Description

  The present invention relates to cosmetics.

  Conventionally, moisturizing cosmetics for the purpose of moisturizing the skin and preventing the skin from drying are known (for example, Patent Documents 1 and 2). In these moisturizing cosmetics, the feeling of use (use feeling) at the time of application and after application is a very important characteristic. Specifically, in addition to the moisturizing feeling after application, which is an essential characteristic for a moisturizing cosmetic, the feeling of use mentioned above, for example, when applied, the moisturizing cosmetic feels like it quickly penetrates the skin and adjusts to the skin. Examples include a penetrating sensation, a feeling of massage at the time of application, no stickiness after application, and a rich feeling that can be felt when a dense agent is applied. In addition, as the texture of the skin after using the moisturizing cosmetic, various textures such as a soft texture, a firm texture, and a smooth texture are required.

  Each of the moisturizing cosmetics is designed so as to obtain a feeling of use and a texture of the skin after application according to the target user group. For example, users who have been using moisturizing cosmetics for a long period of time (especially female users) tend to demand high moisturizing feeling, and seek a feeling of massage at the time of application and a soft texture of the skin after application. There are cases. In addition, there is a case where elimination of fine wrinkles due to a strong tension is required.

  On the other hand, for example, users who are not experienced in using moisturizing cosmetics, male users, and the like may find skin familiarity, no stickiness, and smooth texture after application.

  An object of the present invention is to provide a cosmetic that is excellent in skin familiarity (penetration feeling) at the time of application of the cosmetic, has excellent moisturizing feeling on the skin after application of the cosmetic, and can provide a smooth texture without stickiness. It is. Smooth texture refers to a smooth feel that does not feel rough irregularities on the skin surface. Moreover, skin familiarity (penetration feeling) refers to the feeling that cosmetics and skin quickly become compatible at the time of application.

The present invention contains the following component A, component B including component B1, and component C, the mass ratio of component B to component A (component B / component A) is 50 to 250, and component B1 relative to component B It is related with cosmetics whose mass ratio (component B1 / component B) is 0.2-1.0.
Component A: Pullulan Component B: Polyhydric alcohol containing Component B1 Component B1: 1,3-propanediol Component C: Water

  Since the cosmetic of the present invention has the above-described configuration, it is excellent in skin familiarity (penetration feeling) when the cosmetic is applied to the skin. Moreover, there is no stickiness of the skin after the application of the cosmetic, and it can impart an excellent moisturizing feeling and smooth texture to the skin after the application.

  Component B is “polyhydric alcohol containing component B1”, and component B1 is “1,3-propanediol”. By blending component B, the moisturizing feeling can be improved. Moreover, in this invention, when component B contains component B1 in a specific ratio, the skin familiarity at the time of application | coating of the cosmetics of this invention becomes favorable, and a penetrating feeling improves. Furthermore, since component B1 has little stickiness, it contributes to reduction of stickiness.

  Component B2 is “a trihydric or higher polyhydric alcohol”. Component B2 is particularly excellent in the moisturizing feeling improving effect. Component B2 includes polyethylene glycol (PEG), glycerin, diglycerin, triglycerin, sugar alcohol (eg, maltitol, mannitol, sorbitol, etc.). Among these, sugar alcohols are preferable from the viewpoint that stickiness is particularly small. The sugar alcohol is not particularly limited, but maltitol is preferable because it has a particularly good skin fit, and sorbitol is preferable because it has a particularly excellent moisturizing feeling.

  Component B3 is “polyoxyalkylene alkyl glucoside”. In addition to the moisturizing feeling improving effect, the component B3 is also excellent in the skin familiarity improving effect. Examples of the oxyalkylene group in Component B3 include an oxyethylene group and an oxypropylene group.
