Description

Technical Field

[0001] The invention relates to an oily stick-shaped cosmetic and a method for producing the same. Background Art

[0002] The main effects sought for oily stick cosmetics are, for example, in the case of lip cosmetics, the effect of giving color to the lips and giving a healthy impression based on the color; or the effect of giving a three-dimensional sense to the lips, making them beautiful and eye-catching. In addition, in terms of completing an ideal cosmetic film, the usability when applied to the lips is also a very important factor. In particular, the lips are a part with a soft surface and it is not easy to apply cosmetics, so it is required to spread smoothly and easily when applied. In addition to these qualities, in recent years, from the perspective of preventing infectious diseases, the chances of wearing / removing masks have increased, and the effect of preventing cosmetics from physically adhering to other substances is also sought. Among them, lip cosmetics that can quickly exert the effect of no secondary adhesion after applying cosmetics to the lips are very popular. When exerting the effect of no secondary adhesion, after applying lip cosmetics, the silicone oil in the cosmetic coating film is separated to the upper layer, and its effect can be exerted by covering the surface of the cosmetic coating film.

[0003] Hitherto, lip cosmetics have been proposed which are a combination of hydrogenated polyisobutene, one or more methylphenyl silicones which separate when mixed with hydrogenated polyisobutene at 25°C, a lipophilic surfactant which does not separate when mixed with the two at 90°C, and wax in specific amounts, and which have an excellent non-secondary adhesion effect immediately after application, and which have a persistent gloss after application and are also excellent in stability (for example, see Patent Document 1).

[0004] In addition, a method for stably producing an oily solid cosmetic containing incompatible or unstable components is proposed, the method comprising the following steps: a first fluid containing one or more oily components that are solid at 25° C. and a second fluid containing one or more components that are incompatible with the components contained in the first fluid are combined in a vibrating stirring and mixing device or immediately before the device to obtain a mixed liquid (for example, refer to Patent Document 2).

[0008] Patent document 2: Japanese Patent Application Publication No. 2015-124204. Summary of the invention

[0009] Problems to be solved by the invention

[0010] However, if the separation speed of the cosmetic coating film is increased to quickly exert the effect of no secondary adhesion, the separation is also easy to occur during the manufacturing process of the oily stick cosmetic, resulting in uneven cosmetics. In addition, if both color durability and no secondary adhesion are taken into account, the demoulding property may be poor when molded into a stick. Therefore, an oily stick cosmetic is sought that has excellent qualities of color durability, smooth spreading, and speed of no secondary adhesion effect, while suppressing the separation of the cosmetics during the manufacturing process and having excellent demoulding property during filling.

[0011] For example, as shown in the technology of Patent Document 1, attention has been paid to maintaining quality by combining raw materials that prevent the oily agent layer from separating easily, but the speed at which the secondary adhesion effect disappears is slow, and oily cosmetics with excellent effect reality have not been developed.

[0012] In addition, for example, as shown in Patent Document 2, in the past, studies have been conducted on the process of using a vibrating stirring and mixing device to deal with components contained in a first fluid and a second fluid containing one or more incompatible components, but no attention has been paid to the issue of separation from the colorant, nor has attention been paid to solving the problem by studying the order of addition of the colorant.

[0101] The oily stick cosmetic of the present invention can be produced by the following production method.

[0102] Specifically, the step of dissolving component (A) at a temperature above the melting point may be included, and a mixture obtained by uniformly adding and mixing components (C) and (D) at a temperature above the melting point of the component (A) and component (B) may be added and filled into a container, but the method is not limited to this method. Regarding preferred steps, the method is a method for producing an oily stick cosmetic having the following steps 1 to 4, specifically, the method has the following steps:

[0103] Step 1: a step of dissolving the component (A) at a temperature above the melting point of the component (A), adding the component (C) and the component (D) and mixing them;

[0104] Step 2: Step (2-1) The mixture obtained in the above step 1 is dispersed at 5 to 80° C., and the above component (B) is added and dispersed at 30 to 110° C. to obtain a cosmetic composition; or

[0105] Step (2-2) adding the above-mentioned component (B) to the mixture obtained in the above-mentioned step 1, and dispersing it at 30 to 110° C. to obtain a cosmetic composition;

[0106] (wherein the above-mentioned component (E) is added, mixed or dispersed in step 1 and / or step 2)

[0107] Step 3: heating the cosmetic composition obtained in the above step 2 at 80 to 110° C. and filling the mixture into a container while stirring;

[0108] Step 4: A step of cooling the cosmetic composition filled in the container obtained in the above step 3.

