Description

  The present invention relates to almond oil and / or macadamia nut oil which are plant-derived oils, hexa (hydroxystearic acid / stearic acid / rosinic acid) dipentaerythrityl, lauroylglutamate di (octyldodecyl / phytosteryl / behenyl), macadamia nut fatty acid phytosteryl, stearin The present invention relates to an oily composition containing at least one selected from acid-hydrogenated castor oil.

  The oily composition is a composition mainly composed of an oil agent, and can be imparted with a wide variety of properties depending on the combination of oil agents used, and is widely used in cosmetics and the like because of its excellent moisturizing effect. In recent years, for the purpose of relaxation effect, etc., a plant-derived oil (such as almond oil) is applied to the skin (Patent Document 1), nutritional supplementation to the nail epidermis, and moisturizing effect (plant oil) , Lime oil), cystine, ionized calcium saturated water, etc. (Patent Document 2), a technique using liquid higher alcohol and vegetable oil to obtain a liquid oily body oil that is well-familiar and has good penetration (patent) Literature 3) has been reported, and a composition containing a plant-derived oil having various effects has been demanded.

  In recent years, nail oil compositions used to care for nail epidermis that has been damaged by the use of nail polish, in addition to nourishing and moisturizing effects, such as penetrating feeling, richness feeling and film thickness feeling during use. The thing which is excellent in the field has been calculated | required. As a technique for improving the richness and film thickness of the composition, a technique using an ester compound of isostearic acid having a specific structure (Patent Document 4) has been reported.

Special table 2012-510513 gazette JP 2008-127358 A JP2012-87109A JP 2004-51586 A

  However, in the techniques of Patent Documents 1 to 3, the effect of the plant-derived oil agent can be obtained, but the richness and the film thickness at the time of use cannot be obtained. For example, even if the technique of Patent Document 4 is used for the technique of Patent Document 3, depending on the selected oil agent, there are combinations that change in quality (solidify, etc.) in a low-temperature environment. It was difficult to obtain an oily composition having excellent low-temperature stability that does not deteriorate (solidify, etc.) in a low-temperature environment while being excellent in feel and richness.

  Accordingly, an object of the present invention is to provide an oily composition excellent in low-temperature stability while being excellent in all of a penetrating feeling, a film thickness feeling, and a rich feeling.

(B) Feeling of richness, (b) Feeling of film thickness, (c) Penetration feeling Applying oily compositions for nails of Examples and Comparative Examples to nails to 10 panelists specializing in cosmetics evaluation, and extending and spreading on fingernails Each nail oil composition is evaluated in five levels according to the following criteria, and each nail oil composition is scored for each nail oil composition. The average score was determined according to the following criteria. The evaluation results are also shown in Table 1. In this determination, richness means that when the oily composition for nails is extended and spread, it has an appropriate adhesion to the nails and has a feeling of biting on the nails. Refers to the film feeling of the nail oil composition remaining on the nail after the nail oil composition is extended and spread, and the penetrating feeling is the familiarity with the nail when the nail oil composition is extended and spread. It means that the finish is good and the feel is minimal.
