Add component (A) or component (A ′), component (D), component (H), component (G) to component (B), stir and homogenize, then add component (C) to component (F) And component (I) was added and stirred until uniform. The obtained two liquids were mixed, the component (E) or the component (E ′) was added, and stirred and mixed to obtain the cosmetics of each example.

(Evaluation method)
(Storage stability of cosmetics at low temperatures)
90 mL of the cosmetic material obtained in each example was filled in a 100 mL transparent glass bottle. The appearance of each cosmetic after being stored in a thermostatic bath at −5 ° C. for one month was visually observed and evaluated according to the following criteria, and those with an evaluation result of “◎” or “◯” were accepted.

A: There is no precipitation of crystals or solids O: Little precipitation of crystals or solids Δ: Some precipitation of crystals or solids x: Many precipitations of crystals or solids

(Usage feeling: smooth feeling)
A sensory evaluation was performed by three specialized panels, and the smooth feeling when the cosmetic was applied to the skin was evaluated based on the following evaluation criteria. Next, the evaluation points given by each person were totaled and evaluated based on the following evaluation criteria. The higher the numerical value (total score), the better the effect.

◎: 14 points or more ○: 12 points or more Δ: Greater than 9 points ×: 9 points or less

(Usage: Cool feeling immediately after)
A sensory evaluation was performed by three specialist panels, and the refreshing feeling immediately after the cosmetic was applied to the skin was evaluated based on the following evaluation criteria. Next, the evaluation points given by each person were totaled and evaluated based on the following evaluation criteria. The higher the numerical value (total score), the better the effect.
[Evaluation criteria]
5 points: Very refreshing 4 points: Cool 3 points: Normal 2 points: Inferior 1 point: Very inferior [Evaluation criteria]
◎: 14 points or more ○: 12 points or more Δ: Greater than 9 points ×: 9 points or less

(Usage feeling: no irritation)
Three specialist panels applied 30-50 mg of the cosmetic material obtained in each case to the skin within 8 × 2 cm inside the forearm, and immediately after application, each person scored according to the following evaluation criteria. Next, the average value of evaluation points given by each person was calculated, and the absence of irritation to the skin was evaluated according to the following criteria.
[Evaluation criteria]
0: No irritation or redness is observed.
1: Although there is no irritation, only a slight redness is observed.
2: Slight irritation or redness is observed.
3: A feeling of irritation and redness are observed.
〔Evaluation criteria〕
◎: The average value of the subjects is less than 1 ○: The average value of the subjects is 1 or more and less than 1.5 Δ: The average value of the subjects is 1.5 or more and less than 2 ×: The average value of the subjects is 2 or more

From Table 1 and Table 2, the cosmetics described in each example contain components (A) to (F), and the contents of components (B), (C), and (E) are in a specific range. Therefore, the storage stability of the cosmetic at a low temperature was excellent as compared with the cosmetic of each comparative example. In addition, the cosmetics described in each Example were excellent in the balance of the effects of a smooth feeling when the cosmetic was applied to the skin, a refreshing feeling immediately after application, and no irritation.
Also, the cosmetic material of each example can be impregnated into a sheet-like base material and used as a sheet-like cosmetic material.
