Description

  The present invention relates to an oil-in-oil lip cosmetic.

  Various studies have been conducted in order to increase the persistence of the makeup effect of lip cosmetics. Among them, a wide range of methods have been adopted in which volatile oils such as volatile silicones and volatile hydrocarbon oils are mixed with resins such as silicone resins, and the cosmetic effect is sustained by a resin film formed after volatilization of the volatile oils. Has been. However, with this method, it is difficult to avoid dry feeling of the lips due to volatilization of volatile oil, loss of gloss of the cosmetic coating film, discomfort of the lips due to the resin film, etc., and as a result, it can be comprehensively satisfied as a lip cosmetic. I can't get quality.

  Patent Document 1 proposes an oily cosmetic that improves the sustainability of the cosmetic effect while avoiding the drawbacks of the volatile type color-continuation lipstick as described above by using a fluoropolyether co-modified silicone. However, although the persistence of the cosmetic effect has been enhanced by the use of the fluoropolyether co-modified silicone, the color transfer resistance to a cup or the like has not reached a sufficiently satisfactory level.

  In addition, conventionally, a method of blending a large amount of high-viscosity oil such as heavy fluid isoparaffin or polyisobutylene has been widely used in order to improve glossiness and makeup durability, but the elongation during use becomes heavy. It had drawbacks such as a feeling of stickiness in the finish, and it did not reach an overall satisfactory level.

  On the other hand, a liquid multi-branched ester compound having a specific structure and an oily gel are combined with a large amount of phenyl-modified silicone, and there is no stickiness, excellent color transfer resistance, and long-lasting cosmetic effect. Lip cosmetics with good stability have been proposed (Patent Document 2).

JP 7-233026 A JP 2012-149041

  However, in the technique of Patent Document 2, there is no stickiness, but the color transfer resistance to a cup or the like has not yet reached a sufficiently satisfactory level.

  Accordingly, the present invention relates to an oil-in-oil lip cosmetic that is non-sticky, has an excellent makeup effect, has excellent stability, and has excellent color transfer resistance.

  As a result of earnest research, the present inventor, together with a specific amount of phenyl-modified silicone, a high-viscosity nonvolatile ester oil that is not compatible with the phenyl-modified silicone even at high temperatures, a dextrin fatty acid ester, and a volatile hydrocarbon It was found that an oil-in-oil type lip cosmetic satisfying the above requirements can be obtained by combining and blending.
