 to 30 moles of ethylene oxide, condensates of C.sub.8-18 alkylphenol with 5 to 30 moles of ethylene oxide, condensates of C.sub.8-20 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.10-20 alkanoic add esters having an HLB of 8 to 15;
(b) 5% to 15% of a water-soluble anionic detergent which is an ammonium or alkali metal salt of a C.sub.8-18 ethoxylated alkyl ether sulfate;
(c) 0.5% to 10% of an alkyl metal salt of a linear alkyl benzene sulfonate sulfonate;
(d) 0.5% to 10% of an alkaline earth metal salt of a linear alkyl benzene sulfonate;
(e) 0.5% to 1.5% of an iodine powder which is complexed with said nonionic surfactant; and
(f) the balance being water.

### Claim 2 (depends on 1)

A liquid detergent composition according to claim 1, wherein said nonionic surfactant is said condensate of a primary C.sub.8 -C.sub.18 alkanol with 5 to 30 moles of ethylene oxide.

### Claim 3 (depends on 1)

A liquid detergent composition according to claim 1 further including a preservative.

### Claim 4 (depends on 1)

A liquid detergent composition, according to claim 1, further including a color stabilizer.

### Claim 5 (depends on 1)

A liquid detergent composition according to claim 1, further including about 1.0 to about 15 wt. % of a cosolubilizing agent selected from the group consisting of C.sub.2-3 mono- and di-hydroxy alkanols, water soluble salts of C.sub.1-3 substituted benzene sulfonate hydrotropes and mixtures thereof.
