The formula of the skin cleansing oil of the present invention in the examples 6 to 9 is shown in table 2, and the preparation method is the same as that of the examples 1 to 5.

Comparative examples 3 to 7

Comparative examples 3 to 7 are skin cleansing oils, the formulations of which are shown in Table 2, and the preparation methods are the same as in examples 1 to 5.

TABLE 2 recipe table (parts by weight)

Performance testing

(1) Stability of

The stability of examples 1 to 9 and comparative examples 1 to 7 was tested, 50g of each of examples 1 to 9 and comparative examples 1 to 7 was weighed, stored at 5 ℃, and whether the samples were layered after standing for 24 hours, 48 hours, 1 week, and 2 weeks was observed, and the results are shown in table 3.

As can be seen from Table 3, the cleansing oil prepared by the formula of the comparative example 1 does not contain PEG-8 caprylic/capric glycerides, and can be layered after being stored at 5 ℃ for 48 hours, so that the stability is poor; in the comparative example 2, the ratio of the oil phase to the water phase exceeds 75-85: 15-25, and the prepared facial cleansing oil is very easy to stratify and is very unstable.

(2) Moisture retention

The test principle is as follows: the moisture test method uses the CORNEOMETER-capacitance method, and because water has high permittivity, the hydration degree of the skin surface layer, namely the water content of the stratum corneum, can be measured by the permittivity. The Corneometer CM825 skin moisture tester (Courage & Khazaka, germany) is based on this principle and reflects the moisture content in the skin surface layer by measuring the capacitance reading of the probe after contact with the skin, the higher the moisture content of the surface layer, the higher its capacitance and vice versa. The result is expressed by a set humidity Measurement Value (MMV). The MMV is a value of 0 to 150. The capacitance measuring method is superior to other methods in that the test result is practically not affected by polarization effect and ionic conductivity since the skin to be tested is not in unnatural contact with the test probe and almost no current flows through the skin to be tested. The instrument probe and the water in the skin have no inertia in the process of establishing balance, and can realize quick measurement, thereby eliminating the influence of active skin on the measurement result.

And (3) testing conditions are as follows: the test was carried out at 20 ℃ and 50% relative humidity.

The test method comprises the following steps: the moisture test probe is vertically pressed on the surface of the skin to be tested, the top of the probe is pressed back for a certain distance, a spring is arranged in the probe to keep the top of the probe to be pressed on the surface of the skin under the pressure of 0.16N, and the result is displayed on the host within one second.

60 subjects with healthy skin were selected and divided into 12 groups of 5 subjects. After the subject was stood still for 30 minutes, the test site blank value was measured using a skin moisture test probe Corneometer CM825 from CK, germany, and 5 points were fixedly measured in each area in a predetermined order to obtain an average value. The subject then applied 0.5g of the test sample to the facial test site, removed makeup in the same manner for 2 minutes, rinsed clean, and started the timer. The MMV values were measured at each time point according to the experimental design, the MMV value change rates before and after the use of the cleansing oil were calculated, abnormal data were removed, and the average value of the MMV value change rates of each group was recorded in table 4.

Table 4 average value of MMV value change rate (%) -at different time points for each group of facial cleanser

From table 4, it can be seen that the moisturizing performance of comparative examples 3 to 7 is inferior to that of the examples, compared with example 3, the content of the vegetable oil used in comparative examples 3 to 7 is unchanged, and only one component is lacked, and the experimental result shows that the compounding of the five vegetable oils, namely olive oil, jojoba oil, oat kernel oil, sunflower seed oil and shea butter oil, has a synergistic effect, so that the moisturizing performance of the cleansing oil can be remarkably improved.

(3) Experience of use

The use experience evaluation of examples 1 to 9, commercial product 1 (Pitsuu amber refined cleansing oil) and commercial product 2 (FACNL quick cleansing oil) was carried out by 10 experts, the evaluation items included cleansing power, washability and freshness, the use experience of each item was 1 to 5 from poor to excellent, and the scoring criteria are shown in Table 5. The test method comprises the following steps: a non-stick cup of lipstick, oily mascara and oil-in-water powder were first primed on the face, 2h later, 2g of test sample was taken on a hand moistened with water, then smeared on the face, massaged for 40s, and then rinsed with warm water, and the average of each score result for each test sample was recorded in table 6.

TABLE 5

Scoring	Makeup removing ability	Washability of the agent	Degree of freshness
				1	The residual quantity of the color cosmetics after being smeared for 40 seconds is more than 2 percent	The facial cleanser can be washed for 30 seconds and a large amount of facial cleanser oil is adhered to the skin	Very greasy
2	The residual quantity of the color cosmetics after being smeared for 40 seconds is 1 to 2 percent	Equal amount of skin cleaning oil adhered to skin after 30 seconds of washing	Greasiness
				3	The residual quantity of the color cosmetic after being smeared for 40 seconds is 0.5 to 1 percent	The facial cleanser is washed for 30 seconds and a small amount of facial cleanser oil is attached to the skin	Not fresh and cool

				5	After being smeared for 40 seconds, the color cosmetics are washed without residue	The facial cleanser oil does not adhere to the skin after being washed for 30 seconds	Very fresh and cool

TABLE 6

As can be seen from Table 6, the cleansing oil prepared from the formulation of the present invention is generally superior to commercial product 1 and commercial product 2 in cleansing power. Furthermore, from the comparison of the effects of examples 1 to 9, it is clear that the ratios of the five components of isopropyl myristate, PEG-20 glyceryl triisostearate, PEG-8 caprylic/capric glycerides, water and dipropylene glycol have a great influence on the use experience of the cleansing oil, although the rinsing properties and the refreshing properties of examples 1 and 5 are not the same as those of other examples.
