Description

[Detailed description of the invention]

The present invention is applicable to plastics, ceramics, tiles, joints,
The present invention relates to a two-component foaming hard surface cleaning composition that can effectively remove dirt from hard surfaces such as the inside of drain pipes. Traditionally, household detergents for plastics, ceramics, and tiles have been known as liquid detergents containing acids or alkalis as their main ingredients, and as detergents for joints, powdered or liquid detergents containing abrasives have been used. Are known. However, all of these detergents still had insufficient cleaning power. In recent years, with the emergence of Western-style general housing or high-rise apartment complexes and the Westernization of eating habits, food waste, excrement, hair, Dirt, bathroom grime, and other dirt clogs or adheres to the inner walls of pipes, which often obstructs the flow of water within the pipes. Such stains inside drain pipes are one of the most difficult to remove among hard surface stains in the home, partly because the dirty parts are difficult to reach. Conventionally, the method for removing dirt from drain pipes, traps, pipes, etc. is to dissolve and emulsify it using chlorinated hydrocarbons and an activator (U.S. Patent No.
3553145 specification), a method of decomposing dirt with enzymes and microorganisms (Japanese Patent Publication No. 38-26465), a method using soda percarbonate and an activator (Japanese Patent Application Laid-open No. 152406/1982), a method using an acid agent and an alkaline carbonate. Method (Unexamined Japanese Patent Publication 1973-
50207), a method using an oxidizing agent such as an acid agent, an alkaline carbonate, and sodium percarbonate (Japanese Unexamined Patent Publication No. 53
-50208 Publication), but none of these have sufficient cleaning power. US Pat. No. 3,471,407 reports a method of adding strong alkalis such as caustic soda, aluminum, and inorganic nitrates, but this is extremely dangerous. Also, U.S. Patent Specification No.
3538008 specifies H ₂ SO ₄ , HCl, HNO ₃ ,
A method of adding a strong acid such as orthophosphoric acid or sulfamic acid and silica sol has been disclosed, but this method is also extremely dangerous and highly corrosive. On the other hand, it is also known to use aerosol injection pressure to open a completely clogged drain pipe, but this method has little effect on dirt deposited on the walls. It is possible to physically clean the inside of the drain pipe, but this is time-consuming and difficult to do easily at home. The present invention was made to solve the problems of the prior art as described above, and can easily and effectively remove stains from hard surfaces such as plastics, ceramics, tiles, joints, bathtubs, and inside drain pipes. It is an object of the present invention to provide a two-part foaming hard surface cleaning composition that can be used to clean surfaces. That is, the two-part foaming hard surface cleaning composition of the present invention is characterized by having the following parts A and B. The two are brought into contact or mixed during use, and water is added if necessary. (1) Agent A: Contains inorganic peroxide and has an effective oxygen amount of 0.25
~25% oxygen-based oxide composition or an aqueous solution of this composition. (2) Agent B: Contains hypochlorite and has an effective oxygen amount of 0.25
~60% chlorine-based oxide composition or an aqueous solution of this composition. The present invention will be explained in more detail below. Part A is an oxygen-based oxide composition containing an inorganic peroxide or an aqueous solution thereof, and the amount of inorganic peroxide in Part A is 0.5 to 50% by weight in the case of a liquid, and 10 to 100% by weight in the case of a solid. %, more preferably 1 to 3 wt% and 30 to 90 wt%, respectively.
It is. And the amount of effective oxygen in agent A is 0.25 to 25
%, preferably 0.5 to 20%. If the amount of effective oxygen is less than 0.25%, sufficient cleaning power cannot be obtained, while if it exceeds 25%, storage stability deteriorates and it is also dangerous to handle at home, which is not desirable. Here, the effective oxygen amount is the ratio (% by weight) of the amount of oxygen (O) contained in the A agent that is effective for bleaching etc. to the entire A agent. This can be measured by a conventional method using potassium permanganate or the like. Any inorganic peroxide that can be used as agent A can be used as long as it reacts with hypochlorite and decomposes, but hydrogen peroxide and sodium percarbonate (Na ₂ CO ₃ .nH ₂ O ₂ , typically n=
3/2) is a hydrogen peroxide adduct. Other specific examples include sodium perborate,
These are hydrogen peroxide adducts of sodium sulfate, hydrogen peroxide adducts of sodium silicate, and hydrogen peroxide adducts of sodium orthophosphate. Among the above, particularly preferred are hydrogen peroxide and sodium percarbonate. Agent B is a chlorine-based oxide composition containing hypochlorite or its aqueous solution, and the amount of hypochlorite in Agent B is 0.25 to 40% by weight in the case of a liquid, and 0.25 to 40% by weight in the case of a powder. It is preferably 1 to 100 wt%, more preferably 1 to 15 wt% and 10 to 100 wt%, respectively.
