Definitions
- the present invention relates to a cleaning composition for hard surfaces for household use, and to a method for cleaning hard surfaces using the composition.
- Cleaning liquids for household surfaces are well known. These liquids often contain ingredients that have the purpose to facilitate the easy removal of stains and soils from hard surfaces while abrasion and scratching of the surface should be as low as possible.
- Calcium carbonate is often used as an abrasive in such cleaning liquids, and tough soil on surfaces may be removed via these liquid abrasive cleaners.
- Calcium carbonate (CaCO 3 ) of known particle size, in the calcite crystal form, is used as the abrasive in current commercially available liquid abrasive cleaners. This abrasive is a highly effective tough soil remover, but with this presents the unavoidable potential for surface damage when cleaning. Increasing the level of calcite in the formulation improves cleaning, but also increases surface damage.
- the use of conventional CaCO 3 in cleaning compositions easily results in an undesired high viscosity, because relatively high levels of CaCO 3 are used to provide efficient cleaning.
- EP 0 103 325 A1 discloses a liquid scouring cleaning composition
- a liquid scouring cleaning composition comprising an abrasive powder, for example precipitated calcium carbonate (aragonite).
- aragonite precipitated calcium carbonate
- WO 2009/040597 discloses a cleaning composition for hard surfaces, containing solid inorganic microparticles having a particle size of from 0.5 to 5 micrometer, a surface area of from 10 to 50 m 2 /g and a crystallinity degree lower than 50 percent.
- the inorganic microparticles may be carbonates, and in one of the examples carbonate-substituted non-stoichiometric hydroxyapatite is used. These particles have the advantage that the abrasiveness has decreased.
- US 2010/0263693 A1 discloses hard surface treatment compositions, wherein the particle size of an abrasive agent ranges from about 1 to 1000 micrometer, more preferably from about 10 to 100 micrometer.
- Abrasive agents that will not scratch glass or ceramic surfaces are preferred, and these include calcium carbonate, siliceous chalk, diatomaceous earth, colloidal silicon dioxide, sodium metasilicate, talc, and organic abrasive materials.
- WO 2011/087733 A1 discloses a liquid cleaning composition comprising abrasive particles which have been defined based on roughness and hardness.
- the abrasive particles preferably comprise polymeric particles, e.g. polyurethane.
- the particles in the form of platelets are coated.
- the particles in the form of platelets such as naturally observed for example in mica or clay particles, normally have two relatively large flat dimensions (length and breadth) and a relatively thin third dimension (depth).
- the coating preferably a metal oxide coating, is visible on the sheets when using electron microscopy, as known in the art.
- the coated particles in the form of platelets preferably coated mica or coated clay particles or mixtures thereof, are introduced into a liquid cleaning and/or polishing composition, either totally or partially replacing the conventional ground calcium carbonate (or chalk), a greatly reduced damage profile is observed after use on the surface.
- a damaged surface may even be repaired or polished when the composition of the invention is used.
- a surface is considered repaired or polished if the scratches of a possible previously treatment are less visible, and the original gloss is restored at least to some extent. This is, at least partly, effected by treatment of a surface with a composition of the invention.
- the present invention provides a composition for cleaning and/or polishing of surfaces, comprising surfactant and coated particles in the form of platelets, wherein the composition is liquid at room temperature, the composition further comprising calcium carbonate.
- the present invention provides a method for cleaning and/or polishing a surface, wherein a composition according to the first aspect of the invention is used.
- the expressions '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.
- a liquid composition refers to a composition that will flow under the force of gravity.
- the viscous modulus G" preferably is higher than the elastic modulus G'. This is in contradiction of pastes or gels, which keep their shape under the force of gravity.
- coated particles in the form of platelets are present in a liquid cleaning and/or polishing composition.
- the particles suitably comprise particles of for example Al 2 O 3 , SiO 2 , glass, calcium aluminum borosilicate, mica, clay, or mixtures thereof, more preferably mica, clay or mixtures thereof.
- the coated particles in the form of platelets preferably comprise coated mica particles, coated SiO2 particles or coated clay particles, or mixtures thereof.
- coated particles in the form of platelets are coated mica particles, coated clay particles or mixtures thereof.
- the composition of the invention comprises particles in the form of platelets.
- Platelets represent a shape which is easily recognised by the skilled person. Platelets normally have two relatively large flat dimensions (length and breadth) and a relatively thin third dimension (depth). "Sheets" or “flakes” are considered synonyms for "platelets”.
- Preferred materials in the present invention naturally show a platelet form when the particles are present at the microscopic size one would apply them in a cleaning or polishing composition. For example, mica or clay particles exhibit a platelet like morphology.
- the coated particles in the form of platelets preferably have a length (longest dimension of the particle) ranging from 2 to 200 micrometer, more preferably from 5 to 100 micrometer, even more preferably from 10 to 60 micrometer. A range of from 3 to 50 micrometer may be preferred, or even from 4 to 40 micrometer. Especially in case the coated particle is mica, or SiO 2 the length is preferably in the range of 5 micrometer to 60 micrometer. A range of from 3 to 50 micrometer may be preferred, or even from 4 to 40 micrometer. Especially in case the coated particle is clay, the length is preferably in the range of 5 micrometer to 200 micrometer. These sizes result in optimal polishing effects.
