Abstract

of the Invention An aqueous liquid detergent composition especially adapted for dishwashing, comprising 5-60% by weight of an organic synthetic surfactant system of at least two surfactants, and 5-50% by weight of a citrus juice, said organic synthetic surfactant system consisting of1) from about 30-90 parts by weight of the surfactant system of a Ca-sensitive first surfactant selected from the group consisting Water-soluble C8-16 alkyl benzene sulphonates; alkane sulphonates having 8-20 car-bon atoms; olefin sulphonates having from 8-20 carbon atoms; di-C8-20-alkyl sulpho-succinates; di-C6-12-alkyl phenol sulphosuccinates; primary and secondary alkyl suphates having 8-20 carbon atoms; C8-20 alkyl polyethoxy sulphates having 1-25 ethoxy groups and mixtures thereof, and2) from about 70-10 parts by weight of said system of a less Ca-sensitive second surfactant selected from the group consisting of water-soluble nonionic condensation products obtained by condensing from 5-30 moles of an alkylene oxide, preferably ethylene or propylene oxide with one mole of an organic hydrophobic compound, aliphatic or alkyl aromatic in nature, having 8 to 24 carbon atoms and at least one reactive hydrogen atom, particularly a reactive hydroxyl, amino, amido or carboxyl group; C8-20-alkylsulphobetaines; amines oxides containing one long chain alkyl moiety of from 10-28 carbon atoms and two moieties which can be either alkyl radicals or hydroxyalkyl radicals having from 1-4 carbon atoms; C8-20 alkyl-polyethoxy sulphates having from 1-25 ethoxy groups, and mixtures thereof, said surfactants of group (1) and the ion-active surfactants of group (2) being present in the form of their alkalimetal salts, ammonium salts, or mixtures thereof. The composition is an effective liquid dishwashing composition with improved cleaning performance on difficult soils.
