Description

  The present invention relates to a drainage outlet or pipe foam having an aerosol spray mechanism and a drainage outlet or pipe viscous cleaning agent that can be used to wash the drainage outlet or pipe and efficiently remove dirt, malodor, slime, and the like. It relates to cleaning agents.

  Cleaning of physical dirt, microbial dirt, bad smell, slime, etc. in drains or pipes such as kitchens, washrooms, toilets, bathrooms and bathtubs is maintenance of daily life that is indispensable in modern life. Especially in apartment houses and other apartments, the piping from the drain outlet to the sewer is long and has a complicated structure, so cleaning is not easy. In some cases, extensive cleaning may be required. Therefore, it is important to periodically clean the drain outlet or pipe cleaning agent, and granule / powder type or liquid type drain outlets or pipe cleaning agents are widespread. The main component of cleaning is a surfactant, but if it is only a surfactant, it will reach all of the complicated structure in the drain outlet or pipe, and it is difficult to efficiently exert the cleaning effect. Therefore, it is generally practiced that a foam is formed by the surfactant itself or a further added agent at the time of use so that the surfactant and the soil come into sufficient contact to obtain a continuous and efficient cleaning effect. In addition, regarding the cleaning agent, many proposals for improving the cleaning effect have been made. For example, there is a proposal (Patent Document 1) for improving the cleaning effect by using one or more anionic surfactants and a betaine double-sided surfactant in combination to form a gel-like composition for a long time. Since two or more kinds of active agents are used to obtain a gel-like product, there is a disadvantage that the configuration is complicated and the cost is increased. In addition, there is a proposal (Patent Document 2) that contains a polyoxyethylene surfactant and an alkali agent, gives a viscosity of 2 to 1000 centipoise, and is liquid immediately after the aerosol, but the viscosity is high. On the contrary, it becomes difficult to reach all of the inside of the pipe, resulting in insufficient cleaning. In addition, as a proposal to improve this, a proposal is made to use a water-soluble polymer or a thickener together with a surfactant to adhere to a vertical wall surface or the inside of a pipe for cleaning (Patent Documents 3 to 5). Although the foam stability is increased, the liquid does not reach the inside of the complicated pipe, and the foam does not foam up to the opening of the drain.Therefore, an insufficiently cleaned part remains in the pipe. And there was a fault that the bubble breakage after use worsens. In addition, there is a proposal (Patent Document 6) in which a stock solution composed of a surfactant, a foam stabilizer, and water has an aerosol injection speed in the range of 0.5 to 10 ml / second and an expansion rate on the water surface of 20 times or more. However, this is designed to cover the water surface of toilets, etc., to form foam, and to block odors from the toilet water surface and its surroundings for a certain period of time. Even if it is used, the liquid does not reach the inside of the complicated pipe, and the foam does not foam up to the opening of the drain. Therefore, the insufficiently cleaned part remains in the pipe and is used. There was a drawback that the subsequent bubble breakage worsened.

  An object of the present invention is to use a drainage pipe or a pipe having a simple composition and capable of efficiently removing dirt, bad odor, slime, etc. from the inside of the pipe to the drainage outlet or the pipe opening. The present invention provides a cleaning method using a viscous cleaning agent and an aerosol-type foam cleaning agent.

  As a result of intensive studies to solve the above-mentioned problems, the present inventor has surprisingly found that a cleaning agent containing a liquid composition containing an acylamino acid type surfactant and an inorganic alkali agent, or an increase in this amount, is surprisingly. Viscous cleaning agents for drain outlets or pipes that have a viscosity within the range of about 20 to about 500 cps with the addition of a viscosity agent, a viscosity modifier, etc., do not require complicated adjustments due to the combined use of two or more surfactants A cleaning effect could be obtained. In addition, by using isobutane and / or normal butane and compressed gas in combination as an aerosol propellant, it is possible to generate fine viscous foam with a large foam specific gravity that can reach the opening of the drain outlet from the inside of the pipe sufficiently. It was. Further, by providing a spray nozzle that can be attached to and detached from the aerosol pressure vessel, the liquid medicine reaches the S trap, and the generated medicine reaches the drain opening sufficiently to complete the present invention. It came.

