Description

[Detailed description of the invention]

[Industrial Application Field] The present invention provides a solid material that spreads smoothly, has an excellent moisturizing effect on the skin and lips, has very little moisture scattering during storage, and has excellent color stability over time. Concerning makeup cosmetics. The solid makeup cosmetics to which the present invention is applied include 4-20% wax, 35-80% oil, and if necessary, 0-60% pigment, and 0-60% surfactant.
2% by weight as a main component, is heated and melted, poured into a stick mold or medium plate, and cooled to solidify.Stick or medium plate type cosmetics (hereinafter referred to as oil-based solid cosmetics for convenience) ), or the main constituents are 40-90% by weight of pigment, 4-35% by weight of oil, and if necessary 0-5% by weight of wax, and 0-2% by weight of surfactant, and after stirring and mixing, press into a medium dish. This is a pressed-type cosmetic (hereinafter referred to as a pressed-type powder cosmetic for convenience) obtained by molding. [Prior art] Water is blended into a solid cosmetic to apply it to the skin and lips. Attempts to obtain a moisturizing effect and a cooling sensation have been made for a long time. For example, Patent No. 1125122 provides an emulsified lipstick. Also, in addition to that, JP-A-53
Applications such as JP-A-127841, JP-A-54-49337, and JP-A-56-45045 have been filed, but in all of them, water is added together with a surfactant and polyhydric alcohol, and water-in-oil type (W/O type) is applied. We are making emulsified lipstick. These lipsticks, oil-based solid cosmetics, are formulated with water, so they feel good on the skin, have high moisturizing properties, and are prone to sweating and powdering (oil and wax in the ingredients precipitate on the surface of the cosmetic over time). ) etc. have good stability over time, and are also highly safe, but on the other hand, the water contained in them gradually evaporates during storage over time, causing fading and falling out of the container, or the surface loses its luster significantly.
Color changes often occurred due to pigment migration from the oil phase to the water phase or from the water phase to the oil phase. For this reason, whenever water was added, it had to be kept to a very small amount. Also, when water is added to pressed powder cosmetics, water scatters over time, creating a gap between the contents and the inner plate, causing the contents to jump out of the inner plate or causing the surface to become hard. It will happen. Also, JP-A-54-126739 and JP-A No. 54-126740
In this issue, we use clay minerals swollen with liquid crystals consisting of a surfactant-water system to swell organic solvents.
Although gelled cosmetics have been described, these still suffer from the above-mentioned drawbacks due to the high ratio of surfactant to water. Furthermore, since organic solvents exist together with water between the layers of clay minerals, pigments and the like in cosmetics migrate between the aqueous phase and the oil phase, resulting in a problem of color tone change. [Problems to be Solved by the Invention] As a result of intensive studies to solve the above-mentioned drawbacks when water is added to solid cosmetics, the present inventors found that water-swellable clay minerals (hereinafter referred to as We have discovered that by incorporating clay minerals (simply referred to as clay minerals) and fixing and protecting water between the layers of the clay minerals, we can improve water retention and stably incorporate water into solid cosmetics, and have accomplished the present invention. It came to this. In other words, it was possible to provide a solid makeup cosmetic that inherits the advantages of emulsified solid cosmetics and has excellent stability over time (content fading, gloss, color stability, etc.). [Means for solving the problem] That is, the present invention provides 10
This is a solid makeup cosmetic containing clay minerals swollen with ~100% by weight of water and 0~35% by weight of a surfactant relative to the water. The configuration of the present invention will be explained in detail below. The blending ratios of oil, pigment, wax, and surfactant used in the present invention are shown in Table (1).

