Description

The present invention relates to a water-containing cosmetic for cosmetics, which is excellent in long rush effect, volume effect and sustainability thereof, and has good usability because of no bundling, and has excellent finished film uniformity. Regarding cosmetics.

Cosmetics for eyelids have a cosmetic effect that makes the eyes clear by curling the eyelids or making the eyelids thick and long.
These vaginal cosmetics are mainly composed of solid oils such as waxes, waxes, oil-soluble resins and powders, and film-forming agents, and are comfortable to use as cosmetics, feel in use, and functionality. In order to produce the above, studies have been made on blending waxes having various properties and properties, oil-soluble resins, powders, and film forming agents. In addition, in order to obtain the effect of making wrinkles look longer (long rush effect), a technique of blending short fibers such as nylon has been studied.
As a means to improve the adhesion of cosmetics and improve the stickiness of the fiber, a lot of solid components such as wax and oil-soluble resin are blended, and the adhesiveness of the water-soluble polymer is used to make the fiber wrinkle. There is a technique (for example, see Patent Document 1) that improves the attachment. This long rush effect was mostly obtained by blending fibers. On the other hand, a technique has been studied in which high-polymerization polyethylene glycol used as a thickener or pigment dispersant is used in cosmetics for vaginal skin to improve its volume and to have a long-lasting effect. (For example, refer to Patent Document 2).

JP-A-7-267827 Japanese Patent Laid-Open No. 11-79940

However, using the water-soluble polymer film-forming ability to give a volume effect or long lash effect to the cocoon, although a certain volume effect is obtained, the long lash effect is obtained when fibers are used. It was considerably inferior to the effect. Further, when the molecular weight of the high-polymerization polyethylene glycol is low, almost no effect is obtained, and even if the molecular weight is high, the long rush effect is not obtained as expected. If the blending amount is increased in order to obtain a higher effect, the wrinkles will be bundled without leaving one by one, or it will be too long and unnaturally long, leading to deterioration in usability, Sometimes makeup collapse occurred due to sweat and tears.

Therefore, the present inventors have conducted extensive research to solve the above-mentioned problems, and as a result, by combining a water-soluble polymer having spinnability in an aqueous solution with an α-olefin / vinylpyrrolidone copolymer, When applied to the skin, the cosmetic film extends to a little longer than the tip of the hair, the tip is not fooled, the effect is as if the wrinkles have become longer (long rush effect), and the volume effect is also obtained I found it. Furthermore, the present inventors have found that a water-containing cosmetic for cosmetics having excellent cosmetic effect durability, no bundling, good usability, and excellent finished film uniformity can be obtained, and the present invention has been completed. It was.
That is, the present invention provides the following components (A) and (B):
(A) High polymerization degree polyethylene glycol having a molecular weight of 2 to 7 million (B) An oil-soluble copolymer of α-olefin and vinylpyrrolidone selected from hexadecene and eicosene It is a fee.
