Description

  The present invention relates to a cosmetic.

In the past, in skin care cosmetics, application of polyols such as glycerin, water-soluble polymers such as Carbopol, etc. has been studied in order to improve the spread and moist feeling at the time of application. On the other hand, when a polyol or a water-soluble polymer is blended, the skin after application is tacky during application, and the skin care cosmetic is stretched too much, and it feels slippery (even if it continues to extend on the skin) Cosmetics remained, fingers slipped and felt slimy, and there was a lack of feeling to penetrate the skin. In order to improve such stickiness and upper slip, it has been considered to blend a silicone elastomer.
For example, Patent Document 1 describes a skin external preparation containing silicone elastomer powder, glycerin, acyl glutamate, hydrocarbon oil, carboxyvinyl polymer and / or alkyl-modified carboxyvinyl polymer, and Patent Document 2 discloses silicone. Cosmetics containing powder dispersions, moisturizers, water-soluble polymers are described.

However, even with these conventional cosmetics, although the stickiness of the skin after application can be improved, the upper slip at the time of application can not be sufficiently improved. In addition, in the part where the fingertip and the skin touch, it seems to be caused by silicone elastomer, but feels resistance feeling like squeeze, and can not be applied smoothly even though the cosmetic remains on the skin was there. Furthermore, since the cosmetic remains on the skin during application and is seen as shine, there is a problem that the cosmetic lacks a feeling of being familiar with the skin and it is difficult to feel the effect of applying the cosmetic.
Therefore, there is a need for a cosmetic which has no upper slip at the time of application, does not feel squeaky at the fingertip touching the skin, and can not be seen as shine on the skin.
TECHNICAL FIELD The present invention relates to a cosmetic which does not have a slip and squeaky feeling at the time of application and which is not shiny.

Prescription examples 1 to 5 (cosmetic fluid)
A cosmetic solution having the composition shown in Table 4 was produced in the same manner as in Examples 1 to 27.
All of the cosmetic solutions thus obtained have no slippage or squeaky feeling at the time of application and no shine at the time of application. Also, the feeling of use is good and the feeling of moisturizing is sustained.

Test Example For the cosmetic of Example 15, the viscosity after storage for 1 hour at 25 ° C. after production was measured using a B-type viscometer (TVB-10 type manufactured by Toki Sangyo Co., Ltd.), rotor No. 3, 6 rpm, It measured on the conditions of 25 degreeC for 1 minute. As a result, it was 14000 mPa · s.
