Description

TECHNICAL FIELD The present invention relates to a paper-rolling agent which is solid at room temperature and is used to moisten the fingertips when counting or rolling a large number of papers.

[Prior Art] When counting or rolling a large number of papers such as bills and telephone directories, it is usually necessary to moisten the fingertips with a sponge moistened with water in order to easily count or roll. There are many.

From this point of view, so-called paper turning agents, which are wetting agents exclusively for turning over paper, have been developed.

Japanese Examined Patent Publication No. 38-4959 proposes a method for producing a wet body for paper obtained by heating and dissolving stearic acid in glycerin, adding a caustic alkali solution to neutralize, and cooling and solidifying.

[Problems to be Solved by the Invention] However, the method proposed by Japanese Examined Patent Publication No. 38-4959 is good for gel formation because it uses so-called soap as a gel-forming substance. Since it has a slippery property, there is a problem in the turning effect, and it is not good as a paper-rolling agent. Also, it has a slimy feel to the fingers, which is not preferable in terms of usability.

In addition, glycerin oozes out on the surface to show a sweating state even if it is left for several hours, and there is a drawback that this sweat must be absorbed and wiped with a paper or the like. Further, with the passage of time, there is a problem that water and other volatile components fly away to cause volume contraction, and the hardness of the product changes. Therefore, there is a problem in terms of commercial value and turning effect. Therefore, paper turning is often done by using a sponge to moisten the fingertips, which was not enough in terms of popularization of this type of wetting agent. Therefore, it is necessary to frequently wet the fingertips with the sponge, and there are still many problems such as excessively watering the fingertips to stain the paper.

The object of the present invention is to reduce perspiration and volume contraction as long as it can be used for a long period of time, and to reduce the hardness change of the product, to provide excellent stability and safety of quality, and to use a so-called soap which is good in gel formation. Even if it does not slip, it has a good feeling in use and handling, and provides a solid paper-rolling agent having a remarkable paper-rolling effect.

[Means for Solving the Problems] As a result of earnestly studying the above problems, the present invention focused on improving the paper-rolling effect by first improving the gel-forming substance itself, and thus the fat having 8 to 36 carbon atoms. Alkali metal salt or ammonium salt of group carboxylic acid as a gel-forming substance,
In addition to using polyhydric alcohol as a moisturizing agent, a sequestering agent was added to the gel-forming substance in order to further reduce the slipping effect of the paper turning agent.

That is, by using a sequestering agent as a molder, it was found that the amount of so-called soap used was reduced, the gel-forming ability was not impaired, a remarkable paper-turning effect was exhibited, and there was no slimy feel on the fingers, The present invention has been completed.

The sequestering agent is ethylenediaminetetraacetic acid and its derivatives, and in the following abbreviations, EDTA4H, EDTA2Na, E
DTA4Na, EDTA3Na, HEDTA3Na, DTPA5Na, TTHA6Na, NTA3N
a, Special amine salt of EDTA, EDTA2NH ₄ , EDTA3NH ₄ , EDTA3
K, further organic acids, inorganic acids and derivatives thereof, specifically, gluconic acid, sodium gluconate, citric acid, sodium citrate, tartaric acid, sodium tartarate, pyrophosphate, sodium pyrophosphate, tripolyphosphate, tripolyphosphate Sodium salt, tetrametaphosphoric acid, tetrametaphosphoric acid sodium salt and the like can be mentioned, but the metal ion sealing agent is not limited to these.

The content of the sequestering agent is preferably 10% by weight at the maximum. If it exceeds 10% by weight, the effect of increasing the gel-forming ability is reduced, and the cohesive force of the gel is reduced,
The transfer of the component to the finger is reduced, and the effect of paper turning is reduced.

On the other hand, we believe that it is important to improve the moisturizing agent to directly achieve the improvement of the paper-turning effect. In order to retain or moisturize a large amount as much as possible, it has been found that it is preferable to use a water-absorbent polymer moisturizer instead of or together with the conventional polyhydric alcohol such as glycerin. Among them, the use of cross-linked polyacrylic acid and its derivatives as a moisturizing agent can reduce perspiration and volume shrinkage even in long-term use, as compared with the use of polyhydric alcohol alone, and the hardness change of the product is small and the quality of the product is small. It has been found that the stability and safety are excellent, the compatibility with soap is good, and the paper-rolling effect is remarkably improved. That is, cross-linked polyacrylic acid and its derivatives are substances originally proposed as diapers and cosmetics, but when used as a moisturizing agent for this type of paper-rolling agent, the paper-rolling agent is much more remarkable than expected. Be effective.

Crosslinked polyacrylic acid is obtained by polymerizing acrylic acid and a crosslinking agent in an organic solvent such as benzene. The crosslinking agent includes a monomer having two or more vinyl groups. Examples of the cross-linked polyacrylic acid derivative include cross-linked poly (acrylic acid-acrylic acid 2,3-
Dihydroxypropyl or 2-hydroxypropyl)
Is preferred. Cross-linked poly (acrylic acid-acrylic acid 2,
3-dihydroxypropyl or 2-hydroxypropyl) is a side chain carboxyl group of cross-linked polyacrylic acid.
It is obtained by esterification with 2,3-dihydroxypropyl or esterification with 2-hydroxypropyl. As a commercially available product, for example, "U-Jerry" (trade name) manufactured by Showa Denko KK can be used.

