  The present invention provides a composition comprising a mixture of a fulvic acid-containing humic substance and clay, specifically a cleaning composition, and a rust remover or rust preventive composition for metal products.

  The present invention is described in detail below.

1. Fulvic acid-containing humic substance One of the active ingredients of the composition of the present invention is a fulvic acid-containing humic substance. This material has surface activity and antioxidant properties.

  The term “fulvic acid-containing humic substance” in the present invention refers to a substance containing at least fulvic acid (see the definition below) among humic substances (Yoko Tachibana and Tawari City, Trace Nutrients Research 22: 111-115 (2005 )). The fulvic acid-containing humic substance may further contain an impurity, humic acid (see the definition below), for convenience of purification. In the present invention, fulvic acid is an important active ingredient. In this specification, the term “humic substances” refers to organic components that are secondarily produced by decomposition of organic matter such as leaves and stems of plants by a wide variety of microorganisms, and are not classified as sugar, protein, lipid, etc. A generic name.

  In general, fulvic acid-containing humic substances are present in natural soils, lakes, seawater, etc., and can be obtained from humic substances produced in the humus process where plants, seaweed, phytoplankton, etc. are decomposed by microorganisms. Among them, fulvic acid (humic acid), humic acid (humic acid), and salts thereof are mainly included. Alternatively, the fulvic acid-containing humic substance can be obtained from a humic substance artificially produced by imitating a natural humic process. This humic substance contains a fulvic acid analog and a humic acid analog. In this specification, such a fulvic acid analog and a humic acid analog are also referred to as fulvic acid and humic acid, respectively.

  Fulvic acid is a humic substance that is the final product of organic matter such as plants, seaweed, and phytoplankton that is decomposed by microorganisms, and contains high-molecular organic acids that have a molecular weight of about 300 to about 3,000 that are soluble in acids and alkalis. A mixture, for example, a yellow supernatant obtained after humus soil is suspended in water. Fulvic acid can include minerals (metal ions) chelated by carboxyl groups and various elements in the molecular structure. In addition, fulvic acid is known to have antioxidant and antimicrobial effects.

  Humic acid is a humic humic substance that is a final product formed by the decomposition of microorganisms by microorganisms, etc., and is a polymer having a molecular weight of about 3,000 to several hundred thousand that is soluble in alkali but insoluble in acid. It is a mixture containing an organic acid.

  Thus, both fulvic acid and humic acid are a mixture containing a plurality of polyvalent organic acids containing many acidic functional groups such as carboxyl groups and phenolic hydroxyl groups in their molecules.

  The fulvic acid-containing humic substance is currently commercialized as an aqueous humic substance solution, and is sold, for example, as “Lead Up (registered trademark)” by T & G (Kumamoto). The lead-up is produced from an organic substance that does not contain harmful substances. For example, a commercially available lead-up 1 L contains about 0.15 to 0.2% by weight of fulvic acid. In the case of a dry powder obtained from 1 L of lead-up, about 1.5 to 2.0 g of fulvic acid is contained in about 25 g of the powder.

  Other fulvic acid-containing materials include purified fulvic acid, but no humic acid, “Chelate Balance®” and “Beauty Source Ki-Tame®” (in this specification, simply “ (Also referred to as “chelate”) ”(Miyamonte Japan (Hyogo)), etc. are known. The chelate balance and chelate components are shown in Table 1 below.

  The fulvic acid-containing humic substance can be subjected to evaporation and purification of water, and can also be in a solid form such as a powder. Moreover, it can also refine | purify from this humic substance and can obtain substantially pure fulvic acid. Such solids such as powder and purified fulvic acid are fulvic acid-containing humic substances in the present invention, together with a fulvic acid-containing aqueous solution. In this specification, a fulvic acid containing humic substance may consist only of fulvic acid.

  The fulvic acid-containing humic substance is desirably in any form of solid form (eg, powder, granule, pellet, etc.) or liquid form (eg, solution, suspension, etc.).

