[0038] Example 1 Composition Antibacterial Experiment

[0039] 1. Material

[0040] 1.1 Test materials

[0041] Clove extract, Ginkgo biloba extract and Coptis extract were all extracted by our laboratory according to the following methods.

[0042] Clove extract: Take plant spice lilac flower as raw material and extract with water or water-ethanol. Crush the dried Chinese medicinal materials of cloves through a 100-mesh sieve, and use 85% ethanol as the extraction solvent according to the ratio of 15mL extraction solvent per gram of cloves. Incubate at 85°C for 2h, centrifuge and filter, and collect the filtrate, which is recorded as the first filtrate ; The filter residue is based on the ratio of 10mL extraction solvent per gram of filter residue, using 70% ethanol as the extraction solvent, incubating at 80°C for 3 hours, centrifuging, filtering, collecting the filtrate, and recording it as the second filtrate; combining the first filtrate and the second filtrate The filtrate was...

[0095] Example 3 Skin irritation test

[0096] 3.1 Human skin patch test of different concentrations of composition

[0097] The human patch test examines the possibility of the test substance causing adverse reactions to human skin. Refer to GB17149.1-1997 "General Principles of Diagnostic Standards and Treatment Principles for Cosmetic Dermatitis", GB17149.2-1997 "Diagnostic Standards and Principles for Treatment of Cosmetic Contact Dermatitis" and "Hygiene Standards for Cosmetics 2007" standards, according to the criteria for selection of subjects Choose to participate in the trial 30 people, aged 22-35 years old.

[0098] A total of 17 samples of each single component solution of different concentrations in Example 1.5.1 and the composition of Example 2 were used as test substances, and the amount of about 250 μL was put into the spot tester, and the control hole was a blank control (no substance was placed). The patch tester with the test substance was applied to the curved si...

Abstract

The invention discloses a corrosion-proof composition which comprises a combination of two or more of a clove extract, a gingko extract, a coptis root extract and sorbitan octoate. The composition has an inhibiting and killing effect on various bacteria and fungi. The composition cannot cause the problems such as skin allergy or pigment sediment, and skin yellowing, so that the composition is applicable to cosmetics. The invention discloses a cosmetic comprising the corrosion-proof composition at the same time.

Description

technical field [0001] The invention belongs to the field of natural products / cosmetics, and relates to a composition with antiseptic / antibacterial effects. Background technique [0002] Because cosmetics contain a variety of nutrients, they are extremely susceptible to microbial contamination during production, storage and use, which in turn leads to product deterioration such as turbidity, precipitation, color change, foaming, and odor. Once the product deteriorates, some efficacy components Components may be decomposed into substances that are irritating to human skin, making the commercial value of the product lose. If cosmetics are contaminated by pathogenic bacteria, such pathogenic microorganisms and their metabolites will affect human health. Therefore, it is of great significance to add an appropriate amount of preservatives, which can effectively prevent the product from being polluted and multiplied by microorganisms, and ensure the safety and hygienic quality of...
