Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wipe for daily necessities, and more particularly to a cleaning tissue in which an additive to an impregnation liquid is improved to impart high cleanliness to an article surface.

[0002]

2. Description of the Related Art There has been a strong demand for cleanliness due to the improvement of family life in modern society, and a large number of cleaning products have been supplied accordingly. As one of them, wet tissue or wet wiper is a typical one,
Compared to conventional dry-type tissue paper, it is excellent in cleansing function and skin care properties, so it is popular and is used as a clean product and a medical product. What is called conventional wet tissue is a package that packs a flexible sheet that retains moisture and is basically only for the human body, such as cleaning the skin, wiping sweat, removing makeup, etc. It is used heavily for cleaning such as medical use. However, even if these wet tissues were used to wipe the surface of household goods or oily dust other than the human body, or the surface of wallpaper to which tobacco tar was strongly adhered, there was almost no cleaning effect.

As described above, various types of wet tissues which have been improved in daily life are widely used. For example, insect repellent tissues impregnated with a repellent for human body-associated harmful insects (JP-A-5-31694). A wet tissue impregnated with a glycol solvent containing a disinfectant and having excellent heat retention properties (JP-A-6-46968); a deodorant tissue impregnated with epigallocatechin gallard (utility model registration No. 3)
No. 040498) is known. As described above, various improvements have been made in wet tissues, although the heat retention, antibacterial properties, and deodorant properties are not sufficient.However, using a paper-like inexpensive wet-resistant material, Attention has not been paid to the removal of dust, oil, tobacco stains, etc. that have adhered to the surfaces of daily necessities.

On the other hand, chitosan, which is a deacetylated product of chitin, having a washing function is a general-purpose product. For example, Japanese Patent Application Laid-Open No. Sho 63-163 discloses a bath descaling agent containing chitosan or a modified product thereof as an active ingredient. No. 12699, Japanese Unexamined Patent Publication No. 63-162797, which is also a cleaning agent for an automatic washing machine, and Japanese Unexamined Patent Publication No. HEI 6 (1994), which discloses a cleaning composition excellent in foam feel and containing a modified chitosan together with an anionic or amphoteric surfactant.
Japanese Patent Publication No. 28759A is known. Further, as described in JP-A-62-138596, a solid soap excellent in usability obtained by blending water-insoluble chitin or chitosan with water-soluble chitin or chitosan is disclosed in JP-A-62-138596. It is also known to use together.

[0005]

As described above, conventional wet tissues are widely used as clean products and medical products, and there have been many proposals for improvements in the materials and functions of wet tissues. These compounds are added and blended to provide high antibacterial properties and the like, and their functions are being enhanced. However, the above-mentioned conventional wet wipers are generally used mainly for cleaning the human body, and there is no method for removing daily dust and oils on the surface of daily necessities around them, and is simple. The development of a solution for cleaning the surface of such daily products has been an issue in an economical and economical manner.

[0006]

SUMMARY OF THE INVENTION In view of the above problems, the present inventor has excellent power for cleaning or cleaning a surface, particularly for removing dirt such as machine oil, vegetable oil, dust, and cigarette sticking to the surface of an article. The present invention was finally created with the aim of realizing the economical provision of a simple wipe party exhibiting the above.

SUMMARY OF THE INVENTION The present invention is mainly intended for daily necessities, and is aimed at cleaning or cleaning dirt on the surface. The basic structure of the present invention is as follows (1) to (5).
It is shown in.

[0008] (1) A wipes for daily necessities in which a water-soluble chitin and / or chitosan is impregnated into a flexible sheet-like substrate capable of retaining moisture. (2) A wipe for daily necessities to which water-soluble chitin or chitosan is added at least 0.1 or more based on an aqueous component. (3) A wipe for daily necessities to which an alcohol solvent is further added as an additional component of the impregnating liquid. (4) A wipe for daily necessities further containing a bactericide as an additional component of the impregnating liquid. (5) Daily wipes using a moisture-resistant material such as paper, textile woven fabric, or fibrous non-woven fabric as a flexible sheet-like substrate.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.

[0010] The present invention relates to an unprecedented novel wipes for daily necessities, which mainly includes dust, vegetable oil,
It is an economical provision of wipes for cleaning or cleaning the surface of articles contaminated with machine oil or tobacco.

The wipes for daily necessities of the present invention are:
A package of flexible sheet-like substrates impregnated with an aqueous solution containing chitosan and / or chitin and other components, for cleaning dust and oils on the surface of daily necessities such as wood products, plastic products and metal products. It is extremely useful for use in In addition, both a package packed in a round case and a package packed in a rectangular portable simple package like a conventional wet tissue can be used.

