Disinfection and Deodorization Using Mineral and Sulfur [0002]

The present invention relates to a disinfecting and deodorizing agent using minerals and sulfur. More specifically, the present invention relates to environmentally friendly disinfecting and deodorizing agents by mixing sodium metasilicate, potassium carbonate, potassium citrate, borax, potassium iodide and sulfur as main components. The present invention provides a disinfection and deodorant that is environmentally friendly, and does not cause harm to the human body because the far-infrared rays continuously generated from silicon, borax, and potassium contained in the environmentally-friendly disinfection and deodorizing agent and exhibits disinfection and deodorizing effect against the contaminants.

Deodorants are substances used to remove odors. Odors are generated by substances that can be perceived by the human sense of smell. In addition to abominable facilities such as wastewater treatment plants, odorous substances including ammonia are present in many places in our daily lives. Sulfur compounds such as hydrogen sulfide and mercaptan, nitrogen compounds such as ammonia, scatole and amine, fatty acids such as formic acid and acetic acid, and the like are included. In recent years, as the standard of living improves, stinks that discomfort the living are defined as pollution and the regulations are strengthened by the relevant laws and regulations.

Conventional deodorization methods for removing such odors include a chemical deodorization method in which fragrance or fragrance is used to complement the olfactory sense, a chemical deodorization method in which oxidation, reduction, neutralization, or addition reaction is used to decompose, and a method in which a porous material such as activated carbon or silica gel , And a biological deodorization method in which microorganisms or enzymes are used to cut off the water. However, the natural fragrance and synthetic fragrance in the chemical deodorization is so many that the unknown ingredient is not revealed, while the toxicity causes the respiratory and skin troubles to easily occur, and the physical adsorption method is repeatedly carried out as the temperature rises and the pressure increases And the biological deodorization method is not stable because its activity difference is large depending on the temperature and humidity conditions. Although chemical deodorization is the most promising field of development, it still has limitations in ensuring satisfactory deodorizing power by itself.

Conventional deodorants made of chemical components are not only harmful to the human body but also harmful chemical components are not purified in the course of deodorization and discharged as they are or discharged to the air, thereby becoming a second environmental pollution source such as polluting water quality and atmosphere The fragrance or the naphthalene which is used to remove the odor is chemically reacted with the molecular structure of ammonia, that is, NH _3, and the molecular structure of ammonia is changed, so that the odor can not be decomposed and removed. Naphthalene is an indirect deodorizing function which causes a stronger odor than the odor to be decomposed and removed, thereby preventing the user from feeling odor due to ammonia. This deodorant diffuses a stronger odor than conventionally generated odor, so that the user can not distinguish the odor by the strong smell of the chemical component, rather than removing the odor, so that the odor is removed, It is merely causing the removal effect.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide an environmentally friendly disinfection and deodorant.

The present invention relates to a disinfecting and deodorizing agent comprising sodium metasilicate, potassium carbonate, potassium citrate, borax, potassium iodide and sulfur.

Hereinafter, the components of the disinfecting and deodorizing agent of the present invention will be described in more detail.

The present invention relates to a disinfection and deodorant composition comprising sodium metasilicate, potassium carbonate, potassium citrate, borax, potassium iodide and sulfur.

The disinfecting and deodorizing agent may be, for example, 10 to 50 parts by weight of sodium metasilicate, 10 to 50 parts by weight of potassium carbonate, 1 to 10 parts by weight of potassium citrate, 1 to 10 parts by weight of borax, 1 to 20 parts by weight of potassium iodide, and 1 to 10 parts by weight of sulfur.

More specifically, for example, the disinfecting and deodorizing agent may contain 20 to 40 parts by weight of sodium metasilicate, 30 to 50 parts by weight of potassium carbonate, 2 to 6 parts by weight of potassium citrate, 1 to 6 parts by weight of borax, 5 to 5 parts by weight of potassium iodide, 2 to 8 parts by weight of potassium iodide, and 1 to 5 parts by weight of sulfur.

