Description

  The present invention relates to a vaginal cosmetic comprising a polyethylene wax having an average molecular weight of 900 to 1000, a melting point of 88 to 95 ° C., and a penetration of 75 to 120 dmm, and an α-olefin / vinylpyrrolidone copolymer. The present invention relates to a vase cosmetic that is easy to apply repeatedly, is excellent in volume effect, curl effect and curl sustainability, and has a uniform cosmetic film.

Conventionally, vaginal cosmetics have been used to make the eyes stand out by making the wrinkles stand out thickly or curling the wrinkles. When a large amount of cosmetics is applied to the cocoon in order to improve the volume effect, which is an effect of making the cocoon thick and conspicuous, the cocoon becomes heavy, the heel is lowered over time, and the curling effect may be impaired. Therefore, a technology that combines the effects of both has been studied.
For example, there is a technique including a specific amount of a hard wax wax-in-water emulsion and a polymer system that forms a film that causes specific shrinkage (see, for example, Patent Document 1). Moreover, the technique using special resin called candelilla resin is mention | raise | lifted (for example, refer patent document 2). Furthermore, the technique which examined the ease of superimposition with a volume effect and a curl effect by using wax and / or resin and a hollow powder is mentioned (for example, refer patent document 3).
In addition, in water-in-oil type cosmetics for cosmetics, water, a nonionic surfactant, an eicosene / vinylpyrrolidone copolymer, and a dextrin fatty acid ester are blended in a specific amount, which is an external defect that is a disadvantage of emulsions. For example, a technique that improves the weak point against frictional resistance and poor stability over time and has a curl-up and volume-up effect (see, for example, Patent Document 4).

Japanese Patent No. 29898929 JP 2002-338436 A International Publication No. 2004/087078 Pamphlet JP 2005-170847 A

  As a method for applying cosmetics for vaginal use up to a few years ago, it has been desired that a desired amount of cosmetics adhere to the wrinkles as few times as possible. Consideration has been made. However, recently, it has become more common to obtain a makeup effect that suits the individual by increasing the curl effect and volume effect by combing the wrinkles many times with an applicator with cosmetics. In the prior art, as a result of attaching and fixing a lot of cosmetics for the purpose of improving the volume effect and curl effect, bundling (strengthening of adhesion between wrinkles) occurs, and the flexibility of the coating film There has been a problem in that there has been a shortage of inconvenience and a sense of inconvenience and burden. In addition, the usability of cosmetics is no longer smooth, and when applied repeatedly, the previously applied cosmetics can be removed and become lumpy (non-uniform cosmetic lumps adhere to the wrinkles) or evenly applied There was something I couldn't do. In some cases, a technique for making the contents look thicker by bundling them is desired, but in reality, there are many consumers who want each piece to look thicker.

  For this reason, it has been desired to develop a vaginal cosmetic that is easy to overcoat, finishes in a uniform makeup film without bundling, and has excellent volume and curl effects and curl sustainability.

  In such a situation, the present inventors have intensively studied to solve the above problems, and as a result, instead of the high melting point and high hardness wax usually used in cosmetics for vaginal use, a high melting point and low hardness wax is used. Thus, it has been found that curling power and curling durability can be improved while maintaining ease of overcoating. However, it is insufficient for producing a volume effect while keeping the decorative film uniform. Accordingly, when the α-olefin / vinylpyrrolidone copolymer is used in combination, the adhesiveness of the wax is improved, so that a volume effect that cannot be obtained by each component alone can be obtained, and the present invention has been completed. .

That is, the present invention includes the following components (A) and (B);
(A) polyethylene wax having an average molecular weight of 900 to 1000, a melting point of 88 to 95 ° C., and a penetration of 75 to 120 dmm,
(B) To provide a vaginal cosmetic characterized by blending α-olefin vinylpyrrolidone.

  The present invention provides a vaginal cosmetic that is easy to overcoat, has high adhesion, is excellent in volume effect, curl effect, and curl persistence, and has a uniform cosmetic film.

Hereinafter, the present invention will be described in detail.
The component (A) used in the present invention will be described. The polyethylene wax having a component (A) average molecular weight of 900 to 1000, a melting point of 88 to 95 ° C., and a penetration of 75 to 120 dmm can be used without particular limitation as long as it is usually used in cosmetics. For example, ASENSA PR200 (average molecular weight 900-1000, melting | fusing point 88-95 degreeC, penetration 75-120 dmm) (made by Honeywell) is mentioned as a commercial item.

  The blending amount of the component (A) is preferably 0.5 to 20% by mass (hereinafter simply referred to as “%”), and more preferably 1.5 to 12%. If it is in this range, it will not be bundled or lumped, and satisfactory in terms of volume effect, curl effect and curl sustainability.

Is obtained by
When the average molecular weight of the component (A) is in the range of 900 to 1,000, the combined use with the component (B) can impart sufficient volume effect and curl effect to the wrinkles and impart curl persistence. When the molecular weight is less than 900, the curling effect and curl sustainability are poor, and when the molecular weight exceeds 1000, the adhesion is deteriorated.

The melting point was determined by the method described in the fourth report of the quasi-drug standard general test method melting point measurement method.
When the melting point of the component (A) is in the temperature range of 88 to 95 ° C., a sufficient volume effect can be imparted to the eyelashes by the combined use with the component (B), and a curling effect can be imparted.
When the melting point is less than 88 ° C., the curling effect and curl sustainability are poor, and when the melting point exceeds 95 ° C., the usability is deteriorated.

The penetration is determined by the measurement method described in the ASTM standard.
The sample is heated and melted, taken into a sample container, allowed to cool, and then kept at 25 ° C. in a constant temperature water bath, and a specified needle having a total mass of 100 g is allowed to enter the sample vertically for 5 seconds. The penetration of the sample is expressed by a numerical value obtained by measuring the depth of penetration of the needle up to 0.1 mm and multiplying this by 10 times.
If the penetration of component (A) is in the range of 75 to 120 dmm, sufficient volume effect, curl effect, and curl sustainability can be imparted to the eyelids in combination with component (B).
When the penetration is less than 75 dmm, the curling effect and curl persistence are poor, and when the penetration is more than 120 dmm, the adhesion is deteriorated.
