Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a novel cosmetic bar, particularly a cosmetic bar suitable for a pencil shape, and a method for producing the same. For more details,
The present invention relates to a bar-shaped cosmetic that can contain powder at a high concentration and its manufacturing method, and aims to provide a new type of bar-shaped cosmetic that has completely different cosmetic effects, usability, and texture that are not found in conventional bar-shaped cosmetics, and its manufacturing method. It is something.

Conventional bar-shaped cosmetics are molded using an extrusion molding method in which a powder component is added to an oil or wax such as fat, wax, or hydrocarbon as a binder or structuring agent, or by a casting method in a high-temperature fluid state. It is common for so-called oil glue stains to occur. This oil glutamate tinoku is a typical cosmetic formulation that is used in many cosmetics such as lipstick, eye shadow, eyebrow, eyeliner, and blusher, and it comes in various shapes such as a pencil shape and a roll-up container. There is something like that. These have the advantages of being able to be applied directly to the skin, being portable, easy to use, and having a good feel, but on the other hand, they are oily, have poor makeup retention, or have a different feel depending on the temperature when used. It has the following drawbacks. The advantages and disadvantages of these conventional bar-shaped cosmetics are all due to the limited ratio of powder components to oil and wax, but due to manufacturing constraints and quality issues as cosmetics, this ratio has been changed. Since it is not possible to drastically change the properties of bar-shaped cosmetics, it has become an essential property of bar-shaped cosmetics, and there has been a need for improvement. For example, to summarize the properties caused by changes in the ratio of powder to oil or wax in a cosmetic formulation, formulations containing powder below 50% (oily range) give an oily feel; If it is above (powder area), it will give a powdery feel, and if it is between 80 and 50 pieces (middle area), it will give a powdery feel depending on the individual properties of the raw materials used. There is a tendency to give and receive. The bar-shaped cosmetics that have been provided so far are mainly oil-based because the more powder they contain, the more difficult it is to perform operations such as mixing and filling and molding. It is common to set it to ~40%.

Therefore, the obtained product was inevitably accompanied by the drawbacks in the oily region mentioned above. On the other hand, a quality problem is that when the powder component increases, the surface of the rod-shaped tip that comes into direct contact with the skin becomes hard (caking) as it is used, and eventually it becomes impossible to draw. This caking is caused by the fact that the bar-shaped cosmetic is applied directly to the skin, so when the oil content in the bar-shaped cosmetic is low (in the case of bar-shaped cosmetics in the powder area or intermediate area), sebum, sweat, and This is a phenomenon in which other cosmetics adhere to or penetrate the surface of a bar-shaped cosmetic and harden it.

As a result of various experimental studies, the present inventor has developed a new type of bar-shaped cosmetic that eliminates the drawbacks of conventional bar-shaped cosmetics and has completely different cosmetic effects, usability, and texture, etc. This led to the completion of a new manufacturing method to obtain this product.

That is, the present invention relates to a rod-shaped cosmetic product containing gypsum, mica pearl agent, and water-dispersible spherical powder as essential ingredients. Furthermore, a mixed powder containing gypsum, mica-based pearl agent, and water-dispersible spherical powder as essential components is dispersed in water or a mixed solution of water and additives to obtain a fluid clay.
The present invention relates to a method for producing a bar-shaped cosmetic, which is characterized in that the cosmetic is filled into a mold having a columnar filling portion, hardened, and then dried.

To explain in detail the components constituting the rod-shaped cosmetic composition of the present invention, the three essential components of gypsum, mica-based glue, and water-dispersible spherical powder contain 14-60% by weight of gypsum, preferably 18-60% by weight. 52% by weight, mica pearl agent 6-64% by weight,
The amount of water-dispersible spherical powder is 1.8 to 54% by weight, and the powder component to be mixed as desired is 0.5 to 32% by weight of pigment (extender pigment, colored pigment). The main additives are 1 to 50% by weight of oil and 0.5 to 10% by weight of moisturizing agent, respectively, and other additives include appropriate amounts of fragrance, antioxidant, bactericide, and Examples include embalming.

