[0074] Experimental Example 1

[0075] Stability test

[0076] 100 mL of the hair care compositions of Examples 1-3 and Comparative Examples 1-12 were respectively poured into transparent bottles to 80% of the height, and stability tests were performed at different temperatures, with 3 parallel tests at each temperature.

[0077] The stability test method is:

[0078] (1) Incubate in a 45°C constant temperature incubator for 2 months. If there is no stratification or obvious discoloration, it is considered qualified.

[0079] (2) If there is no delamination or obvious discoloration after 3 months of inspection at room temperature, the product is considered qualified.

[0080] (3) Incubate in a 5°C constant temperature incubator for one month. If there is no stratification, it is considered qualified.

[0082] The stability test results show that the hair care compositions of Examples 1-3 and Comparative Examples 1-10 are not stratified and have no obvious changes when tested at 45°C, room temperature, 5°C and -15°C, so the hair care compositions of Examples 1-3 and Comparative Examples 1-10 have good stability. However, the hair care compositions of Comparative Examples 11 and 12 are slightly stratified when tested at 45°C, and have poor stability. This shows that the present invention can significantly improve the stability of the hair care composition by adjusting the parameters of temperature and rotation speed.

[0083] Experimental Example 2

[0084] Safety Testing

[0085] Conduct skin occlusive patch test in accordance with the "Technical Specifications for Safety of Cosmetics" (2015 edition).

[0086] 450 subjects were selected and divided into 15 groups on average. There was no significant difference in skin between the groups, so the groups were comparable.

[0087] The hair care compositions of Examples 1-3 and Comparative Examples 1-12 were respectively placed in a spot tester, and the spot tester was applied to the curved side of the forearm of each group of subjects. The skin reaction was observed 0.5h, 24h, 48h, and 72h after removal.

[0088] The results of the skin occlusive patch test showed that the hair care compositions of Examples 1-3 and Comparative Examples 1-12 all showed negative reactions, indicating that the hair care compositions of Examples 1-3 and Comparative Examples 1-12 were highly safe.

[0089] Experimental Example 3

[0090] Dry combing test

[0091] 16 strands of damaged hair (5 g per strand, 20 cm in length) were selected, and there was no significant difference between the strands, which was comparable. A 10% sodium lauryl sulfate solution was prepared, and the hair strands were cleaned and massaged with 2 mL of the sodium lauryl sulfate solution for 1 minute, rinsed in tap water for 1 minute to avoid hair tangling, and dried for 12 hours.

[0092] One of the bundles was used as a blank control, and the other bundles were rubbed with 2 drops of the hair care composition of Examples 1-3 and Comparative Examples 1-12 on the palm, and then evenly applied to the hair from the middle to the ends. The combing performance was tested at 23° C. and a relative humidity of 65% 6h and 12h after use to obtain the maximum combing force after using the sample to be tested. Each bundle was tested 3 times and the average value was taken. The specific results are shown in Table 1.

[0093] Table 1 Dry combing performance of the hair care compositions of Examples 1-3 and Comparative Examples 1-12

[0094]

[0095]

[0096] As can be seen from the results in Table 1, the combing force maximum values ​​of the hair care compositions of Examples 1-3 of the present invention are the lowest, indicating that the hair care compositions of Examples 1-3 can significantly improve the softness of the hair, repair the damage to the hair scales on the surface of the hair, improve the texture and structure of the hair, and can maintain the softness of the hair for a long time. Example 1 can effectively reduce the maximum combing force relative to Comparative Example 1, indicating that the extraction method of the avocado fruit extract of the present invention can improve the softness of the hair and repair the damage to the hair scales on the surface of the hair. Relative to Comparative Examples 2-8, Example 1 can effectively reduce the maximum combing force, indicating that the components of seabuckthorn fruit oil, avocado fruit extract, argania spinosa kernel oil, deep sea two-jointed seed oil, jojoba seed oil, squalane and avocado fruit fat have a synergistic effect in improving the softness of the hair and repairing the damage to the hair scales. Relative to Comparative Examples 9-10, Example 1 can effectively reduce the maximum combing force, indicating that the dosage ratio of each component has a decisive influence on the softness of the hair. Compared with Comparative Examples 11-12, Example 1 can effectively reduce the maximum combing force, indicating that the stirring temperature and rotation speed of the components can affect the softness of the hair and the ability to repair damaged hair scales on the hair surface, and by improving the stability of the hair care composition, the softness of the hair is maintained for a long time. Based on the above results, it can be seen that the hair care composition obtained by the technical solution of the present invention can significantly improve the softness of the hair and improve the ability to repair damaged hair scales on the hair surface.

[0097] Experimental Example 4

[0098] Sensory evaluation

[0102] 450 subjects who met the inclusion criteria were selected and randomly divided into 15 groups. There was no significant difference between the groups, which was comparable. The 15 groups of subjects used the hair care compositions of Examples 1-3 and Comparative Examples 1-12, respectively. The method of use was: 8 drops of the hair care compositions were applied to the ends of the hair every 3 days. After one month of use, the subjects conducted sensory evaluation on combability, softness, smoothness and liking. The sensory evaluation indexes are shown in Table 2. A 10-point scoring method was used, with a score of 1-10. The sensory evaluation results are shown in Table 3.