The present invention will be explained in more detail with reference to Examples below. It goes without saying that the scope of the present invention is not limited to these Examples, and the blending amounts are expressed in % by weight. Example 1 Lipstick No. 1 Polyethylene wax 7 2 Ceresin wax 4 3 Candelilla wax 7 4 Carnauba wax 1 5 Castor oil 20 6 Liquid paraffin 25.5 7 Glycerol tristearate 20 8 Titanium corded mica 5 9 Yellow iron oxide 1 10 Red iron oxide 0.3 11 Red No. 204 0.2 12 Dibutylhydroxytriene Appropriate amount 13 Fragrance Appropriate amount 14 Glycerol monooleate 1 15 Pure water 3 16 Synthetic hectorite (Laponite XLG manufactured by Laporte) 5 (Production method) No. 5 and No. 6 Take a part of, disperse No. 16, and further
Add No. 14 and disperse. No. 15 was gradually added to this dispersion and stirred vigorously for 10 minutes at 10,000 rpm using a homomixer to obtain a paste composition. On the other hand, Nos. 1 to 7 were placed in a pot and heated and melted at 90°C. Nos. 8 to 11 were added and dispersed at 85°C. Further, No. 12, No. 13 and the paste composition prepared in advance are dispersed and mixed at 80°C. After degassing,
Fill the specified container. The resulting lipstick was stored at -5℃, 25℃, and 45℃ for one month.
Furthermore, although the samples were left under aging conditions (-5°C to 45°C), no deterioration (loss of content, loss of gloss, or change in color tone) was observed at all levels. In addition, we conducted a one-month usage test with a panel of 50 people.
A moisturizing effect was clearly observed. Comparative example 1 Lipstick No. 1 Polyethylene wax 7 2 Ceresin wax 4 3 Candelilla wax 7 4 Carnauba wax 1 5 Castor oil 20 6 Liquid paraffin 25.5 7 Glycerol tristearate 20 8 Titanium corded mica 5 9 Yellow iron oxide 1 10 Red iron oxide 0.3 11 Red No. 204 0.2 12 Dibutylhydroxytriene Appropriate amount 13 Flavoring Appropriate amount 14 Sorbitan sesquioleate 2 15 Pure water 3 16 Propylene glycol 2 17 Sorbit 2 (Production method) Heat No. 1 to No. 7 in pot to 90℃ Heat and dissolve, then No.
Add and disperse No. 8 to No. 13. Further, gradually add No. 14 and No. 17 to the pot, and stir at 6000 rpm for 10 minutes using a homomixer. Next, No. 15 and No. 16 were gradually added at 80°C, and stirred at 10,000 rpm for 10 minutes. After degassing, fill it into a designated container. When the obtained lipstick was left for one month at the same level as in Example 1, the higher the temperature, the more noticeable the content faded, the gloss decreased, and the color tone changed. In addition, the results of a one-month usage test conducted by a panel of 50 people showed that it had a clear moisturizing effect. Comparative example 2 Lipstick No. 1 Polyethylene wax 7 2 Ceresin wax 4 3 Candelilla wax 7 4 Carnauba wax 1 5 Castor oil 25 6 Liquid paraffin 29.5 7 Glycerol tristearate 20 8 Titanium corded mica 5 9 Yellow iron oxide 1 10 Red iron oxide 0.3 11 Red No. 204 0.2 12 Dibutylhydroxytriene Appropriate amount 13 Fragrance Appropriate amount (manufacturing method) Same as the manufacturing method of the oil phase in Example 1. No deterioration was observed when the resulting lipstick was left at the same level as in Example 1 for one month, but in a one-month use test conducted by a panel of 50 people, no moisturizing effect was observed.

is gradually added, and after dispersion, the mixture is processed several times using three-stage rolls to adjust the water-containing base. On the other hand, No. 1 to No. 7 were placed in a pot, and after heating and melting at 90°C, No. 9 to No. 13 were added and dispersed and mixed at 85°C. Next, add No. 17 to No. 19 and the pre-adjusted water-containing base to 85
Disperse and mix at ℃. After degassing, it is filled into a predetermined container and cooled to solidify. The resulting lipstick was stable over a period of one month, and also showed good moisturizing effects in use tests. Furthermore, the blended amino acids were stably blended into the aqueous phase even after one month. Example 3 Solid foundation No. 1 Mica 40 2 Talc 15 3 Titanium dioxide 20 4 Iron oxide 3.5 5 Liquid paraffin 5.5 6 Pure water 6 7 Montmorillonite (Vanderbuilt Veegum S-6198) 10 8 Fragrance Appropriate amount 9 Propyl Paraben Appropriate amount (manufacturing method) Pour No. 7 into a Henschel mixer, gradually add No. 6, mix, and adjust the water-containing base in advance. On the other hand, after mixing No. 1 to No. 5 and No. 9 with another Henschel mixer, No. 8 and the water-containing base are added and further mixed with a Henschel mixer. Then, it was finely pulverized and compression molded into a predetermined medium plate to obtain a solid foundation. The obtained foundation was also stable over a period of one month, with no gaps between the contents and the inner plate, and even in a test conducted by a panel of 50 people, it remained cool when applied. It was confirmed that the skin felt moisturized and remained moisturized after application. Comparative Examples 3 and 4 Foundation

