The following analysis is given in light of this disclosure.

Addition of a non-volatile hydrocarbon oil having a high kinematic viscosity, such as the oil-based solid cosmetic described in Patent Document 1, makes it possible to impart luster and moistness to the skin to which the cosmetic is applied. On the other hand, if a large amount of such non-volatile hydrocarbon oil is added, the cosmetic spreads poorly during application, and the user feels stickiness due to the non-volatile hydrocarbon oil after application. Therefore, in order to improve the spreadability of the cosmetic and reduce the stickiness, it is conceivable to mix silicone oil with the non-volatile hydrocarbon oil as in the lip cosmetic described in Patent Document 2. However, in general, high kinematic viscosity non-volatile hydrocarbon oils and silicone oils have low compatibility. Therefore, simply mixing a non-volatile hydrocarbon oil with a high kinematic viscosity and a silicone oil does not provide the same level of stability as the lip cosmetic described in Patent Document 2, resulting in component separation and the like. . Therefore, in order to enhance the feeling of use during and after application, it is necessary to ascertain a region in which non-volatile hydrocarbon oil with high kinematic viscosity and silicone oil can coexist stably.

Therefore, there is a demand for a highly stable cosmetic composition in which a large amount of non-volatile hydrocarbon oil with high kinematic viscosity is blended while the drawbacks caused by the non-volatile hydrocarbon oil with high kinematic viscosity are improved.

According to the first aspect of the present disclosure, the oily solid cosmetic comprises (A) 7% by mass to 62% by mass of nonvolatile hydrocarbon oil having a kinematic viscosity of 3,000 mm ² /s to 500,000 mm ² /s and (B) a volatile oil, (C) 1% by mass or more of a non-volatile silicone oil, and (D) 4% to 22% by mass of a wax having a melting point of 80° C. or higher. Component (B) is 0.2 parts by mass or more per 1 part by mass of Component (A). The total amount of silicone oil contained in components (B) and (C) is 0.06 to 1.3 parts by mass per 1 part by mass of component (A).

According to the oil-based solid cosmetic composition of the present disclosure, it is possible to give a glossy and moist feeling to the skin to which it is applied. The oil-based solid cosmetic composition of the present disclosure can be applied to the skin smoothly and with a feeling of fit to the skin even when a non-volatile hydrocarbon oil with a high kinematic viscosity is blended. The oil-based solid cosmetic composition of the present disclosure suppresses stickiness after application even when a non-volatile hydrocarbon oil with high kinematic viscosity is blended. The oil-based cosmetic of the present disclosure has high stability even when a non-volatile hydrocarbon oil and silicone oil with high kinematic viscosity are blended.

The other was allowed to stand under conditions of 40° C. for one month. No oil exudation was observed in the appearance of the product left standing at room temperature. Therefore, the appearance of the product left at rest at 40° C. and the product left at room temperature were compared, and the stability of the composition was evaluated according to the following criteria:
A: There was no difference in appearance between the product left at 40°C and the product left at room temperature;
B: The product left standing at 40°C showed oil oozing out, but when the product left standing at 40°C was left at room temperature, there was no difference from the product standing at room temperature (the exuded oil was the cosmetic returned inside);
C: The product left standing at 40°C showed oil oozing, and the oil oozing did not disappear even when the product left standing at 40°C was left at room temperature;
D: It was difficult to maintain the shape of the product left at 40°C.

B: average value of 3.5 points or more and less than 4.5 points;
C: average value of 2.5 points or more and less than 3.5 points;
D: Average value less than 2.5 points.

The oily solid cosmetic of Test Example 1 using hydrogenated polyisobutene with a kinematic viscosity of 15,000 mm ² /s to 20,000 mm ² /s was good in all test items. On the other hand, the oil-based solid cosmetic of Test Example 2, which used hydrogenated polyisobutene with a kinematic viscosity of 20 mm ² /s, gave a poor evaluation of fit (holding) during application. In addition, the evaluation of resistance to wrinkling was also low. Furthermore, the evaluation of moist feeling and gloss was also low. From this, it is considered that the kinematic viscosity of component (A) is preferably 3,000 mm ² /s or more.

In Test Example 3 in which the content of hydrogenated polyisobutene was lower than in Test Example 1, good evaluation was obtained, but the evaluation was lower than in Test Example 1 overall. In Test Example 4, in which the content of hydrogenated polyisobutene was lower than in Test Example 3, the evaluation of moist feeling and gloss was low. In addition, since the amount of silicone oil was relatively large with respect to the amount of hydrogenated polyisobutene, the fit feeling and the resistance to wrinkling were also low. From this, the component (A) is preferably at least 7% by mass, more preferably at least 10% by mass, more preferably at least 15% by mass, and even more preferably at least 20% by mass. I get it.

In Test Example 5 in which the content of hydrogenated polyisobutene was higher than in Test Example 1, good evaluation was obtained, but the evaluation was lower than in Test Example 1 overall. In Test Example 6, in which the content of hydrogenated polyisobutene was higher than in Test Example 5, stickiness occurred, and the fitting feeling and resistance to wrinkling were evaluated as low. From this, it is considered that the content of component (A) is more preferably 62% by mass or less, and more preferably 55% by mass or less.

