Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition, and more particularly, to a plumbing system such as a kitchen, a bathroom and a toilet, and a plastic product and a tile product used in the plumbing system. Suitable for cleaning plastics and tiles, stones, glass, concrete blocks, etc., which are contaminated with multiple contaminants such as water ash, iron rust and other metal oxides, animal and vegetable oils, molds, etc. The present invention relates to an agent composition.

[0002]

2. Description of the Related Art At present, around water such as kitchens and bathrooms,
Plastic products and tile products are often used. However, these plastic products and tile products used around the water are subject to long-term use, such as water rust, iron rust and other metal oxides, resinified animal and vegetable oils, molds, and other contaminants. Adhere to the surface and become contaminated. Conventionally, methods for removing these contaminants include a method of washing with a synthetic detergent using a surfactant, a method of physically removing the substance by polishing with an abrasive such as a cleanser, and a method of chemically removing the substance with an acid or a bleaching agent. For example, a method of removing it has been used.

[0003] However, it is difficult to remove the above-mentioned complex contamination, particularly iron rust and other contaminants such as metal oxides, by a method of washing with a synthetic detergent or the like. In addition, in the conventional methods of decontamination, such as the physical method of polishing with a cleanser or the chemical decontamination method using acids or bleaching agents, even if the contamination can be removed, the surface of the plastic or tile also becomes brittle at the same time. In some cases, the surface of the product may be damaged, for example, by scratching, losing luster, or discoloring. Furthermore, handling of acids and bleaching agents requires care.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems in the prior art for removing contamination of plastics and tiles, and thus, it is possible to reliably remove the contamination and at the same time to attack the surface of plastics and tiles. An object of the present invention is to provide a detergent composition which can be easily removed of contaminants by washing with water and has no danger of handling.

[0005]

In order to achieve the above object, the cleaning composition according to the present invention comprises 5 to 60% by weight of sodium thioglycolate, 0.1 to 5% by weight of sodium ethylenediaminetetraacetate, Ethanolamines
1 to 5% by weight and the remaining amount is composed of water. The detergent composition contains 0.1 to 10% by weight of a surfactant, 1 to 20% by weight of a solvent, 0.1 to 10% by weight of a thickener, a fragrance, a deodorant, a disinfectant, and a preservative. Agents and other additives can be blended.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Sodium thioglycolate in the detergent composition of the present invention reacts with iron rust to form a chelate compound, solubilized in water and made removable. The amount of sodium thioglycolate in the detergent composition is in the range of 5 to 60% by weight, preferably 10 to 40% by weight. If the amount of sodium thioglycolate exceeds 60% by weight, the stability of the cleaning composition at low temperatures is undesirably reduced. If the content is less than 5% by weight, the desired removal effect by solubilization of iron rust may not be achieved.

[0007] Sodium ethylenediaminetetraacetate in the detergent composition acts as a metal sequestering agent, solubilizing metal oxides other than iron rust in water so that they can be removed. The amount of sodium ethylenediaminetetraacetate in the detergent composition is in the range of 0.1 to 5% by weight, preferably 0.5 to 3% by weight.

[0008] Ethanolamines in the detergent composition include:
It acts as a cleaning aid and at the same time acts as a pH adjuster. Examples of ethanolamines include triethanolamine, diethanolamine, monoethanolamine, and the like. The amount of ethanolamines in the detergent composition is in the range of 0.1 to 10% by weight, preferably 0.5 to 5% by weight. Further, it is preferable to adjust the pH of the cleaning agent so as to be in the range of 7 to 8.5.

The detergent composition of the present invention contains sodium thioglycolate, sodium ethylenediaminetetraacetate and triethanolamine as essential components as described above, and a surfactant is further added thereto to form a detergent composition. In addition to making the components well penetrate into contaminants, the effect of removing contaminants such as animal and vegetable oils is improved. As the surfactant, an anionic surfactant or a nonionic surfactant can be used. Examples of the anionic surfactant include sodium alkylbenzene sulfonate, sodium alkyl sulfate, sodium dialkyl sulfosuccinate, sodium polyoxyethylene alkyl ether sulfate, polyoxyethylene alkyl ether, and polyoxyethylene alkyl phenyl ether. Examples of the nonionic surfactant include polyoxyalkylene (ethylene) alkylphenyl ether, polyoxyalkylene (ethylene) alkyl ether, polyoxyethylene polyoxypropylene block copolymer, polyoxyethylene glycol alkyl ester, sorbitan fatty acid ester, and sucrose fatty acid. Esters and the like. The amount of these surfactants is 0.1 to 10 in the detergent composition.
% By weight.

