Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a cosmetic product which is formulated with a powder having an iridescent luster, has a beautiful appearance, and can also provide make-up and makeup effects depending on the purpose. 0 Conventionally, cosmetics often contain Burl pigments along with various pigments and coloring materials, providing consumers with beautiful color tones and glossy shine.

Although there are various types of Burr pigments, they all have the following drawbacks, and are not necessarily satisfactory for use in cosmetics.

For example, natural fish scale foil has an elegant and uniform burl luster, but since the main component is guanine, which is J'l: +45 from the fish body (ifj, extremely high (ll
li, and since it is a natural product, weather and fish σ)
There are many variations in quality, such as gloss often decreasing due to metabolic abnormalities, etc., and this has been a source of concern for cosmetic engineers who are trying to stably provide consumers with cosmetics that have a burl luster.

Bismuth chloride and basic lead carbonate are also known as Burr pigments, but have good lightfastness and safety. It is a well-known fact that there are problems with this, making it undesirable to include it in cosmetics.

Mica-titanium thread/glass pigments are inexpensive, have no safety problems, and are available in a variety of average particle sizes, so they are widely incorporated into cosmetics depending on the desired bar gloss. However, this material has an average major axis of 2 to 100 microns and an average thickness of 0.03 to 1 micron, and has a wide range of particle diameters, and is not necessarily satisfactory in terms of gloss, such as good gloss and uniformity. It wasn't.

In view of these circumstances, the inventors of the present invention have conducted extensive research to resolve the drawbacks of the conventional Burl pigments, and as a result, created a resin layer containing an alkyl metal compound on the surface of a thin metal layer to produce iris color. Furthermore, the iris-colored powder that has been crushed into a predetermined size is an excellent pearl powder that does not have the above-mentioned drawbacks, and this product can be used for makeup. It was discovered that when the present invention is blended into a cosmetic, preferably a transparent cosmetic, a highly safe cosmetic that exhibits a burl luster with a unique iris color can be obtained, and based on this knowledge, the present invention was completed. Ta.

That is, the present invention provides a cosmetic composition that includes a thin layer of metal, a thin layer of a mixture of an alkyl metal compound and a synthetic or natural resin on both sides of the thin metal layer, and a combination of two of the mixtures. This is a cosmetic with special characteristics.

In particular, in the present invention, by blending the iris-colored powder of the present invention into cosmetics that have a transparent appearance, it exhibits pearlescent luster with a unique iris color not found in conventional Burr pigments.

In addition, the iris-colored powder according to the present invention can provide iris-colored burl luster without using dyes or pigments;
It is also advantageous in terms of safety and light resistance, which are also features not found in conventional Burr pigments.

(Hereinafter, blank space) In the present invention, the cosmetics to which the above-mentioned iris-colored powder should be blended are:
It can be oil-based, water-based, solubilized, emulsified, powdered, or powder-based, but in order to make more effective use of the pearlescent luster that has iris color, cosmetics G.
J. It is preferable to use a material that has a transparent appearance.

Next, the iris-colored powder used in the present invention will be explained in detail.

FIG. 1 of the accompanying drawings shows the five-layer laminated structure of the present invention.
FIG. 2 is a schematic diagram of a laminated structure of iris-colored powder.

In FIG. 1, l is a thin metal layer, usually an aluminum, silver or copper foil of 5 to 7 microns, preferably 5 to 7 microns. A layer 2.2' of an alkyl metal compound-resin mixture is provided on both sides of the metal foil 1. Examples of alkyl metal compounds used are argyl titanates, 9tetra-n-butoxyzirconium and tetra-isopropoxyzirconium, such as tetra-n-butoxytitanium, tetraisopropoxybutane, tetraethylhexoxytitanium, tetrastearoxytitanium, etc. Alkyl zirconates such as; alkyl silicates such as tetra-n-butoxysilane; alkyl germanates such as tetra-n-butoxygermanium and tetraisoprooxygermanium; and alkyl aluminates such as tetraisobutoxyaluminum, etc. One kind or a mixture of two or more kinds of these compounds can be used. Alkyl titanates are preferred, and rapidly hydrolyzed compounds such as tetrapropoquine titanium and tetra-n-butoxytitanium are more preferred.

Examples of resins used in combination with the above alkyl metal compounds are natural resins, petroleum resins, terpene resins, ketone resins,
Phenol resins, polyamide resins, epoxy resins, melamine resins, alkylene resins, resins, fats, urethane-modified acrylics that can be cured by infrared rays, polyester-modified acrylic resins, styrene-modified acrylic resins, epoxy-modified acrylic resins, etc. , one or a mixture of two or more of these can be used.

