[0258] Hereinafter, although an Example demonstrates this invention in detail, this invention is not limited to this.

[0259] [Preparation of Astaxanthin Emulsion A1]

[0260] The aqueous phase composition A1 was obtained by heating and dissolving the following components at 70 degreeC for 1 hour.

[0261] - Combination of Aqueous Phase Composition A1 -

[0262]

[0263] Oil phase composition A1 was obtained by heating and dissolving the following components at 70 degreeC for 1 hour.

[0264] -Combination of oil phase composition A1-

[0265]

[0266] While maintaining 70°C, use an ultrasonic homogenizer (model: HP93, SMT CO., LTD.) to stir the obtained water phase composition A1 at 10,000 rpm (10,000 times / minute), and add the oil phase composition to it Substance A1, thus obtaining a coarse emulsified product.

[0267] Next, the obtained crude emulsion was cooled to about 40° C., and high-pressure emulsified under a pressure of 200 MPa using an ultra-high pressure...

Abstract

The invention provides a transparent cosmetic which is excellent in stability of astaxanthin, has good compatible feeling to the skin, can give a moisture-retaining feeling and is suppressed in sticky feeling during drying. Provided is a transparent cosmetic which comprises astaxanthin, 0.3 to 6 mass% of a compound comprising ascorbic acid, an ascorbic acid derivative and a salt thereof based on the total amount of the transparent cosmetic, 0.01 to 1 mass% of thickening polysaccharides based on the total amount of the transparent cosmetic, 1 to 10 mass% of glycerin based on the total amount of the transparent cosmetic and a compound comprising a compound represented by the formula (1) and a compound represented by the formula (2).

Description

technical field [0001] The present invention relates to a transparent cosmetic material. Background technique [0002] It is known that astaxanthin has a high ability to eliminate singlet oxygen and has an effect of inhibiting skin photoaging caused by singlet oxygen, and is widely used in cosmetic materials. [0003] However, astaxanthin is required to improve its own stability, so when astaxanthin is incorporated into cosmetic materials, antioxidants are often used at the same time. As the antioxidant to be used, ionic antioxidants such as ascorbyl phosphate are used. [0004] On the other hand, techniques for imparting viscosity to cosmetic materials by various methods are being studied for the purpose of improving skin affinity and the like. [0005] As methods for imparting viscosity to cosmetic materials, methods using polymers (carbomer, etc.) having a thickening mechanism based on electrostatic repulsion, methods using thickening polysaccharides, and methods using ...
