Embodiment 1

[0055] Embodiment 1 plant extract and preparation method thereof

[0056] Plant Extract #1:

[0057] Take 16kg of licorice roots, 18kg of eucalyptus leaves, 20kg of solitary roots, and 22kg of perilla leaves, mix them, grind them, and pass through a 40-mesh sieve; use 40% ethanol to extract in an extraction tank to obtain a preliminary extract; carry out ultrafiltration on the preliminary extract Membrane concentration and separation to obtain a concentrated extract; dry the concentrated extract to obtain a plant extract, and dissolve the plant extract in 500 kg of water to obtain plant extract #1.

[0058] Plant Extract #2:

[0059] Get 16kg of licorice roots, 18kg of eucalyptus leaves, 20kg of solitary roots, and 22kg of perilla leaves, respectively crush them and pass through a 40-mesh sieve; use 40% ethanol to extract respectively in the extraction tank to obtain four preliminary extracts; The liquid was concentrated and separated by ultrafiltration membrane to obtain fo...

Embodiment 2

[0072] Antibacterial experiment of embodiment 2 plant extract

[0073] The minimum inhibitory concentration (MIC value) was used to measure the antibacterial effect of the plant extract (ie stock solution) prepared in Example 1 on common pathogenic bacteria.

[0074] The tested strains were Staphylococcus aureus (ATCC6538), Escherichia coli (ATCC 8739), Pseudomonas aeruginosa (ATCC 16404), Candida albicans (ATCC 10231), Aspergillus niger (ATCC 16404), Malassezia furfur (ATCC44344), Propionibacterium acnes (ATCC6919);

[0075] (1) The minimum inhibitory concentration for inhibiting Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Candida albicans adopts the microplate method.

[0076] Add 100 μL of Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans bacteria liquid and 100 μL of plant extract (any one of the extracts prepared in Example 1 is concentrated in equal proportions according to the MIC method or Dilution), simultaneo...

Embodiment 3

[0085] The mite removal experiment of embodiment 3 plant extract

[0086] The male and female adults and nymphs of Dermatophagoides farinage were used as the tested mite species. Each plant extract prepared in Example 1 after dilution was used as the test agent respectively, and each plant extract was used to act on 500 mites, and the mite mortality was observed for 2min, 5min, 10min, 30min, 1h, and 3h. The results are shown in Table 2:

[0087] Table 2 Plant Extract Ability Test for Mite Removal

[0088]

[0089] It can be seen from Table 2 that plant extract #1 has the best lethal effect on mites, and the lethality rate can reach 90.5% after 2 minutes of action, and all mites can be killed within 5 minutes. The lethal effect of plant extract #2 on mites is second, the lethality rate reaches 86.4 in 2 minutes, 99.9 in 5 minutes, and all can be killed in 10 minutes. The lethal effect of plant extract #3, plant extract #4, plant extract #5 and plant extract #6 on mites is...

Abstract

The invention discloses an application of a plant extract in preparation of cosmetics with bacteriostatic and acarus killing functions, which belongs to the technical field of cosmetics. The plant extract is prepared from 10 to 15 parts by weight of licorice root extract, 16 to 22 parts by weight of eucalyptus leaf extract, 16 to 25 parts by weight of radix angelicae pubescentis root extract, 20 to 25 parts by weight of perilla leaf extract and 200 to 500 parts by weight of water. The cosmetic prepared from the plant extract has a strong inhibition effect on various pathogenic bacteria and a very good mite killing effect, and the prepared cosmetic is rich in natural products, does not contain substances irritating to skin, avoids skin itch caused by use, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to the application of a plant extract in the preparation of cosmetics with antibacterial and mite-removing functions. Background technique [0002] Acarids are a class of tiny animals belonging to the phylum Arthropoda Arachnida, subclass Acari. It is a general term for all species of Acari except ticks. The body size is generally about 0.5 mm, and some are as small as 0.1 mm. mm, most species are less than 1mm. There are many kinds of mites, they multiply quickly, and they are likely to become a disaster. Mites can be found in almost every corner of our lives. The common types of mites are leather mites, acaroid mites, house dust mites, chiggers, scabies, demodicids, and pus mites. [0003] Mites can parasitize on human skin and are very harmful to human health. They not only bite people and suck blood, invade the skin, but also cause dermatitis, rash, mite disease ...
