Definitions

  • the invention relates to liquid abrasive cleaning agents for hard surfaces which are largely transparent and contain more than 15% by weight of surfactant.
  • abrasive liquid cleaning agents for hard surfaces are usually milky, thick, viscous solutions. They are also well known to consumers as "scouring milk”, a name that also reflects the whitish, cloudy appearance of these products.
  • Liquid hand dishwashing liquids usually have a transparent appearance.
  • the clear agents in connection with the mostly used bright colors obviously have a particularly positive effect on the consumer, since this is associated with a particularly high cleaning performance.
  • a certain amount of surfactant is required to ensure good cleaning performance.
  • the international application WO 02/38720 describes clear surfactant-containing cleaning gels with macroscopic abrasive particles.
  • inorganic substances can be used as well as polymer granules or hard waxes.
  • the surfactant content is between 0.1 and 15%.
  • the gels are used to clean hard surfaces. Agents with surfactant contents above 15% by weight are not disclosed.
  • Patent specification EP 292 910 describes a stable, liquid, aqueous, abrasive cleaning agent for hard surfaces.
  • the abrasive particles should not scratch the surface to be cleaned.
  • Various plastics are proposed as abrasives, whereby the particles can have a size of 10 to 150 ⁇ m.
  • the cleaners described, which are referred to several times as "creamy”, are obviously abrasive milk, but transparent agents are not presented.
  • the agents are alkaline with a pH between 10 and 12.
  • WO 00/36078 relates to transparent or translucent liquid detergents for textiles in which encapsulated active ingredients are suspended using polymeric thickeners. These are enzymes, bleaches, perfumes, etc. liquid funds should be incorporated stably. In contrast, abrasives are not intended as ingredients.
  • German application DE-A 19918267 finally describes hand dishwashing detergents in which microcapsules with various active substances are suspended. An abrasive effect of these suspended particles is also not intended here, but the shell of the microcapsules opens up during use and releases the active ingredient contained therein.
  • Hand dishwashing detergents and other cleaning agents for hard surfaces that show good cleaning performance and contain an abrasive substance to remove heavily adhering soiling without scratching the surface to be cleaned during use, but at the same time having an appearance that is appealing to the consumer, have not yet been described.
  • the object of the present invention is therefore to provide a cleaning agent for hard surfaces which contains an abrasive, has good cleaning performance and is also visually appealing.
  • the invention therefore relates to an abrasive-containing liquid cleaning agent for hard surfaces which is largely transparent and has a surfactant content of more than 15% by weight.
  • “Largely transparent” in the sense of this invention is an agent which has a transmittance (transmission) for light of any wavelength in the visible range, ie between 400 and 800 nm, of at least 50%, measured in a cuvette with a layer thickness of 1 cm in Absence of dyes and abrasive particles.
  • the light transmittance is preferably above 70%, particularly preferably above 80%, in particular above 90%.
  • the optical impression is preferably that of individual, opaque particles stably suspended in a clear cleaning agent. Like the detergent surrounding them, these particles can take on any desired color, detergent and abrasive substance being colored the same or different.
  • the surfactant content of more than 15% by weight denotes the total amount of anionic, nonionic and amphoteric surfactants, based on the cleaning agent.
  • the present invention also relates to the use of the agent according to the invention as a hand dishwashing agent.
  • the agent fulfills a dual function, because on the one hand it can serve, especially in concentrated form, for the pre-cleaning of heavily soiled crockery, which may be contaminated with greasy grease or similar contaminants, with the abrasives contained contributing to the faster release of the contaminants. On the other hand, however, it is also suitable for washing normally soiled dishes in a customary manner by introducing them into a dilute aqueous cleaning liquor. Due to the surfactant content of more than 15% by weight, the agent has a good cleaning performance.
  • the detergents are just as good at cleaning other hard surfaces, for example made of glass, ceramic, plastic, enamel or metal, in the home and business.
  • other hard surfaces for example made of glass, ceramic, plastic, enamel or metal
  • kitchen and especially stove surfaces, ovens and other hard surfaces with partially stubborn and / or greasy soiling can be cleaned with agents according to the invention as well as bathroom surfaces, plastic furniture in the house and garden or windows and other glass surfaces, to name just a few options.

  • CTFA Cosmetic, Toiletry, and Fragrance Association
  • the Information CAS means that the following sequence of numbers is a designation of the Chemical Abstracts Service.
  • such abrasives can be substances which can be suspended as solids in the cleaning agent and which have a cleaning-supporting effect when the agent is used according to the invention. This is due to the abrasive effect of the particles, by means of which even more strongly adhering soiling can be removed and transferred to the cleaning liquor. At the same time, however, it is necessary that the surface to be cleaned is not scratched, roughened or attacked in any other way by the action of the abrasive material. Therefore, it is preferred that the particles have no sharp edges or tips. In particular, it is preferred if spherical or ellipsoidal, optionally also drop-shaped particles are used. With their spatial shape, in addition to the surface-protecting property, they also contribute to the positive optical impression of the agent according to the invention.
