Abstract
Description
[Technical field]
[0001] The present invention relates to an oily stick-type cosmetic preparation and a method for producing the same. [Background technology]
[0002] The main effects required for oil-based stick-type cosmetics are, for example, lip cosmetics that give a color to the lips and give a healthy impression through the color, and cosmetics that give a three-dimensional effect to the mouth and make them stand out beautifully. In addition, ease of use when applying to the lips is also a very important factor in finishing an ideal cosmetic film. In particular, the surface of the lips is soft and it is difficult to apply cosmetics to the lips, so it is required that the cosmetics spread smoothly and easily when applied. In addition to these qualities, in recent years, the number of opportunities to put on and take off masks has increased from the perspective of preventing infectious diseases, and a secondary adhesion-free effect that prevents the cosmetics from physically adhering to other substances is required, and among them, lip cosmetics that can quickly exert a secondary adhesion-free effect after the cosmetics are applied to the lips are very popular. When the secondary adhesion-free effect is exerted, the silicone oil in the cosmetic application film separates to the upper layer after the lip cosmetics are applied and coats the surface of the cosmetic application film, thereby exerting the effect.
[0003] To date, a lip cosmetic has been proposed that combines hydrogenated polyisobutene, one or more types of methylphenyl silicone that separate when mixed with hydrogenated polyisobutene at 25°C, a lipophilic surfactant that does not separate when mixed with either of the above two types at 90°C, and a specific amount of wax, which has an excellent secondary adhesion-resistant effect immediately after application, maintains shine after application, and is also highly stable (see, for example, Patent Document 1).
[0004] In addition, a method has been proposed that includes a step of combining a first fluid containing one or more solid oily components at 25°C with a second fluid containing one or more components that are incompatible with the components contained in the first fluid inside a vibration-type stirring mixer or immediately before said device to obtain a mixed liquid, thereby enabling the stable production of oil-based solid cosmetics containing incompatible or unstable components (see, for example, Patent Document 2).

[0005] [Patent Document 1] JP 2011-140481 A [Patent Document 2] JP 2015-124204 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]
[0006] However, when the separation speed of the cosmetic coating film is increased to quickly exert the secondary adhesion-free effect, separation is likely to progress during the manufacturing process of the oil-based stick-type cosmetic, resulting in a non-uniform cosmetic. In addition, when color retention and secondary adhesion-free properties are simultaneously achieved, releasability may deteriorate when molding into a stick shape. Therefore, there has been a demand for an oil-based stick-type cosmetic that has excellent qualities in terms of color retention, smooth spreadability, and the speed of the secondary adhesion-free effect, while suppressing separation during the cosmetic manufacturing process and having excellent releasability when filled. For example, as in the technology of Patent Document 1, there has been an idea to maintain quality by combining materials that prevent layer separation of oily agents that tend to separate, but the speed at which the secondary adhesion-reducing effect occurs is slow, and no oil-based cosmetic products with excellent noticeable effects have been developed. In addition, for example, as in Patent Document 2, there have been efforts in the past to use a vibration-type stirring and mixing device to mix a component contained in a first fluid with a second fluid containing one or more incompatible components, but there was no focus on the issue of separating the component from the colorant, nor was there any focus on solving the problem by devising the order of addition of the colorant.
[0007] In other words, an object of the present invention is to provide a method for producing an oily stick-shaped cosmetic preparation that has excellent quality in terms of color retention, smooth spreadability, and speed of secondary adhesion-free effect, while suppressing separation during the cosmetic preparation production process and having excellent releasability when filled.

BEST MODE FOR CARRYING OUT THEINVENTION
[0012] Preferred embodiments of the present invention will be described in detail. However, the present invention is not limited to the following preferred embodiments, and can be freely modified within the scope of the present invention. In this specification, percentages are expressed by mass unless otherwise specified. In addition, in this specification, when a numerical range is expressed using "~", the range includes both ends of the numerical range.
[0013] The melting point in the present invention is defined as the melting point (Tm) defined as the peak top of the peak observed on the highest temperature side of the melting endothermic curve measured by using a differential scanning calorimeter (DSC) by holding a sample at -10°C for 5 minutes under a nitrogen atmosphere and then heating at a rate of 10°C / min.
