Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil-based cosmetic, and more particularly to an oil-based cosmetic which is excellent in usability such as smoothness and adhesion upon application, gloss and stability over time.

[0002]

2. Description of the Related Art Conventionally, studies have been made to produce various organoleptic effects by changing the blending amounts of solid oil, semi-solid oil, and liquid oil. In particular, in order to produce a smooth feeling during application, a smooth feeling of use can be generally obtained by blending a large amount of semi-solid oil or liquid oil. In particular, solid or paste-like cosmetics must be blended with a certain amount of solid oil in order to ensure stability under high-temperature conditions, and as a result, the appearance of the system may become opaque. . As a technique for providing a cosmetic having a transparent appearance, there are techniques for blending a dextrin fatty acid ester, heavy liquid isoparaffin and a liquid oil component (Japanese Patent Application Laid-Open No. 9-235210), a polyamide resin and a pentaerythridine diester. And polyglycerin side chain fatty acid partial ester or polyglycerin unsaturated fatty acid partial ester, etc.
No. 8731).

[0003]

However, these cosmetics are not always satisfactory in the usability such as removal and feel of the cosmetics, the luster, and the stability over time such as sweating with time and temperature. .

[0004]

Under these circumstances, the present inventors have conducted intensive studies in order to solve the above-mentioned problems, and as a result, in oily cosmetics, candelilla resin, 12-
By containing hydroxystearic acid and / or dextrin fatty acid ester, an oil-based cosmetic excellent in usability such as smoothness and adhesion at the time of application, gloss, and stability over time can be obtained. Has been found to have excellent transparency, and the present invention has been completed. That is, the present invention contains (A) candelilla resin (B) 12-hydroxystearic acid and / or dextrin fatty acid ester (C) oil, thereby providing usability such as smoothness and adhesion during application, luster, An object of the present invention is to provide an oily cosmetic having excellent stability over time.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail.