  The content of the fulvic acid-containing humic substance in the composition of the present invention is an amount that exhibits a cleaning effect or a rust-removing / rust-preventing effect when used together with clay, regardless of whether the composition is in solid form or liquid form. For example, fulvic acid is about 0.0001% to about 5% by weight, preferably about 0.001% to about 1% by weight, more preferably about 0.1% to about 0.5% by weight, but not limited thereto. To do.

2. Clay Another active ingredient of the composition of the present invention is clay.
The clay that can be used in the present invention is an aluminosilicate clay, and examples thereof include montmorillonite-containing clay such as bentonite, acid clay, and activated clay, and montmorillonite. As the montmorillonite, sodium type montmorillonite is preferable. Acid clay and activated clay are used as an adsorbent for impurities and as a decolorizing agent, and can be used as bentonite substitute clay in the present invention.

  The clay may be in either a dry form (eg, powders, granules, pellets, etc.) or a wet form (various shapes of solids, suspensions, etc.).

  The clay content in the composition of the present invention is an amount that exhibits a cleaning effect or a rust removing / rust preventing effect when used together with a fulvic acid-containing humic substance. When the composition is liquid, for example, a ratio of 0.0015 to 0.2 (dry part by weight) of fulvic acid: about 5 to 25 (dry part by weight) of clay .

3. Composition The composition of the present invention is characterized in that it contains a fulvic acid-containing humic substance and clay as described above.

  The aqueous solution of a fulvic acid-containing humic substance is usually acidic (for example, pH 2.0 to 4.0). By mixing clay with this, the pH of the solution becomes weakly alkaline (for example, about pH 8).

  The composition can be either liquid or solid, or can be either concentrated or diluted. Moreover, the shape of a composition is arbitrary.

  When the composition is a liquid, it may have any shape such as a bottle type, a bottle type with a measuring cap, and a spray type. The liquid is in the form of a suspension because the clay is insoluble in water. At this time, by using nano-sized ultrafine particles as clay, sedimentation of clay in the liquid composition can be suppressed and the suspended state can be maintained.

  When the composition is solid, it can be in any shape such as powder type, granule type, tablet type, stick type, sachet (ie, sachet) type, paste type, and the like. In particular, in the case of shapes such as a sachet type, a stick type, and a tablet type, it can be a prescription form for one-time use. In the case of the sachet type, the material of the sachet that contains the composition is a water-soluble material such as starch or gelatin, and the sachet can preferably contain a powdery or granular composition. . In the case of tablet type, stick type and the like, a binder (eg, water-soluble dextran, hydroxypropylcellulose, etc.), a disintegrant (eg, starch, Cellulose-based additives such as water-soluble types, or a form that floats on the water surface by adding a foaming agent (for example, sodium bicarbonate, etc.) into tablets and sticks It can be. In the case of paste type, it can be obtained by adding fulvic acid-containing humic substance aqueous solution and water appropriately to dry clay and mixing. Such a paste type has, for example, a usage form in which it is applied to a rust portion of a metal, or the paste can be suspended in water and used as a cleaning agent.

  When the composition is in a concentrated form, it is a composition that can be used in a diluted state in water by weighing a predetermined amount from the composition. Since this composition has a cleaning effect or a rust removal / rust prevention effect, the predetermined amount may be an amount that can exhibit the cleaning effect or the rust removal / rust prevention effect. The dilution factor of the composition in concentrated form is not particularly limited, but is, for example, about 10 to 5,000 times.

  As used herein, “cleaning effect” refers to the synergistic cleaning effect of fulvic acid-containing humic substances and clay. “Synergistic” means that the surfactant action of fulvic acid-containing humic substances is enhanced by clay.

