Description

  The present invention relates to a composition for external use.

  Ultraviolet rays include ultraviolet A waves (UV-A, 315 to 400 nm), ultraviolet B waves (UV-B, 280 to 315 nm), and others. Of these, UV-A is less likely to cause sunburn, but recent studies have shown that it is greatly involved in the formation of spots and wrinkles. That is, UV-A has a long wavelength and reaches deep into the skin, and has an effect of, for example, denaturing collagen.

  UV-B has a short wavelength and is blocked by the ozone layer and clouds as compared with UV-A, and the amount reaching the ground is a small amount of about 10% of the total amount of ultraviolet rays. However, UV-B is strong in energy and damages cells on the skin surface or causes inflammation, which may cause skin cancer and spots.

  Thus, as the influence of ultraviolet rays on the skin becomes clear, there is an increasing demand for external compositions having a high ultraviolet blocking effect, and various external compositions have been proposed (Patent Document 1).

  External compositions having the compositions shown in Tables 1 to 4 were prepared according to a conventional method. Specifically, each of the oil phase component and the water phase component was weighed and dissolved by heating as necessary. Thereafter, in the case of the O / W type composition, the oil phase was added to the aqueous phase, and the mixture was stirred and prepared with a homomixer to prepare uniform O / W type compositions (Tables 1 and 3). In the case of the W / O type composition, the aqueous phase was added to the oil phase and stirred to prepare a uniform W / O type composition (Tables 2 and 4).

(Test Example 1) Ultraviolet ray protection effect test Each composition for external use described in Tables 1 to 4 was uniformly applied to a plate made of polymethyl methacrylate (PMMA) so as to be 1.3 mg / cm ² , and was in a dark place. And allowed to dry for 15 minutes, and then the ultraviolet absorption spectrum was measured using an ultraviolet-visible spectrophotometer (UV-2450: manufactured by Shimadzu Corporation). The increase rate (enhancement effect) of the ultraviolet absorption spectrum was calculated by comparing the area under the absorbance curve (AUC) at 290 to 400 nm with that of the blank formulation (prescription not including the component (A)). The calculation formula is as follows:
[Formula 1]
Increase rate of ultraviolet absorption spectrum = [(each AUC in Examples) / (each AUC in Comparative Examples)] × 100 (%)
In addition, the ultraviolet absorption spectrum measured five different points in the same PMMA board, and took those average values. The blank formulations in Table 1, Table 2, Table 3 or Table 4 are the formulations of Comparative Example 1, Comparative Example 3, Comparative Example 5 or Comparative Example 6, respectively. In Comparative Example 2 or Comparative Example 4, the rate of increase in the ultraviolet absorption spectrum of the formulation of Comparative Example 2 or Comparative Example 4 relative to Comparative Example 1 or Comparative Example 3 which is the respective blank formulation was determined by Equation 1.

  The results of Test Example 1 with the formulations shown in Table 1 are also shown in Table 1. Compared to Comparative Example 1 with only component (B) or Comparative Example 2 with only component (A) and component (B), Example 1 or Example 2 containing components (A) to (C) is UV-absorbing It was confirmed that the spectrum increased.

  The results of Test Example 1 with the formulation in Table 2 are also shown in Table 2. Compared to Comparative Example 3 with only the component (B) or Comparative Example 4 with only the component (A) and component (B), Example 3 or Example 4 containing the components (A) to (C) is UV-absorbing. It was confirmed that the spectrum increased.

  The results of Test Example 1 with the formulations shown in Table 3 are also shown in Table 3. It was confirmed that the ultraviolet absorption spectrum increased in Example 5 containing the components (A) to (C) as compared with Comparative Example 5 containing only the component (B).

  The results of Test Example 1 with the formulation in Table 4 are also shown in Table 4. Compared to Comparative Example 6 containing only the component (B), it was confirmed that Example 6 containing the components (A) to (C) increased in the ultraviolet absorption spectrum.

(Test Example 2) Residual test after water treatment For the composition for external use shown in Table 1 or Table 2, after measuring the ultraviolet absorption spectrum in Test Example 1, water treatment was performed, and the ultraviolet ray was again treated in the same manner. The absorption spectrum was measured, the area under the absorbance curve (AUC) at 290 to 400 nm before and after water treatment was compared, and the residual ratio was calculated. The calculation formula is as shown in the following formula 2.
[Formula 2]
Residual rate after water treatment = [(AUC after water treatment) / (AUC before water treatment)] × 100 (%)
In this test example, the water treatment means that a PMMA plate coated with the composition is attached to one end of a stirring blade of a water bath and immersed in a water bath (tap water) at 20 to 25 ° C. for 5 minutes. The PMMA plate is then slowly removed and left in the dark for 30 minutes to dry.
Moreover, the ultraviolet absorption spectrum measured five different points in the same PMMA board, and took those average values.

  This test corresponds to the harsh conditions of actual use when tap water, rain, pool water, etc. contact the external composition after applying the external composition of the present invention. It turns out that the composition of an example is excellent in water resistance and the ultraviolet-ray protective effect durability.

