Embodiment

[0074] First, the production method of the film used for the cosmetic method of this invention is shown.

[0075] ?Film production method

[0076] All the operations were performed by installing a spin coater (Opticoat MS-A 150, manufactured by MIKASA) in a clean room (Class 10,000).

[0077] The silicon substrate (manufactured by KST World Company) was cut into 4cm×4cm, at 120°C in SPM (H 2 SO 4 / H 2 O 2.3:1 (v / v)) was immersed for 10 minutes, and then washed with ion-exchanged water (resistivity: 18 MΩcm). This substrate was set on a spin coater, and 500 μL of poly-L lactic acid (hereinafter referred to as PLA) dichloromethane solution (Mw: 100,000, manufactured by Polysiens Co., Ltd., 20 mg / mL) was dripped and spin-coated (4000 rpm, 20 seconds) , to obtain a poly-L-lactic acid film. When the thickness of the obtained poly-L-lactic acid film was measured using an atomic force microscope (manufactured by Keyence Corporation), the thickness was 120 nm.

[0089] Depend on Figure 4 It was found that by attaching the base film after applying the cosmetic cosmetics, the cosmetic cosmetics are less likely to come off, the makeup durability is improved, and the secondary adhesion prevention effect is excellent.

[0090] The inventors of the present invention produced a film by the above-mentioned production method, and studied the ultraviolet absorption effect of the substrate film when used in combination with sunscreen cosmetics.

[0091] That is, the absorptivity in the ultraviolet region of the samples coated with the sunscreen cosmetics of the following Reference Examples 2 to 4 on the PMMA plate was measured. Thereafter, a base film was attached to each sample, and the absorbance in the ultraviolet region of the same portion was measured. In addition, it measured at 25 degreeC using the U-3500 automatic recording spectrophotometer (made by Hitachi).

[0092] The results o...

Abstract

The present invention provides a cosmetic method having a superior effect of preventing secondary adhesion. The cosmetic method has a step for applying a cosmetic material to skin, a step for pasting the base material film surface of a thin film to skin, and a step for eliminating the support body of the pasted thin film, and is characterized by the thin film comprising a support body and a base material film having a thickness of 10-500 nm.

Description

[0001] Relevant application [0002] The application of the Japanese patent application applied for on October 12, 2012, which was applied for the preferential rights of the national patent applications No. 2012-227076, and included it into the present invention. Technical field [0003] The invention involves beauty methods, especially the excellent beauty methods that involve secondary attachment prevention effects (secondary paying ス effect). Background technique [0004] Mix a large amount of pigment and other colors such as foundation, blush, eye shadow, lipstick and other beauty cosmetics.It is known that in order to achieve the so -called secondary attachment to prevent the effects of this beauty cosmetics, the effect of a mixed patent literature 1 recorded by the mixed patent literature 1.However, it is difficult to achieve secondary attachment to stimulation such as wiping. [0005] On the other hand, ultraviolet rays can bring all adverse effects on the skin.Therefore, i...
