2. Description of the Related Art In recent years, there has been an interest in making nails beautiful not only from a hygienic viewpoint but also from a cosmetic viewpoint. However, stains such as yellowing of nails are difficult to remove with ordinary solid or liquid soap and the like, and development of a nail-specific cleaning agent, so-called nail bleach, is desired.

Conventionally, as a nail-specific cleaning agent, a tablet-type cleaning agent which uses an anionic surfactant as a cleaning component and is dissolved in water or hot water has been known, and further has a solubility in water or hot water. There is also known a tablet type compounded with an organic acid and a carbonate which foam by an acid-base reaction in order to promote it.
However, they do not have sufficient washing action for yellowing of nails and the like, and improvement thereof is desired. In addition, if the cleaning effect is strengthened so that the nail surface is sufficiently cleaned, the skin of the fingers becomes rough, and a healthy beauty full of blood circulation cannot be maintained.
The fact is that it does not promote blood circulation in the nail bed and bring out the natural beauty of the nail.

An agent was prepared.

Immediately after the obtained detergent was put into 200 ml of lukewarm water, nails and fingers were put in and kept in that state for 2 minutes for washing. This washing was performed by a panel of 50 persons, and changes in nails and fingertips before and after washing and during washing were evaluated. Table 1 shows the results.

Examples 2 and 3 and Comparative Examples 1 to 3 Tablets were prepared in the same manner as in Example 1 using the materials having the compositions shown in Table 1. Ten tablets thus obtained were packaged in the same manner as in Example 1 with sugar containing high-pressure gas, thereby preparing a finger and nail cleaner. However, in Comparative Example 3, 10 tablets were used as a finger and nail cleaning agent without using a saccharide containing high-pressure gas. The same evaluation as in Example 1 was performed for each of the obtained cleaning agents. Table 1 shows the results.

[0025]

[Table 1]

From the results shown in Table 1, the nails did not turn white in Comparative Example 1 in which no reducing agent was added. Further, in Comparative Example 2 in which foaming due to an acid-base reaction was not involved without adding a carbonate, the effect of a reducing agent or the like was insufficient, and a few panels evaluated that the nails became white or the nails and fingertips were removed. Was. In addition, despite the fact that the saccharide containing the high-pressure gas was blended in the same manner as in the examples, the number of panels evaluated to have moisturized nails and fingertips was smaller than in the examples. Further, in Comparative Example 3 in which the saccharide containing the high-pressure gas was not mixed, the panel evaluated that there was no irritation of the fingertip, the cleaning effect by the reducing agent was inferior to that of the example, and the fingertip was moisturized. It decreased to about half.
