Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slurry-filled solid powder cosmetic containing a specific pearlescent pigment, and more particularly, to a solvent having an unprecedented pearly luster and being required for filling the slurry. The present invention relates to a slurry-filled solid powder cosmetic capable of reducing the amount.

[0002]

2. Description of the Related Art Conventionally, when a solid powder cosmetic such as eye color and teak is prepared using a pearlescent pigment, the pigment is mixed with an extender, a pearl agent and a coloring pigment, and then mixed with an oil component. And the resulting powder has been molded by a compression press.

[0003] However, in these methods, when mixed with powder or oil, the pearlescent pigment is destroyed by receiving a high shearing force, so that there is a problem that the luster of the pearlescent pigment is remarkably reduced. In addition, since pearlescent pigments are plate-like and have a relatively large particle size, there is also a problem that if they are incorporated in a large amount into cosmetics, the press moldability will be significantly reduced.

[0004] In order to solve these problems, a method has been used in which a cosmetic base material and a pearlescent pigment are mixed with a solvent to form a slurry, which is filled in a container or the like, and then the solvent is removed to form the slurry. Have been. However, in general, plate-like powders having a large particle size, such as pearlescent pigments, have extremely poor fluidity when slurried with a solvent together with a cosmetic base. Solvents have been required.

[0005] On the other hand, when a slurry containing a large amount of solvent is dried as it is, the drying time becomes extremely long, and in addition, there have been problems such as cracks on the surface of the molded product and shrinkage of the bulk. Therefore, a method of recovering the solvent with an absorber when filling the slurry is generally used, but even in this method, it is extremely difficult to recover the solvent at the time of filling when the amount of the solvent when slurrying is large. In addition, there is a problem that the oil and the solvent disappear together when the solvent is recovered.

[0006]

Therefore, it is desired to provide a solid powder cosmetic which retains excellent pearl luster and does not require a large amount of solvent in the production, even though it is a solid powder cosmetic. I was

[0007]

Means for Solving the Problems In view of the above situation, the present inventors have conducted intensive studies and as a result, selected a glass flake whose surface was coated with a metal oxide as a pearlescent pigment, and used this as a cosmetic base. After mixing, the mixture is mixed with a solvent to form a slurry, and further filled in a container or the like, and a solid powder cosmetic having an excellent pearlescent appearance can be obtained by removing the solvent, and in producing the cosmetic, a large amount of It was found that the solvent was unnecessary, and the present invention was completed.

That is, the present invention provides a slurry-filled solid powder cosmetic which is formed by dissolving a cosmetic base in a solvent to form a slurry, filling the slurry into a container or the like, and removing the solvent to form a slurry. A pearl luster pigment having an average thickness of 0.1 to 3.0 μm, an average particle diameter of 1 to 700 μm, and an aspect ratio of 5 to 500, in which the surface of the glass flake was coated with a metal oxide, was mixed into the agent. It is intended to provide a slurry-filled solid powder cosmetic characterized by the following.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In the present specification, a slurry-filled solid powder cosmetic is a solid powder obtained by once dissolving a powder cosmetic in a solvent, filling a slurry into a container or the like, and then molding. It means cosmetics. The molding method is not particularly limited, but is generally carried out by simultaneously filling the slurry with the powder cosmetic in a container or the like or after filling the slurry, and then removing the solvent by a known method and molding. In consideration of the residual amount of the solvent in the molded article, ease of recovery, and the like, it is preferable to employ a method in which pressure is applied at the time of filling the slurry to remove the solvent through the absorber or the discharge hole.

The pearlescent pigment used in the non-compressed solid cosmetic of the present invention is obtained by using glass flake as a base material and coating the surface with a metal oxide. Here, the glass flake refers to a silica (SiO ₂ ) of 45 to 75% by mass.
It is obtained by pulverizing a glass film containing about (hereinafter simply referred to as “%”). Examples of the glass flakes include those produced by a melting method, and more specifically, those produced by the method described in JP-B-41-17148 and JP-B-45-3541. Examples can be given.

[0011] The glass flakes obtained by the above method are:
Since the molten glass having a free surface is cooled and solidified, its surface is very smooth, and since it is amorphous and has no cleavage, there is almost no step on its surface. Also,
Since it has some flexibility compared to silica glass containing 80% or more of silica, it is hard to be crushed and is suitable for blending into cosmetics.

In terms of shape, the average thickness is 0.1 to 3.0.
μm glass film is crushed and classified, and the average particle size is
00 μm, average thickness 0.1-3.0 μm, aspect ratio 5
~ 500 glass flakes can be obtained.

