[Action] Saponin is a general term for glycosides that use polycyclic compounds as aglycones, and includes plant-derived substances such as asparagus, soybeans, adzuki beans, ginseng, and hechima, and humans and yamamako. It is known that it is of animal origin. Further, saponin is generally less toxic even orally, and it is known that it has a surface active action, a hemolytic action, a fish toxic action, an insecticidal action, a foaming action and a bactericidal action. In addition, saponin is easily soluble in water and the solution has no slimy or sticky feeling.

That is, the present inventors have added a saponin having the above-mentioned properties to a detergent composition to provide excellent cleaning action, bactericidal action and foaming property, high safety and no discomfort. They found that a drug could be obtained.

As described above, the saponin-containing detergent has no discomfort such as sliminess or stickiness, and has extremely low toxicity to the human body. Therefore, it is suitable for use in wet wipes and clean cotton that are not washed off with water after use. Can be included. In addition, by including the saponin in the wet wipers and the clean cotton as described above, a high cleaning effect can be obtained. Furthermore, since saponin does not deteriorate papers, non-woven fabrics, cotton, cloth and the like, it can be contained in a wide variety of hygiene products.

Hereinafter, the present invention will be described in more detail with reference to examples. However, the scope of the present invention is not limited by the following examples.

[0012]

Example 1 In this example, the detergency of soybean saponins and asparagus saponins (washing test) was measured.
The cleaning power was measured by partially changing JIS k-3362 “Test method for synthetic detergent, Evaluation method for cleaning power of synthetic detergent for kitchen”.

First, three glass plates 4 were prepared for each sample, and the weight of each glass plate 4 was measured. On the other hand, 20 g of triolein, 10 g of squalene, 10 g of cholesterol and 10 g of palmitic acid were placed in a conical beaker, 50 ml of chloroform was put therein and heated at 45 ° C. to be dissolved, and the obtained solution was used as a model soil solution. The model stain solution was prepared by simulating the oil content of human skin. Therefore, the composition of the model soil solution is not particularly limited to the above composition, and there is no problem even if other components are added or the above components are removed.

Next, the glass plate 4 whose weight was measured was placed in the conical beaker and allowed to stand for about 1 minute to stain the glass plate 4. After the dirt was attached, the glass plate 4 was gently pulled up and air-dried for about 1 hour, and the weight of the glass plate 4 was measured to calculate the weight of the adhered dirt.

On the other hand, the pH was adjusted to 9 with sodium carbonate.
0.01, 0.05, 0.1 and 0.5% (w / v) Soy Saponin Aqueous Solution, 0.005, 0.01, 0.1 and 0.5% (w / v) Asparagus Saponin Aqueous Solution, and Comparative Cleaning Solution (traditional detergent without saponin) , And an aqueous solution containing a natural surfactant, which has been widely used from the past, were prepared as 900 ml, and used as a sample solution 7. The soybean saponins and asparagus saponins are pulverized raw materials containing each saponin, degreased with a non-polar solvent such as n-hexane, extracted with a hydrous lower alcohol, filtered and concentrated, and then n- Extraction and purification were carried out by a method such as partitioning with butanol and water to desugar, concentrating and drying n-butanol, and then drying (from Japanese Patent Application Laid-Open No. 2-129198 “Asparagus waste). Disclosed in JP-A-2-247196, "Method for recovering purified saponin from asparagus", or Japanese Patent Application No. 2-412328, "Method for producing saponin from soybean hypocotyl". In addition, the concentration of the saponin-containing aqueous solution (sample solution 7) should be 0.005-1.
Although set to 0% (w / v), these numerical values do not limit the scope of the present invention.

The sample solution 7 prepared above and the magnetic stirrer 5 were placed in a beaker 6, and the beaker 6
Is placed in an incubator 3 placed on a mag mixer 2, and three glass plates 4 fixed to the cylindrical holder 1 to which the above-mentioned stains are attached are immersed in a sample solution 7, and the solution 7 is placed at 40 ° C. The mixture was stirred at 350 rpm for 30 minutes (Fig. 1).

After stirring, three glass plates 4 (1 sample) were rinsed with about 500 ml of ion-exchanged water and left overnight in a desiccator to dry. After drying, the weight of the glass plate 4 was measured to calculate the weight of the remaining stains, and the detergency was evaluated (the stain removal rate was calculated using the formula shown in Chemical formula 1). The results are shown in Table 1. Indicated.

[0018]

[Table 1]

As can be seen from Table 1, the aqueous solutions of soybean saponin and asparagus saponin showed detergency equal to or higher than that of conventional detergents and natural surfactants.

[0020]

Example 2 0.1% adjusted to pH 7 with sodium carbonate
(w / v) asparagus saponin aqueous solution, soybean saponin aqueous solution, and mixed solution of asparagus saponin and soybean saponin (0.01% of asparagus saponin, 0.9% of soybean saponin) were prepared in 900 ml, respectively Was subjected to a cleaning test and its evaluation in the same manner as in Example 1, and the results are shown in Table 2.

[0021]

[Table 2]

As can be seen from Table 2, the solutions in which asparagus saponin and soybean saponin were mixed showed higher detergency than the solutions alone. That is, when two or more kinds of saponins are mixed in an appropriate amount, a higher detergency than that used alone may be obtained.

[0023]

Example 3 An example of the clean cotton of the present invention is shown below.

First, asparagus saponin 0.1% (w /
v), chlorhexidine gluconate 0.02% (w / v), and purified water 10 ml were mixed. Then, about 1.6 g of the mixed solution
The absorbent cotton was soaked in the absorbent cotton, sealed, and then subjected to high-pressure steam sterilization treatment to produce clean cotton.

The clean cotton produced as described above showed a high cleaning effect and had no sticky feeling or slimy feeling after use. In addition to the above components, preservatives such as benzoic acid, moisturizers, cleaning aids, deodorants, fragrances, lower alcohols such as ethanol, buffer agents, chelating agents, anti-inflammatory agents, surfactants other than the indicated saponin, etc. are compounded. You can also do it.

[0026]

[Example 4] The clean cotton (clean cotton 1) prepared in Example 3 and soybean saponin instead of asparagus saponin
Clean cotton produced in the same manner as in Example 3 except that 0.1% (w / v) was blended (clean cotton 2), and a minimum of 3
For 15 hours, a detergency test was conducted on 15 testers who did not wash their faces. In the detergency test, the cheeks as test sites were wiped three times with the above-mentioned clean cotton, and then the ability to remove sebum was determined, and the results are shown in Table 3. In addition, a clean cotton obtained by removing only saponin from the above clean cotton was also prepared, and the clean cotton was used as a control.

[0027]

[Table 3]

As can be seen from Table 3, the clean cotton of the present invention was excellent in the ability to remove sebum.

[0029]

[Embodiment 5] An example of the wet wipes (wet tissue) of the present invention is shown below.

Soybean saponin 0.1% (w / v), paraben 0.2
% (W / v) and purified water were mixed and soaked in a 4C cloth (trade name) dry non-woven fabric to prepare a wet tissue containing a detergent. The wet tissue thus produced exhibited a high cleaning effect and had no sticky feeling or slimy feeling after use.

[0031]

EFFECTS OF THE INVENTION The body cleaning agent of the present invention eliminates the slimy feeling, sticky feeling and irritation characteristic of conventional cleaning agents. Further, since the personal cleansing agent of the present invention shows a high detergency at a low concentration and has high safety, it has become possible to impregnate wet wipes and clean cotton which are not washed with water. Therefore, the cleaning effect of wet wipes and clean cotton was remarkably improved.
