Description

[0001] The present invention relates to a method for producing a washing and / or disinfecting agent according to the respective preamble of patent claim 1.

[0002] Especially in the Corona pandemic times prevailing at the time of registration, it is necessary to disinfect skin surfaces and / or other surfaces in areas that require high hygiene standards, for example in a nursing home, a hospital or in areas where people are weakened.

[0003] In this respect, the present invention relates to the object of specifying a washing and / or disinfecting agent for washing and / or disinfecting surfaces, in which it is possible in a particularly simple manner to determine whether an effective degree and / or sufficient surface wetting degree prevails.

[0004] This makes it possible to dispense with complex measuring procedures or a specific test procedure, which is based in particular on the experience of the respective user.

[0005] According to at least one embodiment, the washing and / or disinfecting agent for washing and / or disinfecting surfaces, in particular skin surfaces, comprises a base agent which is designed and intended to wash and / or disinfect surfaces, in particular skin surfaces, wherein at least one substance additive is admixed to this base agent which, after contact with the surface, assumes a different color consistency than the base agent for a predeterminable period of time, so that the substance additive serves as a marking agent by means of which the user can read whether the desired areas of the surface to be washed and / or disinfected have been wetted with a sufficient amount of the base agent or have been wetted with the base agent at all and / or whether an exposure time of the base agent has essentially ended.

[0006] In particular, the invention relates to surfaces in - medical sector (inpatient and outpatient,...) - Food sector (production, processing, sales,...) - Cosmetic area - Industry (clean room, production, processing ......) - private area (home environment ....) - social sector (educational institutions, kindergartens, etc.) - public sector (churches, assemblies, offices, communities...) - Workplaces (office and craft .....) - Leisure facilities (sports, swimming pools... anywhere where hygiene rules apply...) - Travel, vacation and other surfaces, especially user interfaces. name Color change pH transition range Cresol red from red to yellow 0,2-1,8 Thymol blue from red to yellow 1,2-2,8 Methyl Yellow from red to yellow 2,4-4,0 Methyl orange from red to yellow 3,1-4,4 Methyl Red from red to yellow 4,4-6,2 litmus from red to blue 5,0-8,0 Bromothymol blue from yellow to blue 6,2-7,6 Cresol red from yellow to violet-red 7,0-8,8 Thymol blue from yellow to blue 8,0-9,8 Phenolphthalein from colorless to red 8,0-9,8 Alizarin Yellow R from yellow to orange-brown 10,1-12,0

[0007] In a Friedel-Crafts acylation, two equivalents of phenol and one equivalent of phthalic anhydride are reacted in the presence of small amounts of concentrated sulfuric acid or zinc chloride:

[0008] Phenolphthalein is a white crystalline powder and practically insoluble in water. It is usually used in a 1% alcoholic solution. It is itself a weak acid.

[0009] Phenolphthalein has a pK s -value of 9.7. If the transition range is set at an indicator acid / base ratio of 1:10 to 10:1, the Henderson-Hasselbalch equation gives a transition range of pH = pK s ± 1 (8.7 to 10.7). At a pH value below 0, an aqueous phenolphthalein solution is reddish-orange, at a pH value of 0 to about 8.2 it is colorless, at higher pH values ​​the solution turns pinkish-violet, and in the strongly alkaline range—at a pH value close to 13—it becomes colorless again. It is therefore well suited as an indicator, for example, for the titration of basic solutions.

[0010] Depending on the pH value of the solution, phenolphthalein changes its structure and thus its color.

[0011] The structures of phenolphthalein species <h2 style=";text-align:left;direction:ltr">H3In<h2 style=";text-align:left;direction:ltr"> + H2In In 2- In(OH) 3- structure pH < 0 0 to 8.2 8.2 to 12.0 > 12,0 Color red colorless pink-violet colorless

[0012] In the pH range up to about 7.5, it exists in its colorless, uncharged basic form (H2In 1). In more basic solutions, the protons at the two hydroxy groups are split off. In a resulting mesomeric limiting structure, a quinoid system is present as a chromophore (In 2- 2). This is the colored structure of the indicator. In a very basic environment, an OH group attaches to the central carbon atom, making it impossible to achieve the chromophore structure (In(OH) 3- 3). In strongly acidic solution, phenolphthalein becomes colored again. The lactone ring is replaced by the H + This creates a positive charge on the central carbon atom, which then becomes 2 -hybridized and is thus again stabilized by the mesomeric limiting form (4).