As the polyhydric alcohol, for example, glycerin, ethylene glycol and propylene glycol are desirable.

On the other hand, in the case of paper turning, the paper turning agent sometimes adheres to the fingertips and the paper, and it is extremely important for the paper turning agent to prevent the paper turning agent from being felt as a stain in use. Therefore, the present invention employs a means for making the paper turning agent transparent or translucent. That is, since the present paper turning agent uses soap as a gel-forming substance, it employs a constitution for adding a clearing agent to obtain a so-called transparent soap. Known transparent agents such as ethanol, glycerin, sucrose, and cyclohexanol can be appropriately used in order to obtain a transparent soap, but as a result of diligent study from the viewpoint of sufficiently ensuring moisturizing property, glucose,
Sugars such as sorbit are preferred.

In addition, since the paper turning agent is sometimes used for bills and the like, in order to prevent the paper turning agent from becoming a breeding source of microorganisms, and from the viewpoint of hygiene, the present invention contains a disinfectant. In particular, the disinfectant for natural fragrances is good in terms of feeling of use, and is suitable as a paper-rolling agent of this type. Examples of the natural flavor disinfectant include natural flavors containing terpenes such as cucumber oil such as eucalyptus oil and cypress oil, cassia oil, viment oil, bay oil and camphor oil. The content of the disinfectant of the natural fragrance is preferably up to 5% by weight. A small amount of preservative is also preferable.

[Operation] As described above, since the sequestering agent is added to the so-called soap as a shaping agent in the present invention, it is possible to reduce the amount of soap used without lowering the gel forming ability, and Sliding can be reduced. Therefore, the effect of turning over the paper is improved as compared with the conventional one, and there is no slimy feeling on the finger, and the usability is extremely good.

When cross-linked polyacrylic acid or its derivative is used as a humectant, volume shrinkage, which is a drawback of conventional paper-turning agents,
The sweating effect is remarkably improved. Moreover, since the moisturizing ability is remarkably superior to that of the conventional polyhydric alcohol alone, the paper-turning effect is remarkable. Up to 70% by weight is an effective range, especially 10-40% by weight of this type of moisturizer
It is preferable to contain it within the range.

Also, when sugars such as glucose and sorbit are blended as a clarifying agent, it is possible to prevent the adhered hands and rolled paper from being soiled without impairing the moisturizing property as a paper-rolling agent, improving the usefulness as a roll-up agent. To do. Furthermore, if a natural fragrance having a bactericidal property such as eucalyptus oil or cypress oil is added, it is possible to prevent the growth of microorganisms, which is hygienic. It is also nontoxic, highly safe, and stable in quality.

[Examples] Next, examples of the present invention will be described. Hereinafter, "parts" refers to parts by weight.

Example 1 While stirring 30 parts of sorbit and 40 parts of glycerin, 5 parts of stearic acid and 5 parts of EDTA2Na are added, and dissolved by heating at 80 ° C. 8.5% sodium hydroxide solution while continuing heating and stirring
Add 7.7 parts dropwise, stop stirring if pH is between 9 and 11,
Take out in a container and let it cool to solidify.

Example 2 10 parts of stearic acid was added to 30 parts of sorbit, 20 parts of glycerin, and 20 parts of U-jelly (trade name) manufactured by Showa Denko while stirring, and dissolved by heating at 80 ° C. Continue heating and stirring 8.
15.4 parts of 5% sodium hydroxide solution was added dropwise to adjust the pH to 9-11.
If it goes in between, stop stirring, take out in a container and let cool to solidify.

Example 3 Solbit 30 parts, Showa Denko U Jerry (trade name) 40
10 parts of stearic acid is added while stirring the parts, and dissolved by heating at 80 ° C. While continuing heating and stirring, 15.4 parts of 8.5% sodium hydroxide solution is added dropwise. If the pH is in the range of 9 to 11, stop stirring, take out to a container and allow to cool to solidify.

As a comparative example, the U-jelly of Example 2 was replaced with glycerin, and the preparation was performed under the same conditions.

Examples 4 to 5 5 parts of eucalyptus oil (Example 4) and 5 parts of hinoki oil (Example 5) were added as natural flavors to Example 2 to produce under the same conditions.

 Next, the test results are shown in Table-1 and Table-2.

In Example 1 in which EDTA2Na was added, an increase in the paper-turning effect by EDTA2Na can be confirmed.

In Examples 2 and 3 in which U-jelly was added, the number of sheets to be turned up was larger than that in Comparative Example in which U-jelly was not added, and it can be confirmed that the effect of turning up the paper by U-jelly is increased.

In addition, Examples 4 and 5 in which the natural fragrance was added, compared to Comparative Examples in which no natural fragrance was added, prevented the growth of microorganisms.

[Advantages of the Invention] Since the present invention has the above-mentioned constitution, by adding a sequestering agent, it is possible to reduce the amount of soap used without decreasing the gel strength and reduce the sliding effect. Therefore, it can contribute to the improvement of the paper-turning effect. Moreover, the feeling of sliminess on the fingers is eliminated and the feeling of use is good. Further, since cross-linked polyacrylic acid and its derivative are contained as a moisturizing agent, it is possible to improve the paper-rolling effect while reducing the volume shrinkage and the sweating action. In addition, the combination of natural fragrances has the effect of preventing the growth of microorganisms and cleaning the fingertips.

Therefore, the present invention has been able to provide a very useful paper-cutting agent that has never existed before.
