Abstract

PURPOSE:To provide the titled cosmetic obtained by compounding a specific amount of powdery agglomerate having a specific particle diameter to a cosmetic, and capable of controlling the color on the skin according to the rubbing force and rubbing times in the application to the skin. CONSTITUTION:Powder having particle diameter of 0.01-50mu and selected from an extender pigment such as talc, mica, zinc white, kaolin, etc. and a color pigment such as titanium dioxide, iron oxide, sintered pigment, organic pigment, etc., is granulated by using a fluid oil, semisolid oil or solid oil of animal, vegetable, mineral or synthetic origin to obtain powder agglomerate having particle diameter of <=200mu. The agglomerate is added to powdery make-up cosmetic in an amount of 0.1-70wt% based on the whole cosmetic.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to powder makeup cosmetics such as eye shadow, pink powder, and white powder. For more details, particle size 200μ
The present invention relates to a makeup cosmetic which is characterized by containing the following powder aggregates and whose applied color can be controlled by applying force when applying to the skin and by increasing or decreasing the number of times of application.

[Prior Art] Conventional makeup cosmetics are manufactured to exhibit a single application color determined by a combination of pigments.

For this reason, it has been necessary to prepare a large number of color tones in order to match the complexion and preferences of consumers. Also,
From the consumer's point of view, when the color of the skin changes due to sunburn, for example, there is a drawback that makeup cosmetics of a different tone must be sought each time.

[Problems to be Solved by the Invention] In view of the above circumstances, the present inventors believe that consumers can
Or, as a result of intensive research with the aim of creating a cosmetic that allows you to enjoy makeup by freely changing the applied color for each part of the face, we have found that by blending powder agglomerates into a powder no-cap cosmetic, we have achieved the above objectives. The present invention has been completed based on the discovery that it is possible to accomplish the following.

[Means for Solving the Problems] That is, the present invention is a powder makeup cosmetic characterized by containing 0.1 to 70% by weight of powder aggregates having a particle size of 200 μm or less.

Hereinafter, the configuration of the present invention will be explained in detail.

The powder agglomerates of the present invention are obtained by granulating the powder with a suitable oil.

The powders used include extender pigments such as talc, mica, titanium mica, zinc white, kaolin, silicic acid, and resin powder, and colored pigments such as titanium dioxide, iron oxide, ultramarine blue, sintered pigments, and organic pigments. The particle size of these powders is generally about 0.01 to 50 μm, but in the present invention, they are granulated to form powder aggregates with a particle size of 200 μm or less.
If it exceeds 200μ, the appearance of the powder makeup cosmetic becomes non-uniform (that is, powder aggregates become visible to the naked eye), which is not preferable.

The oils used for powder granulation include liquid paraffin, squalane, petrolatum, microcrystalline wax, osikelite, hydrocarbons such as ceresin, higher fatty acids such as myristic acid, palmitic acid, stearic acid, oleic acid, and isostearic acid, cetyl alcohol, Higher alcohols such as hexadecyl alcohol and oleyl alcohol,
2-octyl dodecyl myristate, neopentyl glycol 2-ethyl hexanate, inoctylic acid triglyceride, 2-octyl dodecyl oleate, isopropyl myristate, jojoba oil, isostearic acid triglyceride, avocado oil, beeswax, myristyl myristate, mink oil, lanolin, etc. Four types are selected from animal, vegetable, mineral, synthetic fluid oils such as various ester oils and silicone oils, semi-solid cedar oil, and solid oils. One type may be used or two or more types may be used in combination.Of course, if solid oil is used for granulation, powder aggregates that are more difficult to break than those using fluid oil will be produced. This allows you to control how the color appears due to destruction.

Granulation may be performed according to a generally known method. For example, granulation may be performed using a Henschel mixer, a flow coater, or the like.

The content of oil in the powder agglomerates is 0.5-99% by weight, the remainder being powder.

The powder agglomerate thus obtained is incorporated into a powder makeup cosmetic base. One type of powder aggregate may be blended, or two or more types may be blended.

Also, if the oil used for granulation is a solid oil, it is better to heat it to a molten state, granulate it, mix it into a powder makeup cosmetic base at that temperature, and sprinkle it on the base powder. preferable.

Powder makeup cosmetic base is composed of powder,
Oil and surfactant are added to this as necessary.

When blending the powdered cosmetic into the powdered makeup cosmetic base, it is important to be careful not to destroy the powder aggregates due to the stirring force during mixing.

The color of the powder makeup cosmetic base is toned to be darker or lighter than that of the powder aggregate, but if the difference is not extreme, the makeup will look more natural. The type and content of the powder constituting the powder aggregate and the powder makeup cosmetic base are free, and may be completely different or partially the same.

The blending amount of the powder aggregate in the total amount of the powder makeup cosmetic is in the range of 0.1 to 70% by weight.

If it is less than 0.1%, even if the powder aggregates are completely destroyed when applied, the color change effect on the color of the powder makeup cosmetic base will be small, and if it is more than 70%, the color tone of the powder aggregates themselves will change. This makes it difficult to achieve the novel effect of changing color by applying the present invention.

Powder makeup cosmetics containing powder agglomerates can be left loose or compressed to form solid powder cosmetics. Normal compression molding pressures do not destroy the powder agglomerates.

In addition to the above-mentioned essential components, the powder makeup cosmetic of the present invention may contain fragrances, antioxidants, ultraviolet absorbers, preservatives, and antifungal agents within a qualitative and quantitative range that does not impair the effects of the present invention. I can do it.

[Effects of the Invention] The powder make-up cosmetic composition of the present invention is a powder make-up cosmetic composition whose applied color can be freely controlled by applying force at the time of application or by varying the number of times of rubbing. By blending multiple powder aggregates and making them different in their resistance to breakage, you can enjoy even more complex color changes. In the case of makeup cosmetics such as eye shadows that are used on a small part of the face, it is possible to make the color of powder aggregates remain as streaks, making it possible to produce playful makeup cosmetics. Is possible.
