Gel composition and method for producing the same, and eyelash cosmetics

Related applications

[0001] This application claims the priority of Japanese Patent Application 2005-179115 filed on June 20, 2005, and is incorporated herein.

Technical field

[0002] The present invention relates to a gel composition, a method for producing the same, a cosmetic for eyelashes, and particularly to an improvement in the thickening mechanism.

Background art

[0003] From the viewpoint of usability, handling properties, etc., thickening and gelling are performed not only in cosmetics and quasi-drugs but also in various fields such as paints and fats. As these various applications are expanded, gelling with desired physical properties is required in each of water-based, emulsified, oil-based and organic solvent-based systems. For example, in eyelash cosmetics, an oil or organic solvent system is often used to prevent the eyelashes applied to eyelashes from being easily dissolved by sweat or the like. In some cases, it may be required to apply a thick coat to make the eyelashes appear thick and long. For this reason, when applying cosmetics to eyelashes, it is necessary to apply a large amount of cosmetics to the application brush, which inevitably increases the viscosity of the cosmetics.

Conventionally, when performing oil-based gelling typified by such cosmetics for eyelashes, it has been intensive to use a polymer thickener and solid oil such as wax.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. In addition, in the following each embodiment, it describes by the mass% in principle.

First, the present inventors examined the thickening and gelling action by using a cosmetic for eyelashes having the following basic composition. In preparing the composition, unless otherwise specified, ingredients other than ethyl alcohol were mixed homogeneously, and then ethyl alcohol was added. The hardness is a hardness value at 30 ° C (card tension meter; 8mm φ Z200g load value).

As is apparent from the results in Table 1, when the gel hardness is increased with wax (Test Example 1-1), the applicability tends to be inferior although the collection property to the brush is excellent. In addition, when the nitrogen is simply replaced with an organically modified clay mineral (Test Example 12), it is difficult to extract to a brush with extremely low gel hardness. In contrast, when an organically modified clay mineral and ethyl alcohol are blended (Test Example 13), and when an organically modified clay mineral, anhydrous caustic acid and ethyl alcohol are blended (Test Example 1-4), it is appropriate. The gel hardness was achieved, and the force was very good in both sampling and coating properties. Collectability is roughly dependent on hardness. The compositions of Test Examples 3 and 4 are considered to have reduced hardness upon application due to thixotropy, and the applicability is also good. [0010] Gel formation with an organically modified clay mineral is generally achieved by swelling the organically modified clay mineral with an organic solvent. However, in Test Examples 1-3 and 1-4, the solvent that can penetrate between the layers of the organically modified clay mineral is practically only ethyl alcohol, with respect to 7-15% by mass of the organically modified clay mineral. Ethyl alcohol with a force of 4% by mass is extremely insufficient for gelling due to swelling.

Therefore, the present inventors consider that the gel compositions of Test Example 1-3 and Test Example 4 were obtained by a mechanism different from gelation due to swelling of a general organically modified clay mineral, and proceeded with further studies. It was.

[0011] Viscous minerals

In addition, as shown in Test Example 2-4, the gel-forming ability was confirmed when the organically modified clay mineral and water-free key acid were used in combination, but when the unmodified clay mineral (smetite) was used together (test) In Example 2-5), no gel-forming ability was observed, and it can be understood from this result that an organically modified clay mineral is essential.

According to the results examined by the present inventors, this organically modified clay mineral is generally used in cosmetics. Anything can be used as long as it is used.

. Specifically, it is obtained by ion exchange of an interlayer cation of a water-swellable clay mineral with a cationic surfactant such as an alkyl quaternary ammonium salt. In the present invention, the above-mentioned benzyldimethylstearyl ammonia is obtained. Especially preferred are those exchanged with humic ions, those exchanged with dimethyl distearum ammonium ions. Specific examples of water-swellable clay minerals include montmorillonite, smectite, hectorite and the like, and examples of commercially available organically modified clay minerals include Benton 27 and Benton 38 (manufactured by NL Industrie). Next, the present inventors examined the blending amount of the organically modified clay mineral. The results are shown in Table 3.