  Thus, the present invention comprises (a) 0.2-20.0 wt% of an acylamino acid type surfactant and (b) 0.1-15.0 wt% of an inorganic alkali agent. A viscous detergent for mouth or pipe is provided.

  The present invention is also characterized by containing (c) 0.1 to 15.0% by weight of a thickener and (d) 0.5 to 20.0% by weight of a viscosity modifier or antifreeze. The above-mentioned viscous cleaning agent for drains or pipes is provided.

  The present invention also relates to (d) the drain outlet or the above-mentioned drain port, wherein the viscosity modifier or antifreezing agent is one or more selected from alcohols, aqueous glycols and hydrocarbons having a boiling point of 100 to 350 ° C. A viscous cleaning agent for pipes is provided.

  The present invention also provides the above-mentioned viscous cleaning agent for drains or pipes having a viscosity in the range of 20 to 500 cps.

  The present invention further provides (e) the above-mentioned viscous cleaning agent for drains or pipes, which contains 0.1 to 20.0% by weight of organic amine.

  The present invention further provides a method for cleaning a drain or pipe, wherein the cleaning agent is jetted from an auxiliary nozzle provided in a valve jetting part of an aerosol pressure-resistant container containing the aerosol-type foam cleaning agent. Is.

  According to the present invention, dirt, bad odor, slime, etc. on the drain outlet or pipe can be efficiently removed from the inside of the pipe to the opening. In particular, the aerosol-type viscous detergent containing isobutane and / or normal butane and compressed gas reaches directly into the water of the S-type trap part immediately after jetting, and the generated fine foam viscous material spreads sufficiently to the opening. Compared with the prior art, the cleaning property is remarkably improved and the foaming after the cleaning is excellent.

Hereinafter, the present invention will be described in more detail.
The drainage cleaner for a drainage outlet or pipe of the present invention is a viscous cleaning agent used for a drainage outlet or a pipe that is connected to a part having a pipe structure to the outside, such as a kitchen, a bathroom, and a bathroom. As shown in FIG. 1, the most general pipe structure is composed of a drain opening, a straight pipe and an S-shaped trap, followed by a pipe following the drain opening. The viscous cleaning agent for removing dirt, bad odor, substances causing slime, microorganisms, etc., mainly attached to the portion from the drain opening to the S-shaped trap is the drain cleaning agent for pipes or pipes of the present invention. . The main components of the agent that exhibits the cleaning effect of the viscous cleaning agent for a drain outlet or pipe of the present invention are an acylamino acid type surfactant and an inorganic alkaline agent. These contact or adhere to the drain or pipe pipe to remove dirt, bad odor, slime and the like.

  First, it is an acylamino acid type surfactant, but it is hypoallergenic and has recently been used for facial cleansers and hypoallergenic shampoos as a skin or environmentally friendly surfactant. There is a feature that generates When the acylamino acid type surfactant of the present invention is used as a viscous cleaning agent for drain outlets or pipes, a commercially available prior art cleaning agent generates a large amount of foam for cleaning immediately after use with a foaming agent. The rapid generation rather hinders the penetration of the cleaning agent into the inside of the pipe, whereas the fine bubbles generated gradually infiltrate into the pipe pipe and have the property of spreading widely. In particular, when used in an aerosol type, immediately after jetting, the liquid directly reaches the trapped portion of the water, and the generated fine foamy viscous material sufficiently spreads to the opening, and the cleaning effect is exhibited.

  Examples of the acylamino acid type surfactant to be used include, for example, N-acyl sarcosine acid type anionic surfactants such as sodium lauroyl sarcosine and lauroyl sarcosine; N such as coconut oil fatty acid sodium methylalanine and lauroylmethylalanine triethanolamine -Although an acylmethylalanine type anionic surfactant and lauroyl hydrolysis silk sodium can be mentioned, it is not limited to these.

  Examples of the inorganic alkaline agent used in the present invention include sodium hydroxide, potassium hydroxide, lithium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate, potassium bicarbonate, sesquicarbonate, alkali metal silicate, and alkali metal phosphorus. Examples of the acid salt may include, but are not limited to, acid salts.