[0013] For example, if at least one of the above-mentioned dyes is applied to the skin, the pH value of the skin changes, causing the areas moistened with the disinfectant to change from colorless to red or pinkish-violet, depending on the skin condition. The color change takes a certain amount of time, and this time is referred to as the "exposure time" for the purposes of the application. Both the color and the exposure time can be shortened or extended depending on the concentration of the dye in the disinfectant. The more dye there is, the faster the discoloration occurs.

[0014] If we consider the reaction equation of reaction (A) after (B), the law of mass action makes it clear why the color change occurs so quickly: The following applies (K s constant, where the quasi-constant concentration of water in K s is included): The concentration of H3O + -ions is in a different order of magnitude. For acidic solutions it is high, the equilibrium lies on the side of (A). However, as soon as the concentration of H3O + becomes very small or the concentration of OH - becomes large, the concentration of (B) must increase massively due to the constancy of the term. Because (B) is formed from (A), the concentration of (A) becomes much smaller - the color change occurs very quickly.

[0015] Disinfectants alter the protein-containing structure of microorganisms, thereby denaturing them. Depending on the type of disinfectant, they can also damage the lipid membranes and nucleic acids of the germs.

[0016] All disinfectants can be described as substances that have a microbicidal effect due to their chemical properties. This means they inactivate or kill microorganisms that cause disease and / or infection.

[0017] In contrast to sterilization, not all microbiological organisms are eliminated, but rather a specific type of germs is reduced. The idea is to eliminate several bacterial strains that are vital to humans or are non-pathogenic (i.e., non-disease-causing). The risk of infection from microorganisms is tied to a specific population density. Only when a lower limit of pathogens is reached does it become dangerous for humans.

[0018] Disinfectants should meet the following requirements: • They are designed to reduce the number of germs quickly and comprehensively. • Disinfectants must achieve a sufficient penetration depth. • The product must be resistant to organic material. • Disinfectants should have only a low systemic toxic effect (not on the entire organism), • Compatibility with skin, mucous membranes and open wounds must be ensured. • The disinfectant must be long-lasting and at the same time biodegradable. • Ultimately, odor pollution in the medical field should be kept to a minimum.

[0019] Disinfectants specifically kill the microorganisms they are used to treat. They must not contain active ingredients that damage or alter the surrounding organic material. If a disinfectant is administered into a wound during surgery, it must not affect either intact or open skin or the underlying tissue.

[0020] Disinfectants have a denaturing effect, meaning they alter the protein-containing structures of microorganisms and thus destroy them. Some disinfectants also damage the lipid membranes (e.g., the envelope of viruses) or the nucleic acids of the germs. In addition to the specific active ingredient, disinfectants contain so-called

[0021] Excipients that ensure the active ingredient can reach the site of action. Based on their mode of action, disinfectants can be divided into the following categories: • Protein denaturation • Oxidation • Reduction of surface tension • Enzyme inhibition • Change in nucleic acids

[0022] Each disinfectant effect is triggered by specific ingredients, although several combinations may be used. Protein denaturation, for example, is achieved by disinfectants containing aldehydes or alcohols—regardless of whether the medium is alkaline or acidic. If microorganisms are to be oxidized, hydrogen peroxide, among other substances, splits off the electrons from the germs.

[0023] The susceptibility of pathogens is achieved by reducing their surface tension, for which, for example, phenols are added to the disinfectant. During the syphilis era, disinfectants containing heavy metal compounds were increasingly used to inhibit the pathogens' enzymes. The last major group of disinfectants contains peracids (peroxycarboxylic acids) and thus alters the structure of nucleic acids, essentially acting like an oxidizing agent.

[0024] The precise definition of the individual active ingredients and excipients is a biochemical science in itself. This overview is intended merely to provide the basics for understanding the differentiation of disinfectants. The following substances are to be understood as base agents for the purposes of this application. Each of the base agents can be mixed with at least one of the base substances presented above. "Mixing," for the purposes of this application, means the mixing of two or more substances to achieve the most even distribution of the individual components throughout the mixture. Mixing is used in the production of batches and mixtures, suspensions, emulsions, and solutions. Phenols

[0025] Phenols are only effective against bacteria, fungi, and myoorganisms in high concentrations. Phenols are primarily used for surface disinfection. Alcohols

