Definitions

  • the present invention is in the field of hard surface treatment compositions.
  • the invention particularly relates to hard surface treatment compositions that provide easier cleaning upon the subsequent cleaning.
  • Hard surfaces in the home or office are usually cleaned using liquid compositions which comprise one or more surfactants and possibly also pH adjusters like citric acid or sodium salts of citrate.
  • the cleaning compositions can be applied in diluted (in water) or undiluted form, in a spray, or rubbed using a cloth or 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 a 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. As well as environmental factors, the processes of toughening of soils can be affected by the nature and composition of the surface on which the soil is located.
  • WO 02/18531 discloses a method for cleaning hard surfaces, wherein the surface is treated with an antioxidant, followed by allowing the surface to become dirty, and subsequently cleaning the surface.
  • the treatment of the surface with the antioxidant prior to the soiling leads to easier removal of the soil during the subsequent cleaning step.
  • the antioxidant may be present in a cleaning composition, or in a rinse composition that is applied after the cleaning.
  • cleaning compositions comprising antioxidants, preferably at a concentration of 0.1-10 % by weight, are disclosed. Tannic acid was exemplified to be notably efficient.
  • WO 2006/108475 A1 discloses a method for removing fatty soil from a hard surface, the process comprising the sequential steps of (a) treating the hard surface with a liquid cleaning composition; (b) allowing the fatty soil to deposit; and (c) cleaning the surface to remove the fatty soil.
  • WO 2010/069731 A1 discloses a method and a composition for treating a fabric substrate to render the substrate repellent to various soils and stains and also hydrophobic. There is disclosed a method of treating the substrate by using a composition of soap and a water soluble trivalent or tetravalent metal and which composition has a pH of less than 6 maintained by the addition of a pH modifying agent.
  • Self cleaning surfaces are disclosed in WO04037944 A1 , wherein a process and a composition are disclosed for producing surfaces that are self-cleaning by water, and in particular, there is disclosed an aqueous system for forming transparent self-cleaning surfaces.
  • an aqueous mixture comprising nano particles having a particle size of less than 300 nanometers and a surface modifier selected from the group consisting of water-soluble hydrophobic surface modifiers and water-dispersible hydrophobic surface modifiers capable of forming a continuous film from an aqueous solution is provided.
  • the aqueous mixture is applied to a surface, and a self-cleaning transparent coating is formed on the surface upon water evaporation.
  • the aqueous mixture is essentially free of organic solvents other than coalescing solvents.
  • the antioxidants as disclosed by the prior art also may suffer from disadvantages. Consumers may regard residues of antioxidants and/or nano particles on the hard surfaces in e.g. kitchen and bathroom to be harmful and undesired.
  • Microemulsion based cleaners comprising metal soaps and silicon material are disclosed in the art (e.g. US 5,759,983 and US 5,741,760 ). However, these compositions do not provide the required stain repellence due to lack of hydrophobicity of the surface when the composition is applied.
  • surfactants render surfaces hydrophilic, which make them more susceptible to aqueous stain deposition, rather than aqueous stain repellence.
  • poly aluminium chloride and a soap in combination with a poly vinyl alcohol and non-ionic or cationic surfactant provides both good cleaning and good stain/soil repellence.
  • the present invention provides a hard surface treatment composition