Further, by adding a solvent to the above-mentioned cleaning composition, the contaminants are dissolved by the solvent, and the cleaning effect can be further enhanced. As the solvent, an alcohol solvent, a cellosolve solvent, a hydrocarbon solvent, aqueous ammonia, or the like can be used. Examples of the alcohol solvent include ethanol and isopropyl alcohol. As cellosolve solvents, mythyl cellosolve,
Ethyl cellosolve, butyl cellosolve, phenyl cellosolve and the like can be mentioned. The compounding amount of these solvents is 1 to 20% by weight in the detergent composition, and when a cellosolve-based solvent and an alcohol-based solvent are used in combination, the amounts are 1 to 10% by weight, respectively. Is preferred. In the case of a cellosolve-based solvent, it is not preferable to mix a large amount of the solvent because the solvent may damage the surface of the plastic product.

Further, by adding a thickening agent to the cleaning composition of the present invention, the viscosity of the composition is adjusted, so that a cleaning agent in a desired form from liquid to gel can be obtained. . That is, the viscosity can be increased by adding a thickener to the cleaning composition, so that the cleaning composition can be applied to a vertical surface. Examples of the thickener include water-soluble polymers such as polyacrylamide and polyvinyl alcohol, and carboxymethylcellulose and methylcellulose. The amount of the thickener is within a range that can be adjusted to a viscosity according to the use of the cleaning composition, but is usually 0.1 to 10 in the cleaning composition.
% By weight.

In addition to the above components, the detergent composition of the present invention may contain various additives such as fragrances, deodorants, disinfectants, and preservatives. Examples of flavors include natural flavors, synthetic flavors, and food flavors. Examples of the deodorant include plant essential oils, plant extracts, and chemical substances such as chlorine dioxide. Examples of the disinfectant include an amphoteric surfactant, a cationic surfactant, and an active soap. Further, as a preservative, sodium dehydroacetate (DH)
A) and the like. The amount of these additives is not particularly limited, but usually is 5% by weight or less.

The cleaning composition according to the present invention as described above can be used in a liquid state or a gel state. The cleaning method is the same as that of a general cleaning method, by applying the cleaning composition to an object to be cleaned. Spraying and cleaning with a cloth or sponge and hand-wiping or brushing, or, in cases of severe contamination, immersing the object to be cleaned in a cleaning agent solution or gel-like cleaning agent Depending on the degree of contamination, there is no particular limitation on the cleaning method, such as a method in which the cloth is left for about 10 minutes to several hours, then wiped manually with a cloth or sponge, or cleaned with a brush or the like.

[Cleaning test] A commercially available porcelain tile (97 mm)
× 97mm × 5mm), black tray made of melamine resin, bat made of acrylonitrile-styrene resin (AS resin),
A polypropylene bat and a wooden floorboard (Eagle Floor 2 DB, manufactured by Daiken Kogyo Co., Ltd.) were immersed in a dilute hydrochloric acid solution for 20 minutes, and then thoroughly washed with 5 metal office clips, 5 metal hairpins, and 18 iron. A cut liter can (20 mm x 50 mm x 1 mm) was placed on the object and left outside for 2 weeks. During this time, the object was rusted daily with a washing bottle. Various cleaning agents were coated or dropped in a circular shape having a diameter of about 2 cm on these rusted objects, left for 1 hour, washed with water, and the state of rust removal was visually checked and evaluated according to the following evaluation criteria. In the case of a cleanser, it was applied to a rusted portion of the object and polished using a kitchen sponge. Table 2 shows the test results.

[Evaluation Criteria] 5: Rust was completely removed. 4: Almost all rust was removed. 3: A little rust was removed. 2: Rust can hardly be removed. 1: Rust cannot be removed at all.

[0019]

[Table 2]

As is clear from the results shown in Table 2, according to the cleaning composition of the present invention, rust adhering to tile products, prestic products and the like can be reliably removed.
On the other hand, in the case of hydrochloric acid, although most of the rust could be removed, the surface was eroded except for the porcelain tile and the AS resin, resulting in a trace. Further, in the case of oxalic acid, rust cannot be removed so much, and rust can hardly be removed with a household detergent. Furthermore, although the rust could be completely removed by polishing with a cleanser, the surface of each product was scratched and lost its luster.
