[Self-emulsification evaluation]
Test Method 0.1 g of the cleansing oil prepared above was gently dropped into 100 g of ion-exchanged water and allowed to stand overnight to prepare a 0.1% aq specimen.
Using a zeta potential / particle size measurement system (device name: ELSZ-1000ZS, manufactured by Otsuka Electronics Co., Ltd.), the volume average particle size of the prepared specimen was measured by a dynamic light scattering method.
The evaluation results are shown in Table 2.

Evaluation Example 1 had a smaller particle size than Comparative Examples 1 and 2.
In addition, it shows that self-emulsification property is so high that a particle size is small, and it is excellent in cleaning property.

[Evaluation of cleaning power]
Test Method (1) In a 2 cm × 2 cm frame of 3 cm × 6 cm white artificial leather, 0.004 g of lip color (FANCL Moisture Rouge P # 84 velvet red) was applied and dried for 30 minutes. This was used as a test sample.
(2) The color difference (L1) of the prepared test specimen was measured using a color difference meter (device name: CM-2600d, manufactured by Konica Minolta Co., Ltd.).
(3) A test sample was prepared by adding a predetermined amount of water to 100% by weight of the cleansing oil prepared in Example 1 or Comparative Examples 1 and 2.
(4) 0.1 ml of the test sample was dropped on the test specimen prepared in the above (1) and rubbed 10 times with an abrasion tester (device name: Mini-Martindale, James H. Heal & Co. Ltd.).
(5) Subsequently, 0.2 ml of ion-exchanged water was dropped on the test specimen and similarly rubbed 10 times with a wear tester.
(6) The specimen was washed thoroughly with water and dried.
(7) The color difference (L2) of the test specimen after drying was measured using a color difference meter.
(8) The makeup washing rate was calculated by the following formula.
Makeup washing rate (%) = 100 × (L1-L2) / (L1-L0)
However, L0 shows the color difference result of the white artificial leather before applying the lip color in FIG.

The makeup washing rates of Example 1 and Comparative Examples 1 and 2 were 98%, 97%, and 98%, respectively, when no water was added.
When water equivalent to 80% was added, Example 1 maintained a 96% make-up cleaning rate, but Comparative Example 1 was reduced to 51% and Comparative Example 2 to 87%.
When 100% equivalent amount of water was added, the makeup washing rate of Example 1 was 88%, but Comparative Example 1 was 52% and Comparative Example 2 was 69%.
Therefore, it was confirmed that the cleansing force of Example 1 is less likely to be reduced even if water is mixed, as compared with Comparative Example 1 that does not include the C component and D component and Comparative Example 2 that does not include the D component.

[Sensory evaluation test]
Cleansing oils of Example 2 and Comparative Examples 3 and 4 were prepared according to the formulation shown in Table 3 below.

Test method 31 professional panelists were allowed to use each sample for 3 days blindly, and the questionnaire was answered after use.
The evaluation items and answer options are shown below.
Evaluation item: Makeup removal answer choices: good, slightly good, neither, somewhat bad, bad

Evaluation item: Speed of flushing Answer options: good, slightly good, neither, somewhat bad, bad

Evaluation items: Touch options after washing: Feel nothing, others, cucumber, gritty, smooth

The evaluation results of makeup removal in Example 2 and Comparative Examples 3 and 4 are shown in FIG.
The total number of “good” and “slightly good” responses was summed, and the number of “slightly bad” and “bad” were totaled, and the ratio of the number of responses was shown in the graph. In Comparative Examples 3 and 4 that do not contain the D component, the percentages of makeup removal being poor or somewhat poor were 12.9% and 6.5%, respectively, while Example 2 was 0%.
Although the use method of a specialized panel has not been specified, it is normally assumed that water is mixed during cleansing, and Example 2 with high water solubilization power stably exhibits the effect of makeup removal. It was confirmed.

FIG. 3 shows the evaluation results of the flushing speed of Example 2 and Comparative Examples 3 and 4.
The total number of “good” and “slightly good” responses was summed, and the number of “slightly bad” and “bad” were totaled, and the ratio of the number of responses was shown in the graph.
In Example 2, compared with Comparative Examples 3 and 4 that do not contain the D component, the ratio of “good” and “somewhat good” was answered regarding the speed of washing, and “somewhat bad” and “bad” were answered. The ratio was small.
Example 2 contains D component, and since the emulsified particle size is small, it is presumed that the washing out was accelerated.

FIG. 4 shows the evaluation results of the touch after cleaning of Example 2 and Comparative Examples 3 and 4.
In Example 2, compared with Comparative Examples 3 and 4 that did not contain the D component, the ratio of responding “smooth” to the touch after washing was large.
Example 2 is considered to have a smooth feel because it contains a D component and the emulsified particle size is small, and the remaining after cleansing oil is small.

[Examination of surfactant]
Cleansing oils of Examples 3 to 9 were prepared according to the formulation shown in Table 4 below.
Cleansing oils of Comparative Examples 5 to 14 were prepared according to the formulation shown in Table 5 below.
Cleansing oils of Examples 10 to 15 and Comparative Examples 15 to 18 were prepared according to the formulations shown in Table 6 below.
The appearance of the obtained cleansing oil was observed and listed in Tables 4-6.
The solubilizing power of water and the emulsified particle size when water was added were measured by the following procedure, and the results are shown in Tables 4-6.

<Measurement of water solubilization power (test to evaluate "cleansing power when used with hands wet with water")>
In oily cleansing cosmetics, the oily component dissolves oily makeup stains, so it is important that the oil phase is continuous.
In this evaluation method, the amount of water solubilized transparently with respect to 100% by mass of the oil-based cleansing cosmetic was evaluated as the water solubilizing power.
Specifically, water was dropped while stirring each oil-based cleansing cosmetic, and the amount of water dropped until it became cloudy was measured.
It should be noted that the transparency can be maintained even when water is added, which means that an O / W emulsion composition is not formed even when water is mixed (reverse micelle phase, lamellar liquid crystal phase, bicontinuous microemulsion). Either).
The results are shown in Tables 4, 5, and 6 as water solubilizing power.

<Measurement of emulsion particle size when water is added to form an O / W emulsion composition ("Evaluation test without feeling of residual oil after washing with water")>
Water was added so that the amount was 60 times that of cleansing cosmetics to prepare an O / W type emulsion composition, and a particle size analyzer (apparatus name: Mastersizer 2000, manufactured by Malvern Instruments Ltd.) was contained in this composition. Was used to measure the particle size distribution by a laser diffraction method, and the volume average particle size was calculated as the emulsified particle size.
When the emulsified particle size is large, an oily feeling remains on the skin. If the emulsified particle size formed when water is added is 0.3 μm or less, it can be washed out quickly and clearly.
In addition, since the measurement lower limit of the particle size of the master sizer 2000 is 0.1 μm, the numerical value around 0.2 μm of the measured value of the volume average particle size increased. This is because the measurement is performed near the lower limit of measurement, and the actual particle size may be even lower. However, the master sizer 2000 was used because it was only necessary to determine whether the volume average particle size was 0.3 μm or less.
The results are shown in Tables 4, 5, and 6 as the emulsified particle size when water is added.
