Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a novel cleaning agent that can easily remove dirt from hands and feet without using water.

[Prior Art] Conventionally, so-called soaps have been used to remove dirt from hands, feet, etc. The action of these soaps was to treat hydrophobic dirt such as oil with a surfactant to make it solubilized in water and wash it away with water. Therefore, water is always required to remove stains from soap, and using soap on stones in the absence of water will have no effect at all, and will actually increase the stains caused by the soap itself.

On the other hand, in our daily lives, we want to remove dirt from our hands and feet, but
Very often this is not possible due to lack of water. For example, when you are engaged in mechanical work, car repair, tire replacement, mountain climbing, camping, farming, etc., you may not be able to wash your clothes because there is no water nearby. Wiping with paper, cloth, etc. is generally practiced.However, this method cannot sufficiently remove oily stains, nor can it be expected to sterilize or remove odors. The inventors of the present invention have conducted intensive studies on methods for removing stains in which water cannot be easily used, and have completed the following invention.

[Problems to be Solved by the Invention] An object of the present invention is to provide a cleaning agent that can easily clean dirt from hands and feet even when water is not easily available.

[Means for solving the problem] The means of the present invention is to apply a polymer solution to the soiled area,
Dirt is removed by attaching dirt to a thin polymer film formed by evaporating and evaporating a solvent, and then removing the film.

[Effect] With this method of removing dirt, dirt can be completely removed without using water by rubbing the thin polymer film that forms on the dirt area with your hands or wiping it with paper. . It also has a bactericidal effect and odor removal effect, so you can get the same cleaning effect as soap without using water.

BACKGROUND ART Conventionally, there has been a method of forming a polymer film on the facial skin as a so-called cosmetic pack and using it as a cosmetic. In this case, the purpose of use is not to remove dirt, but rather to stimulate and improve blood circulation by pulling the skin with the polymer, and to prevent skin roughness and rejuvenate the skin with added blood circulation promoters and skin moisturizers. In many cases, it is used for the purpose of removing small amounts of dirt from pores as an accompanying dirt-removing effect.

On the other hand, the purpose of the hand and foot cleansing agent according to the present invention is significantly different from that of conventional cosmetic packs. It is used simply as a cleansing agent and does not have any effect as a cosmetic. Also, the drying time of the applied polymer solution is 10 to 30 minutes in the case of a cosmetic pack.
The drying time of the cleaning agent according to the present invention is designed to take several tens of seconds. As described above, the hand and foot cleanser of the present invention was created with a completely different purpose and concept from those of conventional facial makeup packs.

The solvent for the polymer solution used is desirably one that can easily evaporate and volatilize at room temperature and atmospheric pressure, is mild to the skin, and has no off-odor. Any solvent may be used as long as it meets these requirements, but a mixed solution of alcohol and water is particularly preferred. The concentration of polyvinyl alcohol, which is a polymer, may be such that it can form a film and has a viscosity that allows it to be spread thinly.The optimum concentration varies depending on the molecular weight of the polymer, but is preferably in the range of 15 to 35%.

Further, the molecular weight of the polymer can range from oligomers with a molecular weight of about 1,000 to polymers with a high molecular weight of 1,000,000 or more.

In the case of high molecular weight polymers, it is easier to use if the polymer concentration is lowered.

When these polymers are difficult to melt, they can be stabilized by using an emulsifier. The type of emulsifier used can be selected optimally depending on the amount of polymer and solvent.
Although the type is not particularly limited, polyoxine ethylene emulsifiers, sorbitan emulsifiers, alkyl sulfate emulsifiers, and the like are preferred. In addition, glycerin or methyl p-oxybenzoate as a flavor preservative may be added to protect the skin if necessary.

Methods for applying the polymer solution include spreading it thinly by hand, spreading it with a brush, etc., and spraying, and any method that can be applied thinly may be used. There are no particular regulations regarding the coating method.

[Example] Example-1 Limbs composed of 25.5% polyvinyl alcohol, 2.5% furopylene gellicol, 9.0% ethanol, 1.0% polyoxyethylene sorbitan monolaurate, and 62% water. The cleaning agent was applied to oily hands after car repair. The amount applied was about 5 g per hand. The application method was to spread it thinly by hand. After leaving it for about 30 seconds, a thin polymer film was formed, and this polymer film was removed by rubbing both hands together vigorously. As long as the polymer coating was removed sufficiently, the oil on my hands was removed very well, and the oily odor was also removed.

Example 2 A polymer solution having the composition of Example 1 was applied to hands soiled with soil from field work. When the polymer coating was applied and removed in the same manner as in Example 1, my hands, which had been stained black with dirt, became very clean.

On the other hand, in order to confirm the sterilization and removal effects, hands soiled with soil before applying the polymer solution and hands after removing the applied film were each pressed onto the surface of a normal agar medium that had been solidified on a Petri dish and left at 37°C for 24 hours. However, when the normal agar medium was then taken out, numerous colonies were detected on the medium where the hand was pressed before the polymer solution was applied, but on the medium where the hand was pressed after the polymer solution was applied and the film was removed, only one colony per hand was detected. Only 12 colonies were detected. In this way, it has been found that this cleaning agent has not only dirt removal effects but also sterilization and sterilization effects.

Example 3 A cleaning agent having the same composition as in Example 1 was used for the purpose of removing the fishy odor caused by coming into contact with fish while fishing.

The amount used was 8g per hand. The coating method was to scoop it out with a brush and spread the tnibolymer solution on it. When the polymer film was removed approximately 1 minute after application, the fishy odor was successfully removed. As mentioned in Part B, even in places where water is available and soap can be used, the present invention is easier to operate than using soap, and can produce effects equal to or greater than when using soap.

[Effects of the Invention] According to the present invention, it is possible to easily remove dirt from hands and feet even in places where water cannot be easily used, and at the same time, it is possible to sterilize and remove dirt from hands and feet.
It can also exhibit sterilizing and deodorizing effects.