[0014] In the present invention, the viscosity at 25°C (mPa·s) = (CSt: centistokes) is calculated by filling a measurement sample into a glass bottle with an outer diameter of 45 mm, an inner diameter of 38 mm, and a height of 82 mm without leaving any air spaces, covering it, and leaving it in a thermostatic chamber at 25°C for a whole day and night.Then, using a single-cylinder rotational viscometer Vismetron (registered trademark) (manufactured by Shibaura Systems Co., Ltd.) (B-type viscometer) with the attached rotors No. 1 to 4, the measurement value after 1 minute was read at 0.3 to 30 rpm, and multiplied by the respective multipliers. Viscosity indicates the difficulty of an object moving in a fluid, while kinetic viscosity (mm 2 / s) represents the difficulty of the fluid itself to move, and the factors that affect this difficulty are the density of the object and the kinetic viscosity (mm 2 / s) = viscosity (mPa s) / density.

[0043] In addition to the above-mentioned components (A) to (G), the oily stick-shaped cosmetic preparation of the present invention may contain components that are usually used in cosmetics, such as oily components other than the components (B), (C), and (F), surfactants, fibers, alcohols, oily solidifying agents other than the component (A), water-soluble polymers, resinous film-forming agents other than (G), aqueous components such as moisturizers other than component (E), sugars, antioxidants, antifoaming agents, cosmetic ingredients, preservatives other than component (E), fragrances, etc., within the range that does not impair the effects of the present invention.
[0044] The oily stick-shaped cosmetic preparation of the present invention can be produced by the following method. Specifically, the method includes a step of dissolving component (A) at a temperature equal to or higher than the melting point thereof, and then components (C) and (D) are uniformly mixed at a temperature equal to or higher than the melting point of component (A), and then component (B) is added to the mixture, which is then filled into a container, but is not limited to this manufacturing method. As for the preferred steps, the manufacturing method is a method for manufacturing an oily stick-type cosmetic preparation having the following steps 1 to 4, and specifically, Step 1: melting the component (A) at a temperature equal to or higher than the melting point of the component (A), and adding and mixing the components (C) and (D); Step 2: (2-1) A step of dispersing the mixture obtained in the step 1 at 5 to 80°C, and further adding and dispersing the component (B) at 30 to 110°C to obtain a cosmetic composition; or (2-2) a step of adding the component (B) to the mixture obtained in the step 1, and dispersing the mixture at 30 to 110°C to obtain a cosmetic composition; (However, the component (E) is added, mixed or dispersed in step 1 and / or step 2.) Step 3: Heating the cosmetic composition obtained in step 2 at 80 to 110°C and filling the composition into a container while stirring. Step 4: Cooling the cosmetic composition filled in the container obtained in step 3. The temperature in step 1 is not particularly limited as long as it is equal to or higher than the melting point of component (A), but for example, 70 to 130°C is preferred, and 80 to 110°C is more preferred. In step 1, components (B) and (C) may be mixed with component (A) separately, but it is preferred to mix components (C) and (D) in advance and then add and mix with component (A). This process is preferred because it provides excellent color retention, smooth spreadability, and secondary adhesion resistance. Thus, in step 1, it is necessary to mix components (A), (C), and (D), and if component (D) is not added in step 1, for example, it may be inferior in terms of preventing separation in the process. The equipment used in the dispersion treatment of the mixture in step (2-1) of step 2, the further dispersion treatment after adding component (B), and the dispersion treatment after adding component (B) to the mixture in step (2-2) is not particularly limited as long as it is a dispersion equipment usually used in the production of cosmetics, but examples thereof include media dispersers such as Henschel mixers, kneaders, bead mills and ball mills, media-less nano high pressure dispersers, stone mill grinders, roll mills, homogenizers, Ajidespa, triple mixers, ultra mixers, high viscosity mixers, and other equipment utilizing self-rotation and revolution, and media dispersers such as bead mills and ball mills, media-less nano high pressure dispersers, stone mill grinders, and roll mills are preferred. Among these, high shear dispersion treatment using equipment that performs high shear dispersion treatment is preferred. As equipment that performs high shear dispersion treatment, media dispersers