Description

  The present invention relates to an oily cosmetic, and more particularly relates to an oily cosmetic excellent in the feel and gloss at the time of application, the persistence of a moisturizing feeling, the dispersibility of pigments, and the sustainability of a cosmetic effect.

  Conventionally, various studies have been made to increase the persistence of the cosmetic effect of oily cosmetics. Among them, a method has been widely adopted in which a volatile oil such as volatile silicone or volatile hydrocarbon oil is mixed with a resin such as silicone resin, and the cosmetic effect is maintained by a resin film formed after volatilization of the volatile oil. Yes. However, with this method, it is difficult to avoid the dryness of the skin due to volatile oil, the loss of glossiness of the cosmetic coating, the uncomfortable feeling of the skin due to the resin coating, and as a result, it is not possible to obtain a comprehensively satisfactory quality. . Silicone resins are extremely incompatible with high-viscosity hydrocarbon oils such as hydrogenated polyisobutene that are most commonly used to achieve a high level of gloss when cosmetics are applied. The composition could not be stably blended, and as a result, the cosmetic effect did not reach a sufficiently satisfactory level for gloss. Furthermore, since it is extremely incompatible with commonly used high-viscosity ester oils and triglycerides formulated to achieve a moist feeling in oily cosmetics, it cannot be stably blended, resulting in a cosmetic effect. The level of moisture was not satisfactory. Therefore, it has been desired to develop an oily cosmetic material realized at a higher level with respect to the feel and gloss when applied, the persistence of moisturizing feeling, the dispersibility of the pigment, and the sustainability of the cosmetic effect.

  The liquid ester composition obtained by esterifying the branched isostearic acid represented by the following general formula (1) is a high-viscosity ester oil, and its blending feel and gloss at the time of application, persistence of moist feeling, and It has been known to improve pigment dispersibility (Patent Document 1). However, the effect of using these together with a silicone resin has not been known at all.