  The acylamino acid type surfactant and inorganic alkali agent used in the present invention have a cleaning effect per se, but a synergistic cleaning effect can be obtained by using both in combination. The content of the acylamino acid type surfactant is 0.2 to 20.0% by weight, preferably 0.5 to 10% by weight, and the inorganic alkaline agent is 0.1 to 15.0% by weight. Can be included in the range of 3.0 to 10.0% by weight.

  The thickener and viscosity modifier of the present invention are for the purpose of increasing the cleaning effect by giving an appropriate viscosity to a cleaning agent containing a surfactant and an alkali agent, reaching the drain outlet and the pipe pipe, and adhering to the cleaning agent. Blended. In addition, in the case of an aerosol-type foam cleaning agent containing a propellant, it gives a moderate viscosity to the generated foam, and also affects other physical properties such as the specific gravity and fineness of the generated foam, and has a cleaning effect. There is work to raise. As the thickener, for example, a thickener produced by microorganisms such as xanthan gum and gellan gum; a cellulose-based thickener such as methylcellulose, ethylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, hydroxymethylpropylcellulose, carboxymethylcellulose; polyvinyl alcohol, Polyvinylpyrrolidone, N, N-dimethylaminoethylmethacrylic acid methacrylate copolymer diethyl sulfate, N-methacryloyloxyethyl N, N-dimethylammonium-α-N-methylcarboxybetaine / methacrylic acid alkyl ester copolymer, N-methacryloylethyl N, N-dimethylammonium-α-N-methylcarboxybetaine / methacrylic acid alkyl ester copolymer, carboxyvinyl polymer, Examples include carrageenan, tamarind gum, and saponin, but are not limited thereto. The blending ratio of the thickener may be 0.1 to 15.0% by weight, preferably 0.4 to 6.0% by weight, based on the total weight of the drainage outlet or the pipe viscous cleaning agent.

  Furthermore, alcohols, aqueous glycols, and hydrocarbons having a boiling point of 100 to 350 ° C., which are viscosity modifiers or antifreeze agents used in the present invention, are alcohols such as ethyl alcohol, isopropyl alcohol, and glycerin; Ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, polyethylene glycol, ethyl carbitol, ethylene glycol mono and diether, ethylene glycol esters, diethylene glycol ethers and ether esters, propylene glycol mono ether and ether esters, dipropylene glycol and Aqueous glycols such as monoethers; and octane, nonane, decane, undecane, etc., having a boiling point of about 100 to about 35 Although the it may be mentioned hydrocarbon ℃ not limited thereto. The blending ratio of the viscosity modifier or antifreeze agent is 0.5 to 20.0% by weight, preferably 2.0 to 15.0% by weight, based on the total weight of the viscous cleaner for the drain or pipe. it can.

  In addition, the viscosity of the drainage outlet or pipe cleaning agent of the present invention is in the range of 20.0 to 500 cps, preferably in the range of 50.0 to 150.0. The viscosity was measured using a small vibration viscometer # CJV5000 type (manufactured by A & D Co., Ltd.). The measurement was performed three times and obtained as a numerical range.

  The organic amine of the present invention is generally used as a cleaning aid, and examples thereof include, but are not limited to, alkanolamines such as monoethanolamine, diethanolamine, and triethanolamine. Moreover, although it is the compounding quantity of an organic amine, it is 0.1-20.0 weight% with respect to the weight of the whole drain cleaner or the viscous cleaning agent for pipes, Preferably 0.5-5.0 weight% can be mentioned. .

  Furthermore, the isobutane and normal butane used as the aerosol propellant of the present invention are not particularly limited as long as they are commercially available. Liquefied petroleum gas (LPG), which is a mixed gas of propane and butane, and dimethyl ether are propellants often used in ordinary aerosol products, but have a lower boiling point than isobutane and normal butane, combined with compressed gas, and the acyl of the present invention. When used as an aerosol-type foam cleaning agent containing an amino acid-type surfactant and an inorganic alkali agent, it does not become a straight liquid immediately after injection, and therefore the drug reachability to the S-type trap is low and is not suitable for use. A drug containing a propellant and a surfactant filled in an aerosol tube under high pressure is placed under a reduced pressure immediately after jetting, whereby the propellant expands rapidly and forms a foam. When normal butane is used in combination with compressed gas as a propellant, it is in a state where it is injected vigorously as if it were a liquid immediately after injection, that is, a straight liquid form. And good cleaning becomes possible.