such as bead mills and ball mills, media-less nano high pressure dispersers, stone mill grinders, roll mills, and equipment utilizing self-rotation and revolution are more preferred. Such a process is preferable because it provides excellent color retention and smooth spreadability. It is important that the oily stick cosmetic of the present invention has a high rate of manifestation of the secondary adhesion-free effect, but it is also important that after application of the oily stick cosmetic, component (B) rapidly separates onto the surface of the applied film, and the phase containing components (A), (C), and (D) rapidly moves to the vicinity of the skin. However, if the components are separated during the process, this affects the smooth spreading during use, the releasability during filling, and the stability over time, so it is preferable that they are mixed more uniformly during the process, and it is preferable to devise a method in step 2 in order to simultaneously satisfy the opposing effects. Specifically, step (2-1) is a step of adding component (B) at a specific temperature into the oil phase in which component (D) has been uniformly dispersed in advance, and component (B) is mixed evenly afterwards, but step (2-1) is preferable from the viewpoint of preventing separation during the process. The temperature at which component (B) is added in step (2-1) is 30 to 110°C, preferably 60 to 110°C, and more preferably 60 to 90°C. This range is preferable because it does not promote re-aggregation of the oil phase components containing component (D) due to poor compatibility between component (B) and other components, the secondary adhesion-free effect is achieved quickly, and it is possible to prevent separation of the components during processing and achieve releasability.In step (2-1), the temperature at which the mixture obtained in step 1 is dispersed is from 5 to 80°C, and more preferably from 10 to 60°C. Component (E) may be added, mixed or dispersed in either step 1 or step 2, or in both steps 1 and 2, but adding and mixing in step 1 is preferred because it provides better color retention and smoother spreadability. When component (F) is used, it may be added, mixed or dispersed in either step 1 or step 2, or in both steps 1 and 2, but adding and mixing in step 2 is preferred because it provides better smoother spreadability. Regarding the container in step 3, it is possible to fill the oil-based stick-type cosmetic preparation into a rubber molded container, a metal molded container, a plastic container, etc., but a rubber molded container or a metal molded container is preferred, and a rubber molded container is more preferred. This step is preferred because it provides excellent releasability when filling the oil-based stick-type cosmetic preparation and excellent stability over time. In addition, there is no limitation on the inclusion of components other than those described in each step. In step 4, the cosmetic composition filled in the container in step 3 is cooled and solidified. The temperature is not particularly limited, but is, for example, about -20 to 0°C.
[0045] The oily stick cosmetic composition of the present invention is not particularly limited as long as it is solid, and can be used for lip cosmetics such as lipstick and lip gloss, foundation, concealer, eyeliner, eye color, blush, etc. In particular, the good color retention and smooth spreadability of the oily stick cosmetic composition of the present invention make it suitable for use in lip cosmetics, which are often applied to the lips by smoothly applying to soft areas that are frequently moved on a daily basis.

[0070] (2) Prevention of separation during the process As for prevention of separation during the process, the separation immediately before filling was evaluated by dissolving the stick-shaped cosmetic preparations of the above Examples and Comparative Examples at 110°C, filling 50 g of the preparation into a cylindrical glass bottle with a diameter of 4 cm and a height of 8 cm, and observing the state after leaving it to stand for 10 minutes while continuing to apply heat, and judging according to the following criteria. These evaluations enable verification of the separation behavior of the oil and coloring material during the actual manufacturing process. (In-process separation prevention judgment criteria) (Judgment): (Evaluation) AA: No oil separation or uneven coloring observed in cosmetics A: The color of the cosmetic is slightly uneven and separated, but it can be homogenized by shaking once. Becoming One B: The cosmetic has uneven color and separation, but it becomes homogenous after shaking twice. R C: Separation was observed in the cosmetic material and it was not uniform even after shaking twice. D: A lot of separation has occurred in the cosmetic material.