In the present invention, the water-soluble chitin compounded in the aqueous solution for impregnating the flexible sheet-like substrate is a conventional commercially available product which is commonly used for improving the detergency.

Chitin is a kind of polysaccharide composed of amino sugars. It is composed of linear molecules in which D-glucosamine having an amino group acetylated is linked by β-1,4, and chitin itself is poorly soluble in water. Since there was almost no chemical reactivity and the foaming of the soap was reduced, the utility value was poor. The solubilization of chitin has been conventionally known (for example, JP-A-62-138596), and has been used for soaps and the like. On the other hand, chitosan is obtained by deacetylating chitin and has a water retention effect.
It is well known that conventionally, when added to soap, a softening effect is imparted to the skin and a moist and fresh feeling is obtained.

However, as described above, the use of chitosan or chitin as a detergent improving agent is described in the above-mentioned publications, but these can be used as an auxiliary solvent or in combination with a protein material. Use in the form of an aqueous solution of salt or salt, as in the present invention, by impregnating the wet tissue material alone to clean dust, oil, and tobacco stains that strongly adhere to the surface of daily necessities around them. Nothing was known to be effective in cleaning.

In the present invention, chitin, which has been water-soluble by means of glycolation, carboxymethylation, or sulfate esterification, is used for the first time for cleaning dust and oils on the surface of daily necessities such as wood products, plastic products, and metal products. Used for cleaning tissue. The daily necessities in the present invention include desks, furniture, home appliances, kitchen utensils, indoor building materials, and the like in which wood, plastic and metal are used abundantly.

In the present invention, the above-mentioned water-soluble chitin and / or chitosan is used as an aqueous solution for impregnating the material,
At least 0.1% by weight in total based on aqueous components
The water-soluble chitin and / or chitosan is impregnated into the wet-resistant material as an aqueous solution to provide a significant detergency due to a strong detergency. Furthermore, when water-soluble chitin and chitosan are used in combination, a synergistic effect is seen in the cleaning function for dirt such as oil, dust and tobacco tar, which is advantageously used.

The amount of water-soluble chitin or chitosan to be added to the aqueous solution is 0.1% in total based on the amount of the aqueous component.
It is preferable to add 〜3% by weight. If it is less than 0.1% by weight, its cleaning effect is poor, and if it exceeds 3% by weight, its cleaning effect hardly changes and there is no economic advantage.

By adding an alcohol solvent typified by a lower alcohol such as methanol or ethanol as an additional component to the aqueous solution containing the water-soluble chitin and / or chitosan, the cleaning effect can be further enhanced.

As the alcohol solvent used to further enhance the cleaning effect of the water-soluble chitin or chitosan, lower alcohols such as methanol and ethanol are used. Further, instead of the alcohol solvent, a glycol solvent such as propylene glycol, 1.3-butanediol, or isopropylene glycol can be used. The concentration of the aqueous solution of the alcohol solvent or the glycol solvent is preferably 3 to 20% by weight. If the content is 3% by weight or less, the cleaning effect is not obtained, and if the content is 10% by weight or more, the effect is flattened, so that the use effect is lost. A glycol solvent can be used instead of the alcohol solvent, but the cleaning effect in this case is almost the same as that of the alcohol solvent.

Further, a bactericidal property can be imparted by adding a bactericide as an appropriate additional component to the aqueous solution. The disinfectant used is an organic disinfectant such as benzalkonium chloride or paraben and an inorganic disinfectant such as silver zeolite, or silver zirconium phosphate or silver calcium phosphate can be used. About 0.01 to 0.1% by weight is used based on the amount of the components.

Further, the flexible wet-resistant material used in the present invention is paper, fibrous woven fabric or fibrous non-woven fabric.
As the fibers, natural fibers such as cotton and hemp, synthetic fibers such as rayon, and synthetic fibers such as polyamide can be used. However, paper or rayon nonwoven fabric which is excellent in wet performance in view of economy is a suitable material.

[0022]

According to the present invention, when water-soluble chitin and chitosan are added together, a synergistic effect can be seen on the washing function against oil stains. However, water-soluble chitin and / or chitosan can be removed from wet-resistant paper such as paper. By impregnating the material, due to their strong detergency, they have a remarkable effect of removing dirt from dust, oil, and tarnish, and can be further cleaned by adding an alcohol solvent, a glycol solvent, and the like. In addition, bactericidal properties are imparted by adding a bactericide.

As described above, the product of the present invention exhibits an unprecedented superior performance in removing oil and dust present on the surface of an article, and water-soluble chitin and chitosan have a water retention effect. By adding a bactericide, it is extremely useful as a wipe that is used for cleaning the surfaces of daily necessities around the body with bactericidal properties.
