Abstract

PURPOSE:A solid make-up cosmetic that is made by adding an appropriate amount of mica whose crystal water is removed to pearl pigments and the oil base, thus showing high impact strength in spite of high content of the pearl pigments and causing no caking while used. CONSTITUTION:The objective solid make-up cosmetic is made by adding 5- 60wt% of mica whose crystal water is removed by heating or vacuum deaeration to 30-80wt% of pearl pigments such as of titanium-mica or titanium-inorganic pigments-mica along with 10-35wt% of oil such as olive oil, lanolin or squalane. The resultant cosmetic can freely contain a wide range in amounts of the pearl pigments so that the largest make-up effect can be developed according to the purposes of individual products.

Description

Detailed Description of the Invention: Although the present invention contains a large amount of pearl pigment, it has strong impact resistance, and even when used, it does not caking (the surface has an oily shine), and the cosmetics can be used on cosmetic puffs, brushes, and tips. This invention relates to solid makeup cosmetics that do not cause problems such as inability to be removed.

In recent years, pearl pigment production technology has made remarkable progress, and a variety of beautiful pearl pigments are now on the market.

However, traditional solid makeup.

In cosmetics, large amounts of bar pigments have been blended. In order to compensate for this, the amount of oil that acts as a binder was reduced, which caused a big problem in actual use.

In other words, although there has been a strong desire for solid makeup cosmetics containing a large amount of pearl pigments from the viewpoint of makeup effects, it has not been possible to obtain products that can be supplied to the market. Ta.

In order to improve these drawbacks, the present inventors conducted a huge number of experiments on various powder combinations, oil content combinations, and amounts of each component. The inventors have discovered that it is possible to incorporate a large amount of oil without fear of causing caking, and based on this knowledge they have completed the present invention.

That is, the present invention contains 5 to 60% by weight of mica obtained by dehydrating crystallization water, 30 to 80% by weight of Burl pigment, and 10 to 3% by weight of oil.
The object of the present invention is to provide a solid makeup cosmetic characterized in that it contains 5% by weight.

The configuration of the present invention will be explained in detail below.

Conventionally, clay minerals such as mica contain water of crystallization in their structures, but the mica that has been dehydrated from water of crystallization used in the present invention is one that has been dehydrated from water of crystallization by heating or vacuum degassing81. When dehydrating by I0 heating, it is necessary to treat it at a temperature of 700"C or more for 2 hours or more, but at that time, it is possible to dehydrate it at the raw ore stage and then crush it, or to dehydrate it after crushing it. It may be processed.

Dehydration of clay minerals generally reduces the adhesion of powders based on water of crystallization, but the same holds true for mica, and the adhesion decreases as the processing temperature increases.

As is clear from FIG. 11, when the treatment temperature is 700° C. or higher, the adhesion of the powder is significantly reduced, and this confirms that the water of crystallization in the mica is dehydrated.

(11th ffl) The influence of heat treatment on the adhesion of mica powder is shown. The treatment time was measured at any temperature using a powder adhesion measuring device ED-2, ooo-07 manufactured by Oi.

The amount of mica that has been dehydrated from crystal water is 5 to 60% by weight based on the weight of the cosmetic. If it is less than 5% by weight, caking will occur; if it is more than 60% by weight, it will not be possible to incorporate a large amount of pearl pigment due to the formulation structure, so there will be no advantage. Dehydrated mica must have an oil content of 50% or more by weight.

If the amount of dehydrated mica is less than this, the anti-caking effect will not be exhibited.

(The following is a blank space) The pearl pigments used in the present invention are pearl pigments such as titanium-mica thread, titanium-inorganic pigment-mica system, titanium-organic pigment-mica system, and titanium-inorganic pigment-organic pigment-mica system. The amount of compounding ingredients is 30 to 30% based on the weight of the composition.
Weight at 80% weight. If it is 30% or less, it can be manufactured using conventional technology.

80% or more by weight cannot be added due to the composition of the prescription.

The oils used in the present invention include various vegetable oils, animal oils, mineral oils, and synthetic oils commonly used in cosmetics. Examples include olive oil, lanolin, liquid paraffin, squalane, silicone oil, and various ester oils. When the ingredients runny, oil may bleed onto the surface of the cosmetic, or the contents may become smudged when removed with a puff, brush, or tip, which is not practical.

Naturally, the makeup cosmetics according to the invention include raw materials normally used in cosmetics, such as surfactants,
It is also possible to incorporate fragrances, preservatives, antioxidants, pigments, etc.

Although the solid makeup cosmetic of the present invention contains a large amount of temporary pearl pigment, it has good impact resistance and does not cause caking, so it can be tailored to the purpose of each individual product. This cosmetic product has been long awaited in the market because it allows the user to freely mix in the amount of pearl pigment that maximizes the makeup effect.

(Margin below) Table 1 (Unit: double weight %) (Manufacturing method) The powder part is stirred and mixed in a blender, and the oil part (aO ~ 90''C) containing preheated and dissolved preservatives and fragrance are sprayed and further stirred. After that, it is crushed and molded using a molding machine to obtain a powder eye shadow.
After dropping into L, the state of cracks, cracks, and chips was observed.

○...All 10 pieces have no cracks, cracks, or chips.

△...More than 5 out of 10 items have cracks and chips.

×... More than 5 out of 10 pieces broke and shattered〇(
Evaluation of caking) Eye shadow was removed by rubbing the surface with a cosmetic tip that faces toward the male side.

○・・・・・・It is in good condition until the end.

△・・・・・・You can take it all the way to the end, but some of it will be caked.

×・・・・・・Caking occurs at the beginning of use and cannot be removed.

(Evaluation of usability) A practical use test was conducted using a sensory panel 1.04, and the spreadability, stickiness, and ease of blurring were expressed as average values.

○・・・・・・Good spread, stickiness, and ease of blurring.

Δ: Slightly good spreadability, adhesion, and ease of blurring.

×...Does not spread well and is difficult to blur.

Examples in Table 1] and 2.3 used calcined mica whose crystallization water was dehydrated at 700°C. Izune's Example, which is an example of a powder eyeshadow formulation, also has strong impact resistance, removes well with chips, and does not cause caking.

Furthermore, in terms of usability, it exhibited aspects not found in conventional mica, with excellent spreadability, stickiness, and ease of blurring. Of course, the brightening effect based on the combination of a large amount of pearl pigment was much better than that of conventional formulations.

Comparative Examples 1, 2, and 3 in Table 1 are those in which the fired mica of the example was replaced with the conventional mica.