However, the level is unacceptable in terms of the appearance quality of the product (the (The percentage of people with HIV infection is less than 5-10%) D: Significant peeling, cracks, breaks, or chips are observed, affecting usability. Bell (occupies 10% or more of the appearance)
[0072] As is clear from the results in Tables 1 to 5, the oily stick lipsticks of Examples 1 to 47 of the present invention were superior in color retention, smooth spread, speed of secondary adhesion-free effect, prevention of separation in processing, and releasability, compared to the oily stick lipsticks of Comparative Examples 1 to 4. On the other hand, Comparative Example 1, which did not contain component (A), lacked color retention, smooth spreading, secondary adhesion-free effect speed, and releasability, and was therefore unsatisfactory. Moreover, in Comparative Example 2, which did not contain component (B), color retention, smooth spreading, secondary adhesion-free effect speed, and releasability were lacking, and a satisfactory product was not obtained. Moreover, in Comparative Example 3, which did not contain the component (C), the color retention, smooth spreading, secondary adhesion-free effect speed, and releasability were lacking, and a satisfactory result was not obtained. Furthermore, in Comparative Example 4, which did not contain the component (E), the smooth spreading and the speed of the secondary adhesion-free effect were lacking, and a satisfactory result was not obtained.
[0073] As is clear from the results in Table 6, the oily stick lipsticks of Examples 1 and 1-8 of the present invention were far superior in color retention, smooth spreading, secondary adhesion-free effect speed, in-process separation prevention, and releasability compared to the oily stick lipsticks of Examples 1-2 to 1-7 and 1-9 to 1-12. In particular, Example 1 also had a desirable surface pattern. In Example 1-2 of Production Method 2, since components (C) and (D) were not brought into contact with each other in advance, there was a tendency for color retention to be slightly reduced, but the product was extremely excellent in terms of smooth spreading, the speed of the secondary adhesion-free effect, prevention of separation during processing, and releasability. In Examples 1-3 of Production Method 3, because the temperature at which component (B) was added was high, the fluidity of the product produced in Step 1 increased and the viscosity decreased, making components (B) and (D) more likely to come into contact with each other and making separation during the process a little easier. However, the product was extremely excellent in color retention, smooth spreadability, speed of the secondary adhesion-free effect, and releasability. In Examples 1-4 of Production Method 4, because the temperature at which component (B) was added was low, the viscosity of the product produced in step 1 was high, and component (B) was difficult to mix. Since the component (B) was not mixed uniformly, separation was somewhat likely to occur during the process, and smooth spreadability tended to decrease slightly. However, the product was extremely excellent in color retention, the speed of the secondary adhesion-free effect, and releasability. In Examples 1-5 of Production Method 5, component (F) is added in step 1 rather than step 2. Although there was a tendency for smooth spreading to decrease slightly, the color retention, the speed of the secondary adhesion-free effect, the prevention of separation during processing, and the releasability were excellent. In Examples 1-6 of Production Method 6, the temperature at which component (F) is added in step 2 is lowered. As the viscosity of the previous composition increases, component (F) is less likely to be mixed uniformly, and there is a slight tendency for the continuous wax crystal structure of components (A) to (E) to be destroyed. However, the results were excellent in terms of color retention, the speed of the secondary adhesion-free effect, and prevention of separation during the process. In Examples 1-7 of Manufacturing Method 7, component (E) was added from step 1 to step 2. Although the color retention effect was slightly reduced due to contact between components (D) and (E), the product was extremely excellent in terms of smooth spreading, the speed of the secondary adhesion-free effect, prevention of separation during processing, and releasability. In Examples 1-9 of Manufacturing Method 9, the container was changed in step 3. Although this affected the smooth spreading due to the release properties, the color retention, the speed of the secondary adhesion-free effect, and the prevention of separation during the process were excellent. Examples 1-10 of Manufacturing Method 10 used different dispersion equipment in Step 2. Although color retention was slightly affected by the influence of component (D), the smooth spreading, the speed of the secondary adhesion-free effect, the prevention of separation during the process, and the releasability were excellent. In Examples 1-11 and 1-12 of Production Method 11, since component (B) is added beforehand and then dispersed in Step (2-2) instead of in Step (2-1) where component (B) is added later in Step 2, the dispersed component (D) is expelled by component (B) during dispersion, which tends to promote separation within the process and may also affect releasability. Furthermore, Example 1-12 of Production Method 12, in which component (F) is added before Step 2, also tends to reduce color retention and smooth spreadability, but the speed of the secondary adhesion-free effect was maintained.