  In addition, nitrogen, carbon dioxide, air, argon, chlorofluorocarbon, and the like can be used as the compressed gas of the present invention. Nitrogen gas is preferable as an environment-friendly, safe and highly effective gas.

  The mixing ratio of isobutane and / or normal butane and compressed gas is used within the range of 88.0: 12.0 to 96.0: 4.0, but the content is released by the rapid expansion of the propellant due to the reduced pressure. The composition and blending amount of the propellant used are adjusted so that the foam specific gravity of the foam to be generated is in the range of 0.04 to 0.250. When the foam specific gravity is less than 0.04, the foam is too light and the chemical solution does not reach the trap portion inside the drain port. Moreover, when it is 0.250 or more, the foam is heavy and has a high viscosity, and the foam cannot reach the entire pipe pipe up to the drain port.

  The content of the aerosol propellant in which isobutane and / or normal butane and compressed gas are used in combination is 1.0 to 8.0% by weight, preferably 2.% by weight based on the total weight of the aerosol-type drain outlet or the foam cleaning agent for pipes. It can be used in the range of 0 to 6.0% by weight.

  A drainage port or pipe cleaning method for injecting the cleaning agent from an auxiliary nozzle provided in a valve jetting part of an aerosol pressure-resistant container containing the above-described aerosol-type foam cleaning agent of the present invention will be described with reference to FIG. The auxiliary nozzle is not limited in shape and material as long as the medicine is injected from the drain opening (6 in FIG. 1) toward the inside of the pipe tube. For example, the auxiliary nozzle is a thin cone having a length of about 5 cm. Can be mentioned. This auxiliary nozzle sprays aerosol propellant and drug in a straight liquid state (7 in FIG. 1), minimizes adhesion to the pipe and reaches the drug directly to the underwater part of the S trap (1 in FIG. 1). It becomes possible to make it. In addition, if a protective cap (4 in Fig. 1) that can be attached to and removed from the aerosol pressure vessel together with the auxiliary nozzle is used, there is no risk of human exposure to drugs containing alkaline agents, and safe injection is possible. It becomes. The protective cap may be any shape and material such as a hemispherical shape, a triangular pyramid, and a quadrangular pyramid as long as it can be repeatedly used in a shape that closely contacts the drain opening. For example, a hemispherical protective cap made of resin having a diameter of about 5 cm to about 10 cm can be mentioned. In general, as shown in FIG. 1, it is preferable to have the same diameter as a cylindrical aerosol can (2 in FIG. 1) and to be easily attached to and detached from the top of the aerosol can like a cap. In aerosol cans, the valve injection part is usually attached in the form of a thin tube at the top of the can, and a button having a nozzle part is provided on this, and by pressing the button, medicine etc. are injected in a mist form However, in the case of FIG. 1, aerosol is injected by applying pressure to the valve at a position where the attached protective cap contacts the valve portion (3 in FIG. 1). The auxiliary nozzle (5 in FIG. 1) is attached to the valve injection portion at the tip of the valve portion as shown in FIG. Therefore, by using the protective cap and the auxiliary nozzle, it is possible to spray the foam cleaning agent safely and effectively.

  Further, the viscous cleaning agent for drains or pipes of the present invention includes, for example, surfactants other than the surfactants used in the present invention, foaming agents, bactericides, antibacterial agents, cleanings for drains or pipes such as fatty acids. Components that can be used in the agent can be appropriately blended.

  An embodiment of the present invention is exemplified as follows. Lauroylethanolamine is dissolved in an aqueous potassium hydroxide solution, and saponin, coconut oil diethanolamine, diethanolamine, propylene glycol, diethylene glycol monomethyl ether, and fragrance are added, mixed, dissolved, made into a stock solution, and sealed in an aerosol can. A normal butane and nitrogen gas, which is a propellant, is press-fitted into an aerosol-type drain or pipe viscous cleaner. A jet nozzle and an upper cap are attached to the obtained aerosol type drain outlet or pipe viscous cleaning agent, and the chemical solution reaches the underwater portion of the S trap when it is injected into the pipe from the drain opening, Gradually, foam is sufficiently formed from the inside of the pipe to the opening of the drain, and the chemicals contained in the foam adhering to the inside of the pipe pipe effectively cleans dirt and odors.