  Table 5 shows the results of Test Example 2 with the formulations shown in Table 1. Compared to Comparative Example 1 containing only the component (B), Example 1 containing the components (A) to (C) had a good residual rate after water treatment.

  Table 6 shows the results of Test Example 2 with the formulations shown in Table 2. Compared with the comparative example 3 only of (B) component or the comparative example 4 of only the (A) component and (B) component, Example 3 or Example 4 containing the (A) component-(C) component is water treatment. The remaining rate was good.

(Test Example 3) Secondary Adhesion Evaluation Test Each external composition of Example 1 in Table 1 and Example 3 in Table ² was uniformly applied on a PMMA plate with a sample of 2 mg / cm ² and dried. It was. As a separate control, the compositions for external use of Comparative Example 1 in Table 1 and Comparative Example 3 in Table 2 were similarly uniformly coated on a PMMA plate and dried. After drying the sample, the ultraviolet absorption spectrum of each PMMA plate was measured with an ultraviolet-visible spectrophotometer (UV-2450; manufactured by Shimadzu Corporation), and the area under the absorbance curve (AUC) at 290 to 400 nm was determined. Thereafter, the coated surface of the PMMA plate was placed on the tissue paper, and a load of 500 g was attached to the tissue paper over 10 minutes from the top of the PMMA plate. Then, the ultraviolet absorption spectrum was measured again, and 290 to 400 nm. AUC was obtained, and the difference in AUC before and after the adhesion was compared to calculate the residual ratio of the ultraviolet absorptivity. The smaller the difference, the lower the secondary adhesion was evaluated. The calculation formula is as shown in Formula 3.

Residual rate of ultraviolet absorbing ability = [(each AUC after adhesion) / (each AUC before adhesion)] × 100 (%)
In addition, the ultraviolet absorption spectrum measured five different points in the same PMMA board, and took those average values.

  The results of Example 1 and Comparative Example 1 in Table 1 are shown in Table 7. Table 8 shows the results of Example 3 and Comparative Example 3 in Table 2. As a result, it was confirmed that Example 1 and Example 3 including the components (A) to (C) of the present invention hardly adhere to secondary adhesion.

  In the composition for external use of the present invention, the preparation stays on the skin even after application, and the ultraviolet protection effect can be maintained.

  O / W type external compositions having the compositions shown in Table 9 were prepared according to a conventional method. Specifically, each of the oil phase component and the water phase component was weighed and dissolved by heating as necessary. Thereafter, the oil phase was added to the aqueous phase, and the mixture was stirred and prepared with a homomixer to prepare a uniform O / W type composition. Moreover, if necessary, a neutralizing agent was added after stirring to prepare a uniform composition.

(Test Example 4) Stripping evaluation test About 2 mg of each composition for external use described in Table 9 was applied onto an artificial leather, uniformly applied in a circular shape having a diameter of 10 mm, and allowed to stand at room temperature for 2 minutes. . The edge of the stainless steel spatula (length 8 mm, total weight of the spatula 9.4 g) was applied to the outer edge of the composition circle, and the spatula was moved 10 mm from there to the outer edge on the opposite side of the circle. The spatula moved 45 degrees from the artificial leather so that the center of the edge of the spatula passed through the center point of the circle. Further, in order to make the force for moving the spatula constant, the other end of the spatula was moved while being lightly held by two fingers.

Next, the weight of the composition adhering to the spatula was measured. Each external composition was measured twice to obtain an average value. The peeling improvement rate of each composition for external use with respect to Comparative Example 7 was calculated. The calculation formula is as the following formula 4. The results are also shown in Table 9.
[Formula 4]
Stripping improvement rate (%) = {1− (average value of weight of example / average value of weight of comparative example 7)} × 100

  As shown in Table 9, in Examples 7 to 14 including the (A) component to the (C) component, the exfoliation property of the external composition was favorably improved as compared with the comparative example not including the (C) component. If it is the composition for external use of this invention, even if it is the environment rubbed with clothes, hair, etc. after applying to skin, it remains on the skin well and the effect of the components contained in the composition for external use of this invention is maintained. Can be demonstrated.

(Test Example 5) Application property test (1-1)
About 8 mg of each composition for external use described in Table 9 was taken on artificial leather and uniformly applied so as to form a circle having a diameter of 10 mm. Immediately after that, place the finger so that the center of the belly of the finger is at the center of the circle of the composition, and move the finger once in a straight line to the right to apply the composition onto the artificial leather. I did it. The distance from the outer edge on the left side of the circle to the end point where the composition was spread was measured. The finger movement speed was kept constant.