[0026] Alcohols have multitoxic uses. They denature proteins from bacteria, viruses, and fungi. However, this fast-acting disinfectant must be diluted with water, or the item to be disinfected must be kept wet throughout the entire exposure time. Usually, 3 to 5 ml of alcoholic solution is sufficient for adequate disinfection. Aldehydes

[0027] Aldehydes, such as formaldehyde, would be an ideal disinfectant because they also work in a gaseous state. This allows both large surfaces and delicate devices to be vaporized. However, the separation of carbon and hydrogen atoms (change in nucleic acids) is highly dependent on external influences. Furthermore, the long exposure time of six hours and the pungent odor of the gas are objectionable. Surfactants

[0028] Surfactants reduce surface tension. In detergents, they ensure that water and oils bond together; in disinfectants, they are classic adjuvants for transporting the active ingredients into the pathogens being combated. Cation-active substances

[0029] Cationic substances inhibit growth in low concentrations. In higher concentrations or with longer exposure times, they kill microorganisms. Cationic substances are characterized by a positive, water-soluble group, which enables them to split off electrons from microorganisms—a process known as oxidation. Amphoteric substances

[0030] Amphoteric substances contain both positively and negatively charged particles. Their effect is therefore equally effective at all pH values. Due to their good skin compatibility, they are particularly used for hygienic hand disinfection. Halogens

[0031] Halogens such as chlorine, iodine, and fluorine occupy the penultimate shell of the periodic table and are therefore extremely eager to climb to the last shell, the noble gas configuration, by gaining electrons. These disinfectants are toxic not only to bacteria in high concentrations and should therefore be used with caution. • Chlorine and chlorine compounds, in particular, oxidize SH groups in proteins. Chlorine, for example, is used in drinking water disinfection, producing so-called hypochlorites. These also have a microtoxic effect and are used for general disinfection. • Iodine is poorly soluble in water and is therefore used in combination with potassium iodide to form potassium tincture. Since iodine can cause allergic reactions as a disinfectant in some cases, it is now primarily used to treat medical devices and instruments. Metals and metal salts

[0032] Metals and metal salts such as cadmium, silver, copper, and mercury have a microbicidal effect known as oligodynamics. The released metal ions block the proteins of microorganisms, thereby killing them. A typical application is covering open wounds with silver foil. Oxidants, also called oxidizing agents, transfer oxygen to other substances, such as bacteria, viruses, and the like, which are thereby altered. Their effect as disinfectants is comparable to that of halogens: • In aqueous solution and at high humidity, ozone is effective against all bacteria, viruses, fungi, and even spores. In dry air, however, it has no effect on reducing germs. • Peroxides are used in medicine as a 30 percent solution. Because they decompose without prior action by peroxidases (which are present in large numbers in the skin), they are largely replaced by alcohol-based disinfectants. • Peracids are corrosive in high concentrations and are therefore unsuitable for near-patient disinfection. They are primarily used for room and surface disinfection. • While acids and alkalis destroy microorganisms, they usually also damage the material being disinfected. Strong hydrochloric acids or caustic soda solutions are therefore not used as disinfectants. However, with special preparations, organic acids such as lactic acid can be used to disinfect dialysis machines and oral irrigators, or as a supplement to other disinfectants.

[0033] In addition to the ingredients and modes of action, various methods for grouping disinfectants have become established. One can use the disinfectant's area of ​​application as a grouping criterion, and the other can use the microorganism it is intended to combat. Classification of disinfectants according to area of ​​application

[0034] The list of possible uses for disinfectants is long. In everyday clinical practice, four main areas are distinguished: Skin disinfectant

[0035] Skin disinfection should treat both permanently present germs and those that are likely to be touched. Resident and transient germs do not pose a problem on intact skin. However, if they enter the patient's body during invasive procedures, they can spread virtually unhindered without prior treatment with disinfectants for skin and wounds. The contact time of the disinfectant depends on both the active ingredient used and the condition of the skin. Disinfectants intended for direct skin contact usually contain alcohols such as ethanol or propanol. Surface disinfectants

[0036] Surface disinfection is an integral part of the disinfection plan and is carried out both routinely and in the event of special incidents. For example, the floors in patient rooms are routinely disinfected after the patient is discharged. If the same floor comes into contact with organic material (feces, blood, vomit, etc.), unscheduled surface disinfection is performed. Disinfectants containing aldehydes, chloramines, cationic substances, or peroxides, such as our product Desonova, are particularly suitable for this purpose. Instrument disinfectant

[0037] When disinfecting instruments, it is important that the disinfectant reaches even the smallest recesses and holes. It should therefore be highly water-soluble and dry quickly, or have a short contact time. Disinfectants with cationic substances or various halogens are typically used for this purpose. Drinking water disinfectant

[0038] Drinking water disinfection is understandably a significant factor in hospitals and nursing homes. After disinfection, neither pathogenic germs nor any residues caused by the disinfectant may remain in the drinking water. In Germany, oxidative agents such as calcium hypochlorite and sodium chloride, chlorine dioxide, chlorine, and ozone are permitted.

