Embodiment 1 to Embodiment 3

[0101]

[0102] The leaves of Azadirachta indica used in the examples of the present invention were purchased from TNHHSBJ Viet Nam Co.

[0103] In order to manufacture the hot water extract (AIW) applicable to Example 1, the process of using ultrapure water 10 times the weight of the dry sample as a solvent for 4 hours at 100°C for 4 hours was repeated three times, and then using filter paper (No. 20 filter paper, Hyundai micro Co., Ltd., Korea) The extract was filtered, followed by concentration, freeze-drying, and powdering.

[0104] In order to manufacture the 70% ethanol extract (AIE) applicable to Example 2 and the 70% acetone extract (AIA) applicable to Example 3, at first carry out at room temperature by repeating 3 times and utilizing a solvent of 10 times the weight of the dry sample 24-hour immersion extraction process to obtain the extract, and then follow the same method as the hot water extract to perform powdering on the remaining extract ( figure 1 ).

Abstract

The present invention relates to a cosmetic composition comprising an Azadirachta indica leaf extract. Specifically, disclosed are: a cosmetic composition comprising an Azadirachta indica leaf extractas an active ingredient and having antibacterial activity, anti-inflammatory activity, and anti-pollution activity, wherein the anti-pollution activity is the activity of preventing pollutants, finedust, or heavy metal particles in air from adsorbing onto the skin and protecting dermal cells; a cosmetic product composition comprising same; and a Pickering emulsion composition comprising an Azadirachta indica leaf extract.

Description

technical field [0001] The present invention relates to a cosmetic composition comprising neem leaf extract, a cosmetic composition comprising the aforementioned cosmetic composition, and a Pickering emulsion composition comprising neem leaf extract. Background technique [0002] Fine dust is a very fine granular substance with a diameter of less than 10 μm, which will have a great impact on the skin. When it is attached to the skin and mixed with oil, it will cause the deposition of waste, and when it penetrates into the pores and causes Heavy metals such as arsenic, cadmium, and lead may also cause skin problems such as acne and boils when mixed. Fine dust is more fatal to patients with skin diseases such as acne. In recent years, the number of patients with acne diseases has increased rapidly, and the age group affected by the disease has also expanded from the past teens to the twenties. The main reason is that The westernization of eating habits, the increased stress o...
