DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oily solid cosmetic containing a specific amount of a non-silicone liquid oil, wax and powder each having a branched structure in the molecule and having fluidity at -20.degree. More particularly, the present invention relates to an oil-based solid cosmetic which is non-greasy at the time of application, has a dry feel, is excellent in spreadability and skin familiarity, and has excellent temperature stability from low temperature to room temperature.

[0002]

2. Description of the Related Art Conventionally, oily solid cosmetics are a type of cosmetic preparation commonly used in makeup cosmetics such as lipstick, foundation, face color, and control. Oil-based solid cosmetics are mainly composed of liquid oil, wax, and powder, and have realized various qualities by changing the blending ratio thereof. Oil-based solid cosmetics are obtained by solidifying liquid oil with wax, and the stability over time depends on the wax structure. If a wax having a relatively high melting point is used, the stability over time in the room temperature region is a good dosage form. It is. Furthermore, in recent years, in spite of being an oily solid cosmetic, a good feeling of elongation and spread is often required so as to be melted on the skin.

[0003]

If a large amount of liquid oil is added to an oily solid cosmetic, it can be stretched so as to be melted on the skin. However, liquid paraffin is selected as the liquid oil to make the oily solid cosmetic. When blended in a large amount, it may feel sticky at the time of application, and when silicone oil is selected as a liquid oil and blended in a large amount in an oily solid cosmetic,
There was a case where a slippery feeling was caused at the time of application, and the skin familiarity became poor. For this reason, products have been developed in which a large amount of liquid oil having a branch in the molecule is blended, but depending on the type of the liquid oil having a branch in the molecule, one that solidifies in a low temperature region of about -20 ° C is used. In some cases, when the oily solid cosmetic containing such an oil agent is once left in a low-temperature region and then returned to room temperature, the gel structure of the wax may be broken and the solidity may be lost. That is, during storage in a warehouse in winter or during transportation by air, the cosmetic is reduced by -2.
There is a case where it is left in a low temperature region of about 0 ° C., and such a problem may occur. For this reason, there has been a demand for development of an oily solid cosmetic which is not sticky at the time of application, has a smooth feel, is excellent in spreadability and skin familiarity, and has excellent temperature stability from low temperature to room temperature.

[0004]

Under these circumstances, the present inventors have conducted intensive studies and as a result, have found that non-silicone liquid oils having a branched structure in the molecule and having fluidity at -20 ° C. It has been found that an oily solid cosmetic containing a specific amount of a wax, a powder, and a powder respectively has a small change in the phase structure of the entire system even in an extremely low temperature range (-20 to 0 ° C), and further solves the above-mentioned problems. Heading, the present invention has been completed.

That is, the present invention provides the following components (a) to
(C); (a) a non-silicone liquid oil having a branched structure in the molecule and having fluidity at -20 ° C 50 to 85% by mass (b) wax 5 to 15% by mass (c) powder It is intended to provide an oil-based solid cosmetic characterized by containing 10 to 35% by mass. Further, the component (a) is one or more selected from glyceryl tri-2-ethylhexanoate, neopentyl glycol di-2-ethylhexanoate, isotridecyl isononanoate, and isononyl isononanoate. The present invention provides the above-mentioned oily solid cosmetic. Further, the present invention provides any of the above oily solid cosmetics, wherein the cosmetic is in the form of a stick.
