[0005] Preferably, the chamomile extract powder, hawthorn extract powder, chicken gizzard membrane extract powder and astragalus extract powder are all prepared by supercritical CO2 extraction combined with freeze-drying process.

[0006] Preferably, the supercritical CO2 extraction conditions of chamomile are as follows: pressure 20-30 MPa, temperature 35-45℃, extraction time 2-3h; before extraction, use 5%-10% ethanol solution for 1-2h of infiltration pretreatment of chamomile powder.

[0007] Preferably, the total content of linalool and linalyl acetate in the lavender essential oil is not less than 80%; the content of terpinen-4-ol in the tea tree essential oil is 30%-40%.

[0008] Preferably, the composite essential oil further comprises 0.5-1 parts of lemon essential oil.

[0009] The application further discloses a preparation method of the essential oil for infant massage.

[0010] S1: raw material pretreatment: chamomile, hawthorn, chicken gizzard and astragalus are respectively cleaned, dried to a water content of less than 5%, crushed and sieved through a 100-mesh sieve to obtain raw material powder;

[0011] S2: extract preparation: the raw material powder obtained in step S1 is respectively extracted by using a supercritical CO2 extraction technology, and the extract is freeze-dried to obtain corresponding extract powder;

[0012] S3: mixing and blending: under the protection of inert gas at 25-30 DEG C, composite base oil is first added into a reaction kettle, and after being uniformly stirred, lavender essential oil, tea tree essential oil and mint essential oil are sequentially added, and stirred for 20-30 min; then the extract powder prepared in step S2 is added, and stirred for 30-45 min to make it fully dispersed; finally, vitamin E is added, and stirred for 15-20 min;

[0013] S4: post-treatment: the mixture obtained in step S3 is filtered through a 0.22-micron microporous filter, and filled into brown glass bottles under the protection of nitrogen.

[0014] Preferably, in step S3, 0.5-1 part of lemon essential oil is added before the addition of vitamin E, and stirred at a rotating speed of 100-150 r / min for 5-10 min.

[0015] Preferably, in step S4, the packaging bottle is subjected to nitrogen blowing before filling, so that the oxygen concentration in the bottle is reduced to below 0.5%.

[0016] The application adopts the above structure and achieves the following beneficial effects:

[0017] (1) through the combination of essential oils (lavender, tea tree and mint), composite base oil (sweet almond oil and olive oil) and four kinds of traditional Chinese medicine extracts (chamomile, hawthorn, chicken gizzard and astragalus), the comprehensive effects of relaxation and comfort, antibacterial cleaning, spleen-invigorating and food-digesting and physical strengthening are realized, the components produce synergistic effects, and the effect is better than that of single component.

[0018] (2) the pH value (6.5-7.5) of the product is controlled in the suitable range of children's skin; high-quality and low-irritation raw materials are selected; and experiments prove that the product has extremely low skin irritation, and meets the use standard of infants.

[0019] (3) through the low-temperature mixing process, the addition of vitamin E and the nitrogen protection filling, the product has high antioxidant property (DPPH clearance rate is greater than or equal to 85%), and it is ensured that the active ingredients do not significantly decrease within 12 months of storage.

[0037]

[0038]

[0039] The antioxidant capacity of the complete formula of the application is significantly higher than the simple superposition of any single component or part of the component (p<0.01), which proves that there is a significant synergistic effect between the components, and the high antioxidant property means that the product is more stable, and the shelf life of the effective components is longer.

[0040] Experimental Example 2: Skin irritation test

[0041] According to the skin irritation / corrosion test method in the “Cosmetic Safety Technology Specification” (2015 edition), multiple skin irritation tests were conducted:

[0042] Sample: composite essential oil prepared in Example 1 of the application;

[0043] Method: healthy white rabbits were selected, and the sample was applied after shaving, and the skin reaction was observed after continuous application for 14 days;

[0044] Results: During the whole experiment, no erythema, edema and other abnormal reactions were observed on the application sites of the rabbits, and the average score of skin irritation was 0.2, which was far below the mild irritation standard of 1.0, indicating that the product of the application had no skin irritation.

[0045] Experimental Example 3: Accelerated stability test of the product

[0046] The product of the application was placed in a constant temperature and humidity chamber at 40℃±1℃ and relative humidity of 75%±5%, and an accelerated test was conducted for 3 months

[0047] Detection index: appearance, odor, pH value, DPPH clearance rate.

[0048] Results: After the end of the test, the appearance and odor of the product had no change, the pH value was maintained at 7.1, and the DPPH clearance rate remained above 86%. According to the accelerated test results, the shelf life of the product at room temperature can be up to 24 months or more.

[0049] The above describes the application and its embodiments, which are not limiting. In general, if a person skilled in the art is inspired by it, without departing from the purpose of the application, without creative design, similar structural ways and embodiments of the technical solutions can be obtained, which should all belong to the protection scope of the application.
