Definitions

  • the present invention relates to a cleaning composition for hard surfaces, comprising at least a specific polymer and a surfactant that is useful against soil, especially greasy soil.
  • the invention also relates to a method for cleaning a hard surface wherein said cleaning composition is used and wherein a next time cleaning benefit is obtained.
  • compositions which comprise one or more surfactants and, possibly, also pH adjusters like citric acid or sodium salts of citrate.
  • Such compositions may further comprise additional components for targeting specific stains or soils.
  • the cleaning compositions can be applied in diluted (in water) or undiluted form, in a spray, or rubbed using a cloth and any other convenient way.
  • the cleaning composition may be rinsed from the surface after the cleaning. It would be advantageous if the hard surface to be cleaned could be treated with a material which would assist in easier removal of soil and/or stains during subsequent cleaning. This is referred to as the next time cleaning benefit.
  • Soils on hard surfaces can become more difficult to remove when not cleaned soon after deposition. When not cleaned promptly, soils can become more adherent to surfaces, more viscous and generally tougher, and require more effort to clean. While not being bound by theory, this more difficult removal of soils can arise from the effects of drying out of soils, from chemical changes in soils, from reactions of soils with environmental agents such as oxygen, etc. Some soils are more susceptible than others to toughening reactions and processes. Soils comprising or containing chemically unsaturated oils and fats can become very tough and difficult to clean over time, especially when exposed to elevated temperatures. Even light can cause such fatty soils to toughen over time.
  • Hard-surface cleaning compositions may be either acidic or alkaline. Acidic compositions often contain citric acid, sorbic acid, acetic acid, formic acid, maleic acid, adipic acid, lactic acid, malic acid and glycolic acid. Acidic cleaners are generally used for removing acid sensitive soil, such as limescale. For removal of fatty soil alkaline compositions are generally preferred.
  • EP-A 0859046 describes a liquid hard-surface cleaning composition having a pH above 9 and comprising a copolymer of N-vinylpyrrolidone and alkylenically unsaturated monomer or mixtures thereof.
  • the examples describe compositions comprising surfactants and polymers (PolyquatTM 11; LuviskolTM 73W; PEG DME-2000).
  • EP-A 1927651 describes a liquid composition having, a pH between 3 and 7, comprising: non ionic surfactant; amine oxide; a glycol ether solvent; a chelant; and a cationic polymer.
  • WO-00/58228 discloses a composition for rust and/or corrosion removal that contains a reducing agent, a chelating agent and a surfactant. Said composition which may also contain a polymer dispersant, is said to form stable protective coating after cleaning.
  • US 2008/233061 discloses structured surfactant compositions which may optionally contain polyglyceryl methacrylate.
  • WO-2005/030282 discloses the use of a coating composition comprising polymeric micelles, wherein the polymer has an ionic block and a neutral hydrophobic block, for surface modification or surface treatment. More particularly, this document discloses the use of said composition for preventing bacteria proliferation, disinfecting, suppressing odors or for providing easy-cleaning or soil-release properties.
  • WO-2010/003783 describes a laundry detergent composition comprising:
  • a further objective is that said benefit can be obtained across the pH-spectrum, with both acid and alkaline cleaning compositions. It is yet another object to achieve a next time cleaning benefit without leaving residues of compounds that may be considered to be harmful to the consumer.
  • the inventors have now surprisingly found that one or more of these objects can be achieved using the cleaning composition of the invention which comprises a surfactant and a specific type of polymer.
  • the present invention provides an aqueous hard surface cleaning composition according to claim 1.
  • the present invention provides method for cleaning a hard surface and obtaining a next time cleaning benefit for said surface according to claim 5.
  • the present invention provides the use of the aqueous hard surface cleaning composition for cleaning a hard surface and obtaining a next time cleaning benefit for said surface.
  • soil and stain 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 phrase "next time cleaning benefit" as used herein refers to an improved ease of removal of soil after re-soiling of a hard surface cleaned using the method of the present invention.
  • This improved ease may be indicated by an increased amount of soil being removed from a hard surface using a certain fixed cleaning effort (e.g. the same no. of wiping actions using the same force per wiping action).
  • Evidence of this type of improved ease of the removal of soil is shown in the examples.
  • the improved ease of the removal of soil may also be indicated by the lower effort (e.g. less wiping actions, less force per wiping action or a combination thereof) necessary to reach a similar level of soil removal.
  • the improved ease of removal may also be indicated by a combination of the above-mentioned effects (i.e. increased amount of soil removed with less effort).
  • the method of the invention includes the step of removing soils and stains, preferably mobile soils.
  • mobile soils as used herein is intended to mean soils that are not significantly cross-linked or dried-out, and thus are able to be moved on the surface with a dry cloth. Such mobile soils are e.g. greasy soils.

  • the present invention provides a method for cleaning a hard surface, and obtaining a next time cleaning benefit, the method comprising the following sequential steps:
  • the soil or stain is a soil or stain containing fatty material, which has not undergone a significant toughening reaction and is, therefore, still mobile (see the above definition of "mobile soil”).
  • Treatments are evaluated on large pieces of worktop laminate (Fundamentals matt white ex Formica). Said test pieces are pre-cleaned by wiping them with ethanol.
  • Each large piece of worktop laminate can fit 4x A4 treatment patches, which are evenly spaced across the laminate and do not touch each other.
  • 2 ml of the test solution is applied to the surface of each A4 patch and distributed uniformly over the area thereof using a dry perforated viscose cloth (e.g. J-cloth).
  • the treatment is allowed to dry naturally for 5 minutes.
  • the surface is rinsed with water for 30 seconds using a shower head with flow rate fixed at about 5-6L/minute.
  • the soil is prepared by first making a large batch (ca. 2kg) without carbon black. This is sheared using a Silverson mixer for 60 minutes or until ca. 45°C. The soil is left to cool overnight. Then, before use a smaller batch of the soil is taken, carbon black added, and sheared again for 30 minutes or until ca. 45°C using a Silverson mixer at a lower shear rate.

  • the cleaning is carried out on an ergonomics rig and continued until the trained operative designates the patch completely clean (which means that all visible and tactile evidence of the soil has been removed), or for at most 2 minutes. Subsequently, the effort to clean is recorded. If not all of the soil is removed during the maximum time of 2 minutes, then the patch is declared "not clean".
  • test formulations were prepared by stirring together all of the ingredients apart from the pH adjuster and a small amount of the water (5%). After all the ingredients had dispersed, the pH was adjusted using the relevant pH adjuster and the balance of the formulation made up with water.