[0039] The names of disinfectants when categorized according to target organisms also provide information about the microorganisms they are intended to target. In the hygiene sector, the different disinfectants are divided into the following categories: • A very common bactericide is the antibiotic. The use of a bactericide damages bacteria to such an extent that cell death is triggered. • A virucide is a disinfectant that kills viruses. It irreversibly damages the nucleic acids of viruses, thereby deactivating or completely killing the microorganism. • Fungicide means "kills fungus." In medicinal treatment, they are also referred to as antimycotics (mycosis is a fungal infection). Fungicidal disinfectants sometimes only work against existing fungal cultures (e.g., alcohols), but are powerless against the spores deposited there. • This deficiency is compensated for by a sporicide. Chlorine dioxide, for example, is a fast-acting sporicide and is used to treat surfaces, instruments, and drinking water. To remove spores from the skin or mucous membranes, hydrogen peroxide is used instead, which is more easily tolerated. • Leuvurozide is a fungicide that can also be used successfully against yeast fungi. • Virostatic and fungistatic disinfectants: inhibit the proliferation of viruses or bacteria, but do not kill them.

[0040] Most disinfectants are multitoxic, meaning they can be used against multiple types of pathogens. Peracetic acid, sodium hypochlorite, formaldehyde, and ethylene oxidine, for example, achieve effective results as bactericides, sporicides, fungicides, and virucides. Which disinfectant is selected, given equal effectiveness, depends on the application area in which the active ingredient is to be introduced.

[0041] In particular, within the scope of the invention, the application of artificial intelligence can be used, for example by means of a computer, to recognize the area of ​​a field on the surface detected with the disinfectant and, for example after prior limit setting, or completely generically (i.e. AI-based), to decide where enough disinfectant or even disinfectant at all has come into contact with the surface, in particular the skin. The AI ​​can also be trained to determine whether a period of time since wetting is sufficient, particularly by evaluating the color change. It is conceivable that the computer then decides through self-learning whether the amount is sufficient and whether sufficient time has been waited to achieve a minimum and thus sufficient disinfectant effect. The AI ​​can then be trained by the user, who repeatedly teaches the AI ​​when (amount and time elapsed) disinfection has been sufficient.For this purpose, a scanner can first fully automatically detect the area wetted with the disinfectant. The AI ​​can then divide this area into individual sectors, and for each sector, the AI ​​learns to decide whether sufficient sector disinfection has been achieved. Only when a certain minimum number or all sectors receive the "green light" from the AI ​​does the AI ​​notify the user that they have disinfected sufficiently. After a certain training phase, the AI ​​can organize such a disinfection lock process itself, ideally entirely without human intervention.

[0042] Artificial intelligence (AI), also known as artificial intelligence (AI), is a branch of computer science that deals with the automation of intelligent behavior and machine learning. The term is difficult to define because there is no precise definition of "intelligence." Nevertheless, it is used in research and development.

[0043] Artificial intelligence usually refers to the attempt to replicate certain human decision-making processes, for example, by building and programming a computer so that it can solve problems relatively independently. However, it is often also referred to as imitated intelligence, where "intelligent behavior" is intended to be simulated using mostly simple algorithms, such as those used by computer opponents in computer games.

[0044] Strong AI would be computer systems that can perform complex tasks on a par with humans. In contrast, weak AI is about solving specific application problems. It aims to support human reasoning and technical applications in specific areas. The ability to learn is a key requirement for AI systems and must be an integral component, not an afterthought. A second key criterion is an AI system's ability to deal with uncertainty and probabilistic information. Of particular interest are applications that are generally considered to require some form of "intelligence" to solve them. Ultimately, weak AI is about simulating intelligent behavior using mathematics and computer science; it is not about creating consciousness or achieving a deeper understanding of intelligence.While the creation of strong AI has so far failed due to its philosophical questions, significant progress has been made on the side of weak AI in recent years.