Evaluation of Detergency of Stock Solution 20.00 g of commercially available rapeseed oil, 0.25 g of sorbitan monooleate, and 0.10 g of oil red were mixed and dissolved in 60.0 ml of chloroform to obtain a stain agent. This was uniformly applied to a vinyl chloride test piece of 5.0 × 5.0 cm, and stored and dried at 30 ° C., thereby evaporating chloroform to obtain a test specimen. Next, the products 1 to 15 of the present invention and the comparative products 1 to 5 are uniformly applied to the specimen, and after about 1 minute, the specimen is immersed in water at 30 ° C. The degree of adhesion was observed visually to confirm the cleaning effect.

Detergency test using aerosol-type foam detergent 20.00 g of commercial rapeseed oil or salt-free butter, 0.25 g of sorbitan monooleate, and 0.10 g of oil red were mixed and dissolved in 60.0 ml of chloroform to obtain a stain agent. This was uniformly applied to a vinyl chloride test piece of 5.0 × 5.0 cm, and stored and dried at 30 ° C., thereby evaporating chloroform to obtain a test specimen. Next, about 2.0 to 2.5 g of each of the aerosol foam cleaning agents of the present invention products 16 to 25 and the comparative products 6 to 15 was sprayed on the test piece specimen, and after the foam disappeared, the test piece specimen was placed at 30 ° C. The sample was immersed in water, and the degree of adhesion of the stain agent to the test specimen was visually observed to confirm the cleaning effect on rapeseed oil or unsalted butter. At that time, the slime remaining on the surface was confirmed by rubbing with a fingertip, and the slime-inhibiting effect was confirmed.

Foam- breakability test The chemical | medical agent was sprayed from the aerosol type foam washing | cleaning agent of this invention products 16-25 and comparative products 6-15, and the grade of the foam which remain | survives at a nozzle tip was confirmed. In general aerosols, propellant propulsive force is not so strong, and many of them generate a foam with a volume immediately after injection. When the propelling force of the propellant is strong, the liquid is injected in a liquid state without generating foam immediately after the injection. These differences were compared in terms of bubble breakage according to the amount of foam remaining at the nozzle tip immediately after injection.

Measurement of Foam Specific Gravity Aerosol-type foam detergents of the present invention products 16 to 25 and comparative products 6 to 15 were left still in a 25.0 constant temperature water bath, and shaken up and down every 10 minutes, 25.0 ± 1 When the temperature reaches 0 ° C., a sample is taken into the hemispherical glass cup (about 100 ml) shown in FIG. Shake the sample well when collecting, take care not to get air in, and after about 3 seconds, use a glass plate to cut the excess sample so that it is the same height as the hemispherical cup cup, The sample in the heel portion is wiped off and weighed with a weighing meter that can read up to 0.1 g, and the foam specific gravity is calculated by the following formula.
_{F 3 = (W1-W3)} ÷ (W2-W3)
F ₃ : Foam specific gravity, W 1: Weight (g) when sample is placed, W 2: Weight when water is added (g), W ₃ : Weight of specific gravity cup (g)
However, the measurement is performed three times, and the average value is taken as the foam specific gravity. The smaller the value of the foam specific gravity, the larger the air content, that is, the larger the foam, and the larger the value of the foam specific gravity, the smaller the air content, that is, the finer the foam. When the foam is large, a phenomenon of clogging occurs at the entrance or in the middle of the pipe and it does not spread throughout the pipe pipe, or when the foam generated by the S-shaped trap rises in the pipe pipe toward the drain opening There is a possibility that a clogging phenomenon occurs and the opening is not reached. Therefore, the foam specific gravity that is an index of the size of the foam is measured.

By mounting the protective cap on the head of an aerosol type foam cleaning apparatus as shown in the chemical achievement Figure 1 to S-shaped trap portion was inverted, pressed against the drain outlet opening, ejecting the medication toward the S-shaped trap Then, the chemical solution reaching the S-shaped trap portion was examined. Depending on the composition of the undiluted solution and the propellant, a foam is formed immediately after injection, and the chemical solution does not reach the S-shaped trap, and forms a foam in the vicinity of the opening and a lid. On the other hand, if the injection speed is appropriate, the liquid reaches the S-shaped trap immediately after the injection, and then gradually forms a foam. The degree of arrival at the S-shaped trap is an index. The chemical solution reachability to the S-shaped trap portion of the inventive products 16 to 25 and the comparative products 6 to 15 was examined.

