Description

The present invention relates to a cosmetic composition containing a silicone powder, ethanol, and an oil agent which is liquid at 25° C. and has an IOB value of 0.3 or less. More specifically, the present invention relates to powder caking even when left standing for a long period of time. The present invention relates to a cosmetic composition which is less likely to cause stains, has excellent redispersibility of powder, and has a non-greasy feeling in use.

The composition containing the powder is intended for the astringent effect due to the powder, the sebum adsorption effect, the soft focus effect, the feeling of non-greasy feeling, and the like. Inorganic powders such as zinc and titanium oxide, organic powders such as silicone, polymethylmethacrylate and cellulose have been used.

However, there is a problem that these powders settle in the composition, and when left standing for a long period of time, they solidify (cake) on the bottom surface of the container, resulting in a decrease in redispersibility.

Conventionally, for the purpose of improving the redispersibility of powder in the composition, studies have been made to improve the dispersibility of the powder by containing a surfactant (see, for example, Patent Document 1), and a powder having a small specific gravity is prepared. Studies have been conducted to suppress the caking of the powder (for example, Patent Documents 2 and 3) or the like by containing it or by containing several kinds of powders having different specific surface areas.

However, while the surfactant improves the dispersibility of the powder and suppresses caking, it affects the feeling of use even when the content is small, and therefore it is difficult to obtain a composition without stickiness. It was The use of several types of powders with different specific surface areas also improves the redispersibility of the powder, while it is sufficient if a high proportion of ethanol is included in order to obtain a fresher, non-sticky feel. No effect was obtained. Therefore, while containing a high proportion of ethanol, caking of the powder is less likely to occur even when allowed to stand for a long time, excellent redispersibility, and development of a composition excellent in feeling of use without stickiness is desired. It was

Under such circumstances, the present inventor has earnestly studied to obtain a cosmetic composition that can suppress the caking of silicone powder in a cosmetic composition containing a large amount of ethanol. At that time, by containing an oil agent having a surface polarity close to that of the silicone powder and limiting the content ratio of the content of ethanol and the content of the oil agent, unexpectedly, it is difficult for the powder to caking even when left standing for a long time. It was found that the dispersibility tends to be excellent. As a result of further studies, the inventors have found that the content mass ratio of ethanol and liquid oil having an IOB value of 0.3 or less is particularly excellent at 2:1 to 1:2, and have completed the present invention.

If the content of the component (C) is less than this range, the effects of suppressing caking and improving the redispersibility of the powder are not sufficient, and if the content of the component (C) is more than this range, it becomes sticky. It is impossible to achieve a good usability. Further, the content mass ratio (B):(C) of the component (B) and the component (C) is preferably 3:2 to 2:3.
