Abstract

PURPOSE:A cosmetic having pearly luster, prepared by incorporating a transparent cosmetic base with plate polymeric powder laid in the form of many layers, and having a unique opaline pearly luster, and suppliable stably at a low cost without the variation in quality. CONSTITUTION:A cosmetic obtained by incorporating a transparent cosmetic base, e.g. transparent oil, transparent aqueous mixture, transparent solubilized material, transparent emulsified material, transparent powdery or transparent powder dispersion material, having >=30% transparency with 0.5-50wt% plate polymeric powder laid in many layers. The multi-layered plate polymer is prepared by laying two or more kinds of homo- or copolymer of polyester, polystyrene, acrylic resin, polyolefin or polyvinyl acetate, in 100-300 layers to give 10-50mu thickness, finely cutting the multilayered polymer by punching on a vacuum plate, etc. to form powder having 0.05-1.0mm. major and minor axes. The resultant cosmetic has high safety.

Description

[Detailed Description of the Invention] The present invention relates to a cosmetic that has a pearl-like luster, has a beautiful appearance, and is capable of imparting a make-up effect depending on the purpose. Pearl pigments are often blended with pigments and colorants, providing consumers with beautiful tones and glossy shine.

There are various types of pearl pigments, but all of them have the following disadvantages, and are not necessarily satisfactory for use in cosmetics.For example, natural fish scale foil has an elegant and uniform color. It has a pearlescent luster, but it is extremely expensive because its main component is guanine collected from fish bodies, and since it is a natural product, its luster often decreases due to weather or metabolic abnormalities in the fish. There were many variations in quality, and this was a source of trouble for cosmetic engineers who were trying to stably provide consumers with cosmetics with a bright shine. Although it is known as a monochrome pigment, it is a well-known fact that it has problems with light resistance and safety, making it undesirable to incorporate it into cosmetics.

Mica/titanium-based pearl pigments are inexpensive, have no safety issues, and come in a variety of average particle sizes, so they are widely used in cosmetics depending on the desired burl luster. It has a long diameter of 2 to 100 microns and an average thickness of α03 to 1 micron, and has a wide range of particle diameters, and although it is not always satisfactory in terms of gloss, such as good gloss and uniformity, it does not have the drawbacks that pearl pigments have. As a result of intensive research to solve this problem, we found that powder obtained from multi-layered plate-like polymers can be blended into cosmetics, especially transparent cosmetic bases, to create a pearly luster with a unique opalescent feel. The present inventors have discovered that it is possible to obtain highly safe cosmetics having the following properties, and have completed the present invention.

That is, the present invention provides a cosmetic composition characterized in that a transparent cosmetic base is blended with plate-like polymer powder stacked in multiple layers. In particular, the present invention combines a multi-layered plate-like polymer with a transparent cosmetic base, which is not possible with conventional pearl pigments. This is thought to be because conventional pearl pigments produce a pearlescent luster through reflection, whereas diffraction gives a pearlescent feel.

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

The transparent cosmetic base used in the present invention may be any type, such as a transparent oil type, transparent water type, transparent solubilized type, transparent emulsion type, transparent powder type, transparent powder dispersion type, etc., and can have a unique opalescent luster. I can't get it.

(Method for measuring transparency) Cosmetic base is placed on black and white color matching paper for 1'
Apply to a thickness of 75am and measure 55mm using a color analyzer.
Measure the spectral reflectance of 0-. Let the value calculated by the following formula be the transparency.

Transparency (Ta2O) = (1-j) x 100 (phantom V
II However, RB is the spectral reflectance of 5501R' when applied to black paper, and Rw is the spectral reflectance of 5501R' when applied to white paper.
Spectral reflectance at 0 nm.

In addition, water-based, solubilized, and emulsified cosmetic bases are measured after being applied and dried; oil-based waxes and wax-like products are melted and applied and measured after cooling, and powder-based products are measured after being melted and applied. For this, a 10% by weight dispersion was applied to a clear base of nail enamel and measured.

(Left below) -Kiruga: Care must be taken when attempting to obtain a transparent emulsion system, a transparent powder system, or a transparent powder 1 dispersion system. That is, a transparent emulsion system requires some kind of formulation or production method, and when trying to make a transparent powder system or a transparent powder dispersion system, the bending of the base powder is important. By repeating experiments, the inventors were able to obtain a cosmetic with a beautiful opalescent feel.

The multilayered plate-shaped polymer used in the present invention is a multilayered polymer of two or more different types of polymers, and the types of resin include polyhydric alcohols such as glycerin, trimethylolpropane, and pentaerythritol. and anhydrous 7
Polyesters made of acids such as tarric acid, other polyesters, polymethacrylate esters such as polystyrene, polymethyl methacrylate, and polyethyl methacrylate; acrylics such as polyacrylic esters such as polymethyl acrylate and polyethyl acrylate; Resin, polyvinyl chloride
Examples include resins such as polyvinyl acetate, polyvinyl alcohol/polyvinyl acetal, and polyvinylizophenol chloride resin. Among these, those that can be copolymerized also include copolymers.

Among the above polymers, monos or copolymers selected from polyester, polystyrene, acrylic resin, polyolefin, and polyacetate-pynyl are particularly preferred.

The multilayered polymer used in the present invention is a film formed by stacking the various polymers described above in multiple layers, and the number of layers can be arbitrarily selected, but for example, 100.
~300 layers, the thickness of which is 10-50μ.

In the present invention, a powder obtained by cutting the multilayered polymer into pieces into a predetermined size is used. As a method for shredding, for example, a method is used in which the film is placed on a vacuum plate and cut by punching.

Although the particle size of the powder of the present invention can be arbitrarily selected,
For example, a corner with a major axis and a minor axis between 005 mm and 10 mm, a circular shape,
Other powders can always be obtained in a narrow range of particle sizes.

The multi-layered plate-like polymer powder used in the present invention can be obtained from commercial sources, for example, from Mθarl Co., Ltd.
) made Starlight Glitter (5TARL TEi
GL Engineering TTER).

The multi-layered plate-shaped polymer powder may be blended into the transparent cosmetic base by a method in which, for example, conventional pearl pigments are blended as one component of a cosmetic powder. The blending amount can be arbitrarily mixed in the same manner as conventional pearl pigments, but it is generally 0.5 to 50% by weight.

Cosmetics obtained by the present invention include makeup cosmetics such as eye shadow and lipstick, packs, creams,
There are a wide variety of cosmetics, including basic cosmetics such as lotions and soaps, and hair, body, and fragrance cosmetics such as hair lotions, dusting powders, body lotions, and line perfumes. To obtain a new beautiful cosmetic with a transparent opal-like luster that cannot be obtained when a plate-like polymer is blended into a cosmetic, and which is completely impossible by blending a conventional pearl pigment. I can do it. In addition, since the multi-layered plate-like polymer powder according to the present invention has a lower specific gravity than conventional pearl pigments, it is not necessary to thicken the base when blending it into a transparent cosmetic base. In this sense, it can be said that the range of application of the present invention to cosmetics is wide.
