Description

  The present invention is sticky by adding a silicone film-forming agent and a specific amphiphilic associative thickener to a water-in-oil emulsion cosmetic containing a volatile oil agent, a silicone surfactant, and a hydrophobic powder. Further, the present invention relates to a cosmetic that not only improves the uniformity of the cosmetic film, but also prevents the pores from falling off and improves the makeup sustainability.

  Water-in-oil emulsified cosmetics are cosmetics often used in skin care cosmetics and makeup cosmetics, especially base makeup items such as foundations.

  In water-in-oil type emulsified cosmetics, the oil agent is easy to blend into the skin and easily stretch, and therefore, there is a problem that the powder dispersed in the cosmetics tends to easily enter the pores and easily drop off over time. As an example of a water-in-oil emulsified cosmetic, there is a cosmetic that reduces stickiness and realizes a light spread by combining a volatile oil, a silicone surfactant, and a hydrophobic powder. However, water-in-oil emulsified cosmetics that simply contain volatile oils, silicone surfactants, and hydrophobic powders have poor powder adhesion on the skin and can easily enter pores during application. It was easy to fall. The pore loss of the powder at the time of application is caused by the fact that the cosmetic and the powder are too stretched and spread together. Therefore, in order to prevent pore removal, an oily gelling agent may be contained in order to increase the viscosity of the oily component in the cosmetic. However, when an oily gelling agent is contained, the spread of expansion is moderately suppressed and pore removal is suppressed to some extent, but stickiness occurs, and the makeup film tends to become non-uniform, resulting in conspicuous pore removal. there were.

  Similarly, a technique (Patent Document 1) containing a specific amphiphilic associative thickener has been developed in order to increase the viscosity of the aqueous component in cosmetics. As a result, although pore removal immediately after application was not observed, the powder pores dropped over time, and the quality was not satisfactory. In order to prevent the pores of the powder from dropping off with the passage of time, when an oil-soluble polymer was further contained, stickiness or nulliness was generated, and the cosmetic film was likely to be non-uniform during application, and uneven coating was observed.

JP 2010-111634 A

  However, with the conventional technology, even when preventing pore removal at the time of application and over time, stickiness, nulliness, and uneven coating can occur, resulting in a non-uniform makeup film, which is satisfactory for pore removal and stickiness, and a uniform makeup film. Realizing quality was difficult. That is, an object of the present invention is to develop a water-in-oil emulsified cosmetic that does not cause pore removal at the time of application and over time, and does not have stickiness or nullity, and can provide a uniform cosmetic film.

  In view of such circumstances, the present inventors have a water-in-oil emulsified cosmetic containing a volatile oil agent, a silicone surfactant, and a hydrophobic powder. As a result of intensive studies to realize a quality that is difficult to remove pores over time and does not impair the finish at the time of application, the above-mentioned water-in-oil emulsified cosmetic contains a silicone film forming agent and a specific amphiphilic associative thickener. In combination, it has been found that a water-in-oil emulsified cosmetic that can form a smooth and uniform cosmetic film and that can maintain excellent finish quality without causing pores to fall off over time, The present invention has been completed based on these findings.

Represents a branched chain or a secondary hydrocarbon group, m is a number of 2 or more, h is a number of 1 or more, and k and n are independently numbers in the range of 0 to 1000. ]