The glass used as the raw material for the glass flakes may be any composition that contains silica in the above-mentioned range and can be melt-molded.
S glass, E glass, C glass and the like are exemplified, but C glass is particularly preferable since a step is hardly generated on the surface and smoothness is easily obtained.

The pearlescent pigment used in the present invention is obtained by coating the surface of a glass flake with a metal oxide.
Average thickness is 0.1 to 3.0 μm, average particle size is 1 to 700 μm
m and an aspect ratio of 5 to 500. Regarding the average thickness, glass flakes have a production technology of 0.1.
It is difficult to make it thinner than μm, and on the other hand, if it is thicker than 3.0 μm, it gives a rough feeling and is not preferable in touch.

On the other hand, if the average particle size is less than 1 μm, sufficient glitter cannot be obtained, while if the average particle size is greater than 700 μm, the graininess becomes too strong and the gloss becomes too strong to be unnatural. Is also not preferred.

Further, when the aspect ratio is less than 5, the feeling of spreading on the skin is poor, and when it is more than 500, the feeling of fitting to the skin is poor, and the appearance of the metal coating is also poor. The gloss is too strong, which is not preferred for the present invention. Here, the “aspect ratio” indicates a value obtained by dividing the average particle size of the glass flakes by the average thickness.

By coating the glass flakes with a metal oxide, a pearlescent pigment exhibiting a luster similar to that of a pearl in appearance can be obtained. As the metal oxide used for this coating, titania (TiO _{2) is used.} ), Zirconia (Z
rO ₂ ) and metal oxides such as iron oxide. The method of forming the coating with the metal oxide may be a known technique, for example, a method described in JP-B-43-25644, JP-A-47-34529, or the like. Specifically, glass flakes are suspended in a titanyl sulfate solution or a titanium tetrachloride solution, and titania is precipitated by raising the temperature of the solution to form a thin film on the glass flakes. However,
The present invention is not limited to this method, and there is no particular limitation as long as it can provide a thin film on the glass flake.

In the pearlescent pigment, by controlling the thickness of the film on the glass flake, an arbitrary color tone due to interference can be developed. The thickness of this coating is preferably 20 to 250 nm. When the thickness is less than 20 nm, it is difficult to exhibit glitter, while when the thickness is more than 250 nm, a glittering appearance having an appropriate transparency may not be obtained. Since the film has such a small thickness, the thickness of the glass flakes and that of the pearlescent pigment are not much different.

Further, the pearlescent pigment is preferably a fluorine compound, a silicone oil agent, a metal soap, a lecithin, a hydrogenated lecithin, an N-long-chain acylamino acid, for imparting oil repellency or water repellency and improving dispersibility. collagen,
It may be treated with one or more known coating agents such as hydrocarbons, higher fatty acids, higher alcohols, esters, waxes, waxes and surfactants.

The slurry-filled solid powder cosmetic of the present invention comprises:
It is prepared by dissolving the cosmetic base containing the pearlescent pigment in a solvent to form a slurry, filling this into a container, and removing the solvent. The amount of the pearlescent pigment in the cosmetic of the present invention is not particularly limited, but is preferably 0.5 to 80% by mass in the cosmetic base in terms of pearlescent and moldability, and 1 to 50%. % Is more preferred.

On the other hand, the solvent used for dissolving the cosmetic base preferably has a boiling point of 200 ° C. or lower. Specific solvents include water or low-boiling alcohols such as ethyl alcohol, isopropyl alcohol, and n-butanol, low-boiling hydrocarbons, low-boiling linear or cyclic silicones, and low-boiling fluorine compounds. Alternatively, they are used as a mixture of two or more. The amount used is not particularly limited, but is preferably in the range of 10 to 150% based on the cosmetic base. If the amount used is small, the powder may not be sufficiently wetted by the solvent, may be uneven, and the moldability may be deteriorated. Conversely, if the amount used is too large, it will be difficult to sufficiently recover the solvent component, the drying property will be significantly reduced, and the loss of the oil agent will increase, which is not preferable in terms of moldability.

In preparing the slurry-filled solid powder cosmetic of the present invention, a binder may be added for the purpose of maintaining the shape of the cosmetic after molding and imparting strength. Any binding molding agent that can be blended can be used as long as it is used in a conventional slurry filling method. Specific examples include clay minerals such as smectite, benton, and silicic anhydride, gypsum, and water-soluble polymers. One or more of these binding molding agents can be used as long as the effects of the cosmetic of the present invention are not impaired.
