Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair coloring cosmetic composition, and more particularly to an improvement in a hair coloring cosmetic composition containing titanium mica as a pigment and being particularly suitable for being discharged from an aerosol container in the form of a foam. About.

[0002]

2. Description of the Related Art Heretofore, as this type of hair coloring cosmetic composition, there has been marketed one which squirts from an aerosol container in a colored foaming state to temporarily color the hair. Of course, any surface to be coated is colored, resulting in inconvenience such as soiling of clothes and hands during hair makeup work. Moreover, even after coating, the surface to be coated is dark,
Since it was colored and colored regardless of its colorlessness, there was an unpleasant sensation that the coloring pigment drips from the hair to the face due to rain, sweat, and the like, and stains the face and clothes and pillow covers.

[0003] On the other hand, a hair coloring cosmetic composition containing titanium mica as a coloring agent is disclosed in JP-A-62-255.
No. 414. This hair coloring cosmetic composition is characterized by containing a pigment, that is, mica titanium as a color former, a carboxyvinyl polymer as a thickener, and an anionic resin as a binder, and exhibits excellent foaming properties at the time of injection. When applied to the head hair, it is excellent in color development and adhesiveness, dries in a short time, and improves combability. However, the above problem has not been solved at all.

In selecting mica titanium as a pigment, the present inventor has developed a special mica having a type of interference that does not form a color on a colorless or light-colored coated surface but forms a clear color on a dark-colored coated surface. By using titanium, by developing a hair coloring cosmetic composition that develops a clear color on a dark-colored coated surface and hardly develops a colorless or light-colored coated surface,
Although the above problems have been solved, the following problems have been encountered when such special mica titanium is used. That is, in the case of the conventional product, while using a technique of wrapping and coloring the hair using a large amount of pigment, when using the special mica titanium having the above-described interference action as the pigment, Then, a technique of forming a trace amount of mica titanium layer on dark-colored hair and causing it to reflect and develop color (interference) to obtain a colored state is used. As a result, the amount of titanium mica having this interference effect in the hair coloring cosmetic composition is relatively small, and when used, this small amount of titanium mica is uniformly mixed in the hair coloring cosmetic composition. It is particularly required to erupt in a squirt state. To this end, sedimentation of titanium mica having this interference action is prevented, preventing mica titanium from accumulating unnecessarily only near the bottom in the aerosol container, and simultaneously shaking the aerosol container prior to use. At this time, it is necessary to easily disperse the mica titanium so that a uniform distribution state can be obtained in the entire container. However, when such prevention of sedimentation and redispersibility are demanded, the color development by the above-mentioned mica titanium becomes worse, bubbles easily form on the painted surface (small bubbles remain on the painted surface), and A bad effect such as a decrease in adhesiveness occurs.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention provides good sedimentation prevention and redispersibility of a pigment, and prevents a decrease in color development and the occurrence of foaming on a coated surface.
Also, a hair coloring cosmetic composition which can prevent titanium mica from falling off from the hair in a short time, and develops a vivid color on a dark-colored coated surface and hardly develops a colorless or light-colored coated surface. Is to be provided.

[0006]

The first invention of the present application provides (A) a crosslinked polymer as a mixed pigment dispersion stabilizer,
(B) Magnesium silicate containing 35% or more of silicon dioxide or magnesium aluminum silicate containing 35% or more of silicon dioxide or a mixture thereof is blended, and as a pigment, color is formed on a colorless or pale color coated surface. A hair coloring cosmetic composition, characterized in that mica titanium having interference of a type that produces a clear color on a dark-colored coated surface is compounded, and a polymer compound is compounded as a hair-forming film-forming agent. provide. This hair coloring cosmetic composition comprises:
It can be carried out as being discharged from the aerosol container in the form of a foam, but even if it is not necessarily carried out in the form of being discharged in the form of a foam, a change in the above-described coloring and non-coloring in relation to the color of the surface to be coated Is seen.

However, the foamed state is easier to use, and the bubbles can enhance the colorless or white feeling at the time of ejection. According to the second invention of the present application, a surfactant is added as a foaming agent in addition to the above-described blend to form a content composition, and the content composition and the propellant are sealed in an aerosol container. And a hair coloring cosmetic composition characterized in that when it is ejected from an aerosol container, it is ejected from a colorless or nearly colorless slightly colored to white color, and develops a clear color on a dark-colored coated surface. Things.