Each external composition was measured twice, and the average value was taken as the extended distance. The expansion improvement rate of each composition for external use with respect to Comparative Example 7 was calculated. The calculation formula is as shown in Formula 5 below. The results are also shown in Table 9.
[Formula 5]
Prolongation Improvement Rate (%) = {(Expansion Distance of Example / Expansion Distance of Comparative Example 7) −1} × 100

  As shown in Table 9, in Examples 7 to 14 including the component (A) to the component (C), compared with the comparative example not including the component (C), “Nobi” when the composition for external use was applied. It was good. If it is the composition for external use of this invention, it is easy to spread even if the application area to skin is wide.

(Test Example 6) Application property test (1-2)
Artificial leather was affixed to cover the bottom of the cylinder (diameter 3.8 cm), and about 8 mg of each external composition (Table 9) was placed on the artificial leather. The face to which the artificial leather of the cylinder was affixed was faced down so that it could not be seen by the subject, and the external composition was spread over the entire bottom of the cylinder using the index finger. The time until it was felt that the paint was evenly spread was measured. To spread evenly means that the composition for external use spreads over the entire artificial leather on the bottom surface of the cylinder, or that the fingertip feels that it has spread to the same thickness.

Each external composition was measured twice, and the average value was defined as a uniform time. The improvement rate of the uniformity of each external composition relative to Comparative Example 7 was calculated. The calculation formula is as the following formula 6. The results are also shown in Table 9. In addition, when the test was similarly performed about Example 2 and the comparative example 2, and the improvement rate (%) of the uniformity of Example 2 with respect to the comparative example 2 was calculated | required, it was 20%.
[Formula 6]
Uniformity improvement rate (%) = {1− (time for uniforming of example / time for uniforming of comparative example 7)} × 100

  As shown in Table 9, in Examples 7 to 14 including the component (A) to the component (C), compared to the comparative example not including the component (C), “uniformity” when applying the composition for external use. Was good. Although it is not limited, the composition for external use of the present invention is easily spread evenly even when it is not applied to the skin while being visually observed.

(Test Example 7) Application property test (1-3)
Artificial leather was affixed to cover the bottom of the cylinder (diameter 3.8 cm), and about 8 mg of each external composition (Table 9) was placed on the artificial leather. The surface on which the artificial leather of the cylinder was affixed was faced down so that it could not be seen by the subject, and the index composition was used to spread the external composition evenly over the entire bottom surface of the cylinder. After feeling that it was evenly spread, we continued to spread and measured the time it took to feel that the whole surface with artificial leather attached was dry. The fact that the entire surface to which the artificial leather is attached is dry means that the surface returns to the feeling of rubbing the artificial leather before the test and does not feel sticky.

Each external composition was measured twice, and the average value was defined as the quick drying time. The improvement rate of the quick drying property of each composition for external use with respect to Comparative Example 7 was calculated. The calculation formula is as the following formula 7. The results are also shown in Table 9. In addition, when the test was similarly performed about Example 2 and Comparative Example 2, and the improvement rate (%) of quick-drying property of Example 2 with respect to Comparative Example 2 was calculated | required, it was 20%. Moreover, when the test was similarly performed about Example 4 and Comparative Example 4, and the improvement rate (%) of quick-drying property of Example 4 with respect to Comparative Example 4 was calculated | required, it was 51%.
[Formula 7]
Improvement rate of quick drying (%) = {1− (fast drying time of example / fast drying time of comparative example 7)} × 100

  As shown in Table 9, in Examples 7 to 14 including the component (A) to the component (C), compared to the comparative example not including the component (C), “fast drying” when applying the composition for external use. Was good. Although it is not limited, if it is the composition for external use of this invention, even if it is a case where it does not apply | coat to skin visually, it will become possible to apply | coat to skin rapidly.

(Test Example 8) Application test (2)
About 8 mg of each composition for external use described in Table 10 was applied to the arm by three subjects and scored for the feeling of application (spreading, uniformity, quick drying). In order of evaluation, Example 2 was performed after Comparative Example 2, and Example 4 was performed after Comparative Example 4. The evaluation score was 0 points when feeling that Example 2 was bad compared to Comparative Example 2, 1 point when feeling that Example 2 was the same, and 2 points when feeling that Example 2 was good. Similarly, in Comparative Example 4 and Example 4, Example 4 was evaluated as compared with Comparative Example 4. The judgment criteria for the coating feeling were as follows.

[Evaluation criteria]
Nobi: Feeling less sensitive to the finger sensation of applying the external composition and feeling that the same amount of the external composition can be applied over a wider range. Uniformity: The applied external composition has the same thickness on the skin. Feeling that it can be applied evenly Quick drying: Feeling that the composition for external use itself at the time of application almost disappears and feels familiar with the skin. The average evaluation score of the subjects is also shown in Table 10.

  As shown in Table 10, in Example 2 or Example 4 containing the components (A) to (C) as compared with Comparative Example 2 or 4 that does not contain the component (C), the composition for external use was applied. “Nobi”, “uniformity” and “quick drying” were good. If it is the composition for external use of this invention, when apply | coating to skin, it will be easy to spread uniformly in a short time, and it will become possible to exhibit the effect of the component contained in the composition for external use of this invention uniformly.
