Abstract

PROBLEM TO BE SOLVED: To obtain a cleaning wax having excellent light resistance, heat resistance, and safety and having a persisting antibacterial and/or deodorizing effect for a long time by dispersing a surfactant and an antibacterial or deodorizing metal/organic acid salt in a water-based emulsion wax. SOLUTION: At least one water-soluble salt of a metal having an antibacterial and/or deodorizing effect is added to an aqueous solution of an organic acid under agitation. The obtained solution is mixed with a surfactant to obtain a dispersion. This dispersion is added to a water-based emulsion wax under agitation. It is desirable for the sake of enhanced antibacterial power that the metal used is a combination of at least two members selected from among silver, copper, and zinc and it is desirable for the sake of enhanced deodorizing power that the metal is a combination of iron with manganese. It is usually desirable that the surfactant used is a combination of an anionic surfactant with a nonionic surfactant. The wax effectively applied is either of a natural wax and a synthetic wax.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aqueous wax composition which maintains antibacterial properties and deodorant properties and has detergency properties, such as flooring floors, chemical floors, walls, building materials, vehicles, electric products and the like. The present invention relates to an antibacterial deodorant cleaning wax capable of imparting antibacterial and deodorant functions to its surface by applying and spraying for various purposes.

[0002]

2. Description of the Related Art Conventionally, when an organic antibacterial agent is added to and mixed with a wax provided with antibacterial properties, it is generally toxic and has a serious problem in terms of safety. There were shortcomings in the long-lasting effect. As an example of adding and mixing an inorganic antibacterial agent, see JP-A-4-680.
No. 68, etc., but the inorganic antibacterial agent has a problem in miscibility, such as high specific gravity of itself, causing precipitation, and may be discolored by the influence of light or heat.

Japanese Patent Application Laid-Open No. Hei 9-137086 discloses a wax having antibacterial properties, which can prevent microorganisms, but cannot remove odorous components. Although there is an example using a filter medium (activated carbon, porous ceramic, etc.) or the like, the filter quickly becomes saturated and lacks sustainability of the effect.

[0004]

DISCLOSURE OF THE INVENTION The present invention provides a detersive wax having antibacterial properties excellent in light resistance, heat resistance, safety and sustainability thereof, and further having deodorant properties. With the goal.

[0005]

In order to achieve the above object, oxalic acid, malonic acid, maleic acid, succinic acid, aspartic acid, glutamic acid, butyric acid, lactic acid, glutaric acid, malic acid, benzoic acid and phthalic acid are required. The use of a small amount by adding a metal ion having an antibacterial and / or deodorizing effect to at least one or more solutions selected from organic acids such as fumaric acid, tartaric acid, citric acid, ethylenediaminetetraacetic acid and hexametaphosphoric acid It was found that antibacterial and / or deodorant properties were obtained and that discoloration was suppressed even after drying. Examples of metal ions having antibacterial properties and / or deodorant properties include silver, copper, zinc, iron, manganese, cobalt, nickel, tin, lead, titanium, zirconium, aluminum, and bismuth. The composition comprises oxalic acid, malonic acid, maleic acid, succinic acid, aspartic acid, glutamic acid, butyric acid, lactic acid, glutaric acid, malic acid, benzoic acid, phthalic acid, fumaric acid, tartaric acid, citric acid, ethylenediaminetetraacetic acid, hexametaline A solution-type antibacterial and / or deodorant can be obtained by adding one or more water-soluble metal salts of a metal having an antibacterial and / or deodorizing effect to a solution of an organic acid such as an acid or a mixture thereof and stirring the mixture. After mixing and dispersing this processing liquid with a surfactant, when added to an aqueous wax, there is no discoloration, and the antibacterial and / or deodorant effect lasts for a long time,
A washable wax which has excellent dispersibility and does not settle or solidify even when allowed to stand is obtained.

[0006] In order to achieve the above object, the surfactant used may be any of a cationic surfactant, an anionic surfactant, an amphoteric surfactant and a nonionic surfactant, or may be any of them. May be used, but a mixture of an anionic surfactant and a nonionic surfactant is generally desirable in order to increase the detergency. In order to enhance the antibacterial activity, a mixture of a cationic surfactant and an amphoteric surfactant is generally desirable.

[0007] In order to achieve the above object, it is desirable to select two or more of silver, copper and zinc from among metals to be used in order to enhance antibacterial activity, and the safety is high. In order to enhance the deodorizing power, a mixed solution of iron and manganese is desirable.

As a method of uniformly applying or coating, an aqueous dispersion of a compound of a metal and an organic acid having an antibacterial action and / or a deodorant action is used. By doing so, application or coating can be performed in a state close to the molecular level.

The antibacterial / deodorant cleaning component of the present invention is synthesized from natural waxes such as vegetable waxes, animal waxes, petroleum waxes, mineral waxes, etc., synthetic hydrocarbon waxes, modified waxes, hydrogenated waxes and the like. It is effectively applied to any wax such as wax.
