Description

Color cosmetic composition having superior color expression property

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color cosmetic composition having excellent color expressive power, and more particularly, to a cosmetic composition capable of improving color expressive power when applied to skin surroundings by blending alumina powder into a cosmetic for color cosmetics.

Conventional color cosmetics are composed of powder, oil, and water, and they are face powder, compact, powder foundation, two-way cake, makeup base, liquid foundation, and cream foundation. (Base Makeup) and eye makeup, powder blush, lipstick, eyeliner, mascara, etc. It can be divided into point makeup.

In general, these products are applied to the skin to hide flaws such as blemishes and blemishes, or to give natural and bright skin expression or shade by color to make the face appear three-dimensional. The color that appears when applied to the face in point makeup and base makeup products is one of the most important factors in determining the quality of color cosmetics. In particular, the point makeup that shades the face uses a mixture of white pigments such as talc and mica, and inorganic and organic pigments. However, there is a lot of difficulty in matching the appearance color and the expression color without artificial feeling by mixing inorganic, organic pigments and white pigments, and this unnaturalness is one of the complaints of women currently using color cosmetics.

In order to solve this problem, Korean Patent Laid-Open Publication No. 2002-0005316 tried to improve the natural and color expression by coating an alkyl-modified silicone and an olive derivative on a cosmetic pigment with a high visible light transmittance, but the visible light transmittance In point makeup products that use a lot of low inorganic, organic, titanium oxide, etc., the application was somewhat difficult.

In order to solve the problems of the prior art as described above, an object of the present invention is to provide a color cosmetic composition excellent in color expression when applied to a point makeup product, as well as base makeup.

In order to achieve the above object, the present invention provides a color cosmetic composition comprising a powder, oil, and waxes, the alpha alumina powder in an amount of 0.01-50 parts by weight based on the total composition.

Hereinafter, the present invention will be described in detail.

The present inventors, while trying to develop a natural cosmetic similar to the external and expressive color in the color cosmetics, focusing on ruby and sapphire that is glossy, transparent and well-expressed color, the alumina which is the main component of ruby and sapphire to the color cosmetics It was used. The alumina can be industrially heated to 300 or less aluminum hydroxide to obtain pure alumina containing almost no impurities, which is alpha alumina.

Natural alumina varies in color from colorless to purple and is a hexagonal plate-shaped single crystal system. Therefore, since there are few large crystals with uniform color, it is possible to express colors in which the external color and the expression color coincide in the addition of organic and inorganic pigments having a constant color depth.

Alpha alumina used in the present invention is preferably an average particle diameter of 2 to 4 ㎛. At this time, if the average particle diameter of the alpha alumina is less than 2 μm, there is a problem of stiff feeling, and if it exceeds 4 μm, the surface is roughened.

The content of the alpha alumina can be determined in a range that shows a natural and bright color and maintains the formulation of the color cosmetic. Preferably, the content of alpha alumina is different depending on the color cosmetic product, but can be used in the range of 0.01 to 50 parts by weight based on the total composition, more preferably when used in 5-30 parts by weight shows an excellent color improvement effect. When the alpha alumina content is less than 0.01 parts by weight, the desired color improvement effect does not appear, and when it exceeds 50 parts by weight, problems in use and formulation occur.

In the method for producing a color cosmetic according to the present invention, alpha alumina is mixed with powder parts such as titanium dioxide, pigments and pearls together with other plate-like pigments and uniformly mixed, and then mixed with these powder parts with oils, waxes, etc., respectively. Tone cosmetics of the desired formulation are prepared.

The content of powders, oils, and waxes used in preparing the color cosmetics may be used in a well-known amount to those skilled in the art and is not particularly limited, and may further include additives such as flavors, preservatives, and the like, as necessary. can do.

The powder can be used as long as it is used in ordinary cosmetics, the type is not particularly limited, for example, talc, mica, silicon-coated talc, silicon-coated mica, sericite, gold mica, Barium sulfate, kaolin, boron nitride, mica titanium, fluorine apatite, hydroxy apatite, magnesium carbonate, calcium carbonate, titanium dioxide, silica, iron oxide pigments, pearl, etc., and these may be used alone or in combination of two or more thereof. .

The oil is preferably a silicone-based oil, and examples thereof include, but are not limited to, dimethyl polysiloxane, squalane, ester oil, and the like.

The color cosmetics include a base makeup such as face powder, compact, powder foundation, two-way cake, makeup base, liquid foundation, cream foundation, eye makeup, powder blush, lipstick, eyeliner, mascara, etc. It may be one of point makeup.

In addition, the color cosmetics of this invention can use the fragrance | flavor used normally, additives, etc. as needed. In the present invention, the process for manufacturing the color cosmetics, such as the face powder, compact, etc. are well known in the art, so the detailed description thereof is omitted, but it is easily understood by those in the art. .

Hereinafter, preferred examples are provided to help understanding of the present invention. However, the following examples are provided only to make the present invention easier, and the present invention is not limited to the examples.

(Example 1)

After mixing and pulverizing the composition components 1 to 8 once with a pulverizer in the content of Table 1, followed by secondary mixing with a Henschel mixer for 5 minutes at 1000 rpm, and heating and dissolving the components 9 to 11 again, this sample was again sprayed. Was mixed at 1000 rpm for 2 minutes. The eye shadow was then prepared by solidifying at a pressure of 20 Kgf / cm 2. In this case, the alpha alumina used in the present example was a product of Japan YKK Co., Ltd., in which 97% alumina and 3% alkylsilane were added.

(Example 2)

An eye shadow was prepared in the same manner as in Example 1, except that the content of the alpha alumina powder was different.

(Comparative Example 1)

An eye shadow was prepared in the same manner as in Example 1, except that alpha alumina powder was not used.

Note) In Table 1, silicon-coated talc was purchased from Korea Synthetic Pearl Industrial Co., Ltd. and silicon-coated mica was Si2 Mica MK 100 purchased from Korea Synthetic Pearl Industrial Co., Ltd.

In the case of using alpha alumina, a blind test was carried out on the products prepared in Examples 1, 2 and Comparative Example 1 using 42 women aged 20 to 50 years to test the color expression power and the feeling of makeup during eye makeup. Was carried out and the sensory evaluation and feeling during eye makeup, and the results are shown in Table 2. The evaluation criteria of Table 2 are as follows, and each value was shown by the statistical process.

(Evaluation standard)

5: very good, 4: excellent, 3: normal, 2: bad, 1: very bad

According to the above Table 2, Examples 1 and 2 of the present invention was evaluated to be excellent in color expressive power, and the feeling of pearl felt during makeup compared to Comparative Example 1. This is because the color expressive power is lowered by the comparative example compared with the Example with the fall of the reflectance of a pigment particle, and the fall of light scattering ability.

The color cosmetic composition comprising the alpha alumina powder of the present invention is applied to the skin, while maintaining the product feel of the same as conventional, while hiding the defects such as blemishes and blemishes or by giving a natural bright color expression or shade by color, The improvement effect on expressive power is excellent.
