Definitions
- the invention relates to a cleaning agent for hard surfaces, which can be used in particular for cleaning the outer surfaces of vehicles in car washes. It is particularly suitable for cleaning the vehicle surfaces in a way that is gentle on paintwork, since mechanical cleaning aids such as brushes can be dispensed with.
- the cleaning effect is based in part on the fact that the cleaning agent contains fibers, preferably cellulose fibers. Dirt and dust particles bind to these on the outer surface of the vehicles and are gently removed when the detergent is rinsed with water without scratches in the paint.
- WO 94/19441 discloses a cleaning agent which is preferably applied in the form of a foam to the surface to be cleaned and is then rinsed off with water without mechanical aid. This significantly reduces scratch formation.
- the cleaning agent contains a water-soluble cellulose derivative as an essential component. It is combined with a second alkaline cleaning component immediately before use and sprayed onto the surface.
- the combined cleaning mixture can additionally contain fibers such as cellulose fibers. In a preferred embodiment, however, after the fiber-free cleaning agent has been applied to the surface, a fiber suspension is additionally sprayed onto the surface.
- this process has the disadvantage that, in addition to the usual active cleaning components, a water-soluble cellulose derivative must be provided. Its production is energy-intensive, possibly polluting the environment and increases the cost of the cleaning agent. Furthermore, the cleaning process is expensive in terms of equipment, since at least 2, if a fiber suspension is used separately, at least 3 product containers must be provided. Furthermore, lines and dosing devices are required to mix the individual components before application or to apply them one after the other to the vehicle surfaces.
- the object of the invention is to provide a cleaning agent for hard surfaces and a cleaning method with which dirt and dust particles can be gently removed from the surfaces.
- the cleaning agent should contain inexpensive components and should be sold and used as a one- or at most two-component system.
- the invention relates to a cleaning agent for hard surfaces, containing water and a) 0.1 to 20% by weight of fibers with a length between 0.5 and 5 mm, b) 0.05 to 5% by weight Thickeners, c) if necessary, so much alkalizing agent that the pH is in the range from 7 to 14.
- Alkalizing agents c) which may be used are, for example, alkali metal hydroxides, carbonates, phosphates and / or silicates.
- the pH is preferably in the range from 8 to 11.
- the thickener b) stabilizes the fiber suspension and delays or prevents the fibers from settling.
- acrylate-based thickeners are suitable.
- xanthan gum is preferably used as the thickener.
- Xanthan gum is a water-soluble polymer based on a polysaccharide.
- the preferred concentration of the thickener is in the range of about 0.1 to about 1% by weight.
- the cleaning agent can additionally contain from about 0.01 to about 5% by weight of nonionic surfactants. It preferably has a surfactant content in the range from 0.5 to 2% by weight.
- the type of nonionic surfactant is not critical. For environmental reasons, preference is given to choosing nonionic surfactants which are biodegradable. Alkoxylates of fatty alcohols are preferred.
- the surfactants can be selected from ethoxylates, propoxylates and ethoxylates / propoxylates of alcohols with a chain length of 9 to 14 carbon atoms in alcohol with at least 2 alkoxylate units. The upper limit of the ethoxylate and / or propoxylate units is about 20.
- the cleaning agent additionally contains about 0.01 to about 1% by weight, in particular about 0.02 to 0.1% by weight, of a preservative.
- a preservative is not critical, but must be based on local legislation. Examples of preservatives are parabens or the so-called "Cathode types" such as methyl chloroisothiazolinone or methyl isothiazolinone are suitable.
- the fibers a) are preferably chemically modified or preferably unmodified vegetable cellulose fibers. These can be in the form of wood, pulp, cotton or paper pulp, for example. Such slurries are referred to as "pulp" in Anglo-Saxon parlance.
- the pulp which may consist of modified vegetable cellulose fibers and water, can represent, for example, ground wood, semi-chemical pulp, sulfite or sulfate pulp, which result from chemical wood pulping, and thermomechanical pulp.
- the use of the fibers of a thermomechanical pulp is particularly preferred since it can be obtained in a simple and economical way. It consists of a wood fiber dispersion and is available by cutting wood into small pieces and digesting them in water at high temperatures.
- the fibers preferably have a length in the range from approximately 1.5 to approximately 3 mm and in particular between approximately 2 and approximately 2.5 mm.
- the proportion of fibers in the cleaning agent is preferably in the range from about 2 to about 10% by weight.
- the invention relates to the use of the cleaning agent described above for cleaning the outer surfaces of vehicles, characterized in that the cleaning agent is diluted with water in a ratio of 1: 1000 to 1: 6, the mixture thus obtained at a pressure between 1 and 100 bar sprayed onto the outer surfaces of vehicles and rinsed with water after an exposure time in the range of 5 seconds to 5 minutes.
- the cleaning agent can be mixed with further cleaning components before or after the dilution with water.
- additional cleaning components are complexing agents, further nonionic, possibly also anionic, zwitterionic or cationic surfactants, additional builder components such as, for example, alkali metal carbonates, borates, phosphates or silicates, carboxylic acids or carboxylic acid anions with chain lengths in the range from 6 to 12 carbon atoms and Alkanolamines.
- the ready-to-use water-diluted preparation of the cleaning agent which may optionally contain the further cleaning components described above, is preferably adjusted to a pH in the range from about 8 to about 11, if necessary using alkali metal hydroxides.
- the use of water-soluble cellulose derivatives according to the teaching of WO 94/19441 is not necessary for the use according to the invention. This component is preferably dispensed with for economic reasons.
- the detergent according to the invention diluted with water, is preferably used in car washes, no mechanical cleaning aids being used.
- the washing systems for vehicles can be washing systems for cars, vans and trucks, buses or rail vehicles.
- mechanical cleaning aids such as rotating brushes or moving textile, plastic or rubber rags, the risk of scratching painted surfaces is significantly reduced.
- the use of the cleaning agent according to the invention thus has the immediate advantage that coated surfaces are protected much more than when using conventional cleaning agents in conjunction with mechanical cleaning aids.
- the cleaning agent can be provided as a one-component system, so that it can be used with little outlay on equipment.
- An additional side effect of using vegetable cellulose fibers is that they can bind heavy metal ions.
- heavy metals are mainly immobilized in the sludge.
- the water phase to be discharged into a biological sewage treatment plant is therefore much less contaminated with heavy metal ions than with cleaning agents that do not use vegetable cellulose fibers.
- a cleaning agent according to the invention can, for example, be composed of:
- thermomechanical pulp 98.35% by weight of thermomechanical pulp with a 4% solids content
- the pH is adjusted to 8 to 9 with KOH.