[0045] A strong AI system doesn't necessarily have to share many similarities with humans. It will likely have a different cognitive architecture and its developmental stages won't be comparable to the evolutionary cognitive stages of human thought (evolution of thought). Above all, it can't be assumed that an artificial intelligence possesses emotions such as love, hate, fear, or joy.

[0046] Visual intelligence enables the recognition and analysis of images and shapes. Examples of applications include handwriting recognition, human identification through facial recognition, fingerprint or iris matching, industrial quality control, and manufacturing automation (the latter in combination with robotics).

[0047] In the present case, therefore, at least one embodiment involves such a device and / or a method which exploits precisely these AI features, so that instead of an inaccurate subjective assessment (has one waited long enough for a sufficient color change), the self-learning AI automatically detects whether a sufficient area of ​​the surface (1) has been wetted and whether a sufficient color change has been achieved as a sign of a sufficient waiting time until sufficient disinfection.

[0048] According to at least one embodiment, the substance additive is mixed with the base agent at a concentration of at least 3 vol% and / or at least 3 mol%, in particular a predetermined weight and / or volume amount of the base agent. It has been recognized that this concentration range is particularly well suited to achieving the most complete disinfection possible, and the time range for the discoloration is also selected such that the user does not have to wait too long for the result and thus for sufficient discoloration.

[0049] According to at least one embodiment, the substance additive comprises at least one dye which reflects and / or generates light in the visible wavelength spectrum.

[0050] According to at least one embodiment, the additive is added to the base agent in gel-like and / or viscous and / or liquid form. Gels can be described as viscoelastic fluids. The fluid properties of a gel thus lie between those of an ideal liquid and those of an ideal solid. The storage modulus and the loss modulus are often used as parameters to classify the gel-like nature of a viscoelastic fluid in rheology. As a rule, a fluid is considered to have gel character if the storage modulus is greater than the loss modulus.

[0051] Gels are semi-solid, more or less transparent products. They consist of a three-dimensional network of scaffolding agents (e.g., gelatin, cellulose derivatives, and polyacrylates), whose interstices can absorb large amounts of moisture and conditioning agents. Three different types of gels are distinguished: anhydrous oleogels, oil-free hydrogels, and oil / water gels.

[0052] Gels are characterized by their intensive moisturizing properties and rapid absorption. They spread particularly quickly on the skin and are absorbed immediately without stickiness. Special additives, such as menthol, often provide a cooling, refreshing effect. These application properties have led to the increasing popularity of gels, especially among people with sensitive skin.

[0053] If an emulsion is additionally integrated into the network of a gel, a gel-cream is created that combines the moisturizing properties of a gel with the care effects of an emulsion.

[0054] According to at least one embodiment, the additive comprises at least one time marker which, after application to the surface, in particular to the skin surface, glows on the surface based on the dye for a predetermined period of time, and after this period has elapsed, at least partially stops glowing, which indicates to the user that an exposure time of the base agent has elapsed.

[0055] According to at least one embodiment, the present invention relates to a use of a washing and / or disinfectant.

[0056] According to at least one embodiment, the method for producing a washing and / or disinfecting agent for washing and / or disinfecting surfaces comprises a base agent which is designed and intended to be used to wash and / or disinfect surfaces, in particular skin surfaces, and the provision of a substance additive which, after contact with the surface, assumes a different color consistency than the base agent for a predeterminable period of time, so that the substance additive serves as a marking agent by which the user can read whether the desired areas of the surface to be washed and / or disinfected have been wetted with a sufficient amount or even with the base agent and / or whether the contact time of the base agent has essentially been completed, wherein this additive is added to the base agent, wherein the detection is fully automatic by means of a self-learning AI,whether a sufficient area or surface has been wetted and whether a sufficient color change has been achieved as a sign of sufficient waiting time until adequate disinfection has been achieved.

[0057] The additive can be a luminescent and / or fluorescent agent, or at least contain one. This can be within the light spectrum visible to the human eye. In this context, "gel-like" means that the base agent has a consistency with the essential characteristics of a gel. For example, the additive can actually be a gel.

[0058] The same applies to the terms viscous and liquid.

[0059] A viscous substance can be one that has a viscosity which indicates that the higher the viscosity, the thicker (less flowable) a fluid is and the lower the viscosity, the thinner (more flowable) it is.

[0060] For example, the additive is a viscous or gel-like substance.

