Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is excellent in the moisturizing effect on skin and the effect of improving bulkiness, and is non-greasy after bathing.
The present invention relates to a bath agent composition that provides a moist feel.

[0002]

2. Description of the Related Art Bathing has various effects such as cleansing the body, warming not only limbs but also the core, and relaxing mentally, and is an essential activity in daily life. On the other hand, many people complain of the loss of oil content from the skin due to bathing, especially the bulkiness of the skin after bathing in the winter. In addition, such people usually use various skin care products such as lotions and creams after bathing in order to suppress the bulkiness of the skin after bathing. However, when using a skin care product, labor is required for its application and the like, and it is difficult for an elderly person to apply the skin care product to every corner of the body. Therefore, there is an attempt to prevent the loss of oil from the skin by blending a bath agent with an oil or a moisturizer.

[0003]

However, when a bath agent containing an oily component such as oil is used, the skin care effect is insufficient or the addition of the oily component is sufficient. When a bath additive with an added amount is used, there is a problem in that the oily component remains unnecessarily on the skin after bathing, resulting in a particular sticky feeling. Therefore, there has been a demand for a bath preparation which is excellent in the moisturizing effect on the skin and the effect of improving the bulkiness, and which is not sticky to the skin after bathing.

[0004]

[Means for Solving the Problems] In view of such circumstances, the present inventors have conducted diligent research, and as a result, rice germ oil and a bath agent containing a synthetic di-fatty acid glycerin ester and / or a synthetic tri-fatty acid glycerin ester were blended. However, the present invention has been completed, and it was found that it has an excellent effect of protecting the skin and an effect of improving bulkiness, has no stickiness after bathing, and brings a moist feel.

That is, the present invention provides a bath agent composition containing one or more selected from synthetic di-fatty acid glycerin ester and synthetic tri-fatty acid glycerin ester, and rice germ oil.
