[0095] The raw material composition of each cosmetic is shown in Table 1 below, measured in mass percentage.

[0096] Table 1: Raw material composition

[0097]

[0098]

[0099] Among them, the camellia oil in cosmetics 1 and 3-6 in Table 1 is the camellia oil 1 prepared above; and the camellia oil in cosmetic 2 is the camellia oil 2 prepared above.

[0100] The difference between cosmetics 7-11 and cosmetics 1 is that the camellia oil 1 in cosmetics 1 is replaced by the camellia oil 3-7 prepared above.

[0101] The preparation method of the cosmetic is as follows:

[0102] Camellia seed oil, celery seed extract, avocado oil and polyol are heated at 60°C and stirred at 80rpm for 0.5 hour to obtain an oil phase; water, hexadecyltrimethylammonium chloride, cocoyl ethyl glucoside and PPG-5-laureth-5 are heated at 45°C and stirred at 70rpm for 0.4 hour to obtain an aqueous phase; the oil phase is added to the aqueous phase, heated at 50°C and stirred at 75rpm for 0.5 hour, cooled to 35°C, and then liquorice extract, thickener, pH adjuster and preservative are added, stirred at 80rpm for 0.4 hour, sterilized to obtain the cosmetic.

[0103] 3. Testing

[0104] 1. Stability test

[0105] Deionized water and the above cosmetics were stirred at 800 rpm and 35°C for 1 hour in a mass ratio of 98:2, and then left to stand at room temperature for 0.5 hours, and then the Zeta potential ζ1 was tested. Then, the mixture was sealed and stored in a 50°C constant temperature box for 48 hours, and the Zeta potential ζ2 was tested again. The average value was taken for 3 parallel tests, and the results are shown in Table 2. Among them, the larger the absolute value of the Zeta potential ζ, the better the stability.

[0106] Table 2: Zeta potential

[0107]

[0108]

[0109] Combined with the test data of cosmetics 1-6 in Table 2, it can be seen that the cosmetics prepared by the present invention have good stability, and have good stability at room temperature and high temperature.

[0110] According to the tests of cosmetics 1, 3-4, the combination of cocoyl ethyl glucoside and PPG-5-laureth-5 in cosmetics can mutually enhance the stability and thermal stability of cosmetics, and the combination of the two produces a nonlinear superposition effect.

[0111] According to the tests on cosmetics 1, 5-6, changing the mass ratio of cocoyl ethyl glucoside to PPG-5-laureth-5 in the cosmetics will result in different stabilities of the cosmetics obtained, and when the ratio is 1.1-1.7:1, the stability of the cosmetics obtained is better.

[0112] 2. Combing test

[0113] 2.1 Wet combing test

[0114] Wet combing test: Divide the hair bundles from the same source into 11 parts, and use the above cosmetics 1-11 for experimental tests. The specific method is: wash each group of hair bundles, and then use 0.8g of cosmetics 1-11 to rub them evenly, leave them for 3 minutes, rinse them with clean water, and then dry them naturally; repeat the above experimental process every 3 days, for a total of 10 times; on the third day after the above process is carried out 7 times, use 0.8g of cosmetics 1-11 to rub them evenly, leave them for 3 minutes, rinse them with clean water, comb them with a comb to remove residual moisture, and then measure the wet combing resistance A in a micro tensile tester; measure them in parallel 6 times and take the average value. The results are shown in Table 3. The smaller the wet combing resistance, the better the hair scales are repaired and the smoother the hair bundles.

[0115] Table 3: Wet combing test

[0116] Experimental testing A / g Cosmetics 1 152.63 Cosmetics 2 153.25 Cosmetics 3 158.71 Cosmetics 4 160.36 Cosmetics 5 154.82 Cosmetics 6 156.17 Cosmetics7 170.94 Cosmetics 8 159.13 Cosmetics 9 161.58 Cosmetics 10 155.43 Cosmetics11 157.64

[0117] 2.2 Dry combing test

[0118] Dry combing test: After the wet combing test, the hair was air-dried and then the dry combing resistance B was measured on a micro tensile tester; the test was repeated 6 times in parallel and the average value was taken. The results are shown in Table 4. The smaller the dry combing resistance, the better the hair scales are repaired and the smoother the hair.

[0119] Table 4: Dry combing test

[0120]

[0121]

[0122] It can be seen from the tests in Tables 3-4 that the cosmetics prepared by the present invention have a good hair scale repair effect, impart excellent combing properties to the hair, and make the hair smoother.

[0123] Combined with the tests on cosmetics 1 and 7-11, it can be seen that by changing the extraction method of camellia seed oil, the combing effect of the prepared cosmetics changes. In other words, the camellia seed oil obtained by the specific preparation process of the present invention has a better hair flake repairing function.

[0124] According to the tests of cosmetics 1 and 7, extraction with 60-75wt% ethanol aqueous solution can make camellia seed oil have better hair maintenance effect and make hair combing easier.

[0125] According to the tests of cosmetics 1, 8-11, it can be seen that the use of ethyl acetate and chloroform as an organic phase for extraction can make the prepared camellia oil have a better effect on hair maintenance and give cosmetics a better effect of smoothing hair, compared with using only one of them as an organic phase for extraction to prepare camellia oil. The camellia oil prepared from the organic phase obtained by using ethyl acetate and chloroform in a volume ratio of 1:2-4 gives cosmetics a better effect of smoothing hair.

[0126] According to the tests on cosmetics 1, 3-6, the combination of cocoyl ethyl glucoside and PPG-5-laureth-5 can better soften the hair compared to the cosmetics prepared by either one of them. The reason is that the combination of the two can effectively deliver or penetrate the active ingredients into the hair better, resulting in better hair care effects.

[0127] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