Application Δ Δ 厶 oo O Δ As shown in the results of Table 3 above, in the case of non-polar organic solvent system as in the present invention, the number of organically modified clay minerals is about 5 to 7% by mass. Noh, but in the presence of ethyl alcohol, the force increases rapidly by about 10% by mass.

In this regard, the present inventors measured the interlaminar distance of clay minerals by X-ray crystal diffraction and the like. Of course, 4% by mass of ethyl alcohol is quite insufficient for swelling organically modified clay minerals of 10% by mass or more.

Therefore, it is understood that the gelation mechanism of the gel composition of the present invention is not merely the swelling of the organically modified clay mineral.

In addition, from previous studies, organically modified clay minerals were dispersed in a nonpolar solvent, When gelling is performed with polar solvents such as alcohol, the desired gel hardness can be obtained with an appropriate blending amount. However, there is a tendency that sufficient hardness tends not to be obtained in the region where the blending amount of organically modified clay mineral is low. It was. Therefore, attention was paid to a gel composition in which an organic modified clay mineral was mixed with caustic anhydride as a dispersion, and a preferred embodiment thereof was continuously examined.

[0015] Caustic anhydride

First, caustic anhydride was examined in the system shown in Table 4.

Caustic anhydride 3: spherical silica (manufactured by Catalytic Chemical Industry Co., Ltd.)

[0016] As is clear from the results shown in Table 4 above, when caustic anhydride was mixed with the organically modified clay mineral, an appropriate hardness was obtained even when the blending amount of the organically modified clay mineral was 7% by mass. Also. It can be seen that when the average caustic anhydride chronodder is added to the gel composition according to the present invention, sufficient hardness cannot be obtained and the collection property and coating property are inferior. 16nm or less According to the results of the study by the present inventors, this caustic anhydride is generally used in cosmetics, because it has a sufficient hardness when it is in the form of fumes below. There are no particular limitations as long as it is used, and any of fumes, porous, non-porous, spherical and the like can be used, but fumed caustic anhydride is particularly preferred. Specific examples include those obtained by hydrolyzing tetrasalts in hydrogen and oxygen flames. Examples of commercially available caustic anhydrides include AEROSIL 130, 150, 200, 300, 380, 380S. It is mentioned with equal power.

Further, a hydrophobic hydrophobic caustic anhydride obtained by treating the above caustic anhydride with a reactive alkylsilane or organosilazane may be used. Hydrophobic treatment methods include dimethylsilylation treatment with dimethyldichlorosilane, trimethylchlorosilylation treatment with trimethylchlorosilane and hexamethyldisilazane, octylsilylation treatment with octyltrichlorosilane, dimethylpolysiloxane and methylhydrogenpolysiloxane. Examples include silicone treatment, surface treatment with a metal soap compound, and commercially available AEROSIL R972, R974, R976, RY200S, R202, RY200, RY300, and RA200H.

Next, the inventors conducted a simple system as shown in Table 5 to examine the blending amount of the anhydrous caustic acid mixed with the organically modified clay mineral.

^ Fabricity XXO △ OOXOOX As the results shown in Table 5 above are clear, fixing the organically modified clay mineral to 7% by mass and increasing the amount of anhydrous caustic acid gradually increases the hardness to 8% by mass. The sampling and coating properties were good. When the amount of caustic anhydride reached about 10% by mass, the hardness increased (5-6), but the collection and application properties of cosmetics tended to be inferior. Also, the blending amount of anhydrous kaiic acid is 10% by mass and the blending amount of organically modified clay mineral is 7% by mass. % And 12% by mass (5-6, 5-9) When the clay mineral is 7% by mass, the hardness is moderate, but the extractability and coatability are poor. It became so high that the measurement limit was exceeded. From this, it can be seen that the amount of caustic anhydride is preferably up to 8% by mass.

