Patent ID: 7745384

Claim:
A largely aqueous, thickened, acidic composition which exhibits a pH of 4 or less, which comprises: (a) at least one acid; (b) a thickener system which comprises: (b1) a film-forming fatty quaternary ammonium compound according to the following structure: wherein R is a C 8 -C 32 alkyl chain, R′ is a lower C 1 -C 6 alkyl or alkylene group, the sum of both n is between 12-48, and X is a salt-forming counterion which renders the compound water soluble or water dispersible; and (b2) an alkoxylated primary, secondary or tertiary fatty amine compound; (c) at least one superwetter surfactant which is based on a narrow range ethoxylated alcohol nonionic surfactant having two cloud points wherein the narrow range ethoxylated alcohol nonionic surfactant having two cloud points is a C 9 -C 11 nonionic surfactant characterized by one or more of the following: (i) having approximately 5.5 mols ethoxylation, and/or (ii) exhibits an HLB value of about 12-12.4, and/or (iii) when dispersed or dissolved at a 1% concentration in water, said narrow range ethoxylated alcohol nonionic surfactant exhibits one cloud point at 24-29° C. and a second cloud point at 55-58° C.; and (d) at least one additional detersive surfactant.
