Description

  The present invention relates to a skin cleanser composition, and more particularly to a skin cleanser composition having excellent sensory characteristics such as a moist feeling when washed off and a moist feeling after towel drying.

  Conventionally, moisturizers are blended in various cosmetics for the purpose of maintaining the homeostasis function of the skin and protecting the skin from drying in the winter. Recently, moisturizers with high palatability that provide moist feeling and comfort to the user have been developed. Therefore, when selecting a moisturizing agent to be blended in cosmetics, it is currently performed to select a moisturizing agent that has both a moisturizing effect and high palatability. For example, polyhydric alcohols and water-soluble polymers are often used as materials that have high palatability and improve the sensory characteristics by making them feel moist.

  As those using these moisturizers for cleaning cosmetics, a skin cleansing composition containing a polyhydric alcohol with respect to fatty acid soap (for example, see Patent Document 1) or a skin cleansing composition containing a water-soluble polymer. (For example, refer to Patent Document 2).

  However, although the washing cosmetics containing these moisturizing agents are excellent in the sensory aspect such as moist feeling at the time of washing, they are not sufficiently satisfactory in the sensory aspect such as moist feeling after towel drying.

  On the other hand, l-menthyl glyceryl ether is known not only as a fragrance that gives a refreshing feeling, but also as a component having a cooling sensation effect. 3), and a composition for rising hot water blended as a cooling sensation agent (for example, see Patent Document 4).

  As described above, polyhydric alcohols and water-soluble polymers blended in conventional skin cleansing agents have some effect, but many have a moist feeling when washed off, and are not necessarily preferable in terms of sensory characteristics after towel drying. It was not a thing. Accordingly, there has been a demand for the development of a new composition that also improves the sensory characteristics after towel drying to be blended in the skin cleanser.

  That is, an object of the present invention is to provide a skin cleanser composition having excellent sensory characteristics in both moist feeling when washed off and moist feeling after towel drying.

  As a result of diligent research in view of such circumstances, the present inventors have combined 1-menthyl glyceryl ether, which has been known as a cooling sensation agent, with a specific fatty acid, so that not only during washing but also sensory characteristics after towel drying. The present invention has been completed by finding that it can be applied to a wide range of preparations.

  That is, the present invention is a skin cleanser composition comprising a fatty acid basic amino acid salt and l-menthyl glyceryl ether.

  The fatty acid basic amino acid salt is preferably a fatty acid arginine salt.

  ADVANTAGE OF THE INVENTION According to this invention, the skin cleansing composition excellent in sensory surfaces, such as not only at the time of washing | cleaning but also a moist feeling after towel drying, can be provided.

  Hereinafter, embodiments of the present invention will be described in detail.

The basic amino acid salt portion is selected from arginine, lysine, and histidine, and arginine is preferable from the viewpoint of achieving a particularly moist feeling and stability after towel drying.

  The blending amount of the fatty acid basic amino acid salt (A) is preferably 0.01 to 30% by mass, more preferably 0.05 to 20% by mass, and more preferably 0.1% in the total mass of the skin cleansing composition. 10 mass% is suitable at the point of foaming, foam quality, prevention of the stickiness at the time of a rinse, a moist feeling after towel drying, and stability.

  Next, (B) 1-menthyl glyceryl ether according to the present invention may be one generally extracted from mint or peppermint by a conventional method.

  EXAMPLES Next, although an Example demonstrates this invention in detail, this invention is not limited to these Examples.

Example 1, Comparative Examples 1 and 2 (skin cleanser composition)
Based on the formulation shown in Table 1, the skin cleanser compositions of Example 1 and Comparative Examples 1 and 2 were prepared according to a conventional method, and moist feeling after washing (sensory evaluation) by the method shown below, moist after towel drying An evaluation test of feeling (sensory evaluation) and the rate of decrease in skin moisture after towel drying was performed. The test results are also shown in Table 1. In addition, all compounding quantities are the mass% (the following is the same).

・ Evaluation of moist feeling at the time of washing and after towel drying Panel (9 persons) actually uses each of the skin cleansing compositions shown in Examples and Comparative Examples in the bathroom at home, and moistening after washing and after towel drying The feeling was evaluated.
<Sensory evaluation>
Evaluation was carried out by a sensory test by nine specialist panels.
A: All nine responded that they were moist and excellent.
○: All 6-8 responded that they were moist and excellent.
Δ: All 3 to 5 people answered that they were moist and excellent.
X: All 0 to 2 people answered that they were moist and excellent.

・ Evaluation of skin moisture content reduction rate after towel drying Each skin cleansing composition shown in Example 1 and Comparative Examples 1 and 2 was actually used using both arms of the panel (3 persons). The amount of decrease in skin moisture in both arms was measured and evaluated using a CUTERTER MPA580. The numerical values in Table 1 are percentage values of the amount of water loss measured using both arms of the panel, and are values obtained by calculation when the skin water amount reduction amount of Comparative Example 1 is taken as 100.

  As is apparent from Table 1, it can be seen that the Examples are superior to the Comparative Examples in sensory evaluation of moist feeling at the time of washing and after towel drying, and the rate of decrease in skin moisture after towel drying is small.