Gel-forming ability was recognized in the system containing silicate anhydride but not containing the organically modified clay mineral and ethanol (5-1) and the system containing ethanol but not containing the organically modified clay mineral (5-2). I ’m not happy.

Based on the above results, when caustic anhydride is used in combination with an organically modified clay mineral, the amount of the organically modified clay mineral is preferably 10% by mass or less. The amount of the caustic anhydride used in combination is preferably 3 to 8% by mass.

[0019] About variance ^:

Next, the present inventors examined the dispersion medium. Table 6 shows the composition of the test examples.

[0021] Fig. 1 shows the results for Test Examples 6-1 to 6-4. As is clear from the figure, the dispersion medium It is necessary to disperse the organically modified clay mineral well, and even though it is nonpolar, the silicone-based dispersion medium does not disperse the organically modified clay mineral well and gel formation is not performed. On the other hand, if it is a polar dispersion medium (ethyl alcohol), it forms a strong gel in a lump and is not in a situation where thixotropy can be expected.

Further, when the present inventors examined in detail, it was found that the proportion of the hydrocarbon-based dispersion medium in the dispersion medium was 10% by mass or more, preferably 20% by mass or more.

In addition, even when the organically modified clay minerals shown in Test Examples 7-1 to 7-4 were used in combination with caustic anhydride, the same tendency as in FIG. 1 and the above was obtained.

[0022] According to the results studied by the present inventors, the dispersion medium is preferably the isoparaffin, ex-olefin oligomer, mineral oil, squalane, hydrogenated polyisobutene, polybutene, or the like. In addition, although it is not preferable as a dispersion medium by itself, it can be combined with the above isoparaffins, etc., so that it can be combined with low-polymerization dimethylpolysiloxane, high-polymerization dimethylpolysiloxane, methylphenol polysiloxane, polyether-modified organopolysiloxane. Silicone solvents such as hexane, amino-modified silicone, fluorine-modified dimethylpolysiloxane, fluorine-modified methylphenol polysiloxane, cetyl-2-ethylhexanoate, 2-ethylhexyl palmitate, 2-octyldodecyl myristate, Neopentyl glycol 2-ester, hexylhexanoate, isopropyl myristate, myristyl myristate, olive oil, avocado oil, jojoba oil, castor oil, safflower oil, coconut oil, macadamia nut oil, mink oil, liquid Phosphorus, lanolin acetate, although such as oil castor oil, and the like, the dispersion medium is generally in cosmetics is not intended to be restricted to the as long as it is used in a combination.

[0023] Polar solvent

Furthermore, the inventors of the present invention do not substantially gel with organically modified clay minerals, or organically modified clay minerals and only anhydrous silicic acid, and exhibit excellent properties when ethyl alcohol is added to the dispersion. We paid attention and examined the relationship.

First, when the amount of ethyl alcohol and the gelling action were examined using the simple system shown in Table 8 below, the results shown in Fig. 2 were obtained.

As apparent from FIG. 2, there is almost no gel-forming ability up to about 1% by mass of ethyl alcohol, but it shows a sharp rise at about 3% by mass, and the hardness increase thereafter becomes small. It can be understood that such a phenomenon exhibits a high gel-forming ability of about 3% by mass of ethyl alcohol with respect to 10% by mass of the organically modified clay mineral. In addition, when the organically modified clay minerals shown in Test Examples 91 to 94 were used in combination with caustic anhydride, the same tendency as in FIG. 2 and the above was obtained.

[0026] Next, the present inventors examined the types of polar solvents that impart gel-forming ability.

In addition, even when the organically modified clay minerals shown in Test Examples 11-1 to 11-5 were used in combination with caustic anhydride, the same tendency as in FIG. 3 and the above was obtained.

[0029] Furthermore, the present inventors examined combinations of ethyl alcohol, which is safe and easy to handle, with a main polar solvent and other polar solvents. The composition is shown in Table 12 and the results are shown in Figure 4. The

In particular, when the composition is used for cosmetic applications, it is preferable to use it in combination with 1,3-butylene glycol, which is widely used as a humectant, and water is preferable from the viewpoint of improving the gel hardness.