In each of the above-mentioned inventions of the present application, specifically, “light color” is a color having a lightness of 7 or more, “dark color” is a color having a lightness of 5 or less, and “lightly colored” is a lightness. It can be eight or more colors. However, the light color and the dark color are relative concepts, and `` mica titanium having a type of interference that does not form a color on a colorless or light-colored coated surface but forms a clear color on a dark-colored coated surface '' The term "mica titanium" means that the color development state becomes favorable on a relatively dark color to-be-coated surface due to the difference between the light and dark colors of the surface to be coated. Therefore, "when squirting from an aerosol container, squirting in white from a colorless or near-colorless slightly colored, and vividly develops on a dark coated surface" means, relatively according to the coloring conditions of mica titanium. It means that the color development state becomes good on the dark coated surface. In the practice of the present invention, components commonly used as cosmetics sealed in an aerosol container such as purified water or lower alcohol, and other ingredients such as fragrances, humectants, oils, hair nutrition, pH adjusters, etc. It goes without saying that the components can be added and blended. As the lower alcohol, an alcohol having 2 to 4 carbon atoms can be used, but the use of ethanol is most preferable from the viewpoint of drying properties and aromaticity.

The crosslinked polymer used in the present invention includes acrylic acid, methyl acrylate, ethyl acrylate, propyl acrylate, n-butyl acrylate, tert-butyl acrylate, sec-butyl acrylate,
N-hexyl acrylate, cyclohexyl acrylate,
Acrylic esters such as n-octyl acrylate, 2-ethylhexyl acrylate, n-lauryl acrylate, 2-ethylhexyl methacrylate, n-methacrylic acid
Methacrylic esters such as lauryl, vinyl ethers and vinyl esters such as methyl vinyl ether and ethyl vinyl ether, and divinyl benzene, ethylene glycol diacrylate, ethylene glycol dimethacrylate, and trimethylol propane acrylate having a plurality of ethylenically unsaturated bonds. A water-soluble or water-insoluble cross-linked polymer produced by subjecting such a monomer to suspension polymerization, dispersion polymerization, or emulsion polymerization can be used.

The magnesium silicate containing 35% or more of silicon dioxide used in the present invention includes bentonite,
Examples of magnesium aluminum silicate containing silicon dioxide of 35% or more, such as Laponite (Nippon Silica Industry Co., Ltd.) and hectorite, are Vegum (RT Vand).
ervilt (US), smecton (Kunimine Industries) and the like. These can be used alone or in combination.

Here, (A) a crosslinked polymer and (B)
Magnesium silicate containing 35% or more of silicon dioxide or magnesium aluminum silicate containing 35% or more of silicon dioxide or a mixture thereof has an effect of preventing precipitation and improving redispersibility alone.
Even when these are used alone to obtain the desired effect of preventing precipitation and redispersibility, there are the following problems. That is, if the effect of preventing precipitation or redispersibility is to be obtained only by the crosslinked polymer, the viscosity of the content composition increases, and bubbles easily form on the coated surface. On the other hand, if an attempt is made to obtain a precipitation-preventing effect or re-dispersibility with only magnesium silicate or magnesium aluminum silicate containing silicon dioxide in an amount of 35% or more, a problem that mica-specific coloration is dulled will be encountered. The inventor of the present application has found that the combined use of (A) and (B) makes it possible to obtain the desired effect of preventing precipitation and redispersibility in a drastically smaller amount than when these are used alone. Thus, the present application has been completed.

The (A) crosslinked polymer is contained in the content composition (not containing a propellant) in the range of 0.01 to 0.5% by weight, and (B) magnesium silicate containing silicon dioxide in an amount of 35% or more. Alternatively, magnesium aluminum silicate containing 35% or more of silicon dioxide or a mixture thereof is preferably used in a range of 0.05 to 1.49% by weight, and a mixed pigment dispersion of (A) and (B) is used. The total content of the stabilizer in the composition (without propellant) is
0.15 to 1.5% by weight is suitable, and particularly preferably 0.3 to 1.0% by weight.

The titanium mica used in the present invention is obtained by coating a thin layer of titanium oxide on the powder of mica, and is an application of the fact that the coloration of titanium mica varies depending on the thickness of the thin film of titanium oxide. In particular, a type that does not form a color on a colorless or light-colored coated surface, but forms a clear color on a colored (dark) coated surface, such as Timiron Super Green and Timi
ron Super Blue, Timiron Super Red, Timiron Super
Gold, Timiron Gold MP-127, Timiron Blue MP-155,
Timiron Green MP-165, Timiron Red MP-175, Timiron

It is preferable to use S, STARLIGHT COLORS, SILK COLORS (all manufactured by Merck Japan KK) and the like. However, when the content composition and the propellant squirt from the aerosol container, they squirt from a colorless or nearly colorless fine color to white, and do not develop on the colorless or pale color coated surface, but on the dark colored coated surface. It is also possible to mix and use other pigments such as titanium oxide coated on the mica powder, as long as the colorant is coated on the upper surface, as long as the color can be sharply formed. Examples thereof include those coated with iron sesquioxide, navy blue, carmine, black iron oxide (trade name: Colorona R)
ed Gold, DichronaBR (all manufactured by Merck Japan KK) and the like. However, if a large amount of a titanium oxide coated on mica powder and further coated with a colorant on its upper surface is blended, it is difficult to satisfy the above-described coloring conditions, and most preferably, these colorants are used. Only the interference-free mica powder not coated with the colorant is compounded, without coating.

