Description

  In the present invention, (A) silicone surfactant, (B) isoparaffin, and (C) dextrin fatty acid ester are blended, and the aqueous phase is 70 to 85% by mass (hereinafter simply referred to as%) in the total composition. It is related to makeup remover. More specifically, it has a refreshing feeling on the back skin and excellent usability (less sagging on the skin and low permeability to cotton), water resistance / oil resistance The present invention relates to a water-in-oil emulsified makeup remover that can easily remove makeup cosmetics with high properties.

Various functional materials are applied to make-up cosmetics in order to improve the longevity of makeup. Specifically, an oil-soluble resin having high adhesion and water resistance is blended as a powder surface treatment agent or as a part of an oil agent, and a makeup cosmetic in which a fluorine compound having high oil resistance is blended. Many. Compositions and cleansing cosmetics in various emulsion forms such as a water-in-oil type, an oil-in-water type, an oily type, and a multilayer type have been studied as makeup removers for removing these. For example, cleansing cosmetics containing a specific oil component (see, for example, Patent Document 1), oil-in-water emulsion makeup remover (see, for example, Patent Document 2) that combines isoparaffin and a polyoxyethylene alkyl ether-based active agent. ) Has a smooth feeling of use, which is a characteristic of an emulsification type, by blending an oil agent that is familiar to makeup cosmetics. Moreover, since the gel composition (for example, refer patent document 3) which combined the specific oil-based component and bridge | crosslinking-type organopolysiloxane is comprised only with an oil agent, its removal effect is high, and it is liquid by using a gelling agent. It can be made into various shapes according to use up to gel. Furthermore, to reduce the use of emulsifiers or to change the appearance, there are two-layered types that have different layers of aqueous and oily components and are used by shaking during use. A multi-layer technique such as a blended three-layer technique (for example, see Patent Documents 4 and 5) is disclosed.
On the other hand, a technique for blending a specific silicone surfactant to obtain a stable water-in-oil emulsion containing a large amount of water (see, for example, Patent Document 6) is also disclosed.

Japanese Laid-Open Patent Publication No. 2003-160436 Japanese Patent No. 2994830 Japanese Patent No. 30018847 JP 2002-114636 A Japanese Patent No. 3363653 JP 2001-059054 PR

However, although the technique of Document 1 has a large amount of oil and an excellent makeup cosmetic removal effect, there is a drawback that stickiness remains on the back skin. In addition, since the viscosity of the technique of Document 2 is too low, it will dripping (runs down before becoming familiar with makeup cosmetics on the skin) or penetrates too quickly when taken out onto cotton, making up cosmetics on the skin. There were drawbacks in terms of usability, such as taking time to blend in. In addition, since it is an oil-in-water type, it may take some time to become familiar with cosmetics. In recent years, it has a removal effect on water- and oil-resistant cosmetics that were developed mainly for improving makeup durability. It was not satisfactory. Since the technique of Document 3 is composed only of an oil agent, there is a problem that stickiness remains on the back skin although the makeup cosmetic removal effect is high. In the techniques of References 4 and 5, it is possible to suppress the stickiness of the back skin by using a multi-layered dosage form with a reduced oil content, but the viscosity is low and there are drawbacks in usability such as sagging. . In addition, since it is shaken during use to disperse the oily component in the aqueous phase, it takes time to become familiar with cosmetics as in the case of oil-in-water dosage forms, and the makeup cosmetic removal effect is not satisfactory. It was. Further, in the technique of Reference 6, since the emulsified state on the skin is unstable, the emulsified droplets are broken during use and the familiarity with the cosmetic is inhibited, so that the makeup cosmetic removal effect is satisfactory. It was not a thing.
Therefore, there has been a demand for the development of a makeup remover that has a refreshing feeling on the back skin, has no sagging, and can easily remove makeup cosmetics with high water / oil resistance.

  Therefore, as a result of intensive research to solve the above problems, the present inventors have dispersed the aqueous component using a silicone-based surfactant in an oily component containing isoparaffin, thereby refreshing the back skin.