Evaluation results Tables 1 and 2 show the evaluation of the cleanability of the stock solution and the evaluation results of the aerosol-type foam cleaning agent.

Table 1 and Table 2 show the evaluation results of the inventive products 1 to 15 and the comparative products 1 to 5. Products 1 to 15 of the present invention have a viscosity for a drain or pipe containing 0.2 to 15.0% by weight of the acylamino acid surfactant according to claim 1 and 0.1 to 10.0% by weight of an inorganic alkali agent. It was a detergent and its viscosity was in the range of 20-130 cps. Moreover, the viscosity of the comparative products 1-5 was as low as 5-20. As shown in Tables 1 and 2, the evaluation results of the detergency are shown in Tables 1 and 2. Although the inventive products 1 to 15 are slightly adhered to the test solution and the cleaning is insufficient, most of the test solutions are similar to the comparative products 1 to 5. The detergency was clearly superior compared to the result that the adhering liquid remained or a considerable amount of adhering liquid remained and the washing was considerably insufficient.

Results of detergency test using aerosol-type foam detergents All the test pieces of the present invention 16-25 using isobutane or normal butane in combination with nitrogen as an aerosol propellant were completely washed in rapeseed oil and unsalted butter. It was removed to such an extent that slime was hardly felt, and a sufficient slime-suppressing effect was confirmed. Moreover, it was a result that foamability was also good, and the foam specific gravity was comparatively large in the range of 0.052-0.124, and showed that it was a fine foam in the range of 0.040-0.250. . Furthermore, the chemical solution reaching the S-shaped trap is that the products 16 and 23 of the present invention are straight liquid immediately after jetting, most of them reach the trap part water, and part of them adhere to the trap wall. I reached the department. The remaining present invention products 17 to 22 and the present invention products 24 and 25 are in a straight liquid state immediately after jetting and reach the trap portion water, and the generated foam reaches the drain opening, and as a result, the foam is sufficient in the pipe pipe. I spread throughout.

  On the other hand, comparative products 6 to 15 using liquefied petroleum gas (LPG) or LPG and dimethyl ether (DME) as a propellant are slightly adhered to the comparative products 6 to 9 in the cleaning test for rapeseed oil and unsalted butter. The remaining was insufficiently washed, and Comparative products 10 to 15 had almost no test solution attached and were hardly washed. In addition, the comparative products 6 to 9 showed a certain degree of slime suppression effect, but the comparative products 10 to 15 had a large degree of slime. Moreover, foamability was bad, and foam specific gravity was comparatively small in the range of 0.009-0.025, and it was outside the range of 0.040-0.250, and has shown that it is a big foam. Furthermore, as for the chemical solution arrival degree to the S-shaped trap, bubbles were generated in the vicinity of the outlet immediately after the jets of the comparative products 6 to 15, and the bubbles did not reach the trap.

  From these results, all of the products 16 to 25 of the present invention using isobutane or normal butane and nitrogen in combination as an aerosol propellant had very good detergency. In addition, the generated foam has good foaming properties, and when spraying with a nozzle attached to the tip, after reaching directly into the liquid of the S trap in a straight liquid state, a fine foam viscous material is generated and gradually spreads into the pipe pipe. Since the drug is sufficiently distributed to the opening of the drain outlet, it has excellent performance as a drain outlet or a foam cleaning agent for pipes, which is not found in conventional products.

  On the other hand, liquefied petroleum gas (LPG) or LPG and dimethyl ether (DME), which are commonly used as propellants, are inferior in detergency, and when a nozzle is attached to the tip, Immediately after, foam is generated, resulting in clogging in the vicinity of the drain opening, and the drug does not reach the inside of the pipe, let alone the S trap, so it is not suitable as a foam cleaner for the drain or pipe. It was confirmed that.

A state is shown in which a protective cap is attached to the head of the aerosol-type foam cleaning apparatus, the head is inverted, pressed against the drain opening, and the medicine is sprayed toward the S-shaped trap. Hemispherical cup used to measure foam specific gravity
