Abstract: PURPOSE:To obtain the subject composition which has a high bleaching power and no irritative small and is suitable for the removal of dirt on the hard surfaces of toilets, baths, etc., by mixing an H2O2-related compound, an organic peroxy acid precursor, a water-soluble salt containing a transition metal atom, and a surfactant. CONSTITUTION:The objective composition comprises (A) H2O2 or a peroxide (e.g. sodium percarbonate), (B) an organic peroxy acid precursor which reacts with H2O2 to produce an organic peroxy acid of the formula (wherein R is a 1-5C alkyl or alkenyl group that may be substituted; R is a 1-8C alkylene group that may be substituted or a phenylene group that may be substituted by a 1-5C alkyl; A is a 2-4C alkylene group; and (n) is 0-100) (e.g. ethylene glycol diester of methoxyacetic acid), (C) a water-soluble salt containing a transition metal atom (e.g. ferric chloride), and (D) a surfactant (e.g. lauryl glycoside). The effective oxygen concentration in use should be adjusted to 0.1-3wt.%. For use, the components A and B are mixed together, and water is added to the mixture as required. The resultant mixture is applied to a surface to be bleached and cleaned, to which the component C is then applied.

Abstract: PURPOSE:To improve the effect of bleaching and cleaning a hard surface by treating the surface with an aqueous solution of a specific organic peroxy acid under specified conditions. CONSTITUTION:A bleaching agent composition comprising H2O2 or a peroxide (e.g. sodium percarbonate) and an organic peroxy acid precursor which reacts with H2O2 to yield an organic peroxy acid of the formula (wherein R is a 1-5C alkyl or alkenyl group that may be substituted; R is a 1-8C alkylene group that may be substituted or a phenylene group that may be substituted by a 1-5C alkyl; A is a 2-4C alkylene group; and (n) is 0-100) (e.g. diester of 3,6-dioxaheptanoic acid with ethylene glycol) is used in two ways. One process comprises bringing a hard surface into contact with an aqueous solution of the bleaching agent composition having a pH of 7.5 or more, allowing the system to stand for 5-30min, reducing the pH of the solution to less than 7.5, allowing the system to stand for 5-60min, and rinsing the surface. Another process comprises allowing an aqueous solution of the bleaching agent composition having a pH of 7.5 or more to stand for 5-30min, reducing the pH to less than 7.5, bringing a hard surface into contact with the resulting solution for 5-6min, and rinsing the surface.

Abstract: PURPOSE:To obtain a household water purifying device at a low cost by laminating an unwoven cloth having a specified basis weight and an apparent density consisting of an active carbon fiber and a synthetic binder fiber and use it as the filter medium. CONSTITUTION:The active carbon fiber (e.g. pitch base active carbon fiber 1) and the synthetic binder fiber (e.g. conjugate fiber of a high melting polypropylene and low melting polyethylene having core/sheath structure) are mixed and screened, and fused to obtain the unwoven cloth having 50-200g/m basis weight and 0.03-0.15g/cm apparent density laminated and used as the filter medium. For example, a filter type water purifying device is made from the unwoven cloth 1, paper 2, nylon mesh 8 and vessel 4. Consequently, the household water purifying device is obtained at a low cost.

Abstract: PURPOSE:To obtain a removing matter capable of removing only a chlorine smell by injecting an acetic acid solution of chitosan having specific properties in an alkali solution from a nozzle to spin the same into fibrous chitosan having a specific diameter and subjecting said chitosan to a dry nonwoven fabric forming process or wet papermaking process. CONSTITUTION:An acetic acid solution of chitosan of which the deacetilation degree is 60% or more and the viscosity measured when chitosan is dissolved in a 1% acetic acid solution in a ratio of 35wt.% is 1000-25000cps (30 deg.C) is prepared. This solution is injected in an alkali solution from a nozzle to perform spinning. The diameter of fibrous chitosan is set to 5-80mum. This fibrous chitosan is subjected to a dry nonwoven fabric forming process or wet papermaking process as it is or along with other fiber. In this case, fibrous chitosan and a natural fiber such as a wood pulp fiber are desirably used in a specific ratio. By this method, a chlorine smell removing matter not removing other substances such as trihalomethane type substance, heavy metals or org. matter in tap water but selectively removing only a chlorine smell can be obtained.

Abstract: PURPOSE:To stabilize or increase a volatile amount with a time of perfume from an aromatic substance and to continue even diffusion of an aroma by a method wherein with the decrease in the weight of a drug with which a container is filled, the center of gravity of the drug is displaced and the volatile surface of the horizontally-positioned drug is rotated by a specified amount. CONSTITUTION:A drug decreased along with volatilization of the drug and a container filled with the drug are provided. Resulting from a decrease in the weight of the drug with which the container is filled, the center of gravity of the drug is displaced, and the volatilizing surface of the horizontally- positioned drug is rotated at least in a 90 deg. arc. An aromatic substance 1 is decreased in weight through volatilization of perfume from the volatilizing surface in a horizontal direction of the aromatic substance, and the volatilizing surface gradually approaches the bottom side. As a result, the center of gravity of the aromatic substance 1 is gradually displaced leftward from the position of the axis of the container 2, and rotation moment by which the container 2 is rotated counterclockwise around a rotary axis 5 is generated. The volatilizing surface of the aromatic substance 1 is inclined gradually, and with the progress of volatilization of the aromatic substance 1, its inclination is increased.

Abstract: PURPOSE:To remove chlorine odor from city water flowing in a large amount, by using a specific felt-shaped fibrous active carbon for domestic water purifier as filter medium. CONSTITUTION:A fibrous active carbon consisting of the cellulose or regenerated cellulose featuring a specific surface area of no less than 1000m /g and a diameter of 5-30mu is made resistant to flame and activated. It is then shaped into the form of a felt having an apparent density of 0.07-0.25g/ml and thereafter immersed in a silver nitrate solution on which to deposite the silver of 0.2-5wt.%. The resulting felt-shaped active carbon fiber is filled directly in a water purifier, whereby the deodorizing effect for chlorine odor at a high speed of flowing water lasts longer and the disinfacting effect is also fully exerted.
