  • Patent number: 5624891
    Abstract: A thickened composition comprises:(a) an active cleaning component, present in a cleaning effective amount; and(b) a thickening system comprising an alkali metal salt of an N-alkyl-N-acyl amino acid and a mixture of myristyl/cetyl dimethyl amine oxides. In a preferred embodiment, the cleaning composition comprises an alkali metal hypochlorite and a strong base comprising an alkali metal hydroxide and an alkali metal silicate. The thickened compositions are useful as hard surface cleaners and particularly useful as drain opening compositions.

  • Patent number: 5549842
    Abstract: Thickened aqueous hypochlorite compositions comprises (a) an alkali metal hypochlorite, (b) a tertiary amine oxide with one alkyl group having from 10 to 16 carbon atoms and the two other alkyl groups having from 1 to 3 carbon atoms, (c) an alkali metal salt, (d) a pH stabilizer to bring the pH to a level of 11 or higher, (e) a C.sub.10 -C.sub.16 alkali metal sarcosinate, and (f) C.sub.10 -C.sub.14 straight chain alkyl benzene sulfonate. The molar ratio of (b):(f) is from about 5:1 to about 11:1 and is adjusted so that the viscosity of the composition is between 231 and 402 cps. The compositions are useful for general cleaning purposes, particularly bathrooms and toilet bowls, and also as a laundry additive.