As the gypsum applied to the present invention, either anhydrous gypsum or/and hemihydrate gypsum represented by CaSO4 or/and Ca5O, .1/2 H2O is used, and the crystal forms are α, β, βγ, r etc. does not matter. Examples of mica-based pearling agents include mica, sericite, titanium oxide coatitized mica, pigment color-forming titanium oxide coatitized mica, and the like.

Examples of water-dispersible spherical powders include inorganic powders such as calcium silicate, magnesium silicate, silica, calcium carbonate, and magnesium carbonate, and organic powders such as microcrystalline cellulose, with a particle size of 5 to 30 μm, preferably 10 to 30 μm. It has a true spherical shape or a shape close to a spherical shape with a diameter of 20μ. These mica-based nol agents,
The water-dispersible spherical powder may be used alone or in combination of two or more, depending on the purpose, use, etc. Pigments as powder components, oil agents, humectants and other additives as additives may be those normally used as raw materials for cosmetics, and are appropriately selected from these raw materials. Each component of the above-mentioned rod-shaped cosmetics is selected and used in combination as appropriate depending on the intended use of the product, but in particular, hemihydrate gypsum is used as the gypsum, titanium oxide kochitomica is used as the mica-based pearl agent, and pigment coloring is used. A combination of at least one of the oxidized titanium oxide kochitomica and calcium silicate as a water-dispersible spherical powder in the above blending ratio has particularly excellent moldability, usability, and feel. be.

An important point in the present invention is that if the powder component is simply combined with plaster containing pigments such as talc and kaolin, which are usually used in cosmetics, and other pearlescent agents, it will not be possible to create a bar-shaped cosmetic.
In contrast, phenomena such as significant shrinkage and curvature occur during molding (particularly in the case of pencil-shaped bar-shaped cosmetic integrally molded products) and poor fluidity during filling occur, whereas in the present invention, gypsum and mica-based pearl agents, By using the three necessary components of the water-dispersible spherical powder, these drawbacks have been solved.

Next, to describe in detail the method for manufacturing the bar-shaped cosmetic of the present invention, the powder component consisting of gypsum, mica pearl agent, water-dispersible spherical powder, and pigment is dispersed in water or a mixture of water and additives. Make a fluid slurry. The amount of water or water-additive mixture is 1.3 to 1.8 (preferably 1.5 to 1.8) per 1 part of the powder component.
The weight ratio may be set to 7), and the mixture may be heated and dissolved as necessary.

Fluid slurry has a viscosity (rotational viscometer) of 4.000 when measured within 4 minutes after adjusting the slurry.
cp or less, and is filled into a mold having a columnar filling part. In the case of ordinary bar-shaped cosmetics, this mold has a columnar filling part with a cross-sectional area of 12 to 490 mm, a height of 5.2 u or more, preferably 5.2 to 50 nm, and where the cross-sectional area is A. , V'K x 1.5. In addition, in the case of pencil-shaped bar-shaped cosmetics, the cross-sectional area of the filling part is 3" to 80-(
The cylindrical hole has a diameter of 2 to 10 mm, preferably 5 to 8 mm, and a height of 30 to 120 mm, and is either a bottomed or bottomless through hole. There are various filling methods, but
Examples include pouring filling, nozzle injection filling, press-fitting filling, and the like. The press-filling method uses a device disclosed in a patent application filed on November 17, 1980 (patent application filed by the applicant). A piston portion having an outer diameter that closely matches the inner diameter of the container is press-fitted into the container. This piston part has an arbitrary shape and material, and has one or more columnar through-holes in the direction in which it is press-fitted, so that the contents inside the container can be inserted into the piston at the same time as the piston is press-fitted. The columnar filling part is filled by flowing backwards. Moreover, as a substitute for this piston part, a pipe-shaped content molding holder may be set in the jig and used as the piston part. Compared to the former two methods, such as pour-in filling and nozzle injection filling, this method of press-filling allows the filling of fluid slurry even when the filling opening is a small and narrow pipe-shaped mold such as a pencil-shaped cosmetic bar. It has features that can be advantageously applied even when the viscosity is high, and is excellent in that it can be filled into many filling ports simultaneously in a short time.