The alkyl metal compound-resin mixture layer contains 2 to 0.05 parts of resin, preferably 1 to 1 part by weight of the alkyl metal compound.
O11 can be easily provided by applying a more preferably 0.5 to 0.1 part by weight solvent solution onto both sides of the metal foil. Any solvent commonly used as a solvent for aromatic hydrocarbons such as toluene, esters such as ethyl acetate, ketones such as methyl ethyl ketone, and resins can be used. The dissolved concentration of the alkyl metal compound-resin mixture in the solution is 30 to 70%, preferably 40 to 6o%.
It is good to be.

(Hereinafter, blank space) Application of the solution can be carried out using any known coating machine such as a roll coater, but usually 150 to 30
A gravure printing machine of 0 mils per inch width is used.

When using a roll coater, the layer 2 has a substantially uniform thickness.
However, using a gravure printing machine, it is possible to form a layer 2 with a non-uniform thickness due to the unevenness of the plate surface, and due to this non-uniform thickness, the final product has a highly variable iris color. present. A printing plate with a deep engraved or etched surface provides a greater variety of iris colors, and plates with patterns such as stripes, checkers, dots, swirls, etc. give better results.

The thickness of layer 2 is 2000 to 9 if the layer is uniform in thickness.
000 angstroms, preferably 3000 to 75
00 angstroms.

In the case of gravure printing, the amount of coating is determined by the number of meshes and the depth of engraving, and the amount of coating after drying is 0.2~
09 grams, preferably 03-08 grams.

Metal semi-thermal bonding layers 3, 3' are provided on the surfaces of the two layers 2, 2' of the alkyl metal compound-resin mixture formed on both sides of the metal foil that are not in contact with the metal foil as described above. .

The thickness of the semi-thermal bonding layer is 100 angstroms or more and less than 400 angstroms, preferably 200 to 300 angstroms.
Angstrom.

The raw fish coat 1'V 3,3' is usually formed by vapor deposition of aluminum, silver or copper, which may be the same or different metal than the central layer.

] The metal foil layer forming the center layer of the five-layered film can also be a layer of vapor-deposited metal.In this case, a supporting film is used, and this supporting film is
A method is adopted in which layers 4 are sequentially formed one layer at a time.

FIG. 2 is a schematic diagram showing a state in which a five-layer laminated film is formed on a support film in a method in which the above-mentioned support film is used.

In FIG. 2, 4 is a support film, on one side of which a semi-thermal bonding layer 3 of metal is formed by vapor deposition, and on top of the semi-thermal bonding layer 3, an alkyl substance-resin mixture layer 2 is further formed. As in the case of FIG. 1, the metal layer 1 is provided by evaporation.

In this case, the deposition thickness is 400-800 angstroms, preferably 400-600 angstroms.

Similarly, alkyl metal-resin mixture J・42′,
After sequentially providing the metal half-covering layer 1', the supporting layer 4 is peeled off, and 5
Thin films with layered iris colors can be obtained.

The supporting film can be any film commonly used for supporting polyester films, such as polyethylene terephthalate films, polypropylene films, or polyethylene films '4, 717, with a semi-thermal adhesive layer pre-prepared on the side to be deposited. It is preferable to apply a release agent using a gravure printing machine or a reverse roll tool.

Any known mold release agent such as polyvinyl acetate with a low degree of polymerization, acrylic resin with a low degree of polymerization, etc. can be used.

It is then ground into powder to the desired particle size. Grinding can be done using any grinder. After this, it may be sieved if necessary.

The particle size of the iris-colored powder obtained by pulverization varies depending on the purpose, the crowbar at the bottom, and the feeling of use, but it is usually 0.005 m.
m~1. It is in the range of 0 mm. Further, the amount to be added to cosmetics is arbitrary as in the case of conventional pearl pigments, but it is preferably 05 to 50% by weight.

The iris-colored powder according to the present invention has a beautiful iris color due to the interference of light, and the iris color does not fade over a long period of time and is safe for the human body, and cosmetics containing this powder have a particularly transparent appearance. A pearlescent luster with an iris color of German X can be obtained in a cosmetic with 11-temperature, and it is a cosmetic with excellent stability and safety.

Cosmetics obtained by the present invention include makeup cosmetics such as eye shadows, lipsticks, nail enamels, water-based nail enamels, foundations, whitening powders, foundations such as powders, creams, milky lotions, lotions, and soaps. There are a wide variety of cosmetics, including hair, body, and aromatic cosmetics such as hair lotion dusting powder, body lotion, and line perfume. You can get expensive cosmetics. In particular, when the iris-colored powder is blended into a cosmetic with a transparent appearance, 1. This cannot be obtained by simply blending the iris-colored powder into a cosmetic, and it cannot be obtained at all by blending conventional pearl pigments. It is possible to obtain a new beautiful cosmetic material that has an iridescent pearlescent luster with a sense of transparency that was previously impossible. In addition, since the iris-colored powder according to the present invention has a lighter specific gravity than conventional pearl pigments, there is less need to thicken cosmetics, and in this sense, the scope of use of the present invention for cosmetics is limited.
