Patent ID: 6897187

Claim:
A light duty liquid cleaner consisting of a) water; b) from 1 to 40% by weight of an anionic surfactant; c) from 0.01 to 10% by weight of a cationic compound of the formula wherein R 1 is selected from the group consisting of C 8 -C 22 -alkyl, C 8 -C 22 -alkenyl, C 8 -C 22 -alkyl/alkenylamidopropyl, C 8 -C 22 alkoxyalkenylethyl, C 8 -C 22 -alkyl/alkenyi(poly)alkoxyalkyl, C 8 -C 22 -alkanoylethyl, C 8 -C 22 -alkenoylethyl, and mixtures thereof, R 2 is a group of the formula —A—(OA) n —OH, R 3 and R 4 are selected from the group consisting of C 1 -C 22 -alkyl, C 2 -C 21 -alkenyl, or mixtures thereof. A is —C 2 H 4 — and/or —C 3 H 6 — and n is a number from 0 to 20 and X is an anion; d) from 0.05 to 15% by weight of a non-ionic surfactant and/or an amphoteric surfactant; e) at least one additive or auxiliary selected from the group consisting of builders, salts, solubilizers, solvents, enzymes, thickeners, preservatives, fragrances, dyes, pearlizing agents, emulsifiers, sequestering agents, and mixtures thereof, wherein said thickeners are selected from the group consisting of hydrogenated castor oil, salts of long-chain fatty acids, polysaccharides, carboxymethylcellulose, hydrocellulose, polyethylene glycol mono- and di esters of fatty acids, poly acrylates, polyvinyl alcohol, polyvinylpyrolidone, electrolytes, and mixtures thereof; and wherein in said light duty cleaner glycols are dispensed with.
