3. The cleansing oil according to 1. or 2., wherein the D component is selected from the group consisting of PEG / PPG / polybutylene glycol-8 / 5/3 glycerol, glycerin, tripropylene glycol, and isopentyl glycol. , Polypropylene glycol (polypropanediol), PPG-14 polyglycerol-2 ether, PPG-10 methyl glucose, PPG-20 methyl glucose, PPG-9 diglycerol, DPG, diglycerol, polyglycerol-3, and polyglycerol-4 One or more of the groups formed.

Since the cleansing oil of the present invention exhibits high cleaning power even when water is mixed, it can be used with wet hands or in a bathroom or the like, and can be used very easily.

The cleansing oil of the present invention has a small emulsified particle size when suspended with a large amount of water, is excellent in rinseability, and does not easily leave a greasy feeling from the oil. Because the makeup removing oil of the present invention can sufficiently rinse the makeup, it is not easy to cause clogging of pores and rough skin, and can reduce the burden on the skin caused by friction and the like during makeup removal.

    [Example]    

[Evaluation of self-emulsifying properties and cleaning power]

The cleansing oils of Example 1 and Comparative Examples 1 and 2 were prepared according to the prescription of Table 1.

 Polyglyceryl-20 Hexanocaprylate: Eicosyl Glyceryl Hexanocaprylate Polyglycerol-20 Octanoisanoate: Eicosyl Glyceryl Octanoate Diisononanoate BG: 1,3-Butanediol Diisononanoic Acid Ester PEG / PPG / Polybutanediol-8 / 5/3 Glycerin: WILBRIDE S-753D made by Nippon Oil Co., Ltd.

[Self-emulsifying evaluation]

experiment method

In 100 g of ion-exchanged water, 0.1 g of the cleansing oil prepared above was gently added dropwise, and left to stand overnight to prepare a test subject of 0.1% aq.

The volume average particle diameter of the produced test body was measured by a dynamic light scattering method using a Zeta potential / particle size measurement system (device name: ELSZ-1000ZS, manufactured by Otsuka Electronics Co., Ltd.).

The evaluation results are shown in Table 2.

Evaluation

Example 1 has a smaller particle size than Comparative Examples 1 and 2.

In addition, it was shown that the smaller the particle size, the higher the self-emulsifying property and the better the cleaning property.

[Evaluation of cleaning power]

experiment method

(1) 0.004 g of lipstick (Fancl Moisture Rouge P # 84 Velvet Red) was applied and dried for 30 minutes in a range of 2 cm x 2 cm of a 3 cm x 6 cm white artificial leather. This was used as a test subject.

(2) A color difference meter (device name: CM-2600d, manufactured by Konica Minolta Co., Ltd.) was used to measure the color difference (L1) of the produced test subject.

(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) Add 0.1 ml of the test sample to the test subject prepared in (1) above, and rub it 10 times with a friction tester (device name: Mini-Martindale, James H. Heal & Co. Ltd.).

(5) Next, 0.2 ml of ion-exchanged water was dropped on the test subject, and rubbed with a friction tester 10 times in the same manner.

(6) The subject is thoroughly rinsed with water and allowed to dry.

(7) The color difference (L2) of the test subject after drying is measured using a color difference meter.

(8) The cosmetic washing rate was calculated by the following calculation formula.

Cosmetics cleaning rate (%) = 100 × (L1-L2) / (L1-L0)

Among them, L0 is the color difference of the white artificial leather before lipstick application

The results are shown in Figure 1.

The cosmetic washing rates of Example 1, Comparative Examples 1 and 2 were 98%, 97%, and 98% when water was not added.

When a considerable amount of water was added at 80%, Example 1 maintained a cosmetic cleaning rate of 96%, while Comparative Example 1 was 51% and Comparative Example 2 was 87%, and the cosmetic cleaning rate was decreased.

When a considerable amount of water was added, the cosmetic cleaning rate of Example 1 was 88%, while that of Comparative Example 1 was 52% and that of Comparative Example 2 was 69%, and the cosmetic cleaning rate was significantly reduced.

Therefore, it was confirmed that Example 1 is less likely to reduce the makeup removing power when compared with Comparative Example 1 not containing the C component and the D component and Comparative Example 2 not containing the D component.

[Sensory evaluation test]

The cleansing oils of Example 2, Comparative Examples 3, and 4 were prepared using the prescription in Table 3 below.

experiment method

Using blind testing, 31 professional evaluators used each sample for three days and answered the questionnaire after use.

The evaluation items and response options are shown below.

Evaluation item: makeup remover

Answer options: good, slightly better, not bad, not bad, slightly worse, worse

Evaluation item: speed of flushing

Answer options: good, slightly better, not bad, not bad, slightly worse, worse

Evaluation item: feel after washing

Answer options: nothing feels, other, clean, rough, smooth

The results of the makeup removal evaluation of Example 2 and Comparative Examples 3 and 4 are shown in FIG. 2.