In curing the fluid slurry filled as described above, the temperature is 5 to 30 tl', the time is 30 minutes or more, preferably 50 minutes to 4 hours, and drying is done so that the molded product and the mold are dried at the same time. If the mold has a bottom, make sure to point the opening upward so that water, etc. evaporates from the opening of the mold, and if the mold has a through hole, close one opening. , with the other opening facing upward so that water, etc. evaporates only from one opening, and the drying temperature is set to 40-6.
0C1 dry humidity R, l - 180% or less preferably R,
It is desirable to maintain H50 to 75% and adjust the drying time appropriately depending on the cross-sectional area and height of the molded product.

It is also possible to perform vacuum drying depending on the strength of the molded product to significantly shorten the drying time.

In particular, when obtaining a stick-shaped cosmetic product, one or more columnar, for example, bottomless pipe-shaped content molding holders are inserted into the above-mentioned molding jig, and these are inserted into the piston section. By functioning as a container, the contents may be back-filled into the holder when pushed into the lower container containing the contents, and eventually be integrally molded together. Examples of materials that can be used as the holding body include resins (thermoplastic resins such as polyethylene, polyglopylene, and nylon);
, machinable composite materials, wood, metals (aluminum, etc.), alloys (alloys of iron, copper, delumi, etc.), paper, rubber, glass,
Ceramics, ceramics, etc. are listed, and the wall thickness is 1.5 to 2.
．． It is about 5th order. One example of a particularly machinable composite material is a mixture of olefin polymers, waxes, and inorganic powders as disclosed in Japanese Patent Application Laid-Open No. 81810/1983. (These can also be made into a pipe-like shape as described above, and after filling, curing, and drying, they do not release from the droplet mold, and a rod-shaped cosmetic can be obtained by integrating the mold and the molded product.) ) The material of the above-mentioned holder is not necessarily limited to the pencil-shaped shape, and may be applied to a holder of a bar-shaped cosmetic material that forms a desired exterior.

In the production method of the present invention, a curing retarder or curing accelerator, water repellent, or oil repellent may be added to water or the above-mentioned mixed liquid, if necessary. Curing retarders include those that delay the curing time of gypsum, such as phosphates, alkali salts of organic dibasic acids, glue, gelatin, -hydric and polyhydric alcohols, and curing accelerators such as gypsum. Examples of such substances include sodium chloride, potassium chloride, potassium sulfate, potassium alum, and the like. Water repellents and oil repellents include those that have sweat resistance, sebum resistance, and affinity for the skin, such as silane coupling agents, amine-modified 72-carbons, organic polymers with perfluoroalkyl groups introduced, and fatty acids. metal soaps (products produced by substitution reaction of fatty acid soaps and metal salts), etc.

In the present invention, if necessary, the molded product taken out from the mold after drying is immersed in a mixed liquid of a volatile solvent and an oil agent and/or a wax, and the immersion time and the oil agent in the volatile solvent are adjusted. By sufficiently adjusting the wax concentration) and then removing the solvent by drying or the like, it is possible to adjust the oil content in the bar-shaped cosmetic to a high concentration or to apply a wax coating to the surface of the bar-shaped cosmetic.

Next, to explain the effects of the present invention in detail, the bar-shaped cosmetic according to the present invention can have a powder component concentration ranging from an intermediate range to a powder range, so it is possible to change the bar-shaped cosmetic product from an oil gel type, which was previously limited to an oily range. It is not just a product that solves the disadvantages of cosmetics, such as oiliness and poor makeup retention, but
In terms of feel and cosmetic effects, a wide range of products are available, ranging from those that are similar to conventional bar-shaped cosmetics to those that are more similar to cakes. Table 1 below shows the results of a usage test conducted by a panel of 20 beauty specialists. From Table 1, it can be seen that the present invention has a
It is clear that the finish is excellent and the makeup lasts long.

