Acidic, thickened cleaning and disinfecting compositions which exhibit good long term shelf stability, are particularly effective in the removal of limescale from hard surfaces, and which are effective against gram positive and gram negative bacteria. The compositions comprise one or more nonionic surfactants; one or more quaternary ammonium surfactant compounds having germicidal properties; an acid mixture comprising formic acid and one or more water soluble organic acids, particularly water soluble organic acids selected from the group consisting of: lactic acid, citric acid, glycolic acid and where the formic acid and one or more water soluble organic acids are present in a weight ratio of formic acid: formic acid:water soluble organic acid(s) of 1:0.1-10; a cellulose based thickening composition; optionally but desirably a one or more conventional additives such as a coloring agent, fragrance or pH adjusting agent; and, water. The compositions may also include further conventional adjuvants such as perfumes and coloring agents in minor amounts. The compositions feature surprisingly good viscosity retention over time notwithstanding the presence of formic acid and cellulose based thickeners in the compositions.

Thickened acidic, hard surface cleaning and disinfecting compositions particularly useful for ceramic surfaces

A pigmented bleach-containing hard surface cleaner comprises an alkali metal hypochlorite, bentonite clay, a mono-(long chain alkyl)-tertiary amine oxide, an alkali metal salt, a pH stabilizer to attain a pH of 11 or higher, an alkali metal alkyl sarcosinate, an alkylbenzene sulphonate, and an inorganic pigment which is preferably ultramarine blue. The cleaning composition has excellent colour stability as well as phase stability and hypochlorite stability.

Pigmented rheopectic cleaning compositions with thixotropic properties

Aqueous acidic thixotropic hard surface cleaning formulations, having a viscosity of 2000 to 10,000 centipoise containing on a weight to weight basis: (a) 0.5 to 6.0 percent of hydrated aluminum silicate that is substantially free of inert mineral impurities; (b) 0.1 to 3.0 percent of an amphoteric material or a highly alkoxylated block copolymer; (c) 0.1 to 5.0 percent of a nonionic surfactant selected from the group consisting of polyoxyethylene derivatives of higher alcohols and polyethylene glycol ethers of linear alcohol; (d) sufficient acid to establish a pH in the range 0.9 to 3.5; (e) 5.0 to 50.0 percent of an abrasive; (f) 1.0 to 5.0 percent of a cleaning solvent; and (g) sufficient deionized water to make 100 percent.