[0109] The temperature in process 1 is not particularly limited as long as it is a temperature above the melting point of component (A), and is preferably 70 to 130°C, and more preferably 80 to 110°C. In addition, in process 1, components (B) and (C) can be mixed with component (A) separately, but it is preferred to mix component (C) and component (D) in advance and then add and mix with component (A). Through such a process, color durability, smooth spreading, and no secondary adhesion effects are excellent, so it is preferred. In this way, it is necessary to mix component (A) and components (C) and (D) in process 1. For example, when component (D) is not added in process 1, the viewpoint of preventing separation within the process may sometimes be deteriorated.

[0110] About the dispersion treatment of the mixture in the process (2-1) of process 2, the dispersion treatment after further adding component (B), the equipment used in the dispersion treatment after adding component (B) to the mixture in process (2-2), as long as it is a dispersion equipment for manufacturing ordinary cosmetics, it is not particularly limited, and can be listed: Henschel mixer, kneader, media dispersion machine such as bead mill / ball mill, medium-free nano high-pressure dispersion machine, stone mortar type grinding machine, roller mill, homogenizer, アジデスパー, triple mixer, super mixer, high viscosity mixer, etc., effectively utilize the equipment of self-rotation revolution, preferably media dispersion machine such as bead mill / ball mill, medium-free nano high-pressure dispersion machine, stone mortar type grinding machine, roller mill. Among them, it is preferred to use the high shear dispersion treatment of the equipment for high shear dispersion treatment. As the equipment for high shear dispersion treatment, more preferably media dispersion machine such as bead mill / ball mill, medium-free nano high-pressure dispersion machine, stone mortar type grinding machine, roller mill, effectively utilize the equipment of self-rotation revolution. Such a process is preferred because the color durability and smooth spreading are excellent. It is important that the oily stick cosmetic of the present invention has a fast speed of manifestation of the non-secondary adhesion effect, but it is more important that the component (B) is quickly separated to the surface of the coating film after applying the oily stick cosmetic, and the phase containing the component (A), the component (C), and the component (D) quickly moves to the vicinity of the skin. However, in the case of a state of separation within the process, it affects the smooth spreading during use, the demoulding property during filling, or the stability over time. Therefore, it is preferred to mix more uniformly within the process. In order to simultaneously satisfy the opposite effects, it is preferred to work hard in process 2. Specifically, process (2-1) is a process of adding component (B) to the oil phase in which component (D) is uniformly dispersed at a specific temperature, and it is a process of mixing after component B is uniform, but from the viewpoint of preventing separation within the process, process (2-1) is preferred. It should be noted that the addition temperature of component (B) in process (2-1) is 30 to 110°C, preferably 60 to 110°C, and more preferably 60 to 90°C. If it is within this range, since the compatibility of component (B) with other components is poor, the re-agglomeration of the oil phase components including component (D) is not promoted, the speed of the secondary adhesion effect is fast, and the prevention of component separation in the process and mold release properties can be achieved, which is preferred. In the step (2-1), the temperature when dispersing the mixture obtained in the step 1 is 5 to 80°C, more preferably 10 to 60°C.

[0111] Component (E) may be added and mixed or dispersed in either step 1 or step 2, or in both steps 1 and 2. However, adding and mixing in step 1 is preferred because it is more excellent in color durability and smooth spreading. When component (F) is used, it may be added and mixed or dispersed in either step 1 or step 2, or in both steps 1 and 2. However, adding and dispersing in step 2 is preferred because it is more excellent in smooth spreading.

