Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention has a light and smooth feeling during application and suppresses a perspiration phenomenon over time.
The present invention relates to an oily cosmetic having improved stability. More specifically, it relates to an oily cosmetic containing an organically modified clay mineral, polyoxyethylene hydrogenated castor oil, and ester oil.

[0002]

BACKGROUND OF THE INVENTION Oily components are solidified with waxes,
Alternatively, organically modified clay minerals, oily cosmetics prepared as a gel with an oil gelling agent such as aluminum 12-hydroxystearate, have good emollient effect because they have good adhesion and spread to the skin and are hard to lose makeup. In particular, it is offered as makeup cosmetics such as oily foundation, oily blusher, oily eye color and oily lipstick.

Such oily cosmetics contain a large amount of natural oily raw materials and ester oils having a certain degree of polarity for the purpose of lightening and smoothing the elongation during use. However, such a polar oily material absorbs moisture over time, and a phenomenon called so-called sweating, in which the liquid exudes in the form of water droplets on the surface of the oily cosmetic, often occurs, and the product value is often impaired.

[0004]

SUMMARY OF THE INVENTION Therefore, in the present invention, it is an object of the present invention to obtain an oily cosmetic which suppresses the sweating phenomenon while maintaining the light elongation and smoothness during use, and which has good stability over time. And Furthermore, we have decided to improve the gloss of the cosmetics.

[0005]

[Means for Solving the Problems] Various investigations have been made to solve the above problems. As a result, an oily cosmetic is prepared by using one or more kinds of organically modified clay minerals, polyoxyethylene hydrogenated castor oil, and ester oil in combination. It was found that, by blending with, the oil-based cosmetic which suppresses the sweating phenomenon and has good stability over time can be obtained while maintaining the light elongation and smoothness during use, and thus completed the present invention. It was

With respect to each of the examples of the present invention described above, the feeling of use, the luster of the appearance, and the sweating were evaluated. At that time, each comparative example shown in Table 1 was evaluated at the same time.

[0023]

[Table 1]

Regarding the feeling of use, sensory evaluation was performed by 10 panelists for light elongation and smoothness during use, and the results were scored according to the following criteria, and the average value was calculated.

[Lightening] when used Very light; 3 points Light; 2 points Slightly heavy; 1 point Heavy; 0 points

Smoothness in use Very smooth; 3 points Smooth; 2 points Not very smooth; 1 point Not smooth; 0 points

The gloss of the appearance was evaluated by 10 panelists by visual observation, and scored as "yes; 3 points", "somewhat; 2 points", "not; 1 point", and 10 persons evaluated. The average value of the points was calculated. Regarding sweating, after leaving each of the example and the comparative example at room temperature for one week,
The sample was transferred to a constant temperature bath of 40 ° C. and left standing for 1 week, and the change in state was visually observed. The result was that "no sweating was observed; ○",
It was expressed as "slight sweating is recognized; △", "prominent sweating is recognized; x". The above results are summarized in Table 2.

[0028]

[Table 2]

As is clear from Table 2, in all of the items of Examples 1 to 6 of the present invention, good results were obtained, but from Example 5, methyl distearyl ammonium bentonite gelled into oil. In Comparative Example 1 substituting aluminum 12-hydroxystearate which is generally used as an agent and Comparative Example 2 in which the polyoxyethylene hydrogenated castor oil added at the time of gel preparation was not blended, remarkable sweating was observed. It was

In the above examples of the present invention, no change in state other than perspiration was observed, and neither skin irritation nor sensitization was observed during use.