It is 90wt%. And the amount of available chlorine in agent B is
It is 0.25 to 60%, preferably 1 to 15%.
If the amount of available chlorine is less than 0.25%, sufficient cleaning power cannot be obtained, while if it exceeds 25%, storage stability will be significantly deteriorated and it is also dangerous to handle at home, which is not desirable. Here, the effective chlorine amount is the ratio of the amount of chlorine (Cl ₂ ) contained in the B agent that is effective for bleaching, etc. to the entire B agent. Examples of the hypochlorite of agent B include sodium hypochlorite, potassium hypochlorite, and highly refined white powder, with hypochlorite being particularly preferred. The properties of the A agent and the B agent may be liquid (solution), solid or normal (powder-like). Particularly preferable combinations of agent A and agent B are as follows. (1) Liquid/liquid type Part A: 1.0-35wt% hydrogen peroxide solution Part B: 1.0-15wt% sodium hypochlorite aqueous solution (2) Powder/liquid type Part A: 10 to 10% of sodium percarbonate Powder composition containing 100wt% Part B: 0.5-15wt% sodium hypochlorite aqueous solution (3) Liquid/powder type Part A: 1.0-35wt% hydrogen peroxide solution Part B: 2.0-100wt% bleaching powder Powder composition containing (4) Powder/powder type Part A: Powder composition containing 10 to 100 wt% of soda percarbonate Part B: Powder composition containing 2.0 to 100 wt% of bleaching powder Foaming cleaning of the present invention In the agent composition, a surfactant may be further added to either or both of the A agent and the B agent. The surfactant mainly contributes to the stability of foaming, as will be explained in detail later. Therefore, any material having such an effect can be used, and it is preferable to use a material that can be stably stored with the A component or the B component. As surfactants, anionic surfactants,
Any of nonionic surfactants, cationic surfactants, and amphoteric surfactants can be used, but anionic surfactants and nonionic surfactants are particularly preferred. Specific examples of such surfactants include the following. (1) Anionic surfactants Fatty acid salts with 10 to 20 carbon atoms Alkyl sulfates with 10 to 18 carbon atoms Alkylbenzene sulfonates with 10 to 18 carbon atoms α-olefin sulfonates with 8 to 18 carbon atoms Ethylene oxide with 8 to 18 carbon atoms Polyoxyethylene alkyl ether sulfonate with an average added mole number of (EO) EO of 1 to 10 moles Polyoxyethylene alkyl phenyl ether sulfonate with 6 to 12 carbon atoms and EO = 6 to 20 (2) Nonionic surfactant Carbon Several 10 to 20 alcohol EO adducts (EO
= 6 to 20) Alkylphenol EO adduct with alkyl group having 6 to 12 carbon atoms (EO = 6 to 20) Sorbitan alkyl ether EO adduct with alkyl group having 12 to 18 carbon atoms (EO = 3 to 30) Fatty acid EO adducts with 12 to 18 carbon atoms (EO=5
~50) (3) Cationic surfactant Quaternary ammonium salt Imidazolinium quaternary salt (4) Ampholytic surfactant Betaine Amino salt Imidazoline Among the above surfactants, it is particularly superior in terms of foaming properties. These include alkyl sulfates with an average number of carbon atoms of 12, alkylbenzene sulfonates with an average number of carbon atoms in the alkyl group of 12, α-olefin sulfonates with 12 to 18 carbon atoms, and polyoxyethylene nonyl phenyl ether (EO = 8 to 10). Anionic surfactants such as lauryl alcohol EO adducts (EO=8-10), nonyl phenyl ether
Examples include nonionic surfactants such as EO adducts (EO=8 to 10). In addition, in terms of stability during storage, alkyl sulfates with an average carbon number of 12,
Polyoxyethylene nonylphenyl ether (EO = 8 to 10), lauryl alcohol EO adduct (EO = 8 to 10), nonylphenyl ether EO adduct (EO = 8 to 10), etc. are superior. In addition, alkyl sulfates with an average number of carbon atoms of 12, alkylbenzene sulfonates with an average number of carbon atoms in the alkyl group of 12, and α-
Examples include anionic surfactants such as olefin sulfonate and polyoxyethylene nonyl phenyl ether (EO=8 to 10). Surfactant is 0.1 to 20% by weight in Part A or Part B.
