DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic which has a fresh and moist feeling and, in particular, when a flavor is blended, a cosmetic which improves the unpleasant taste of raw materials and flavor when used. To provide.

[0002]

2. Description of the Related Art Conventionally, various types of cosmetics have been studied in order to give the skin a moist feeling. Various studies have been made on the eyes and lips, which are particularly sensitive to dryness, in order to prevent the dryness and maintain moisture. Since these cosmetics mainly contain an oily component, a moist feeling can be obtained, but a fresh feeling of use cannot be obtained. Also,
Lip cosmetics, such as fragrances, have the drawback of feeling unpleasant tastes of raw materials and fragrances themselves when used.

[0003]

As a technique for blending a large amount of water to obtain a fresh feeling of use, a technique of blending water with an oily makeup cosmetic using a paste-like silicone composition (Japanese Patent Laid-Open Publication No. However, there is a drawback that when a large amount of oil is blended, the oily feeling is produced and the feeling of use is deteriorated. Further, lip cosmetics and the like are applied to the lips, and their odor and taste may be mixed into the mouth at the time of use, which may cause discomfort to the user. Therefore, a technique of using a sweetener or a technique of improving the smell or taste by using a specific flavor (Japanese Patent Laid-Open No. 9-2)
08429), but the effect was not yet satisfactory. Therefore, there has been a demand for the development of cosmetics in which the taste and odor of raw materials and fragrances are reduced.

[0004]

Under such circumstances, the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result,
The inventor has found that by blending a specific component in a cosmetic, a cosmetic excellent in reducing the taste of raw materials and flavors can be obtained, and completed the present invention.

That is, the present invention provides the following components (A) to
(C) A cosmetic comprising (A) a partially crosslinked polyether-modified organopolysiloxane polymer, (B) a sweetener, and (C) an aqueous component.