In addition, when the organically modified clay minerals shown in Test Examples 13-1 to 13-5 were used in combination with caustic anhydride, the same tendency as in FIG. 4 and the above was obtained.

[0032] Further, the present inventors investigated the gelation ability by replacing part of ethyl alcohol with ion-exchanged water. Ion-exchanged water has virtually no interlayer swelling and thickening effect of organically modified clay minerals

In addition, the same tendency was obtained in the composition shown in Table 15 in which the organically modified clay mineral and caustic anhydride were used in combination.

[0034] As a result of the above examination, as long as the organically modified clay mineral and the anhydrous key acid are dispersed in the non-polar dispersion medium, some degree of gelling ability or thickening effect is observed in any polar solvent. High molecular weight and high polarity have high gely ability. Water is difficult to disperse or dissolve well in a nonpolar dispersion medium, and when used together with other organic polar solvents, high gelling ability can be exhibited. In addition, when the gel composition according to the present invention is used in eyelash cosmetics, the curling effect is lowered, and from this point of view, it is preferable to use it together with other organic polar solvents other than water.

Considering the high level of gelity and safety, ethyl alcohol power S is most preferable. In addition, if ethyl alcohol is included in an amount of about 2% by mass, even if other polar organic solvents are used in combination, a good gelling ability can be obtained as a whole.

In addition, when both the organically modified clay mineral and the anhydrous key acid are contained, it is possible to maintain good hardness even in a system that does not contain water. It is understood that this is a prescription.

[0035] Iron making method

Using the basic formulation of Test Example 7-3 in Table 7 above, (1) When ethyl alcohol is added to an organically modified clay mineral or a mixture of an organically modified clay mineral and carboxylic anhydride, and then a nonpolar dispersion medium is added,

(2) When ethyl alcohol is added to a nonpolar dispersion medium, and an organically modified clay mineral or a mixture of an organically modified clay mineral and caustic anhydride is added thereto; and

(3) When an organically modified clay mineral or a mixture of an organically modified clay mineral and caustic anhydride is dispersed in a nonpolar dispersion medium and ethyl alcohol is added thereto,

The gel state of this!

As a result, in the case of (1), the clay mineral partially formed a strong lump gel and did not become a homogeneous system.

In the case of (2), although the gel formation occurred, the clay mineral could not be uniformly dispersed.

From the above points, a preferable production method in the present invention is to add a polar solvent after dispersing an organically modified clay mineral or a mixture of an organically modified clay mineral and an anhydrous key acid in a nonpolar dispersion medium. I understand that.

Next, the present inventors prepared eyelash cosmetics using the gel composition according to the present invention. The eyelash cosmetics were evaluated as follows.

(1) Long rush effect

Each sample (mascara) was applied 10 times to the eyelashes by 20 specialist panels, and the length of the eyelashes before and after application was observed with a microscope and evaluated by the relative value of the length.

(2) The beauty of the finish (the degree of fiber blending in the same direction as the eyelashes)

Each sample (mascara) was applied 10 times to eyelashes by 20 specialist panels, and the eyelashes after application were observed with a microscope, and the eyelashes were evaluated by counting the number of fibers protruding. The smaller the value, the better the finish.

[0037] First, the present inventors examined the coating amount and finish in a system that was gelled with wax.

[0038] Fig. 5 shows the coating amount, and Fig. 6 shows the finish. Comparing Fig. 5 and Fig. 6, it can be understood that the coating amount increases as the hardness of the sample increases, but the finish quality decreases due to the occurrence of "worm feet".

Therefore, the present inventors increased the viscosity with a gel so that the hardness decreases greatly when applied to eyelashes, which has a high hardness when collected on a brush.