It is preferable that the amount is added such that it is included, and more preferably 0.5 to 10% by weight. This amount is 0.1
If it is less than 20%, sufficient foaming power or foam stability cannot be obtained, and if it exceeds 20%, the stability during storage will be significantly deteriorated and the cleaning effect will be reduced due to the reduction in the amount of active ingredients. Next, a method for using the hard surface cleaning composition of the present invention and a cleaning mechanism will be explained. Parts A and B are stored separately and each is applied separately onto the hard surface soil at the time of use. The order of application may be either first or simultaneously. For liquid/powder and powder/liquid types, it is more practical to spread the powder first and then pour the liquid. Also, for the powder/powder type, add an appropriate amount of water after spraying both. The liquid/liquid type is also easy to handle and convenient for applying the desired amount to any hard surface, especially hard surfaces such as hard to reach places or vertical surfaces.
From this point of view, hydrogen peroxide and sodium hypochlorite, which can be stably stored even in liquid form, are advantageous. When Agent A and Agent B come into contact with each other on hard surface dirt and react, the dirt is decomposed by the oxidizing power of the generated oxygen. Oxygen is generated by both the decomposition of inorganic peroxide and the decomposition of hypochlorite, and acts synergistically on dirt to decompose it. In particular, since hypochlorite has a strong disinfecting power, it also acts as a disinfectant, especially as a mold remover. In addition, a large amount of air bubbles generated by the reaction is used to remove dirt by physical force. Therefore, it can be effectively removed even in hard-to-reach places, and even on the outer surface, it can be removed without scrubbing or the like. Furthermore, due to the generation of air bubbles, the cleaning agent can be spread even to places where the cleaning agent is difficult to reach, such as recesses, due to the filling power of the air bubbles, making it possible to perform cleaning efficiently. Foaming also makes it easier for the cleaning agent to adhere to hard surfaces, allowing it to remain on inclined and vertical surfaces for a sufficient period of time necessary for cleaning. Furthermore, the adhesion of dirt can be reduced by the heat of reaction between Agent A and Agent B. As described above, in the cleaning composition of the present invention, peroxide and hypochlorite are decomposed. (1) Oxidizing power and sterilizing power (2) Physical external force on dirt due to foaming, filling of cleaning agent, and adhesion or stagnation of cleaning agent (3) Reaction heat works synergistically to prevent conventional cleaning. It provides excellent cleaning power that could not be imagined with detergents. It is very common for the hard surfaces to be cleaned to have slopes or surfaces that are difficult to clean, such as recesses or corners. Therefore, foaming power or foam stability is an important factor. For example, consider the drain pipe of a household sink. These drain pipes descend almost straight down, and many have bellows structures on their side walls. A predetermined flow channel is formed within the pipe, and when water is allowed to flow, the water does not flow uniformly within the pipe, but flows along the flow channel. Even if a cleaning agent is poured into such a drain pipe, the cleaning agent only comes into contact with specific areas, and
It washes off quickly and cannot be cleaned efficiently. Powdered foaming compositions have also been reported in JP-A-52-152406, JP-A-53-50207, and JP-A-53-50208, which have already been mentioned, but these have poor foaming amount and foaming power. It is sufficient and when applied to the above-mentioned drain pipe, it quickly flows down while foaming. On the other hand, when Agents A and B of the present invention are used, both the amount of foaming and the foaming power are strong, and the entire inside of the drain pipe is filled and a physical force is applied to the dirt. Moreover, it slowly descends inside the drain pipe and comes into contact with the dirt for a sufficient period of time. In particular, when at least one of the A agent and the B agent contains a surfactant, the foaming power increases and the generated bubbles become stable, further enhancing the foaming effect described above. As is clear from the above explanation, the second aspect of the present invention
The foaming detergent composition is effective on all hard surfaces, such as moldy surfaces, inclined surfaces, vertical surfaces, and other areas where the cleaning agent easily flows, as well as recesses, corners, and inside pipes. It is particularly effective for areas that need to be cleaned. Specifically, it is particularly effective as a toilet cleaner, mold remover, ventilation fan stain remover, and drain pipe cleaner. The cleaning composition of the present invention further contains mirabilite, soda carbonate, salt,
Bulking agents such as sodium triphosphate, sodium diphosphate, tripolyphosphate, pylocaliphosphate,
Colorants, fragrances, fungicides, chelating agents, activators,
Alkaline agents or other additives commonly added to cleaning agents can be added. It is preferable that these additives are added so as not to impair the stability or function of the A agent and the B agent. For example, it is preferable that a chelating agent or an activator be added to the A agent. Example 1 Each sample shown in Table 1 was prepared and evaluated for its ability to remove urine scale.
