Definitions

  • the invention relates to a method and composition for facilitating the removal of soil contaminants from solid surfaces e.g. the removal of soap scum from bathroom hard surfaces such as ceramic tiles.
  • FR-A-2 639 353 describes coating a solid surface with a composition comprising a mixture of polymers to render the surface waterproof, oil-resistant, stain-resistant and self-cleaning.
  • a shortcoming of this approach is that the nature of the adhesive bond between a soil contaminant and the surface varies depending on the composition of the contaminant. For example, adhesion could result from electrostatic, dispersion, dipole/dipole, hydrophobic or hydrogen bond interactions as well as from rugosity effects. For contaminants which are a mixture of different components, adhesion usually occurs through a number of different adhesive bonds. Furthermore, solid surfaces are rarely, if ever, smooth and soil contamination can occur by physical entrapment.
  • composition of soap scum which is a common bathroom soil is a mixture of ionic, hydrophilic and hydrophobic components.
  • a scum could form a variety of adhesive bonds to typical household hard surfaces such as metals, plastics, ceramics, glass and glazed surfaces.
  • An object of the invention is to provide a method of facilitating the removal of soil contaminants from a solid surface which does not require chemically modifying the surface to render it less prone to soil adhesion.
  • a method of facilitating the removal of soil contaminants from a solid surface comprises washing the surface with a liquid composition characterised in that the liquid composition comprises a material which is deposited on the surface during washing and upon drying forms a layer adhered to the surface, said material having a cohesive strength such that at least the outermost surface portion of the layer is removable by further washing.
  • a liquid composition for cleaning solid surfaces comprising one or more cleaning agents characterised in that the composition comprises a material capable of being deposited on the surface during cleaning and of forming a dried layer adhered to the surface, said layer having a cohesive strength such that at least the outermost surface portion of the layer is removable by washing.
  • Figure 1 is a graph showing results achieved using the method of the invention.
  • the method of the invention can be used for any solid surface. It is particularly applicable to hard surfaces found in the household for which a variety of cleaning compositions are known, especially bathroom cleaning compositions. Typical household surfaces include metal, plastics, ceramic, fibreglass, enamel, glass and glazed surfaces.
  • the liquid composition used in the invention is preferably an aqueous composition in which the other components are dissolved or dispersed.
  • the material which is deposited on the surface to form a layer of low cohesive strength is preferably a film-forming polymeric material.
  • the cohesive failure of the polymeric material can be controlled by choosing suitable molecular weight polymers.
  • the layer is at least partially water-soluble.
  • the layer is uncharged over a reasonable pH range.
  • the layer is preferably clear.
  • Examples of materials which have been successfully used to form the layer include polyvinylpyrrolidone (PVP), gelatin and saponin.
  • the deposited layer provides a weak link between the adhered soil contaminants and the solid surface. Hence, the soil contaminants can be removed easily by washing. It is possible to provide treated surfaces with resistance to multiple soiling since the layer can be made to become thinner after each washing with sufficient of the layer remaining for further protection. Upon washing, the layer strips partially from the surface to leave a thinner, but clean surface. In the preferred mode of operation, this surface is invisible to the naked eye.
  • the material from which the low cohesive strength layer is formed can be incorporated in a cleaning composition so that the layer can be formed on the solid surface during cleaning.
  • Existing cleaning compositions can be modified in this way provided that the incorporation of the material has no adverse interactions with the other components.
  • the cleaning composition comprises one or more components known in the art such as detergents, chelating agents, water-miscible organic solvents and pH control agents.
  • composition of the invention may be incorporated into other materials such as quaternary nitrogen or phenolic antimicrobial agents.
  • the invention is further illustrated by way of example as follows.
  • Standard glazed black ceramic tiles were wipe-coated with a 5%w/w PVP ( ⁇ 40k MW) aqueous solution and allowed to dry.
  • a standard bathroom soil was sprayed from an acetone/water mixture onto the treated tiles and allowed to dry.
  • the composition of the bathroom soil (soap-scum) used is a mixture of ionic, hydrophilic and hydrophobic components as follows: component %w/w hard water 95.54 bar soap 3.90 shampoo 0.35 sebum 0.15 clay soil 0.06
  • the tiles were then "aged” by heating at 1100C for ⁇ 2 hours. After cooling to room temperature, the tiles were cleaned in water with a brush under standard conditions. Measurements (10x) were taken with a simple reflectometer (visible light) from different points of the area cleaned by the brush. The average (mean) was compared with that from a control untreated tile, which had been through the soiling process, and an untouched reference.
  • Table 1 below provides data showing the average percentage soil removal from PVP-treated and untreated tiles after one or more cycles of soiling and cleaning operations.
  • Table 1 Conditions % Soil removal* Untreated PVP-treated Reference 80.9 N/A Soiled & cleaned 1x 39.8 57.7 Soiled & cleaned 2x 0.0 78.5 Soiled & cleaned 3x 1.9 51.0 Soiled & cleaned 4x 2.0 60.5 * % soil removals are calculated from reflectance readings
  • Table 2 Coating Material wt. % in water Control 0 Digel (gelatin) 2.0 PVP ( ⁇ 10k MW) 5.0 Saponin 1.0 Cetyl pyridinium bromide (CPB) 0.1
  • Standard glazed black ceramic tiles were prepared and subjected to soiling/cleaning cycles in accordance with the procedure of Example 1.
  • the cleaning results after three cycles of soiling/cleaning are shown in Figure 1.
  • PVP was incorporated into a bathroom hard surface cleaner to provide the composition given in Table 3 below.
  • Table 3 Formulation % by weight 1.
  • Hard surface cleaner 99.0 EDTA 2%
  • NeodolTM 23.6 0.5%
  • Sodium meta silicate 0.25% Water to 100% 2.
  • PVP ( ⁇ 10k MW) 1.0 (NeodolTM 23.6 is a linear C12-C13 alcohol ethoxylate nonionic surfactant)
  • Standard glazed black ceramic tiles were wiped with 0.5g of the above composition until dry. About 0.01g of the composition is deposited on each tile.
  • Tiles were coated with soap scum in accordance with Example 1. The coated tiles were allowed to dry in air for 30 minutes and cured for 45 minutes at 85°C. The tiles were cooled and rinsed. A comparison was made with untreated tiles used as controls. The results are shown in Table 4 below. Table 4 Tile No. Treatment Removability of Soap Scum 1 Treated 100% removed with water rinse Control Untreated No removal even after 15 rubbing strokes and cold water rinse 2 Treated 90% removal Control Untreated 0% removal 3 Treated 90-100% removal 4 Treated 90-100% removal
  • the object of the example is to determine if the coating provided by the composition of Example 3 is effective even after rinsing with water.
  • a test tile was prepared as in Example 3. The tile was treated with soap scum soil, air dried and then cured for 15-20 minutes at 90°C. A portion of the tile was rinsed under cold water and then resoiled and rinsed. The results are shown in Table 5 below. Table 5 Test No. Treatment % Soil Removal 1 Soiled/rinsed (1x) 100% 2 Soiled/rinsed (2x) 40% 3 None (Control) 0%