- the particles preferably have a depth (shortest dimension of the particle, perpendicular to the length and breadth) ranging from 0.1 to 3 micrometer, preferably from 0.5 to 2 micrometer, even more preferably of from 0.75 to 1.5 micrometer. Most preferably, of from 0.5 to 1 micrometer. Least damage and optimal polishing effects to the treated surface is obtained by coated platelets which have an average depth according to these preferred ranges.
- the lengths and depths as mentioned above can be combined, e.g. preferably the coated particles have a length of 2-200 micrometer and a depth of 0.1 to 3 micrometer.
- the coated platelet particles preferably the mica particles
- the term 'crystal' means an essentially fully dense solid composed of atoms arranged in an orderly repetitive array bounded by plane surfaces which are the external expression of internal structure. Particle morphology and structure may be determined by standard techniques known to those skilled in the art such as scanning electron microscopy (SEM). SEM is an imaging and analysis technique based on the detection of electrons and X-rays that are emitted from a material when irradiated by a scanning electron beam. Imaging allows the user to distinguish between primary particle and agglomerate sizes.
- Scanning electron microscopy is a particle counting technique and produces a number-weighted size distribution. Accordingly the dimensions quoted herein for particle length and depth will generally represent average values over a population of particles, more specifically the D[1,0] number-length mean of the particle length or the particle depth respectively.
- the particles as used in the present invention preferably have a hardness of between 2 and 7 Moh, preferably between 2 and 6 Moh, more preferably of between 2 and 5 Moh, even more preferably of between 2.5 and 3.5 Moh.
- Moh values are based on the hardness of the coated particles.
- the Mohs scale of mineral hardness is known to the skilled person and characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material.
- the Moh value is a result of the crystal material as well as the crystal structure.
- the mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having close to perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.
- the mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having close to perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms.
- the main mica groups are:
- mica For the purposes of cleaning and polishing the choice of mica is not important. Muscovite and phlogopite are commercially best available and therefore preferred.
- the present invention describes the use of coated platelet particles. It was surprisingly found that using coated platelet particles, the particles provided highly increased polishing capabilities, compared with non-coated particles. In fact, the non-coated particles showed little polishing effect, compared to the coated particles.
- the coating comprises preferably particles which are spherical particles, like metal oxide particles.
- the hardness of the coating particles is preferably of between 5 and 7 Moh. Preferably the hardness of the coating particles is higher than the hardness of the platelet particles that are to be coated.
- the coated particles are particles coated with metal oxide.
- the coating particles can be from a metal oxide with a high refractive index, e.g. for coloring purposes.
- metal oxides qualify as high refractive index metal oxides and hardness of coating particles, and they can be purchased for example from Merck or ECKART.
- the particles are coated with TiO 2 , Fe 2 O 3 , ZrO 2 , Cr 2 O 3 , or mixtures thereof. Also other metal oxides can be used.
- the particles are coated with TiO 2 .
- the platelet particles are preferably coated with metal oxide, preferably in the form of metal oxide particles.
- the size of the coating particles, e.g. the metal oxide particles is in the range of from 30 nanometer to 200 nanometer.
- Coated platelet particles normally exist in the art and are commercially available.
- coated mica is an ingredient which is known in the pearlescence paint art. It can for example be bought under the trade names Balance BlueTM, Red LustreTM, Silver LustreTM or Silver FineTM, as produced by Merck for food grade use. Non-food grades may also be used for cleaning and polishing applications, for example Timiron SupersheenTM.
- Coated SiO 2 is offered by Merck under the trade names Xirona Nordic Sunset and Xirona Indian Summer.
- the polishing effect can be measured by using the test as described in the Examples.
- the recovery as calculated according to the formula in the Examples, is preferably higher than 50 %, more preferably higher than 60%, more preferably higher than 70%, even more preferably higher than 80%, more preferably higher than 90%.
- the concentration of the coated particles in the form of platelets ranges from 0.2 to 40 wt%, preferably of from 1 to 40 wt%, preferably from 1 to 30%, more preferably of from 2 wt% to 30 wt%, more preferably of from 5 wt% to 30 wt%, more preferably, it ranges from 2 to 20%, preferably from 5 to 15%, based on the total weight of the composition.
- the concentration of coated mica particles preferably ranges from 0.2 to 40 wt%, preferably of 1 to 40 wt%, preferably from 1 to 30%, more preferably, it ranges from 2 to 20%, preferably from 5 to 15%, based on the total weight of the composition.

- the concentration of coated clay particles preferably ranges from 0.2 to 40 wt%, preferably of 1 to 40 wt%, preferably from 1 to 30%, more preferably, it ranges from 2 to 20%, preferably from 5 to 15%, based on the total weight of the composition.
- the composition only contains coated particles in the form of platelets, preferably only coated mica particles, coated clay particles or mixtures thereof, as abrasive material.
- coated particles are used in combination with calcium carbonate, e.g. CaCO 3 in the calcite crystal form.
