1. A liquid cleaning and disinfecting composition comprising:
- a) from about 5% to about 20% linear alkyl dimethyl amine oxide;
b) a divalent metal salt selected from the group consisting of Zn carbonate, Zn sulphate, Zn citrate and mixtures thereof;
c) from about 4 to about 40% of an anionic surfactant selected from the group consisting of alkyl sulfate, alkyl ethoxy sulfates and mixtures thereof;
d) from about 0.1 to about 20% of a nonionic surfactant selected from the group consisting of C8-C22 aliphatic alcohols with 1 to 25 moles of ethylene oxide, alkylpolyglycosides, fatty acid amide surfactants, and mixtures thereof; and
e) at least one biocide selected from the group consisting of a halogenated benzyl alcohol derivative, a halogenated hydroxydiphenylether, a quaternary ammonium salt, an alkylbenzethonium chloride, a peroxide bleach system, and mixtures thereof.

Abstract
The present invention relates to cleaning and disinfecting liquid detergent compositions and, in one embodiment, liquid hand dishwashing compositions, comprising a metal salt, preferably a divalent metal salt, preferably Zn2+-salt and linear alkyl nucleophilic surfactant, preferably a linear alkyl chain amine oxide.
The present invention further relates to methods of disinfecting dishware and/or dishwashing implements and/or skin using such a liquid detergent compositions.