[0061] It is conceivable that the base forms a suspension together with the additive.

[0062] It is also conceivable that the additive forms an emulsion with the base substance or that the additive is dissolved in the base substance so that a solution develops.

[0063] The time marker described here can be a chemical element either in the additive and / or in the base substance, which changes upon contact with ambient oxygen and / or upon contact with a skin surface in such a way that a corresponding chemical and / or physical process is initiated within the time marker, which takes place over a predetermined period of time. It is conceivable that the user perceives a glow or other color coding for a period of 30 seconds or 40 seconds, or another period of time that can be set arbitrarily based on the substance mixture and the time marker, after distributing the detergent and / or disinfectant on the skin surface. This color coding disappears after a predetermined period of time, which is preferably dimensioned such that it indicates that a sufficient disinfection exposure time has been exceeded.In other words, if only the glow has essentially disappeared, sufficient disinfection has been achieved with regard to reducing bacteria and / or viruses or completely killing them.

[0064] In the following, the invention described here is presented in more detail with reference to a figure and the associated description.

[0065] In the Fig. 1 shows a plan view of a surface 1, in particular a skin surface 1, that the washing and / or disinfectant 100 is used for washing and / or disinfecting surfaces 1, in particular skin surfaces 1.

[0066] What can be seen is a base agent which is designed and intended for the purpose of washing and / or disinfecting surfaces 1, in particular skin surfaces 1, with said base agent having at least one substance additive 3 added thereto which, after contact with the surface 1, assumes a different color consistency than the base agent 2 for a predeterminable period of time, so that the substance additive 3 serves as a marking agent by means of which the user can read whether the desired areas of the surface 1 to be washed and / or disinfected have been wetted with a sufficient amount or at all with the base agent and / or whether the contact time of the base agent has essentially been completed.

[0067] The substance additive 3 is admixed with at least 3 vol-% and / or at least 3 mol-% to the base agent and in particular to a predetermined weight and / or volume amount of the base agent and comprises at least one dye which reflects and / or generates light in the visible wavelength spectrum.

[0068] It can be seen that the substance additive 3 is added to the base agent in gel and / or liquid form.

[0069] This additive 3 comprises at least one time marker which, after application to the surface 1, in particular to the skin surface 1, glows on the surface 1 for a predetermined period of time based on the dye, and after this period has elapsed, at least partially stops glowing, which indicates to the user that an exposure time of the base agent has elapsed.

[0070] The Fig.1 thus shows a washing and / or disinfecting agent for washing and / or disinfecting surfaces 1 as well as a use of a washing and / or disinfecting agent 200 and a method for producing a washing and / or disinfecting agent 300 for washing and / or disinfecting surfaces 1, which comprises a blowing agent which is designed and intended to be used to wash and / or disinfect surfaces 1, in particular skin surfaces 1.

[0071] In particular, within the scope of the invention, the application of artificial intelligence can be used, for example by means of a computer, to recognize the area of ​​a field on the surface detected with the disinfectant and, for example after prior limit setting, or completely generically (i.e. AI-based), to decide where enough disinfectant or even disinfectant at all has come into contact with the surface, in particular the skin. The AI ​​can also be trained to determine whether a period of time since wetting is sufficient, particularly by evaluating the color change. It is conceivable that the computer then decides through self-learning whether the amount is sufficient and whether sufficient time has been waited to achieve a minimum and thus sufficient disinfectant effect. The AI ​​can then be trained by the user, who repeatedly teaches the AI ​​when (amount and time elapsed) disinfection has been sufficient.For this purpose, a scanner can first fully automatically detect the area wetted with the disinfectant. The AI ​​can then divide this area into individual sectors, and for each sector, the AI ​​learns to decide whether sufficient sector disinfection has been achieved. Only when a certain minimum number or all sectors receive the "green light" from the AI ​​does the AI ​​notify the user that they have disinfected sufficiently. After a certain training phase, the AI ​​can organize such a disinfection lock process itself, ideally entirely without human intervention.

[0078] In addition, the method 300 comprises providing a substance additive 3 which is admixed with the base agent, which after contact with the surface 1 takes on a different color consistency than the base agent 2 for a predeterminable period of time, so that the substance additive 3 serves as a marking means by which the user can read whether the desired areas of the surface 1 to be washed and / or disinfected have been wetted with a sufficient amount or at all with the base agent and / or whether an exposure time of the base agent has essentially been completed.
