Description

  The present invention relates to an oily cosmetic, and in particular, is an oily cosmetic that stably contains a fluoroalkyl group-containing organopolysiloxane, has good affinity and adhesion to the skin, is non-sticky, and has water resistance and sebum resistance. The present invention provides an oily cosmetic material that is excellent in makeup, such as fragility and migration resistance (the cosmetic film does not transfer to other substances).

Conventionally, oily cosmetics are excellent in emollient, usability, gloss, etc., so they are widely applied to make-up products such as lipsticks, lip glosses and foundations, as well as basic cosmetics such as oily eye creams, cleansings and hair waxes. ing. However, oily cosmetics have a stickiness peculiar to oils and the elongation at the time of application is heavy, and it has been studied to eliminate these problems and to prevent oily makeup due to sweat and sebum and to obtain oily cosmetics with good makeup. I came.
For example, there is a technique for eliminating stickiness and elongation weight peculiar to oily cosmetics by using low-viscosity silicone oil (Non-Patent Document 1), but silicone oil cannot prevent makeup collapse due to sebum. In many cases, substances having water resistance and oil resistance were examined. Therefore, the so-called fluorine-based oil agent having a perfluoroalkyl group in the molecule has a very low interfacial tension, an excellent water resistance, and an excellent sebum resistance, thereby improving the longevity of the makeup. It has attracted attention as a raw material and has been formulated into cosmetics. However, since fluorine-based oils are inferior in affinity with other oils and cannot fully utilize the characteristics of fluorine-based oils, recently, studies have been made on stably blending them into cosmetics. For example, by combining a nonionic active agent having a polyoxyethylene chain, a technique that improves makeup (patent documents 1 and 2), a fluorine-modified silicone is stably blended in cosmetics, and water is also added. The development of specific silicone polymers has also been studied for the purpose of stable blending. (For example, Patent Document 3)

New Cosmetic Sciences Second Edition (Nanzan-do) January 18, 2001 145 Japanese Patent No. 3200242 Japanese Patent No. 3200347 JP 2001-342255 A

However, in the method of combining the specific active agents, the wetness to the sebum is easily promoted by the active agents, so that it is difficult to sufficiently exhibit the sebum resistance inherent in the fluorinated oil agent. Furthermore, since the fluorinated oil was blended in a liquid state, the effect of migration resistance could not be expressed. When the specific silicone polymer is used, it is possible to stably blend fluorine-modified silicone, but since it has poor affinity and adhesion to the skin, a uniform cosmetic film cannot be formed, there is a makeup float, emollient There were cases where problems such as inability to obtain a feeling occurred.
Accordingly, it has been desired to develop an oily cosmetic that has good affinity and adhesion to the skin, is non-sticky, and has excellent makeup properties such as water resistance, sebum resistance, and migration resistance.

In such a situation, the present inventors have conducted extensive studies to solve the above problems, and as a result, the fluoroalkyl group-containing organopolysiloxane is obtained by combining a fluoroalkyl group-containing organopolysiloxane and a specific silicone polymer. It has been found that a non-volatile oil that is liquid at room temperature that is not uniformly mixed with can be stably blended into an oily cosmetic. Further, in the decorative film after application, the liquid non-volatile oil gradually moves to the skin side at the normal temperature having a high affinity with the skin, and accordingly, the layer close to the surface of the decorative film is formed with a specific silicone polymer. Since the fluoroalkyl group-containing organopolysiloxane is relatively increased, the present inventors have found that the above-mentioned problems such as sufficient emollient feeling and makeup feeling can be solved, and the present invention has been completed.

  As shown in Table 1, all of the products of the present invention have no stickiness, light elongation, emollient feeling, affinity with skin, excellent adhesion, water resistance, sebum resistance, and migration resistance. It was an excellent oil-based foundation for comprehensive makeup. Moreover, what was further superior when the components (A) and (B) were used in the form of a paste was obtained. On the other hand, the comparative product is inferior to the product of the present invention, and the comparative product 1 which does not contain the component (A) is not resistant to migration and has a comprehensive makeup, but instead of the components (A) and (B), Comparative product 2 containing a cross-linked methylpolysiloxane mixture containing no alkyl group is light in elongation, sebum resistance, and migration resistance, and comparative product 3 containing no component (B) is emollient, adhesive, Comparative product 4 that contains non-volatile oil that does not contain component (C) and is miscible with component (B) instead of component (C) in water resistance, sebum resistance, and overall makeup, has emollient feeling, migration resistance, In synthetic makeup, comparative product 5 using a surfactant instead of component (A) does not contain component (A) in sebum resistance, migration resistance, synthetic makeup, Comparative product 6 containing a large amount of B) is adhesive. Migration, in the overall makeup rice cake, were those particularly poor.