In the present invention, sodium meta silicate (Na ₂ SiO ₃ ) is used as an alkali builder to increase the hardness (hardness, alkalinity) and the pH so that the required amount of potassium carbonate can be sufficiently dissolved and the alkali condition It strengthens the detergency, neutralizes the fat, keeps it odorless, promotes the interfacial activity, and increases the microbial penetration and sterilization effect. The content is not limited, but can be adjusted as needed. For example, it is preferable to use 10 to 50 parts by weight, more preferably 20 to 40 parts by weight, of the solid content with respect to 100 parts by weight of water, because the disinfecting effect and irritation to the human body are not given.

The potassium carbonate (K ₂ CO ₃ ) is an alkaline disinfectant in the form of a white powder. It disinfects and removes viruses, bacteria, and the like that generate odor or spread disease. It is also used as a main component of disinfectant. It is relatively soluble in water and does not have irritating odor as compared with chlorine oxidizer, and exhibits powerful disinfecting effect by strong far-infrared radiation. The potassium carbonate is a stable substance that is not reactive with each other in an aqueous solution, and is stored in a powder state to ensure storage stability and preservability. In order to increase the sterilizing power and the deodorizing power, it is preferable to use 10 to 50 parts by weight, more preferably 30 to 50 parts by weight, of the solid content with respect to 100 parts by weight of water, but it is not limited thereto.

The potassium citrate (C ₆ H ₅ K ₃ O ₇ ) is a colorless or white crystalline or powdery substance. Potassium is ionized together with potassium carbonate to increase the hardness, increase disinfection effect by its sterilizing action, and act as a pH regulator which suppresses alkalization of the composition excessively due to the use of potassium carbonate and sodium metasilicate. In this case, although the content is not limited, for example, it is preferable to use 1 to 10 parts by weight, more preferably 2 to 6 parts by weight, of the solid content with respect to 100 parts by weight of the water, This is preferable because it is in a range that does not give stimulation.

The borax (Borex: Na ₂ B ₄ O ₇ ) is a colorless plate-like or mono-columnar crystal belonging to monoclinic system. Sterilizing and preserving, it disinfects microorganisms decomposing organic wastes or prevents organic wastes from being spoiled to prevent odor, and emulsifies fats and oils to prevent odor due to oxidation of fats. The content is preferably 1 to 10 parts by weight, more preferably 1 to 5 parts by weight, based on 100 parts by weight of the water, in order to increase the sterilizing power and deodorization power It is preferable.

Potassium iodide (KI) is used for the purpose of increasing sterilizing power and cleaning power. In this case, the solid content of the water is preferably 1 to 20 parts by weight, more preferably 2 to 8 parts by weight, based on 100 parts by weight of the water.

Sulfur (S) is used to improve disinfection and sterilizing power. Sulfur is used to disinfect skin bacteria, eczema, athlete's foot, dandruff and skin keratin, and it is also used as a disinfectant for crops. However, since sulfur is not soluble in water, it is possible to solve this problem by adding sulfur to water at 140 to 160 ° C and stirring the slurry in the form of a slurry, adding the slurry to water at 80 to 90 ° C and stirring. In this case, the content can be appropriately adjusted as needed. For example, it is preferable to use 1 to 10 parts by weight, more preferably 1 to 5 parts by weight, of the solid content with respect to 100 parts by weight of the water It is desirable to achieve the object as a disinfection and deodorant.

In the present invention, the deodorization rate (%) of the disinfection and deodorizing agent is measured by KS I 2218: 2009 when the components and the content range are used, and the amount of ammonia is 90-100%, the amount of hydrogen sulfide is 95-100% 70%. ≪ / RTI > The antimicrobial test was carried out in accordance with the test standard of KCL-FIR-1002: 2011, and the bacteria of Escherichia coli, yellow grape normal group and Salmonella were reduced.