[0112] The container in step 3 can be filled into a rubber mold container, a metal mold container, a plastic container, etc., but a rubber mold container or a metal mold container is preferred, and a rubber mold container is more preferred. By such a step, the oily stick cosmetic has excellent mold release properties during filling and excellent stability over time, which is preferred.

[0113] In addition, in each process, there is no limitation on the inclusion of other components other than the components described.

[0114] In step 4, the cosmetic composition filled into the container in step 3 is cooled to solidify. The temperature is not limited, but is, for example, about -20 to 0°C.

[0115] The oily stick cosmetic 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 shadow, blush, etc. Among them, the oily stick cosmetic of the present invention has good color durability and good smooth spreading, and can be suitably used for various lip cosmetics, and the lip cosmetics can be used as cosmetics for lips by smoothly applying to parts that are frequently moved in daily life and soft parts.

[0254] <Evaluation items>

[0255] (i) Speed ​​without secondary attachment effect;

[0256] (ii) Color persistence;

[0257] (iii) Smooth spreading.

[0258] <Absolute Evaluation Criteria>

[0259] (Rating): (Evaluation)

[0260] 5: Very good;

[0261] 4: Good;

[0262] 3: Neither;

[0263] 2: Poor;

[0266] (Judgment): (Evaluation)

[0267] AA: 4.5 or above;

[0268] A: 4.0 or above and below 4.5;

[0269] B: 3.5 or above and below 4.0;

[0270] C: 3.0 or above and below 3.5;

[0271] D: Less than 3.0 points.

[0272] (IV) Preventing separation within the process

[0273] Regarding prevention of separation within the process, as an evaluation method for separation immediately before filling, the stick-shaped cosmetics of the above-mentioned Examples and Comparative Examples were dissolved at 110°C, 50 g was filled into a cylindrical glass bottle with a diameter of 4 cm and a height of 8 cm, and the state after standing for 10 minutes while continuing to heat was observed, and judgment was made according to the following judgment criteria. These evaluations can verify the separation behavior of the oil and the color material within the process in the actual manufacturing process.

[0274] (Criteria for preventing separation within the process)

[0275] (Judgment): (Evaluation)

[0276] AA: No separation of oil / uneven color in the cosmetics;

[0277] A: Color unevenness / separation of the cosmetics was slightly observed, but it became uniform after shaking once;

[0278] B: Uneven color / separation of the cosmetic was observed, but it became uniform after shaking 2 times;

[0279] C: Separation was observed in the cosmetics, and it was not uniform even after shaking twice;

[0280] D: More separation occurs in the cosmetics.

[0281] (V) Mold release

[0282] Regarding the mold release property, each sample was pulled out to the end after being molded into a rod shape, and the appearance was visually evaluated according to the following criteria.

[0283] (Mold release criteria)

[0284] (Judgment): (Evaluation)

[0285] AA: Almost no peeling, cracking, breaking or defect is visible (the proportion in appearance is less than 2.5%).

[0286] A: Either peeling or defect is slightly visible (the proportion in appearance is less than 2.5-5%);

[0287] B: Peeling and defects are seen (the proportion in appearance is less than 2.5-5%);

[0288] C: Either peeling or defect is clearly visible. Although the impact on usability is small, it is unacceptable in terms of product appearance quality (the proportion of appearance is 5 to less than 10%)

[0289] D: Clear peeling, cracking, breaking, and chipping were observed, which were at a level that affected the usability (the proportion in appearance was 10% or more).

[0290] As can be seen from the results of Tables 1 to 5, the oily stick lipsticks of Examples 1 to 47 of the present invention are superior to the oily stick lipsticks of Comparative Examples 1 to 4 in terms of color durability, smooth spreading, speed without secondary adhesion effect, prevention of in-process separation, and demoldability.

[0291] On the other hand, in Comparative Example 1 without the component (A), color durability, smooth spreading, speed without secondary adhesion effect, and mold release properties were insufficient, and accordingly, a satisfactory product could not be obtained.

