Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to an oil-in-water cosmetic material. BACKGROUND
[0002] In order to protect the human body from ultraviolet rays in various situations in daily life, attempts have been made to incorporate ultraviolet absorbers in cosmetic materials. There are many challenges in achieving cosmetic materials that are excellent in terms of ultraviolet defense effect and use feeling.
[0003] Attempts have been made to enable the ultraviolet defense effect and good use feeling by making the total amount and the incorporation ratio of the higher alcohol and the surfactant be within a specific range (Patent Document 1), but if the higher alcohol is too much, the spread and stickiness of the application are generated, and thus the effect is insufficient.

[0117] As shown in Table 3, the composition containing the benzotriazole type ultraviolet absorber and the silicone wax is excellent in the quick-drying property, the skin affinity, and the emulsified state, as compared with the composition not containing the silicone wax or containing a synthetic wax instead of the silicone wax as a non-silicone. The composition of the present application is high in the quick-drying property and the skin affinity, and therefore, the composition is less likely to adhere to clothes or skin from immediately after application, and a comfortable feeling of use can be given to the user.
[0118] [Experiment Example 4]
[0119] An oil-in-water type composition having the composition shown in Table 4 below was prepared according to a conventional method, and the skin affinity, the rubbing resistance, and the emulsified state were evaluated. The evaluation standards for the skin affinity and the emulsified state were the same as those of Experiment Example 3.
[0120] (Evaluation standard for rubbing resistance)
[0121] ◎: no change even when the applied part was rubbed back and forth 10 times with a finger after 2 minutes from the application to the skin.
[0122] O: After 2 minutes of application to the skin, no change was observed when the applied portion was rubbed back and forth 10 times with a finger.
[0123] Δ: After 2 minutes of application to the skin, lumps of the composition in the form of white stripes were observed when the applied portion was rubbed back and forth 10 times with a finger.
[0124] X: After 2 minutes of application to the skin, lumps of the composition in the form of large white stripes were observed when the applied portion was rubbed back and forth 10 times with a finger.

[0130] As shown in Table 4, the composition containing a benzotriazole-type ultraviolet absorber and silica having an average particle diameter of 2 μm was excellent in skin affinity, rubbing resistance, and emulsion state, as compared with the composition containing silica having an average particle diameter of 12 nm or the composition containing water at 45 mass%. The composition containing silica having an average particle diameter of 12 nm was very poor in emulsion state, and other evaluations could not be performed. The composition of the present application was high in skin affinity and rubbing resistance, and therefore, the composition was less likely to adhere to clothes or the skin from immediately after application, and a comfortable feeling of use could be given to the user, and these effects lasted for a long time.
[0131] [TEST EXAMPLE 5]
[0132] An oil-in-water composition having the composition shown in Table 5 below was prepared according to a conventional method, and the quick-drying property, skin affinity, secondary adhesion, and emulsion state were evaluated. The evaluation criteria for the quick-drying property were the same as in Test Example 1. The evaluation criteria for the skin affinity and emulsion state were the same as in Test Example 3.
[0133] (Evaluation Criteria for Secondary Adhesion)
[0134] One gram of the composition was applied to the central portion of the wrist to the elbow, and left to stand for 10 seconds. Fifty pieces of paper having a square shape with one side of 1 cm were dropped from a height of 10 cm from the applied portion. After the applied portion was temporarily pressed with a palm, the number of pieces of paper remaining on the applied portion was measured. Next, the applied portion was moved back and forth in the horizontal direction by a distance of 15 cm for 10 times with the applied portion kept facing upward, and the number of pieces of paper remaining on the applied portion was measured.
[0135] O: All of the paper sheets were peeled off from the application part when the arm was moved.
[0136] O: More than 90% of the paper sheets were peeled off from the application part when the arm was moved.
[0137] Δ: More than 90% of the paper sheets were peeled off from the application part when the arm was moved.
[0138] X: More than 90% of the paper sheets were peeled off from the application part when the arm was moved, and traces of the composition penetrating were observed in the attached paper sheets.
