Abstract

A means and a process for cleaning pollutants, odorous substances and the like from ambient air are presented and described.

Description

Means and method for purifying the indoor air of pollutants. Odorants and other interfering ingredients

The invention initially relates to a means for purifying the air of pollutants or odorous substances or the like. Annoying constituents.

DE 102 35 043 A1 discloses a device for absorbing pollutants. The known device is used with the use of keratin fibers to bind pollutants in the air, such as formaldehyde, to bind. The keratin fibers, especially sheep wool fibers, are introduced into the polluted rooms, preferably in the vicinity of the pollutant source. The keratin fibers are blended or layered with other materials such as flax, hemp and cotton.

By binding the pollutants to the keratin fibers, the pollution of the indoor air with the corresponding pollutants can be significantly reduced.

On this basis, the invention is based on the object

Means for cleaning the air of pollutants, odors or the. Like. Annoying ingredients provide, which is a good

Has efficacy and which can be used in a less expensive manner.

The invention solves this problem with the features of claim 1.

The principle of the invention initially consists essentially in providing a means which is formed as a liquid. The Liquid can be applied to a room surface. For example, the liquid may be applied to a floor or wall surface of the room or to the surface of a piece of furniture in the room.

The fact that the agent is formed as a liquid and can be applied to a room surface, it is possible, the means without any design effort in the existing space, e.g. into a room of a building or into a vehicle interior, for example by being painted on or otherwise applied to the appropriate room surface as a liquid or foamed as a foam. This can be done with conventional cleaning equipment, for example with a sponge or a cleaning cloth od. Like.

While the agent is on the room surface, even while it is drying, or even after drying for an arbitrarily long period of time, the agents contained in the agent or active ingredient components that absorb in the indoor air disturbing pollutants, odors or other ingredients or bind.

According to the invention, the liquid is applied to the room surface without this room surface having to be changed or influenced in any way. However, the liquid or the active substances or active substance components contained therein can at least partially adhere to the spatial surface and remain there for a longer time even after the liquid has dried. The active compounds can then develop their pollutant-absorbing or absorbing action. Later, the former may be contained in the liquid Active ingredients and active ingredient components, for example in the context of a cleaning process, are removed from the room area again.

While DE 102 35 043 A1 provides a device with a corresponding structure as insulation or sound insulation firmly attached to the corresponding room wall, it is possible with the liquid according to the invention, without any special design effort to achieve a room air purification by the

Liquid is applied as a conventional washing, cleaning or care agent on the corresponding space surface. According to the invention, the liquid can then dry or like a conventional one

Washing, cleaning or care products after a certain

Time interval wiped away and replaced again.

As a liquid in the sense of the present patent application

Fluids or fluids of different viscosity understood. In particular, the agent may be prepared as a low-viscosity liquid, for example having a viscosity comparable to the viscosity of water. Alternatively, the agent may also be in the form of a higher-viscous liquid, for example having a viscosity comparable to that of milk or as a paste or as a gel or as a foam.

According to the viscosity of a conventional washing, care or cleaning agent which exists as a cleansing milk, as a cleansing gel or as a low-viscous cleaning liquid, the means for purifying the room air can be adapted in terms of its viscosity to the care, washing or cleaning agent. Reactive agents or drug components for binding the pollutants may be added as an additive to a conventional care, washing or cleaning agent, without affecting the viscosity of the conventional washing, cleaning or care agent. If, in the context of this present patent application, the term "liquid" is used, it will equally mean always a highly viscous liquid, for example in the manner of a gel, pasty or milk-like fluid.

The liquid may also be prepared as a concentrate and diluted as needed by the user with water or other suitable vehicle. In that regard, the concentrate may preferably be added as an additive to a cleaning agent or a bucket of cleaning water.

Such an additive, which can be labeled as a concentrate, preferably contains an active substance content, in particular a proportion of skieroproteins or corresponding protein complexes, of 10-15 percent by weight or percent by volume. In particular, an approximate 200-fold dilution of the additive with cleaning water, in which a conventional cleaning agent is contained, may preferably be carried out.

The liquid, in particular the concentrate, can have a pH of between 10 and 13.5, preferably between 11, 8 and 12.8. Such a pH value allows an increased reactivity of the active ingredients used, in particular skieroproteins used, with the pollutants in the ambient air.

In the liquid, in particular in the concentrate, the Sklereoproteine can be present alkaline split.

The agent according to the invention is suitable i.a. for building renovation, for the reduction and elimination of

Odor nuisance in rooms and eg to reduce the Pollution in vehicle interiors of brand new vehicles.

According to an advantageous embodiment of the invention, the liquid in the manner of a conventional detergent and / or in the manner of a conventional cleaning agent and / or on the type of a conventional care product on the room surface with a conventional cleaning device, such as a sponge and / or with a cleaning cloth and / or with a cloth and / or with a mop and / or with a scrubbing cloth and / or with a cleaning device, etc. applicable.

The liquid may therefore be used as a conventional detergent or cleaning or care product in a manner known to persons in the household when handling such conventional detergents, care or detergents. The means for purifying the indoor air of pollutants and the like can therefore be used without any special instruction for the user.

