Description

Gel typed lip make up composition containing inorganic pigment with optically color variable properties}

The present invention relates to a lip makeup composition, and more particularly, various colors are observed according to the viewing angle by increasing the optical interference effect of the inorganic pigments when applied to the lips, thereby providing a unique makeup effect, as well as chromaticity and gloss. And a gel type lip makeup composition having excellent usability and good high temperature stability with little sweating.

Lipsticks generally consist of waxes and oils and pigments such as inorganic pigments used to impart a beautiful color to the lips.

Among the inorganic pigments, inorganic pigments are coated with an opaque reflector such as aluminum or iron oxide coated with a plate-like silica substrate which is easy to transmit light so that various colors can be observed depending on the viewing angle to give a unique cosmetic effect. Inorganic pigments that cause such optical color change have excellent light interference effect and show various colors from red to yellow-green or red-yellow-green to reddish purple to yellow or blue depending on the viewing angle. However, when the inorganic pigment causing the optical color change is applied to a conventional lipstick composition as it is, it is difficult to express a vivid color due to the wax component contained in the composition, there is a problem that the effect of the color change due to light interference is significantly reduced. In addition, in order to impart high temperature stability to the product, a large amount of the wax component has to be used, and thus there is a limit in showing a soft feeling, and since a wax and oil are used in combination, sweating occurs when the oil is separated at a high temperature.

In order to solve these problems due to the use of wax, Japanese Laid-Open Patent Publication No. 9-235210 discloses a solid cosmetic with improved gloss containing dextrin fatty acid ester, heavy liquid isoparaffin and microcrystalline wax. However, although solid cosmetics such as stick-like lipsticks are effective in improving glossiness, the effect of color change due to light interference of inorganic pigments causing optical color change is reduced by adding microcrystalline wax into the lipstick. There is not enough color clarity or feel.

Therefore, the technical problem to be achieved by the present invention is to solve the above problems by applying various colors to the viewing angle by increasing the optical interference effect of the inorganic pigment when applied to the lips, not only give a unique makeup effect, but also sufficient color, gloss And it is to provide a lip makeup composition of the gel type having a very good feeling and good high temperature stability with almost no sweating.

In order to achieve the above object, the present invention, in the lip makeup composition, 0.1 to 20 parts by weight of an inorganic pigment, a silica coating layer and iron oxide coating layer sequentially formed on a substrate made of iron oxide or aluminum, 1 to 20 parts by weight of dextrin fatty acid ester It provides a gel type lip makeup composition comprising 20 to 80 parts by weight of an ester liquid oil, 0.1 to 20 parts by weight of dimethicone and 1 to 50 parts by weight of polybutene.

Hereinafter, the gel type lip makeup composition of the present invention will be described in detail.

As the inorganic pigment causing the optical color change contained in the lip makeup composition according to the present invention, as shown in Figure 1, the optical interference effect on the substrate (1, 4) made of iron oxide (Fe ₂ O ₃ ) or aluminum as an opaque reflector It is coated with a silica (SiO ₂ ) coating layer (2) which is excellent but easily permeable to light, and a iron oxide (Fe ₂ O ₃ ) coating layer (3) which is an opaque reflector. The light 5 incident on the inorganic pigment is partially reflected and partially transmitted by the iron oxide coating layer 3 which is an opaque reflector. Since some of the transmitted light is transmitted through the silica coating layer 2 and reflected back from the base materials 1 and 4 made of iron oxide or aluminum, the light interference effect is excellent. Therefore, depending on the viewing angle, various colors ranging from reddish-purple to yellow-red or blue to red-yellow-green give a unique makeup effect to the lips. The inorganic pigments of FIGS. 1A and 1B may be used alone or in combination, respectively. The size of the inorganic pigment and the thickness of each coating layer can be adjusted within a range that does not impair the object of the present invention, as well as a plate inorganic pigment, as well as spherical inorganic pigments can be used as illustrated in FIG. .

The content of the inorganic pigment causing the optical color change contained in the lip makeup composition according to the present invention is 0.1 to 20 parts by weight. If the content is less than 0.1 parts by weight, the color change effect is not sufficient. Usability of city becomes heavy.

The dextrin fatty acid ester contained in the lip makeup composition according to the present invention not only maintains the stability of the product by imparting oil stabilization and high temperature stability, but also enhances the optical interference effect of the inorganic pigment by imparting transparency that cannot be expected when using conventional waxes. It shows optical color change and vivid chromaticity. In addition, when applying the lip makeup composition to the lips, it gives a soft feeling and adhesion and gloss effect. Dextrin fatty acid esters represented by the following formula (1) include dextrin palmitate, dextrin stearate, dextrin behenate, and the like, and these may be used alone or in combination.

In Formula 1, A is C ₁₅ H ₃₁ CO, C ₁₇ H ₃₅ CO, C ₂₁ H ₄₃ CO or H.

The content of the dextrin fatty acid ester contained in the lip makeup composition according to the present invention is 1 to 20 parts by weight. If the content is less than 1 part by weight, the oil stability and temperature stability are not sufficient. Degrades.

The lip makeup composition according to the present invention contains an ester liquid oil which is liquid at room temperature (25 ° C.) and excellent in compatibility with dextrin fatty acid ester in order to impart a softening effect. It is preferable to use an oil having 17 to 38 carbon atoms as the ester liquid oil. Ointment oils such as pizza horse oil, dipentaerythryl ester, lanolin, and petroleum jelly are not preferable because they have problems with compatibility with dextrin fatty acid esters and impair the transparency of the product, resulting in poor color clarity. The content of the liquid oil contained in the lip makeup composition according to the present invention is 20 to 80 parts by weight, but if the content is less than 20 parts by weight, not enough flexibility is given, it is not easy to manufacture, and if it exceeds 80 parts by weight, Hard to give hardness.

In the lip makeup composition according to the present invention, 1 to 50 parts by weight of polybutene is added to give sufficient gloss. If the content is less than 1 part by weight, it is difficult to give sufficient glossiness. If the content exceeds 50 parts by weight, it is sticky and the feeling of use is lowered.

In addition, since the dextrin fatty acid ester and the polybutene component contained in the lip makeup composition according to the present invention have a function of stabilizing bubbles generated during manufacture, the bubbles must be effectively suppressed and defoamed in order to improve product quality. To this end, the lip makeup composition according to the present invention contains 0.1 to 20 parts by weight of dimethicone, but if the content is less than 0.1 parts by weight, it is difficult to obtain a degassing effect. .

As such, the gel type lip makeup composition prepared with an ester liquid oil, dextrin fatty acid ester, dimethicone, polybutene, and an inorganic pigment causing optical color change in the content according to the present invention includes a conventional lipstick containing a wax component and In contrast, the color clarity, high temperature stability and gloss is excellent, exhibits a soft feeling of use, and gives a unique lip makeup effect that changes color depending on the viewing angle by increasing the optical interference effect of the inorganic pigment. To the makeup composition of the present invention, various substances, for example, pigments, sunscreens, discoloration inhibitors, antioxidants, and the like, can be appropriately added to the extent not impairing the object of the present invention.