[Table] (Manufacturing method) Comparative example 3: Mix Nos. 1 to 6 uniformly in a Henschel mixer, then add Nos. 8 and 9, and pulverize. The pulverized product is press-molded into a predetermined medium plate. Comparative Example 4: Same as Comparative Example 3. However, instead of No.6
Blend No.7. Comparative Example 3 is a conventional type of solid foundation, but since it does not contain water, no moisturizing effect is felt at all. Comparative Example 4 is an example in which water is mixed without using clay minerals, but the water scatters over time, creating a gap between the inner plate and the contents, making the puff hard to use, and the puffs are all very bad. The color tone also became darker, indicating that iron oxide had migrated from the oil phase to the water phase. Example 4 Blush No. 1 Talc 58.3 2 Mica 20 3 Titanium dioxide 10 4 Titanium coated mica 6 5 Lanolin 3 6 POE (10 mol) stearyl ether 0.2 7 Synthetic hectorite (Laponite CP manufactured by Laporte) 1 8 Pure water 1 9 Glycerin 0.5 (Production method) Mix Nos. 1 to 4 well with a blender.
On the other hand, No. 5, No. 6, No. 9 and No. 7 were placed in a kneader and kneaded thoroughly for 1 hour to obtain a paste composition. The paste composition is gradually added into a blender and mixed uniformly. After filtering out impurities, the mixed product is press-molded into a predetermined medium plate. The resulting blusher adheres well to the skin and feels incredibly fresh for a solid type blusher. In addition, the product was stable over time for one month, with no signs of fading, surface hardening, color change, etc. Example 5 State Eye Shadow No. 1 Polyethylene wax 4 2 Carnauba wax 1 3 Kaolin 15 4 Mica 10 5 Titanium dioxide 10 6 Yellow iron oxide 3 7 Black iron oxide 1 8 Ultramarine 8 9 Dimethylpolysiloxane (manufactured by Shin-Etsu Chemical KK) Silicone KF96-5CS) 10 10 Liquid paraffin 29 11 Sorbitan monooleate 1 12 Montmorillonite (Vanderbuilt Vegum HV) 7 13 Pure water 5 14 Fragrance Appropriate amount (manufacturing method) Part of No. 10, No. 11 and No. 12 into the container No.13
While gradually adding, mix and disperse. Furthermore, it was wet-pulverized in a pearl mill (using zirconia beads with a diameter of 1.5 mm) to obtain a water-containing base. On the other hand, the remainder of No. 10 and Nos. 1 to 9 were placed in a pot and dispersed at 90°C.
Furthermore, the pre-adjusted water-containing base is added and mixed and dispersed using a homomixer at 85°C and 5000 rpm for 10 minutes. After degassing, it was filled into a predetermined feeding container and cooled to obtain the target static eye shadow. The obtained state eye shadow spread smoothly and had a moist feel. Moreover, even after one month of aging, no change in content, color tone, or usability was observed. Example 6 Foundation No. 1 Mica 55 2 Titanium dioxide 15 3 Kaolin 15 4 Yellow iron oxide 1 5 Red iron oxide 1 6 Black iron oxide 0.1 7 Liquid paraffin 5 8 Lanolin 3 9 Montmorillonite (Vanderbult Veegum D) 3 10 Purified water 1.5 11 Sodium L glutamate 0.15 12 Hyaluronic acid 0.05 13 Water-soluble vitamin E 0.2 14 Fragrance Appropriate amount (manufacturing method) Add No. 11, No. 11 and No. 13 to No. 10 and dissolve at 50℃. A viscous aqueous solution is obtained. This aqueous solution No.7,

On the other hand, after mixing No. 1 to No. 6 using a Henschel mixer, the above-mentioned creamy emulsion was added and pulverized using an atomizer. Furthermore, No. 14 is added, mixed with a Henschel mixer, and then formed into a specified medium plate. The obtained foundation had good stability over time for one month, and no gaps were formed between the filling and the inner plate. In addition, water and water-soluble drugs were also contained as formulations. Furthermore, in a usage test conducted by a panel of 50 people, it was confirmed that the product had a refreshing feeling upon application and remained moisturized after application.