The liquid can be spread over the room surface in particular. However, it can also be wiped up and later wiped off or applied with another device.

Preferably, the liquid as such, i. as liquid, can be applied to the room surface. Alternatively, however, it is possible foamed the liquid, od or as a foam or emulsion. Like. Apply to the room surface.

Further preferably, the liquid contains reactive agents or

Active substance components, the pollutants and / or odors and / or Like. Permanently absorb other disturbing components of the room air and / or bind. The active ingredients or active substance components preferably bind the pollutants or odor substances as part of a chemical reaction per se. Such reactions are, for example, in the prior art between formaldehyde and derived from sheep wool keratin fibers, bwz. of mixtures of keratin fibers with other substances known.

The choice of which active ingredients or active substance components are used depends essentially on the type of pollutants or odorous substances or the like present in the room air

Components off. For example, the active ingredients or

Active ingredient components include keratin fibers. Other possible

Active ingredients are, in particular, protein complexes, which include the keratin fibers. For example, skieroproteins are also possible.

Basically come as active ingredients or as active ingredient components in question, which are used in known devices and means for purifying indoor air. It is crucial that the active substances or active ingredient components enter into a chemical reaction with the pollutants to be dissolved out of the room air, in particular with aldehydes, in particular with formaldehyde, or more particularly with VOC (volatile organic compounds), or with odorous substances or with other constituents, and these room air constituents bind and / or neutralize by the chemical reaction. As pollutants of the present patent application, in particular health-endangering or harmful substances are considered.

Special protein bodies or protein complexes, in particular on

Basis of keratin fibers, the od od od substances od. Od. Components of the indoor air can absorb or bind are available, for example, from Air Clean Concept GmbH in Waltenhofen.

With regard to the interaction between, for example, the

Keratin or wool fibers and pollutants present in the ambient air are referred to, for example, the prior art appreciated in the test method of European patent application EP 1 386 622 A1, in particular to the background art additionally used in the second test report.

Possible protein complexes for the active ingredients are amino acids, namely aminocarboxylic acids having the general formula COOH-CHNH 2-R, where the individual amino acids differ with respect to their radical R. The nature of the residue R allows a subdivision of the amino acids into groups. As active substances for the binding of the air pollutants also compounds or mixtures, e.g. of keratin fibers with gelatin substances into consideration. Other combinations of active substances using enzymes, proteins, amino acids, etc. come into consideration.

Even if amino acids are present as macromolecules in a protein composite, they can react chemically. This is possible because amino acids have reactive functional groups in their side chains. The reactive groups of the side chain can be used to absorb and reduce pollutants. For example, sheep protein fiber proteins, which consist of 97% keratins (proteins), have 65% reactive side chain groups that can be exploited for pollutant degradation. According to a further advantageous embodiment of the invention, the liquid contains active substances or active ingredient components which have a cleansing effect and / or a dirt-removing and / or a soil-dissolving action for the room surface. For example, the liquid contains active ingredients as contained in conventional washing, cleaning, cleaning or care products, such as surfactants, enzymes od. Like. The surfactants can, for example, reduce the surface tension and the enzymes can, for example, develop catalytic effects. These conventional active ingredients or active ingredient components may also be contained in the agent according to the invention. In this way, the liquid is on the one hand able to clean the room surface of dirt or dirt. On the other hand, it is also able to absorb and bind the pollutants from the indoor air. Thus, the liquid can be used in the manner of a conventional washing, cleaning, care or cleaning agent and at the same time the desired effect of cleaning the air of pollutants can be achieved without the need for any additional special measures for this additional purpose. The agent may be used as a conventional washing, cleaning or care agent.

According to a further embodiment of the invention, the reactive active substances or active substance components which absorb or bind pollutants, odors or the like. Components of the ambient air and bind those active ingredients or active ingredient components which have a cleansing effect and / or dirt-removing and / or soil-dissolving action for the room area possess, formed of the same materials. Thus, one and the same substance can have both a cleansing or dirt-dissolving or dirt-removing effect and at the same time a room-air-purifying effect. This is possible if the active ingredients are formed, for example, by enzymes, ie by proteins. The enzymes can, for example, proteins (proteases) or fats (Lipases) or starch (amylases) enzymatically degrade. However, since only a certain group of amino acids, which are directly involved in the enzymatic function, are required for the enzyme activity, the large remainder of the amino acids present on the enzyme can be used to take up the pollutants. This can be achieved with a few ingredients of the agent a variety of effects. Enzymes present in a care, cleaning or washing agent can, for example, have a cleaning function both in relation to the room surface and at the same time, based on the room air, develop a pollutant-absorbing effect.

Alternatively, however, it is also possible to use different active substances on the one hand to achieve an optimized cleaning function on the one hand and to achieve an optimized harmful substance absorption function on the other hand.