As shown in FIG. 7, the gel according to the present invention is thickened and cured by a high dispersion force, but rather has a property that the hardness is remarkably lowered when a low dispersion force is applied. Therefore, when preparing the composition, the hardness is increased by a high dispersion force to improve the collection property to the brush, and at the time of application, the hardness is decreased by the low dispersion force associated with the application operation, thereby improving the applicability and finish. -ing

[0039] Next, when gelled with a wax, when gelled with an organically modified clay mineral and ethyl alcohol, or when a mixture of an organically modified clay mineral and caustic anhydride is gelled with ethyl alcohol, The cosmetic properties were examined with the same hardness.

Hardness £ 8 28 11 Figure 8 shows the finish and long lash effect of these eyelash cosmetics. As can be seen from the figure, even when adjusted to the same hardness, the eyelash cosmetics according to the present invention clearly showed excellent long lash effect and finish.

[0040] It should be noted that the fiber used in the eyelash cosmetic according to the present invention is blended in order to impart a long lash effect that makes the eyelash look longer, and is particularly limited as long as it is generally used in cosmetics. Of these, synthetic fibers such as nylon and polyester, artificial fibers such as rayon, and natural fibers such as cellulose are preferable. Further, it is more preferable that the hollow fiber has a modified cross section. Here, the irregular cross-section hollow fiber has a cross section other than a circle or an ellipse. The fiber cross section has a triangular shape, a quadrangular shape, a pentagonal shape, a polygonal shape, and other specific shapes, and the inside is a continuous hollow fiber. A fiber having a depression that can be oriented to the eyelashes on the outer periphery of the fiber cross section (the portion corresponding to the side of the polygon connecting each vertex) is preferable. The depression that can be blended into the eyelashes preferably has a shape in which each side of the polygon of the cross section is recessed in an arc. This indentation dramatically improves the orientation of the irregular cross-section hollow fibers (fibers attached in the same direction as the eyelashes) and improves the long lash effect. In addition, the phenomenon in which the fibers stick to the eyelashes in the lateral direction and stick out is suppressed, and the beautiful finishing effect is dramatically improved.

[0041] The fiber material is not particularly limited as long as it is a synthetic fiber that can be hollow processed. Specifically, synthesis of nylon, polyester, polypropylene, rayon, cupra, acetate, triacetate, acrylic, polyurethane, vinylon, promix, vinylon, polynosic, etc. Fiber. Particularly preferred fiber materials are nylon and polyester. The modified cross-section hollow fiber used in the present invention is produced by a known method in which a synthetic fiber is spun using a spinneret designed in an arbitrary shape. The hollowness (void ratio) is preferably about 10% from the viewpoint of designing the spinneret nozzle. The hollow structure is not limited, but the cross section is preferably circular.

[0042] The length of the modified cross-section hollow fiber is preferably 1 to 4 mm, and more preferably 2 to 3 mm. Below 1mm, the effect of making the eyelashes look longer is poor. If it exceeds 4 mm, it will be difficult to produce natural eyelashes, and it will be difficult to apply eyelash cosmetics containing these.

It should be noted that when it has a triangular, quadrangular, or pentagonal cross section, 2 to 3 mm is superior to 4 mm in the long lash effect, and the most preferable length is around 2 mm.

[0043] The thickness of the irregular cross-section fiber is preferably 20 to 50 m, and more preferably 30 to 4 O / z m. If it is less than 20 m, it is difficult to orient straightly to the eyelashes where the fibers are stiff, and if it exceeds 50 m, it is difficult to produce natural eyelashes, which makes it difficult to produce natural eyelashes. Therefore, it is difficult to apply the eyelash cosmetic containing the same. Most preferably, it is 40 m in pentagonal irregular cross-section fiber.

The content of the modified cross-section fiber is preferably 0.5 to 8.0% by mass, more preferably 1 to 7% by mass, based on the total amount of the cosmetic for eyelashes. Less than 5 mass%, the effect of making the eyelashes look longer is poor. On the other hand, when it exceeds 8.0% by mass, it is difficult to produce natural eyelashes, and it is difficult to apply a cosmetic for eyelashes containing this.

