Abstract
The present invention relates to hard surface cleaning compositions useful in cleaning, and optionally a disinfecting or sanitizing benefit which are particularly adapted to clean lavatory appliances, particularly toilets and the like. The compositions are largely aqueous, thickened, acidic compositions which comprise an acid, a thickening constituent or constituents which form a thickener system, at least one detersive surfactant and at least one superwetter surfactant which is based on a narrow range ethoxylated alcohol nonionic surfactant having two cloud points.
Claims5
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 C8-C32 alkyl chain, R′ is a lower C1-C6 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 C9-C11 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.
