Description

  The present invention relates to an oily component containing solid oil and a specific dextrin fatty acid ester, and a solid cosmetic containing a powder component containing a spherical powder at a specific mass ratio. More specifically, the present invention has elasticity during use. Yes, it has a unique feeling such as a melt feeling that melts when used with a finger, has a high emollient feeling, smooth and soft feeling, and has a quality such as a smooth and soft finish. Further, the present invention relates to a solid cosmetic that has excellent makeup effect durability and can be used satisfactorily without causing caking.

  Solid cosmetics such as foundations and eye shadows are preferred by consumers because they are simple to use and have excellent portability. Conventionally, as this solid dosage form cosmetic, the amount of powder is small and the amount of oil is small, and the composition containing the powder is obtained by compression molding or the like. Solid powder cosmetics that are preferred for quality such as non-sticky finish, low powder amount, large amount of oil agent, can be obtained by melt filling, etc. Adhesion to the skin because the continuous layer is oil agent In addition, two types of oil-based solid cosmetics that are excellent in emollient have been used.

  Solid powder cosmetics have a smooth finish and are characterized by a smooth and soft feeling of use, but because of the large amount of powder, they are not satisfactory in terms of emollient feeling and sustainability of cosmetic effects. There was no. For this reason, various studies have been made to eliminate these drawbacks. For example, when the content of the oil agent is increased, the emollient feeling is increased, but the so-called caking that the surface becomes hard during use may occur. In addition, there is a technique of processing and containing an oil agent on the surface of the powder, but the quality is not satisfactory because of a dull finish and a smooth and soft feeling.

  Oily solid cosmetics, on the other hand, have a high emollient feeling and excellent makeup effect sustainability, but because of the high oil content, they do not satisfy the smooth and soft feeling of use and the smooth finish. It was. In particular, this dosage form contains a large amount of solid oil in the oil for the purpose of improving the moldability to solid and stability, so the weight of spread at the time of application, the feeling of stickiness of the finish, to the skin Was causing a sense of burden. For this reason, various studies have been made to eliminate these drawbacks. For example, by containing powder with high oil absorption such as porous silicic acid, a smooth finish feeling can be obtained, but the burden on the skin is high, smooth and soft feeling of use and emollient feeling are inferior The quality was not satisfactory.

  The solid range of oil and powder is being investigated as a solid cosmetic that has both a light and smooth finish and solid emollient feeling and long-lasting cosmetic effect. Yes. For example, it contains 5 to 21% by mass of a crosslinked organopolysiloxane obtained by crosslinking an organopolysiloxane, 27 to 80% by mass of a liquid silicone oil, and 14 to 67% by mass of a powder containing a pearl material and / or a mica pigment. Technology to obtain a solid oily cosmetic material with a unique and unique feel in use (Patent Document 1), containing 30-60% by weight of powder containing porous powder and 40-70% by weight of oil However, a technique (Patent Document 2) for obtaining a solid cosmetic with a moist feel and no skin roughness or stickiness has been studied.

JP 2005-314369 A JP-A-9-221404

  However, although these cosmetics have an emollient feeling, they tend to lack a dull finish, and because they contain a large amount of oily components, the cosmetics are displaced in the container due to vibration and impact, and the container In some cases, there was a gap between the wall.

  In view of the above circumstances, the present invention has a unique feeling of use, such as a melt feeling that melts when used with a finger, has a unique feeling of use, has a high emollient feeling, and is not sticky and has a smooth finish. It is an object of the present invention to provide a solid cosmetic that has the quality of the above, is excellent in durability of the makeup effect, and can be used satisfactorily until the end without causing caking.

  The present inventors have intensively studied to solve the above problems. As a result, when solid oil and a specific dextrin fatty acid ester are contained in a solid cosmetic with a lot of oil components to enhance emollient feeling, the adhesion to the skin may be increased, but stickiness and caking may occur. Therefore, it contains an oily component and a powder component at a specific ratio, and also contains a spherical powder in combination, so that the quality such as a smooth finish without stickiness is maintained while maintaining the adhesion to the skin and the emollient feeling. It has been found that it has a long lasting cosmetic effect, can be used satisfactorily without causing caking, and has a unique feeling of melting such as melting when used with a finger. Further, it has been found that the hollow powder is further contained in the spherical powder, and the present invention has been completed by improving the caking and non-stickiness.

  Although content of the component (A1) solid oil used for this invention is not specifically limited, 0.1-10% is preferable in cosmetics, and it is more preferable in it being 2-8%. If it is this range, since it is excellent by the adhesiveness to the skin of cosmetics, an emollient feeling, and the durability of a cosmetic film, it is preferable.

  The dextrin fatty acid ester of the component (A2) used in the solid powder cosmetic of the present invention has the effect of increasing the adhesion to the skin and enhancing the durability of the cosmetic effect. The dextrin fatty acid ester of component (A2) is an esterified product of dextrin and fatty acid, and the average polymerization degree of glucose of dextrin is 3 to 150, and the fatty acid is one kind of branched saturated fatty acid having 4 to 26 carbon atoms or More than 50 mol% and 100 mol% or less with respect to the total fatty acids, and linear saturated fatty acids having 2 to 22 carbon atoms, linear or branched unsaturated fatty acids having 6 to 30 carbon atoms and carbon numbers 6 to 30 1 or 2 or more types selected from the group consisting of cyclic saturated or unsaturated fatty acids of 0 to 50 mol% based on the total fatty acids, and the degree of substitution of fatty acids per glucose unit is 1.0 to 3 0.0, preferably 1.2-2.8 dextrin fatty acid ester.