  As used herein, “rust removal / rust prevention effect” refers to a rust removal / rust prevention effect caused by humic substances containing fulvic acid and clay. It has been known that fulvic acid-containing humic substances have a rust-preventing effect due to antioxidant action, but when combined with clay, not only the rust-preventing effect but also the rust removal effect of metal products is exhibited. .

  The composition of the present invention contains, for example, a ratio of about 0.0015 to 0.2 (dry part by weight) of fulvic acid: 5 to 25 (dry part by weight) of clay when used once in either liquid form or solid form. It is preferred to include fulvic acid-containing humic substances and clays in an amount.

  The content of the fulvic acid-containing humic substance in the composition of the present invention is not limited to the following range, for example, from about 0.0001% by weight to about 5% as fulvic acid regardless of whether the composition is in solid form or liquid form. % By weight, preferably from about 0.001% to about 1% by weight, more preferably from about 0.1% to about 0.5% by weight, but not limited thereto.

  The content of clay in the composition of the present invention is not limited to the following range, but when the composition is a solid, for example, it is about 50 wt% to about 99.99 wt% as a dry weight. Is a liquid content satisfying a ratio of about 0.0015 to 0.2 (dry parts by weight) of fulvic acid: about 5 to 25 (dry parts by weight) of clay.

  The composition of the present invention can further be used in detergents and the like, other surfactants (soap detergents, synthetic detergents, etc.), coloring agents, fragrances (herbs, fruit juice extracts, fragrances, etc.), antifouling agents, Enzymes (lipase, cellulase, protease, etc.), builders (zeolite, sodium carbonate, sodium silicate, etc.) may be contained.

  As will be described below, specific examples of the composition of the present invention include a cleaning composition and a rust removing or rust preventing composition.

(1) Cleaning composition and method One specific example of the composition of the present invention is a cleaning composition, which can be used for cleaning an object to be cleaned.

  The composition can be used for efficient cleaning of objects to be cleaned such as towels soiled with a considerable amount of oil, such as sesame oil, castor oil, olive oil and the like, which come in large quantities from the esthetic industry, for example. It was difficult to efficiently remove such towels with existing detergents, and it was not easy to remove the smell of oil and to restore the original plump feeling after finishing. When using the composition of the present invention to wash an object to be cleaned which is considerably contaminated with such oil, a substantial amount of oil can be removed by first soaking and washing. In this case, most of the oil can be removed by washing using another detergent as the secondary detergent or using a combination of another detergent and the composition of the present invention, There is almost no oily odor, and it can be finished to the original touch of the towel. Alternatively, the same effect can be achieved by using a combination of the composition of the present invention and another cleaning agent, preferably a soap detergent, as the primary cleaning agent, instead of soaking. Such effects are unexpected and surprising.

  As described above, the composition of the present invention can be effectively used for cleaning an object to be cleaned, which is very dirty such as contaminated with a large amount of oil (oil / fat) and difficult to remove with a normal detergent. It is.

  The cleaning composition of the present invention contains a fulvic acid-containing humic substance and clay as active ingredients, and can exhibit a cleaning effect without the need for other chemical substances. For example, soap detergent (fatty acid sodium), synthetic detergent (for example, surfactant such as sodium linear alkylbenzene sulfonate, sodium alkyl sulfate ester, sodium alkyl ether sulfate ester, polyoxyethylene fatty acid alkanolamide, sodium alkyl sulfonate, etc. Etc., preferably a soap detergent which is an environmentally friendly detergent can be added and mixed. When washing persistent dirt such as oil and mold, effective cleaning is possible by combining the composition of the present invention with another cleaning agent.

  The cleaning composition is in the form of a normal liquid detergent (concentrated type, weighing type, spray type, etc.), and a normal solid detergent form (powder type, cleanser type, granule type, tablet type, paste type, sachet type, etc.) Either of these may be used.