In Test Example 7, hydrocarbon oil was used instead of silicone oil as (B) volatile oil. The cosmetic of Test Example 7 was able to obtain an evaluation equivalent to that of Test Example 1. Similar evaluations were made in Test Examples 11 and 12, which will be described later. From this, it was found that component (B) is not limited to volatile silicone oils, and that other volatile oils can also be applied. Comparing Test Examples 1 and 7, and comparing Test Examples 11 and 12, Test Examples 1 and 11 exhibited better spreadability of the cosmetic. From this, it is considered that component (B) preferably contains volatile silicone oil, and volatile silicone oil is more preferable than hydrocarbon oil.

In Test Example 8, the amount of (B) volatile silicone oil was less than in Test Example 1. As a result, the stickiness became stronger, and the feel during application worsened. Therefore, it is considered preferable that the amount of component (B) is 0.2 parts by mass or more with respect to 1 part by mass of component (A). In addition, it is believed that component (B) can be 5% by mass or more.

In Test Example 9, the ratio of the amount of component (B) to component (A) ((B)/(A)) and the ratio of the total amount of silicone oil to component (A) ({(B1) + (C)}/ (A)) was made larger than in Test Example 1. As a result, the compatibility between the component (A) and the silicone oil was lowered, and the high-temperature stability of the cosmetic was also lowered. In Test Example 10, (C) the nonvolatile silicone oil was increased more than in Test Example 1 so that the total amount of silicone oil (the total amount of volatile and nonvolatile) was the same as in Test Example 9. That is, {(B1)+(C)}/(A) was made the same as in Test Example 9, and (B)/(A) was made the same as in Test Example 1. As a result, similar to Test Example 9, the compatibility between the component (A) and the silicone oil was lowered, and the high-temperature stability of the cosmetic was also lowered. On the other hand, in Test Example 11, the non-volatile silicone oil in Test Example 10 was replaced with ester oil to reduce the total amount of silicone oil. That is, {(B1)+(C)}/(A) was lowered while keeping (B)/(A) the same as in Test Examples 1 and 10. As a result, the total amount of silicone oil relative to component (A) was less than in Test Examples 9 and 10. As a result, the evaluation of the cosmetic stability was good as in Test Example 1. From this, it is considered that the low stability evaluation in Test Examples 9 and 10 is due to the total amount of silicone oil being larger than that of component (A). It is considered preferable that the total amount of silicone oil is 1.3 parts by mass or less per 1 part by mass of component (A).

In Test Example 11, which did not contain component (C), it was evaluated that stickiness occurred. Similar evaluations were also made in Test Example 12 in which the component (B) in Test Example 11 was a hydrocarbon oil. From this, it is considered that the component (C) contributes to the reduction of stickiness.

Good evaluation was obtained in Test Example 13 in which the component (C) was 2% by mass. On the other hand, in Test Example 14 in which the component (C) was 0.5% by mass, it was evaluated that the stickiness was increased. From this, it is considered that the component (C) is preferably 1% by mass or more, and more preferably 2% by mass or more.

In Test Examples 15 and 16, a hydrocarbon oil was used as component (B) to reduce the total amount of silicone oil. A good evaluation was obtained in Test Example 15 in which the total amount of silicone oil was 0.12 parts by mass per 1 part by mass of component (A). On the other hand, in Test Example 16 in which the total amount of silicone oil was 0.04 parts by mass with respect to 1 part by mass of component (A), elongation during application decreased in the same manner as in Test Example 12 containing no silicone oil. have done. From this, it is considered that the total amount of silicone oil is preferably 0.06 parts by mass or more, more preferably 0.1 parts by mass or more, per 1 part by mass of component (A).

In Test Examples 17 to 19, a wax having a melting point of 60 to 65°C was used instead of a wax having a melting point of 80°C or higher. As a result, the high-temperature stability of the cosmetic has deteriorated. Also, in Test Example 20 in which 3% by mass of wax having a melting point of 88 to 91° C. was added, the evaluation was the same as in Test Example 18 in which the total amount of component (D) was the same. On the other hand, in Test Example 21 in which 5% by mass of wax having a melting point of 88 to 91° C. was added, high high-temperature stability could be obtained. Waxes with a melting point of 80° C. or higher are considered to contribute to the high-temperature stability of cosmetics. Therefore, it is considered preferable that the component (D) is a wax having a melting point of 80° C. or higher. As shown in Test Example 21, good evaluation can be obtained even if the cosmetic contains wax having a melting point of less than 80°C.

Good evaluation was obtained in Test Example 22 in which 5% by mass of component (D) was added. On the other hand, in Test Example 23 in which 3% by mass of component (D) was added, the high-temperature stability was lowered. From this, it is considered that the component (D) is preferably 4% by mass or more, and more preferably 5% by mass or more.

Good evaluation was obtained in Test Example 24 in which 20% by mass of component (D) was added. On the other hand, in Test Example 25 in which 25% by mass of the component (D) was added, the elongation during application decreased. Also referring to Test Examples 18 to 20, it is believed that the amount of wax affects the elongation of the cosmetic. Based on this, the content of component (D) is preferably 22% by mass or less, and more preferably 20% by mass or less.

In Test Example 26, mica was excluded from the composition of Test Example 1. As a result, a good evaluation was obtained, but the feeling of fit, non-stickiness, and resistance to wrinkling were lower than in Test Example 1. From this, it is considered preferable that the cosmetic contains 1% by mass or more of mica.