Table-1 A: Conventional oil gel type stick eyeshadow B: Stinoku eyeshadow of Example 1 of the present invention C: Stick eyeshadow of Example 2 of the present invention *Table-1 is for beauty specialty (
Experience) Samples A, B,
This figure shows the mutual comparison evaluation results after using the three products of C for three weeks. (The average value of the evaluation results of the use test was made into a sensory profile.) Furthermore, the bar-shaped cosmetic according to the present invention is characterized by extremely high temperature stability. Conventional bar-shaped cosmetics have extremely strong temperature dependence.
For example, when used at high temperatures (near 40C), it becomes extremely sticky and the bending resistance becomes weaker.
When used in the vicinity of C), there was a drawback that it became hard and difficult to draw. As a result, there are inconveniences in use, such as the flattening being extremely easy to break in the summer and difficult to draw in the winter. This is due to the fact that the main body of the rod has a wax structure and is easily affected by temperature, and there is also an ironic relationship in that the higher the temperature dependence, the better the feel. The rod-shaped cosmetic according to the present invention is formed into a rod by a powder structure component (specifically, the crystal structure of gypsum), and therefore is hardly affected by temperature. The figure shows the results of measuring the bending strength at various temperatures of a conventional bar-shaped cosmetic material and a bar-shaped cosmetic material of the present invention. A is a conventional oil gel type eye shadow, B is a snack eye shadow of Example 1 of the present invention, and C is a snack eye shadow of Example 2 of the present invention. As a method, the strength was measured based on the load value (unit: g) when a snack eyeshadow with an outer diameter of 6φ and a length of 35 mm was folded at the center between 20 spans. From this, it can be seen that the conventional cosmetics have a large temperature dependence, while the bar-shaped cosmetics of the present invention are not easily affected by temperature.

As mentioned above, gypsum crystals are used as the structuring agent in the rod-shaped cosmetic of the present invention, but the structuring agent may be inorganic powder or organic powder (for example, PVA, which solidifies after the solvent evaporates). .

Conventional bar-shaped cosmetics (including soluble organic polymer substances such as PE, CMC, etc.)
2-12934, JP-A No. 54-80428, JP-A No. 54-163831, etc.) have an extremely weak resistance against drop impact force. On the other hand, the pencil-shaped bar-shaped cosmetic material particularly shown in Example 4 of the present invention has sufficiently increased impact strength.

In addition, when applied directly to the skin, the bar-shaped cosmetics in the intermediate to powder range that have been known up until now have the effect of reducing the amount of sebum and desk cosmetics.
The cake surface of the bar-shaped cosmetic becomes caked due to sweat, etc.

On the other hand, in the case of the present invention, by making the cosmetic into a pencil-shaped bar, the degree of compaction of the powder components that make up the bar-shaped structure can be sufficiently reduced, and at the same time, the bending strength is maintained and the caking phenomenon is prevented. It is possible to do so.

Cosmetics using baked stone powder include, for example,
No. 36595, but this patent relates to a method for producing a cake makeup composition in which known cosmetic raw materials such as calcined gypsum, water, and additives such as extender pigments are kneaded together and poured into a dish to solidify. A plate-shaped receiver with a large filling opening, which is unique to cake make camp ingredients, is used to fill a dish, and when used, the contents are applied with a puff or brush.

In contrast, the main purpose of the present invention is to provide a pencil-shaped cosmetic bar that does not require an applicator, and is made by filling the contents into a vibrator-shaped mold with an extremely narrow filling opening and molding it in one piece. Since the patent relates to a method for producing a bar-shaped cosmetic material that can also be manufactured by the patent, the above-mentioned patent is apparently unrelated to the establishment of the present invention.

Next, examples of the present invention will be shown. The proportions of each component are parts by weight. (The numbers in parentheses after the parts by weight are the percentages by weight of the product excluding water.) Example 1 Snack Eye Shadow B (Gypsum 11.0 (34,700