[0044] The irregular cross-section fiber may be a fiber dyed in any color! / ヽ. In addition, various surface treatments may be applied as required! / ヽ.

It is not necessary to add wax to the eyelash cosmetic of the present invention for the purpose of thickening and curing. When wax is added, the relationship power, such as gloss, is preferably 3% by mass or less, particularly preferably 1% by mass or less.

[0045] The eyelash cosmetic of the present invention preferably contains a film-forming rosin. Specifically, polybulualcohol, polybulupyrrolidone, polybutyric acetate, polyalkyl acrylate Latexes such as dextrin, cellulose derivatives such as dextrin, alkylcellulose and -trocellulose, trimethylsiloxykey acid, trimethylsiloxysilylpropylcarbamic acid, fluorine-modified silicone, acrylic silicone and other silicone resins are used. One or two or more of these are selected and used. Among these, KF7312J, X-21-5250 (both manufactured by Shin-Etsu Silicone Co., Ltd.) and the like can be used as commercially available products in which trimethylsiloxykeic acid is particularly preferred.

[0046] The amount of film-forming rosin (solid content) to the eyelash cosmetic is appropriately adjusted, but is preferably 1 to 25.0 mass%, more preferably 2.0 to 20 mass%. is there. If the blending amount is less than 0.1% by mass, the curling maintenance effect may be reduced and the secondary adhesion between fibers may occur. Also, from the viewpoint of fiber adhesion, fibers may fall off if the film forming resin is small. On the other hand, if the blending amount exceeds 25% by mass, it is not preferable because it is applied to the coating.

[0047] It is preferable that a colorant is blended in the eyelash cosmetic of the present invention. The color material is not particularly limited as long as it is generally used for makeup cosmetics. For example, talc, my power, kaolin, silica, calcium carbonate, zinc white, titanium dioxide, red iron oxide, yellow iron oxide, black iron oxide, ultramarine, bitumen, carbon black, low-order titanium oxide, conoretio violet, acid Inorganic pigments such as chromium, chromium hydroxide, cobalt titanate, bismuth oxychloride, titanium myrium-based purple pigments; red 201, red 202, red 204, red 205, red 220, red 226 Organic pigments such as zirconium, barium or aluminum lake such as Red 228, Red 405, Orange 203, Yellow 205, Yellow 4, Yellow 5, Yellow 1, Blue 404, Green 3; Natural pigments such as chlorophyll and / 3 striking rotin; dyes. These coloring materials can be used alone or in combination of two or more.

[0048] The blending amount of the coloring material is appropriately adjusted. The content is preferably 0.1 to 30% by mass, and more preferably 3 to 20% by mass. If it exceeds 30% by mass, it is not preferable in terms of adhesion. If the amount is less than 1% by mass, the effect of the coloring material may be insufficient.

The eyelash cosmetic of the present invention can be blended with a thickener in a wrinkle range where applicability is not deteriorated. Examples of the thickener include dextrin fatty acid ester, xanthan gum, and cellulose gum. One or more of these thickeners are selected and used.

The blending amount of the thickener is appropriately adjusted according to the desired viscosity. Preferably 0.1-30 quality % By weight, more preferably 1 to 20% by weight. If the blending amount is less than 0.1% by mass, it may be difficult to prepare for a matchmaker. On the other hand, if the blending amount exceeds 30% by mass, the hardness becomes too high and smoothness may be lacking.

[0049] In the present invention, a cosmetic for eyelashes can be produced by blending the above components by a conventional method.

Ingredients that can usually be added to makeup cosmetics may be added within a quantitative and qualitative range that does not impair the effects of the present invention. Examples of such components include alcohols, polyhydric alcohols, drugs, surfactants, successful Wednesday molecules, powders, preservatives, fragrances, antioxidants, UV absorbers, humectants, fats and oils, hydrocarbons. Oily components such as oil can be mentioned.