[0292] In Comparative Example 2 without component (B), color durability, smooth spreading, speed without secondary adhesion effect, and mold release properties were insufficient, and a satisfactory product could not be obtained.

[0293] In Comparative Example 3 without the component (C), the color durability, smooth spreading, speed without secondary adhesion effect, and mold release properties were insufficient, and a satisfactory product could not be obtained.

[0294] In Comparative Example 4 in which the component (E) was not present, the smooth spreading and the secondary adhesion effect were insufficient, and a satisfactory product could not be obtained.

[0295] As can be seen from the results in Table 6, the oily stick lipsticks of Examples 1 and 1-8 of the present invention are much superior to the oily stick lipsticks of Examples 1-2 to 1-7 and 1-9 to 1-12 in terms of color durability, smooth spreading, speed without secondary adhesion effect, prevention of separation in the process, and demolding properties. In particular, Example 1 is also preferred in terms of surface pattern.

[0296] In Example 1-2 of Manufacturing Method 2, since component (C) and component (D) are not brought into contact in advance, the color durability tends to decrease slightly, but it is very excellent in terms of smooth spreading, speed without secondary adhesion effect, prevention of separation in the process, and demolding properties.

[0297] In Example 1-3 of Manufacturing Method 3, since the addition temperature of component (B) is high, the fluidity of the substance generated in Step 1 is improved, the viscosity is reduced, and component (B) and component (D) are easily in contact, and it can be seen that the separation in the process tends to become slightly easier. However, it is very excellent in terms of color durability, smooth spreading, speed without secondary adhesion effect, and demolding properties.

[0298] In Example 1-4 of Manufacturing Method 4, since the addition temperature of component (B) is low, the viscosity of the substance generated in Step 1 is high, and component (B) is not easy to mix. Since it cannot be mixed evenly, it is easy to separate slightly during the process, and it can be seen that the smooth spreading tends to decrease slightly. However, it is very excellent in terms of color durability, speed without secondary adhesion effect, and demolding properties.

[0299] In Example 1-5 of Manufacturing Method 5, component (F) is added in step 1 instead of step 2. It can be seen that the smooth spreading tends to decrease slightly, but the color durability, speed without secondary adhesion effect, prevention of separation in the process, and demolding properties are very excellent.

[0300] In Example 1-6 of Manufacturing Method 6, the addition temperature of component (F) is lowered in step 2. However, due to the increase in the viscosity of the previous composition, component (F) is not easy to mix evenly, and there is a slight tendency to destroy the continuous wax crystal structure formed by components (A) to (E). However, it is very excellent in terms of color durability, speed without secondary adhesion effect, and prevention of separation within the process.

[0301] In Example 1-7 of Manufacturing Method 7, step 1 is changed to adding component (E) in step 2. Although the color durability effect is slightly reduced due to the contact between component (D) and component (E), it is very excellent in terms of smooth spreading, speed without secondary adhesion effect, prevention of separation in the process, and demolding properties.

[0302] In Example 1-9 of Manufacturing Method 9, the container was changed in Step 3, which affected the mold release and thus the smooth spreading, but was excellent in color durability, speed without secondary adhesion effect, and prevention of separation in the process.

[0303] In Examples 1-10 of Manufacturing Method 10, the dispersion equipment in Step 2 is different, and the color durability is slightly affected due to the influence of component (D), but it is very excellent in terms of smooth spreading, speed without secondary adhesion effect, prevention of separation in the process, and demolding properties.

[0304] In Examples 1-11 and 1-12 of the manufacturing method 11, in the step 2, instead of the step (2-1) of adding the component (B) later, the step (2-2) of pre-adding the component (B) and then dispersing was adopted. Therefore, the component (D) dispersed during the dispersion was discharged through the component (B), which tended to promote separation in the step, and sometimes also affected the mold release property. In addition, in Example 1-12 of the manufacturing method 12 in which the component (F) was added before the step 2, it was also seen that the color durability and smooth spreading tended to decrease, but the speed without the secondary adhesion effect was maintained.