In the present invention, the polymer compound as a hair-forming film-forming agent is used as a binder for titanium mica, and such a polymer compound is contained in the obtained content composition (propellant is not used). It is preferable that the polymer compound is contained in an amount of 0.1 to 15% (as a resin solid content) in the polymer compound (not included). If it is less than 0.1%, the adhesion of the mica titanium to the surface to be coated is poor, and the titanium mica may fall off the coated surface after the coating treatment. Also, 15
%, The coating film (film) becomes thicker, bubbles appear (a state in which some fine bubbles remain), etc., and the color development worsens.
The hair to be coated may be uncomfortablely hard.

As the polymer compound used in the present invention as a hair styling film forming agent, nonionic polymers, anionic polymers, cationic polymers and amphoteric polymers can be used. The nonionic polymer, anionic polymer and amphoteric polymer can be used alone or as a mixture of two or more. Cationic polymers have excellent properties to penetrate between the hairs and have good properties such as good fixation to the hair, giving flexibility, and a moist and supple hair styling effect, but they cannot impart sufficient gloss to the hair. In addition, since the film is sometimes too flexible, a setting effect of an appropriate strength cannot be obtained, and furthermore, there is a disadvantage that the film becomes sticky and it becomes difficult to rinse at the time of shampooing. It can be used satisfactorily by mixing it with an ionic polymer or amphoteric polymer.

Examples of the nonionic polymer include polyvinylpyrrolidone, polyvinylpyrrolidone / vinyl acetate copolymer, cellulose derivatives having a molecular weight of 10,000 to 10,000,000, and methoxyethylene maleic anhydride copolymer.

Examples of the anionic polymer include acrylate / methacrylate copolymer, vinyl methyl ether / butyl maleate copolymer and the like.

Examples of the cationic polymer include a cationized product of a vinylpyrrolidone / dimethylaminoethyl methacrylate copolymer and a quaternized derivative of cellulose ether (eg, cellulose ethers such as hydroxyethylcellulose, methylcellulose, ethylcellulose, hydroxypropylcellulose, and hydroxypropylmethylcellulose; Examples thereof include those quaternized using a cationizing agent such as greasel trimethylammonium chloride).

Examples of the amphoteric polymer include hydroxypropyl acrylate / butylaminoethyl methacrylate / octylamide acrylate copolymer.

In implementing the present invention, what system (what nature)
It is theoretically possible to select whether it is appropriate to use the polymer of the above, depending on the feeling after use, the demand and the relationship with other compounds,
It may be determined by trial and error.

Next, as surfactants as foaming agents, various surfactants conventionally used as foaming agents in the field of cosmetics (for example, various surfactants listed on the basis of cosmetic raw materials) can be used. Any of nonionic surfactants, anionic surfactants, amphoteric surfactants, and cationic surfactants can be used. Examples of nonionic surfactants include glyceryl monostearate, ethylene glycol monostearate, propylene glycol monostearate, propylene glycol distearate, diethylene glycol monostearate, and monoethanolamide of coconut oil fatty acid. Yes, and as the anionic surfactant,
Examples thereof include zinc laurate, magnesium stearate, sodium lauryl sulfate, sodium polyoxyethylene lauryl ether sulfate, and sodium polyoxyethylene lauryl ether phosphate. Examples of amphoteric surfactants include sodium β-laurylbuminopropionate, betaine lauryldimethylaminoacetate, potassium coconut oil fatty acid collagen peptide, betaine stearyldimethylamino acid, betaine, and glycyrrhetinyl stearate. Examples of the cationic surfactant include stearyltrimethylammonium chloride, distearyldimethylammonium chloride, benzethonium chloride, alkylisoquinolinium bromide, lauryltrimethylammonium chloride, and alkyltrimethylammonium chloride. This surfactant may be used by selecting the most suitable surfactant according to the cross-linked polymer or film-forming polymer and other components to be mixed together or in consideration of a desired foaming state. If it is not discharged, it is useless.

As the propellant, conventionally used LPG, dimethyl ether, carbon dioxide gas, nitrous oxide gas, nitrogen, and HFC such as 134a can be used. The blending amount of the propellant can be appropriately changed depending on the type of gas used on condition that the propellant is obtained, but generally, it is appropriate to be within 20% by volume.