  Examples of items to be cleaned are not particularly limited, but contain items other than those that are easily damaged by clay, such as sinks, ranges, ventilation fans, burnt fish nets and pans, kettles, and other cooking utensils , Kitchen utensils such as tableware, bathtubs, tiles, moldy joints, shower hoses, plastic items, bathroom utensils such as mirrors and currants, wooden and vinyl floors, wooden and vinyl wallpaper, and housing items such as window glass, Sanitary ware, currants, wooden / vinyl floors, toilet articles such as wooden / vinyl walls, household clothing, commercial clothing, and cloths such as towels with terrible oil stains from the esthetic industry, etc. However, it is not limited to these. The composition of the present invention can be used for washing vegetables such as cucumber, cabbage, lettuce, and tomato, and foods such as apple, pear, strawberry, and grapefruit. Furthermore, the composition of the present invention can be used for washing animals including humans. For example, the composition of the present invention can be used to wash the human body and face, or used as a shampoo or spray to wash animals, eg pets such as dogs and cats, and domestic animals such as pigs and cows. You can also. The composition of the present invention has features that it is effective for preventing rough skin as well as preventing allergies.

  Moreover, the composition of this invention can also be used as a stand-type cleaning agent for toilets. In this case, a deodorizing effect and a cleaning effect can be expected simply by placing the dried composition of the present invention in a solid form in a hand-washing bowl of a toilet.

  Furthermore, the composition of the present invention can also be used as an indoor deodorizing spray or a pet deodorizing spray.

  The present invention also provides a cleaning method including cleaning an object to be cleaned using the above composition.

  Cleaning can be performed, for example, by soaking before main cleaning, cleaning in a household washing machine, cleaning in the cleaning industry, cleaning oil stains, cleaning mold, cleaning dishes, and cleaning rusted metal. Including but not limited to.

  Weigh a specified amount of the detergent composition (above), dilute with water as necessary, or suspend in water, then apply the composition to the substance to be cleaned, spray, add, etc. To do.

  The amount of water at the time of washing can be appropriately selected. For example, 30 L to 50 L of water can be used for washing in a household washing machine. The washing temperature is preferably about 20 ° C to 45 ° C.

  Washing can be performed once or more than once. The cleaning may be performed in the first cleaning using only the composition of the present invention or a combination of the composition of the present invention and another cleaning agent. If necessary, the second wash can be cleaned using another cleaning agent or a combination of the composition of the present invention and another cleaning agent. After washing, rinse with water.

(2) Rust removal or rust prevention composition and method The present invention further provides a rust removal or rust prevention composition.
The present invention also includes spraying or applying the composition onto a rusted metal material to remove the rust of the material or prevent the material from rusting, or Providing a method for rust prevention.

  In the examples described later, as a result of experiments using rusted cucumbers, it was surprisingly found that the composition of the present invention is effective for removing rust. Although the antioxidant action of fulvic acid was known, it was not known that it could not only prevent rust but also remove metal rust.

  The metal and the composition are brought into contact with each other by a method such as applying the composition to a rusted portion of the metal or immersing the rusted metal in the liquid of the composition, and leaving it for about 30 minutes or more.

  Although metal rust, especially iron products, is removed mechanically with a brush, it is difficult to completely remove rust. The composition of the present invention is brought into contact with such rust and mechanically rubbed as necessary, and then left for a predetermined time to remove the rust. The paste type of the composition of the present invention may be applied to the rust portion of the metal column.

  In the composition for removing rust or preventing rust, the amounts of fulvic acid-containing humic substances and clay as active ingredients are the same as those for the cleaning composition described above.

  Any article with metallic rust can be used in the method of the present invention. Examples of such articles can include, but are not limited to, sinks, ranges, cookware, kitchen knives, scissors, bicycles, and verandas and emergency stair railings.

  For example, in the case of a knife, the knife can be inserted and stored in a knife storage container filled with a paste-type composition. As a result, rust can be prevented and rust can be removed at the same time.

  The following examples further illustrate the present invention, but the scope of the present invention is not limited by these examples.
