Definitions

  • the present invention relates to aqueous bleaching compositions, more particularly to stable acidic thickened aqueous compositions comprising a source of persulfate salt. Said compositions find particular application in the cleaning of hard-surfaces, especially inclined hard-surfaces, such as toilet bowls and the like.
  • Bleaching/cleaning compositions comprising a source of active oxygen and formulated at low pH are particularly interesting for the cleaning of hard-surfaces, especially for the hygienic cleaning of sanitary fittings such as toilet bowls and the like.
  • EP-A-598 694 discloses acidic aqueous compositions comprising persulfate salts which are preferably in the form of an emulsion of nonionic surfactants.
  • compositions have not been found satisfactory as regards their residence time on the surface to be cleaned in particular if the surface is wet. Indeed, it is desired to formulate compositions having greater residence time on non-horizontal surfaces such as inclined wall of a toilet bowl when applied thereto, allowing thereby that said compositions perform their cleaning action for longer periods of time.
  • compositions known in the art that have the requisite viscosity characteristics.
  • most of the thickeners known in the art whilst allowing to effectively increase the viscosity of aqueous acidic compositions, do have some disadvantages in use.
  • thickeners like nonionic surfactants (nonyl phenol ethoxylates) or quaternary ammonium compounds have the disadvantage that they require to be used at high levels to achieve satisfactory viscosity, thus making them expensive to use.
  • some thickeners show significant instability in acidic medium, especially in acidic medium with hydrogen peroxide, or a source thereof, like monopersulfate.
  • some thickeners are easily oxidizable by sources of active oxygen, like monopersulfate, in aqueous acidic compositions, leading thereby to a loss of the total amount of active oxygen which would otherwise be available to perform bleaching action on the surface to be cleaned.
  • some thickeners do not allow to formulate acidic aqueous compositions comprising a source of active oxygen with satisfactory chemical stability for long storage periods.
  • It is a further object of the present invention to formulate acidic aqueous compositions comprising a source of active oxygen with high thickening at low total thickening surfactant level.
  • an acidic aqueous composition comprising a source of persulfate salt and, as the thickening system, a quaternary ammonium compound together with a short chain amine oxide (C6-C10). More particularly, it has unexpectedly been found that the addition of a small amount of a short chain amine oxide to a quaternary ammonium compound, as the thickening system, in an acidic aqueous composition comprising a source of persulfate salt allows to formulate highly thickened aqueous acidic compositions as compared to the use of only said quaternary ammonium compound, as the thickening system, i.e.
  • a thickening system being free of any short chain amine oxide.
  • the present invention allows to use low level of total thickening surfactant to achieve a given viscosity for an acidic aqueous composition comprising a source of persulfate salt.
  • a lower level of total thickening surfactants quaternary ammonium compounds and short chain amine oxides
  • quaternary ammonium compounds and short chain amine oxides is sufficient in the present invention, as compared to the level of quaternary ammonium compound which would otherwise be required to obtain the same thickening effect when used alone, in absence of any short chain amine oxide.
  • the thickening system of the present invention exhibits good stability in acidic medium and in presence of strong oxidants like persulfate salt. Indeed, the decomposition of said persulfate salt, is reduced with the thickening system of the present invention as compared to other surfactant blends like for instance alkylethoxylated alcohols. In other words, persulfate salt in thickened aqueous acidic compositions of the present invention are chemically stable for longer periods of storage.
  • An advantage of the present invention is that the stable thickened aqueous acidic compositions comprising a source of active oxygen according to the present invention are less sensitive to the presence of perfumes.
  • the thickening system of the present invention allows to formulate stable acidic aqueous compositions comprising a source of persulfate salt and still having high viscosity, despite the presence of perfumes, even at high levels.
  • high levels of perfume are known to have a general tendency to significantly decrease composition viscosity by changing micellar aggregation.
  • compositions are efficient on various surfaces to clean various soils and stains. Additionally, said compositions when used to treat hard surfaces, especially toilet bowls, exhibit outstanding soil discoloration, soil solubilization and emulsification properties together with a germicidal action, this when used both neat or diluted.
  • a further advantage is that the present invention allows to formulate compositions which are clear, as opposite to clouded, and thus well accepted from a consumer view point. Also the present invention allows to formulate compositions that are Newtonian. By “Newtonian” it is meant herein a composition which has the same viscosity within a very wide range of applied shear stresses.
  • EP-A-275 043 discloses an acidic cleaner for aluminium surfaces containing a peroxide, acids, a C12-C22 alkyl dimethylamine oxide. Said cleaner has a pH at most 2.
  • EP-A-275 043 discloses cationic surfactants as optional ingredients but no specific compounds of this class of surfactants are mentioned, let alone quaternary ammonium compounds.
  • EP-A-265 979 discloses acidic thickened aqueous cleaning composition

  • the present invention uses quaternary ammonium compounds together with short chain amine oxides (C6-C10) as the thickening system.
  • C6-C10 short chain amine oxides
  • EP-A-188 025 discloses aqueous stable thickened low-pH bleaching compositions comprising an inorganic peroxy compound, a strong acid and a thickening.; syrfactant.

  • EP-A-188 025 teaches to use as a thickening surfactant one of these surfactants.
  • this patent application teaches to preferably use long chain amine oxides.
  • none of the compositions exemplified comprises, as the thickening system, a quaternary ammonium compound together with an amine oxide, let alone a quaternary ammonium compound together with a short chain amine oxide.