According to a further advantageous embodiment of the invention, the liquid is a substantially conventional detergent, cleaning agent or care agent containing additional reactive agents or active ingredient components od od the pollutants, odors. Like. Record or bind. Thus, the agent of the invention can be prepared by adding an additive to a conventional washing, cleaning or care agent. In a conventional, for example, also with regard to its formulation known washing, cleaning or care agent, an additive, as an additive, are introduced, which contains the required for the purification of air cleaning agents or active ingredient components. This is also possible after successful tests by the applicant, without the cleaning, dirt removal or Schmutzlösewirkungen the conventional detergent, care or cleaning agent are affected. According to a further advantageous embodiment of the invention, the space surface is a bottom surface, a wall surface or the surface of a piece of furniture. The liquid can therefore be applied to any, preferably on a room surface to be cleaned. For example, the surface of a room is understood as meaning the surface of a plant in the room.

It should be noted that in the context of the present patent application as washing, cleaning and care means understood any means that are used for the cleaning of space surfaces.

For example, it is carpet cleaners, parquet or

Wood surface cleaners, plastic cleaners, furniture polishes,

Detergents, stain removers, all-purpose cleaners, kitchens, household and bathroom cleaners or other cleaning, care or washing agents used in the home and in industrial premises.

The invention further relates to an agent according to claim 13, that solves the task equally. The sprayability according to the invention ensures a particularly uniform distribution of the active substances in the room air or along the room surface.

The invention further relates to a method for the purification of air from pollutants, odors od. Like. Unwanted components of the indoor air.

The object of the invention is to provide a method which is simplified compared to the method described in DE 102 35 043 A1. The invention solves this problem with the features of claim 14.

The inventive method is characterized in that a trained as a liquid agent, which reactive agents or

Contains active ingredient components od the odors or pollutants. The like. Unwanted constituents of the indoor air absorb or bind is applied to a room surface.

The process according to the invention thus essentially provides for the liquid to be applied, brushed, wiped or otherwise applied to the surface of the room.

The inventive method has the advantage that the cleaning of the air of pollutants in the simplest possible way is possible by the fact that the liquid in the manner of a conventional

Plaster, cleaning or detergent is applied to the room surface.

Thus, for example, a liquid may be used in the manner of a conventional floor cleaning agent, this liquid then being sprayed on the floor surface, e.g. on a plank floor, is applied. Since the liquid contains active substances or active substance components which can absorb or bind undesired constituents from the ambient air or the like, it is possible to achieve a very uncomplicated cleaning of the room air.

The inventive method is particularly advantageous if the agent is applied to the room surface in the course of conventional cleaning of the room surface. Preferably, the liquid also contains active ingredients or active ingredient components, which is a for have the room surface cleaning and / or dirt-dissolving and / or dirt-removing effect. In this way, as part of a conventional cleaning of the room surface at the same time also be carried out a cleaning of the room air. This increases the degree of cleaning of the room air.

It is also advantageous if the liquid is repeatedly applied to the room surface after a time interval. For example, a

Cleaning the floor area at regular intervals, eg. B. weekly or monthly. This increases the degree of cleaning of the room air.

If the liquid is applied to the room surface, it can on the one hand clean the room surface and, on the other hand, absorb or bind the pollutants present in the room air. Even after the liquid has dried, the active substances contained in the liquid or contained active substance components can maintain their air purifying effect. If the room surface, in particular the floor area, is cleaned again at a later time, these active substances or active substance components originally contained in the liquid can then be removed or removed from the room surface.

The invention further relates to the use of a detergent and / or a cleaning agent and / or a care agent according to claim 17.

This invention has for its object to simplify the known from DE 102 35 043 A1 process for the purification of indoor air.

This object is achieved by the invention with the features of

Claim 17. The principle of the invention is a detergent, cleaning or care product, in particular a conventional detergent, cleaning or care agent containing reactive agents or drug components that have a cleaning and / or soil-removing and / or soil-removing effect on a room surface, for cleaning of room air of pollutants, odors od. Like. Ingredients to use.

The present patent application describes a new agent, a new process and a new use. With regard to the subject matter described in the patent application, it should be noted that the term absorption means entering into a firm binding of the pollutant or odorant in the air with the agent, in particular with the agent or combination of active ingredients contained in the agent. The pollutant is thus stored in the agent downright and firmly bound to the drug.

Characterized in that the agent is formed as a liquid and the active ingredients or active component contained in the liquid, and the liquid is applied directly to the space surface, in a very thin layer, the active ingredients can interact directly with the room air and react chemically. Even if the liquid is dried and the active ingredients remain adhering to the space surface, the pollutant in the room can constantly react chemically with the active ingredients. Due to the fact that the liquid can be applied to the room surface, the active ingredients are in constant contact with the room air along a very large surface, so that a very high degree of effectiveness is achieved. Characterized in that the agent is formed as a liquid, the corresponding active ingredients can also be repeatedly, in particular regularly applied to the space surface. Thus, the degree of cleaning of the room air is greatly increased.

The combination of a conventional washing, cleaning and cleaning

Care products with active ingredients for cleaning the indoor air of pollutants or odors allows Mit-cleaning of the air in a conventional cleaning process, so without any additional work.
