Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a makeup cosmetic that provides a smooth feel and a dry feel when applied, has good makeup retention after application, and has high stability over time.

(Prior art) Conventionally, makeup cosmetics containing volatile oils evaporate and decrease over the course of an hour, and as a result, they become hard and unusable when applied, or they become thinner. There was a problem that it would fall out of the container.

Another drawback is that the cosmetic container must be shaped into a complicated shape in order to prevent this reduction in volatilization.

(Problems to be Solved by the Invention) The present invention has discovered a component that retains volatile oil in products in order to suppress the decrease in volatility of volatile oil in cyclic silicone over time, and has incorporated this component into cosmetic formulations. This was achieved as a result of intensive research with the aim of eliminating the drawbacks such as unusability as described above and obtaining a makeup cosmetic with high stability over time even in a simple container.

(Means for Solving the Problems) That is, the makeup cosmetic of the present invention comprises a cyclic silicone tetramer and/or pentamer, silicic anhydride, organic bentonite, soybean phospholipid, propylene carbonate, and sorbitan monostearate. and one or two types of sorbitan tristearate.

More specifically, the above mixture contains carnauba wax, ceresin, white beeswax,
The present invention can be applied by blending one or more types selected from the group of microcrystalline wax, sucrose fatty acid ester, solid paraffin, polyglycerin fatty acid ester, and saturated fatty acid glycerin. It is possible to obtain a makeup cosmetic that gives a smooth feel and a dry feel, has good makeup retention after application, and has high stability over time.

(Detailed Description of the Invention) As volatile oils that can be used as raw materials for cosmetics, low-boiling hydrocarbons, low-boiling isoparaffinic hydrocarbons, low-degree linear silicones, and low-degree cyclic silicones are known. However, among these, the first three are tetramers and pentamers among low-polymerization degree cyclic silicones, which are not suitable as volatile oils due to their odor and poor compatibility with waxes, oils, etc. The cyclic silicone (hereinafter abbreviated as cyclic silicone) is odorless and has good compatibility, so it is a superior volatile oil compared to the former three.

The volatile oil retaining components used in the present invention include:
Examples include sorbitan monostearate, sorbitan tristearate, silicic anhydride, and organic bentonite. Among these, sorbitan monostearate and sorbitan tristearate promote and improve the compatibility of cyclic silicone with other waxes and fats and oils, and also help adjust the oil phase and improve pigments.
It has excellent effects on wetting and dispersing properties of coloring materials such as titanium mica.

Silicic anhydride is a fine powder and is highly absorbent, and organic bentonite swells to form a network structure when propylene carbonate and soybean phospholipid are added, and both suppress the volatilization of the cyclic silicone.

Solidifying components include carnauba wax, ceresin, white beeswax, microcrystalline wax, sucrose fatty acid ester, solid paraffin, polyglycerin fatty acid ester 5-saturated fatty acid glycerin, and these have good mutual compatibility and stability over time. It is also a high component.

The desired volatile makeup cosmetic can be obtained by blending appropriate amounts of the above-mentioned cyclic silicone, retention component, and solidification component, but depending on the type and purpose of the makeup cosmetic, mineral oil, vegetable oil, Known ingredients for cosmetics, such as ester oil and silicone with a medium to high degree of polymerization, can also be blended as appropriate.

Furthermore, a make-up cosmetic can also be obtained by blending an appropriate amount of the mixture of the cyclic silicone and the retained component into a conventionally known cosmetic composition.

In addition, organic and inorganic pigments, titanium mica, extender pigments, nylon powder, etc., which are commonly used in cosmetics, are used as coloring materials.

The amount of each component used in the present invention and the reason for its limitation will be explained below.

The amount of cyclic silicone to be blended is in the range of 10 to 80% by weight based on the total composition of the cosmetic (hereinafter, % means % by weight), but more specifically, the amount of the cyclic silicone is Overall score of 25-7 for touch, feel, volatilization time, strength, etc.
0% is preferred.

If it is less than 10%, the touch and usability will deteriorate.
In addition, since the applied material evaporates quickly, the correction time after application is short, and the cosmetic effect is insufficient to satisfy the needs.
If the amount exceeds 10%, problems will arise in terms of anti-slip effect, strength, etc., so it is used within the above range. Silicic anhydride is 0
．． It is blended in a range of 1 to 10%. If it is less than 0.1%, the retention of the cyclic silicone will be poor, and if it is more than 10%, the viscosity will become high, making defoaming, molding, etc. difficult.

More specifically, a range of 0.5 to 8% is preferable.

Organic bentonite is blended in a range of 0.1 to 15%. If it is less than 0.1%, stability over time is poor;
If the amount exceeds 15%, stickiness, elongation, slippage, etc. will be poor, and the viscosity will become high, making defoaming, molding, etc. difficult. In consideration of touch, stability, moldability, etc., a range of 1 to 10% is preferable.

Propylene carbonate is blended in a range of 0.1 to 10%. If it is less than 0.1%, it is insufficient to swell the organic bentonite, while if it is more than 10%, the swelling effect remains the same, and more preferably in the range of 0.5 to 6%.

Soybean phospholipid is blended in a range of 0.1 to 10%.

If it is less than 0.1%, the wetting and dispersion effect of coloring materials such as pigments will be poor, and if it is more than 10%, the product will become sticky and the feeling of use will be poor.

A range of 0.15 to 6% is preferred.

Sorbitan monostearate and sorbitan tristearate are blended in a range of 1 to 20%. If it is less than 1%, the dispersion of coloring materials such as pigments, oil phase adjustment effect, strength, etc. will be weakened, and if it is more than 20%, the usability will be poor. More specifically, a range of 1.5 to 15% is preferable.

If carnauba wax is less than 1%, its strength will be weakened and it will break or chip, while if it is more than 40%, it will not be able to touch.
Since the feeling of use becomes poor, it is blended in a range of 1 to 40%, preferably in a range of 1.5 to 35%.

Ceresin and solid paraffin are blended in a range of 1 to 70%. If it is less than 1%, the strength will be weakened and 70
%, the creamy feel will be lost. Preferably it is in the range of 1.5 to 50%.

Microcrystalline wax is blended in a range of 1 to 70% because if it is less than 1%, the product will lack flexibility, and if it is more than 70%, the touch and feeling of use will be poor.

A range of 1.5 to 50% is preferred.

The blending amount of white beeswax can be in the range of 1 to 70%, and if it is less than 1%, the strength will be weak, while if it is more than 70%, the touch and feeling of use will be poor. Especially 1.5-5
A range of 0% is preferred.

Sucrose fatty acid ester and polyglycerin fatty acid ester are blended in a range of 1 to 70%. If it is less than 1%, the oil phase adjustment effect, strength, etc. will be weakened, and if it is more than 70%, the touch and usability will be poor. Preferably,
It is 1.5-50%.

The blending amount of saturated fatty acid glycerin can be in the range of 1 to 70%, and if it is less than 1%, the strength will be weakened, and 70%
%, the touch and usability deteriorate. More preferably, it is in the range of 1.5 to 60%.
