TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a skin wiping composition diluted with water or hot water in a basin or the like. More specifically, the present invention relates to a wiping composition having sufficient detergency, non-greasy skin after use, sufficient moisture in the skin, prevention of rough skin, less re-contamination, and excellent stability over time.
[0002]
[Prior art]
In order for a person to live, it is necessary to regularly wipe off dirt from the outside and dirt from secretions such as sebum and sweat. In general, dirt is removed by using a solid or liquid soap or the like and washing it by itself when taking a bath. However, since it is difficult for a baby or a person with a physical disability, it is necessary for a caregiver to clean the body by using a wet towel or the like to wipe off dirt. The chemical used to clean the body in such a case is called a "wiping agent" and is generally diluted with warm water using a washbasin or the like, or diluted. Use directly without using.
[0003]
Since the type of wiper used after dilution is usually diluted about 10 to 1000 times with hot water, the amount of the active ingredient in the formulation is reduced, and the cleansing property and the moisturizing property after use are reduced. This is disadvantageous in comparison with the type used without dilution. However, the diluting type cleaning agent can be expected to have a bathing effect (for example, a refreshing feeling, a refreshing feeling, and a feeling of warmth) by hot water, so that it is comfortable even for a care recipient. In addition, since the amount of medicine used at one time is small, it is felt that the cost merit is high for consumers. Therefore, it is a type generally used in nursing care for the elderly, wiping a baby, and the like.
[0004]
In particular, in recent years, with the aging society, the demand for cleaning agents has been rapidly increasing, and the development of more functional and superior cleaning agents has been desired. Until now, the wiping agents containing dimethylpolysiloxane or polyether-modified silicone as a main component described in JP-A-64-38018 and JP-A-64-79108 have been developed. Is not sufficient, and sufficient skin and moisture cannot be given to the skin after use. Furthermore, it has the effect of imparting sufficient barrier properties to the skin after use to prevent skin roughness, and in particular, preventing re-contamination where dirt such as dirt is transferred from a towel when wiping another part (re-wiping). I haven't.
[0005]
[Problems to be solved by the invention]
Solution to Problem The present invention solves the above problems, and provides a cleaning agent of a type that is used after dilution, has sufficient detergency, does not stick to the skin after use, maintains sufficient moisture and moisture, prevents rough skin, and re-wiping.

X: Bad and sticky (average value less than 1.5 points).
[0044]
(3) Peeling and Moistening after Use 13 women (32 to 45 years old) and 7 men (33 to 44 years old) were panelists. The entire body was wiped with a cotton towel impregnated with the detergent composition in the same manner as in (2) above, and the moisture of the skin after 15 minutes was scored as follows.
[0045]
2 points: If the skin has moisture and moisture, and you feel that it is healthy skin 1 point: If you feel that the skin is slightly bulky and there is little or no moisture, or 0 points if you feel that there is no moisture If you feel that there is no moisture or no beam.
[0046]
The average value of 20 persons was determined, and the skin scalp and moisture after use were evaluated according to the following criteria.

The state was rated as follows.
[0048]
2 points: When the skin is not felt at all 1 point: When the skin is slightly roughened 0 points: When the skin is felt rough.
[0049]
The average value of 10 persons was obtained, and the effect of preventing skin roughness was evaluated according to the following criteria.
：: Good skin roughness prevention effect (average value of 1.5 points or more)
×: Poor skin roughness prevention effect (average value less than 1.5 points).
[0050]
(5) Stability over time The wiping composition was sealed in a transparent glass container and stored at 5 ° C., 25 ° C., and 40 ° C. for 3 months, and its appearance was observed and evaluated according to the following three grades.

[0052]
(Examples 1 to 7)
A wiping composition containing each component at the ratio shown in Table 1 was prepared and evaluated by the above method. Details of each component in Table 1 are separately shown in Table 2. Table 4 shows the results.
[0053]
[Table 1]

[0054]
[Table 2]

[0057]
[Table 4]

[0058]
As is clear from the results shown in Table 4, the wiping compositions of the present invention of Examples 1 to 7 all have sufficient detergency, do not stick to the skin after use, and retain sufficient abrasion and moisture. At the same time, rough skin was prevented, re-contamination was difficult, and stability with time was excellent.
[0059]
On the other hand, with the wiping compositions of Comparative Examples 1 to 7, sufficient performance was not obtained. Specifically, the composition of Comparative Example 1 contains a silicone derivative (a) ′ different from the component (a) of the present invention instead of the component (a), so that the cleaning rate is deteriorated and the composition is stable with time. The sex was getting worse. In Comparative Example 2, since the content of the component (b) was small, the cleaning property was deteriorated, and the effect of preventing rough skin was weakened. In Comparative Example 3, since the content of the component (b) was too large, a sticky feeling remained after use, the moisture and moisture were lost, and the stability over time was poor. In Comparative Example 4, since the component (c) was not contained, no moisture was obtained after use and the stability with time was poor. In Comparative Example 5, since the component (d) was not contained, the moisture and moisture after use disappeared, and the effect of preventing rough skin was weakened. In Comparative Examples 6 and 7, since the component (e) was not contained, skin scalp and moisture disappeared after use, and the effect of preventing skin roughness was weakened. As described above, it is understood that the use of the wiping composition of the present invention containing the predetermined components (a) to (e) at a predetermined ratio provides an excellent cleaning effect and a feeling of use.
