Description

  The present invention relates to a stick-shaped makeup remover comprising a solid oil having a melting point of 70 ° C. or higher, a dialkyl carbonate having an alkyl group having 14 to 15 carbon atoms, and a powder. The present invention relates to a stick-like makeup remover that has no stickiness, is particularly suitable for partially removing a makeup film, and also has a makeup base effect that can be easily applied to the skin after the makeup is removed.

  Makeup remover is a cosmetic that removes dirt and makeup on the skin. It is a lotion type that wipes off dirt with cotton, a sheet type that is impregnated with a lotion type into a non-woven fabric, and massage. A cream type or a solid type that is wiped with cotton after being blended with dirt can be used. The lotion type makeup remover has the advantage of being easy to use and easy to adjust the feel of the back skin, and the cream type and solid type can be formulated with a lot of oil, It is often used when removing makeup cosmetics.

Among these, various solid makeup removers have been studied because of their ease of use and excellent portability.
For example, a technique for obtaining a transparent to translucent appearance by combining a nonionic surfactant and a liquid oil (see, for example, Patent Document 1), a solid oil having a melting point of 50 ° C to 150 ° C, and a nonionic surfactant A technique for combining agents (for example, see Patent Document 2), a technique for improving the effect of removing a decorative film by combining solid oil, powder, and liquid oil having a melting point of 45 ° C to 120 ° C (for example, see Patent Document 3) ), A technique for improving the removal effect and usability of the cosmetic film by combining solid oil having a melting point of 30 ° C. to 60 ° C., solid oil having a melting point of 61 ° C. to 110 ° C., and powder (see, for example, Patent Document 4) )was there.
Sho 62-108806 (pages 1 to 4) JP 2001-213726 A (pages 1 to 6) JP 2002-322029 A (pages 1 to 5) JP 2002-302421 PR (pages 1 to 10)

  However, in the techniques of Patent Documents 1 and 2, although the effect of removing the decorative film can be improved by using a combination of surfactants, the sticky feeling after use remains, and when the makeup is applied again, There was a drawback of causing unevenness. In the technique of Patent Document 3, liquid oil and powder can be blended in place of the surfactant to reduce the effect of removing the cosmetic film and reduce the stickiness. However, with certain liquid oils, the stickiness is reduced. It is necessary to add a large amount of powder to the skin, and as a result, the skin per touch at the time of use is hard, and satisfactory products may not be obtained in terms of usability. In addition, in the technique of Patent Document 4, in order to soften the skin area at the time of use, solid oil with a low melting point can be combined to alleviate irritation to the skin. It was not satisfactory with the unevenness of the decorative film when applying.

  For this reason, it is soft to the skin, does not feel sticky after use, is particularly suitable for partially removing the makeup film, and can be easily applied to the skin after removing the makeup. Development of a stick-shaped makeup remover that has both effects has been desired.

  Therefore, as a result of intensive studies to solve the above problems, the present inventors have found that in a stick-like makeup remover, a solid oil having a melting point of 70 ° C. or higher, a dialkyl carbonate having an alkyl substituent having 14 to 15 carbon atoms, and By combining the powder, a stick-like makeup remover that has a soft base feel, no stickiness after use, and can be re-applied even after partial removal of the makeup film is also obtained. As a result, the present invention has been completed.

  That is, the present invention provides (A) a solid oil having a melting point of 70 ° C. or higher, (B) a dialkyl carbonate mainly having an alkyl group having 14 to 15 carbon atoms, and (C) a stick-like makeup remover containing powder. To do.

  The stick-like makeup remover of the present invention is soft on the skin and does not feel sticky after use, and is particularly suitable for partially removing the makeup film. Further, it can be easily applied to the skin after removing the makeup. There is an advantage of having a makeup base effect that can be applied.

Hereinafter, the present invention will be described in detail.
The solid oil having the melting point of component (A) used in the stick-shaped makeup remover of the present invention having a melting point of 70 ° C. or higher is particularly used as long as it is used for maintaining a stick shape in the present invention and usually used in cosmetics.