The total number of “good” and “slightly good” responses is totaled, and the total number of “slightly poor” and “poor” responses are totaled, and the ratio of the number of responses is shown in the graph. In Comparative Examples 3 and 4 that did not contain the D component, the proportions of poor or slight makeup removal were 12.9% and 6.5%, respectively, and 0% in Example 2.

The use method of a professional evaluator is not particularly limited, but it is generally conceivable that water is mixed in when removing makeup, and it can be confirmed that Example 2 having a high solubilizing power of water can stably exhibit the effect of removing makeup.

The evaluation results of the washing speed in Example 2 and Comparative Examples 3 and 4 are shown in FIG. 3.

The total number of “good” and “slightly good” responses is totaled, and the total number of “slightly poor” and “poor” responses are totaled, and the ratio of the number of responses is shown in the graph.

In Example 2, compared with Comparative Examples 3 and 4 which did not include the D component, the ratios of "good" and "slightly good" were larger in terms of the washing speed, and the ratios of "slightly poor" and "bad" were smaller.

Since Example 2 contains the D component and the emulsified particle size becomes small, it is estimated that the rinse becomes faster.

The evaluation results of the feel after washing in Example 2, Comparative Examples 3, and 4 are shown in FIG. 4.

In Example 2, compared with Comparative Examples 3 and 4 which did not include the D component, the proportion of the answer "smooth" was larger in terms of the feeling after washing.

Since the Example contains the D component and the emulsified particle size becomes small, it is considered that there is little residue of the cleansing oil, and a smooth feel is obtained.

[Study of surfactant]

The cleansing oils of Examples 3 to 9 were prepared according to the prescription of Table 4 below.

The cleansing oils of Comparative Examples 5 to 14 were prepared according to the prescription of Table 5 below.

The cleansing oils of Examples 10 to 15 and Comparative Examples 15 to 18 were prepared according to the prescriptions in Table 6 below.

The appearance of the obtained cleansing oil was observed and described in Tables 4 to 6.

The solubilizing power of water and the emulsified particle size when water was added were measured in the following procedure, and the results are shown in Tables 4 to 6.

<Measurement of the solubilizing power of water (a test to evaluate the "makeup removing power when used with water-wet hands")>

In an oily makeup remover, since an oily component dissolves an oily cosmetic stain, continuous oily phase is particularly important.

In this evaluation method, the amount of water that can be transparently solubilized with respect to 100% by mass of the oily makeup remover is evaluated as the solubilizing power of water.

Specifically, water was added dropwise while stirring each oily makeup remover, and the amount of water added until it became cloudy was measured.

In addition, transparency can be maintained even when water is added, which means that it does not become an O / W type emulsified composition (any of a reverse microcellular phase, a layered liquid crystal phase, and a bicontinuous phase microemulsion) even if water is mixed.

The results are shown in Tables 4, 5, and 6 as the solubilizing power of water.

<Measurement of emulsified particle size when water is added to form O / W type emulsified composition ("no residual oil after washing" evaluation test)>

Water was added to the makeup remover so that it became 60 times the amount of the makeup remover, to prepare an O / W type emulsified composition, and a particle size analyzer (device name: Mastersizer-2000, manufactured by Malvern Instruments Ltd.) was used. The laser diffraction method was used to measure the particle size distribution in the composition, and the volume average particle diameter was calculated as the emulsified particle diameter.

When the emulsified particle size is large, the oil remaining on the skin is sexy. As long as the emulsified particle size formed when water is added is 0.3 μm or less, it can be rinsed quickly and lightly.

In addition, since the lower limit of the measurement of the particle size of the Mastersizer-2000 is 0.1 μm, the measurement value of the volume-average particle diameter becomes larger in the vicinity of 0.2 μm. This is because the measurement is performed near the lower limit of the measurement, so the actual particle size may be lower. However, as long as it can be judged whether the volume average particle diameter is 0.3 μm or less, Mastersizer-2000 is used.

The results are shown in Tables 4, 5, and 6 as the emulsified particle size when water was added.

As shown in Tables 4 to 6, the cleansing oils of Examples 3 to 15 of the present invention are transparent and uniform, the solubilizing power of water is 50% or more, and the emulsified particle size is 0.3 μm or less. That is, it is suggested that the cleansing oil of the present invention exhibits excellent rinseability even when mixed with water.

The water layer and the oil layer of the cleansing oils of Comparative Examples 5 to 10, 12, 14, 17, and 18 were separated, and were not suitable for use as cleansing oils. Moreover, the appearance of the cleansing oils of Comparative Examples 11, 13, 15, and 16 is transparent and uniform, but the poor solubilizing power of water or the emulsified particle size is as large as 2.4 μm or more, suggesting that the cleansing power is poor when mixed with water. Or poor flushability.

That is, it is suggested that the cleansing oil of the present invention exhibits excellent rinseability even when mixed with water.

The cleansing oils of Comparative Examples 19 to 38 had many separated water and oil layers. Even if the appearance was uniform, the solubilizing power of water was poor, or the emulsified particle size was as large as 7.0 μm or more, suggesting that the cleansing power was poor when mixed with water Or poor flushability.
