Definitions

  • the present invention relates to methods for cleaning hard surfaces, and to compositions suitable for that purpose, involving the application of malonic acid to such surfaces.
  • Household surfaces are normally cleaned using compositions which contain one or more ingredients which assist in removal of fatty/oily/greasy soil and/or any visible staining such as from associated solid debris.
  • Such compositions may be applied as diluted or concentrated aqueous solutions e.g. with a cloth, wipe or other implement or as a spray, such as a trigger spray dispenser or other aerosol applicator, optionally followed by rinsing.
  • compositions may be either acidic or alkaline.
  • Acidic compositions often contain carboxylic acids which may be mono-, di- or polycarboxylic acids, such as citric acid, sorbic acid, acetic acid, formic acid, maleic acid, adipic acid, lactic acid, malic acid and glycolic acid. Unless the type of soil specifically requires the presence of a strong mineral acid, such acids are generally not recommended because of the damage they may cause on delicate and acid- sensitive surfaces .
  • Acidic cleaners are generally used for removing acid sensitive soil, such as limescale. For removal of fatty soil alkaline compositions are generally preferred. The use of malonic acid in acidic hard surface cleaners is known in the art. In UK 2,392,167 a composition is described comprising malonic acid. The composition as described is formulated as an acidic composition and intended for lavatory cleaning.
  • WO00/32737 and WO00/27983 a cleaning process is described, using acids with pKa>3.5, to prevent damage to enamel surfaces.
  • Malonic acid is an optional ingredient in the composition and is described as chelating agent. Although the pKa of malonic acid is 2.8, no reference is made to that fact .
  • machine dish washing compositions comprising bicarboxylic acids, such as malonic acid, for corrosion inhibition.
  • the present invention provides a method for removing soil or stains from a hard surface, the method comprising the steps in sequence of:
  • a and A' are independently selected from -H, alkali and alkaline earth metal ions, quaternary ammonium ions, trivalent metal ions, and organic cations, and wherein R is selected from -H or Ci-C 4 alkyl or a combination of such compounds;
  • the present invention further provides a liquid hard surface cleaning composition
  • a liquid hard surface cleaning composition comprising: (a) 0.01 to 10% by weight of a compound according to the general formula 1 above; and
  • soil and stain as used herein generally comprise all kinds of soils and stains generally encountered in the household, either of organic or inorganic origin, whether visible or invisible to the naked eye, including soiling solid debris and/or with bacteria or other pathogens.
  • the method and compositions according to the invention may be used to treat fatty or greasy soil and stains, more specifically those caused by natural fat or oil.
  • malonic acid exerts its effect by depositing on the surface and exerting an influence on soil or stains subsequently depositing on the surface such that such soil or stains are prevented from getting strongly attached to that surface. Therefore in a preferred embodiment of the invention a compound according to formula 1 (hereinafter briefly referred to as "malonic acid”) is applied to the surface as a solution, preferably an aqueous solution, which is thereafter left to dry on the surface.
  • Step (c) of the method is advantageously effected using a hard surface cleaning composition comprising malonic acid again so that soil or stain is removed and new malonic acid is applied, effectively constituting step (a) of a subsequent process according to the first aspect of the invention.
  • Step (c) is optionally followed by a rinsing step, preferably with water.
  • Malonic acid proper may be derived from sugar beet and can therefore be classified as a natural material, something that is increasingly important to present day consumers.
  • malonic acid is meant to include malonic acid derivatives and salts or mixtures of these compounds as defined above by formula 1.
  • R is selected from -H or -CH 3 or -CH 2 CH 3 .
  • the present invention may also deliver other benefits such as improved surface feel (e.g. smoothness) during and/or after cleaning, olfactory benefits (e.g. reduction in rancid odour) before cleaning, less surface corrosion and less noise during cleaning.
  • Further aspects of the present invention comprise use of malonic acid or compositions containing malonic acid, for obtaining one or more of these other benefits in a hard surface cleaning operation and/or use of malonic acid in the manufacture of products for delivering one or more such other benefits.
  • malonic acid does not discolour, which is a particular advantage for a cleaning method according to the invention.
  • compositions and articles according to the present invention are useful for treating any household surface such as found in kitchens and bathrooms, including cooker tops, extractor fans, tiles, floors, baths, toilets, wash basins, showers, dishwashers, taps, sinks, work surfaces.
