Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eye shadow, and more particularly to an eye shadow which is excellent in transparency, dotted feeling of pearl at the time of application, impact resistance and color retention effect.

[0002]

2. Description of the Related Art Conventionally, titanium / mica-based colored and white pearlescent agents have been blended in order to give eye shadows a variation in texture. However, pearlescent agents generally have poor moldability and it is difficult to mix them in high amounts. Therefore, it is usually used in combination with an extender pigment such as talc, kaolin, sericite, mica. However, although the moldability is improved by blending the extender pigment, the hardness becomes soft and the chips tend to come off, and the transparency of the pearlescent agent is lost due to the hiding power of the extender pigment. There was a tendency for the feeling of scatteredness to decrease. Further, since the pearlescent agent generally has a large oil absorption amount, the amount of oil required for molding also increases, so that “waviness” over time easily occurs. For the above reasons, it has been difficult to obtain an eye shadow base having good moldability and a high content of a pearlescent agent, and having a transparent and dotted feeling on the coated surface and having good color retention.

Means for Solving the Problems As a result of intensive studies made by the present inventors in view of the above problems, the inorganic value / organic value is 0.
The present invention has been accomplished by discovering that if one or more liquid oil components and a solid oil component are blended, an eye shadow having excellent moldability and excellent transparency can be obtained even if the pearlescent agent is highly blended. That is, the present invention is characterized by blending 60% by weight or more of a pearlescent agent with respect to the total amount, a liquid oil component having an inorganic value / organic value of 0.1 or more, and a solid oil component. Is.

The structure of the present invention will be described in detail below. The pearlescent agents used in the present invention include, in addition to ordinary mica titanium, iron oxide-treated mica titanium, iron oxide-treated mica, black iron oxide-treated mica titanium, iron oxide / black iron oxide-treated mica titanium, and carmine-treated mica titanium. , Carmine / Carbon Mica Titanium, Iron Oxide / Carmine Titanium Mica, Konjou Titanium Mica, Iron Oxide / Carbon Mica Titanium,
Examples include chromium oxide treated mica titanium and black titanium oxide treated mica titanium. The amount of pearlescent compound is 60 with respect to the total amount.
˜95 wt%, preferably 70-90 wt%. If it is less than 60% by weight, the pearly appearance is deteriorated and the amount of oil is relatively increased, so that the stickiness is felt, and further, the scattered feeling of pearls on the coated surface is reduced, and “wrinkling” occurs over time.
Cause If it exceeds 95% by weight, molding becomes impossible.

The liquid oil used in the present invention has an inorganic value / organic value of 0.1 or more, preferably 0.
It is 2 or more. With a liquid oil having an inorganic value / organic value of less than 0.1, a sufficient pearly feeling cannot be obtained. Here, the inorganicity value / organicity value is based on Minoru Fujita's organic conceptual diagram (Morning Fujita, Masami Akatsuka, Systematic Organic Qualitative Analysis (Mixtures))
1974, published by Kyoritsu Shuppan), inorganic value / organic value = ratio line = I. O. B (Inorganic Organic Balance) = ta
n α, which represents the polarity of the organic compound. The higher the number, the higher the polarity and the water becomes ∞. For liquid oils with an inorganic value / organic value of 0.1 or more, neopentyl glycol dicaprate (IOB = 0.25), diisopropyl sebacate (IOB = 0.40), isopropyl myristate (IOB = 0.18) ), Glycerin tri-2-ethylhexanoate (IOB = 0.36), pentaerythritol tetraoctanoate (IOB = 0.35), cetyl octanoate (IOB = 0.13), trimethylolpropane triisostearate ( Ester oil such as IOB = 0.20), olive oil (IOB = 0.16), vegetable oil such as castor oil (IOB = 0.42), isostearic acid (IOB = 0.43), oleic acid (IOB = 0.4
2) Fatty acids such as decyltetradecanol (IOB =
0.21), oleyl alcohol (IOB = 0.28)
Higher alcohol such as. The compounding amount is 5 to 20% by weight, preferably 8 to 15% by weight. If it is less than 5% by weight, the moldability will be poor, and if it exceeds 20% by weight, chipping will increase and the scattered feeling on the coated surface will disappear, and further, "wrinkle" will occur over time.

The solid oil used in the present invention includes oils and fats such as smelt, hydrogenated castor oil, waxes such as beeswax, carnauba wax, whale wax, candelilla wax, hard lanolin, and carbonization of paraffin, ceresin, microcrystalline wax and the like. Hydrogen, myristic acid, palmitic acid,
There are natural fatty acids such as stearic acid, behenic acid and 12-hydroxystearic acid. Hydrocarbons are preferred. The blending amount is 1/4 to 3 times the amount of the liquid oil, and preferably 1/2 to 2 times. If the amount is less than 1/4, the effect as a binder is insufficient, the moldability is deteriorated, the chips are often peeled off, and the scattered feeling on the coated surface is lost. If the amount exceeds 3 times, the effect is not improved so much and it is uneconomical.

The powder solid cosmetics of the present invention include other oils, powders other than pearlescent agents, hydrophobized powders, preservatives, surfactants, antioxidants, pharmaceuticals, and fragrances as long as the effects of the invention are not impaired. UV absorbers, moisturizers, etc. can be added.

Examples 2 to 5 and Comparative Examples 1 to 3 In the same manner as in Example 1, eye shadows were produced according to the formulations shown in Table 1 and Table 2.

The eye shadows of Examples and Comparative Examples were compared in terms of usability, dotted feeling of pearls on eyelids, color retention, and impact resistance. The data shown in Tables 1 and 2 are obtained by having 20 female panels apply eye shadows to the left and right eyelids and test the usability. The evaluation criteria are as follows. ◎: Very good ○: Good △: Bad ×: Very bad

The impact resistance was evaluated by a drop test from a height of 30 cm, and evaluated by how many times it dropped to break. The evaluation criteria are as follows. ◎: 11 times or more ○: 7 to 10 times △: 5 to 6 times ×: 4 times or less

As is clear from Table 1 and Table 2, the eye shadow of the present invention is very good in usability, dotted feeling of pearls on the eyelids, color retention and impact resistance as compared with the conventional products. I understand. In the table, the appropriate amount is 0.01 to 0.
The amount is in the range of 5% by weight.
