Problems solved by technology

[0005] The present invention aims to overcome the problem that traditional cosmetics rely on chemical synthesis, long-term use will have a certain impact on human health, and the shelf life is short, and they are easy to deteriorate due to microbial contamination after unpacking, and provide a clove extract used in the preparation of cosmetics. The application of clove extract is a natural plant extract, the natural components are more easily absorbed by the skin, and have high safety performance; adding the crude extract of clove to cosmetics can effectively prevent cosmetic deterioration caused by microbial contamination ; and can relieve skin problems caused by fungi, and has certain anti-oxidation and anti-aging functions

Abstract

The invention relates to the technical field of cosmetic preparation, and discloses application of a clove extract to preparation of cosmetics. The addition amount of the clove extract in the cosmetics is 1-5% (w / w), and the clove extract is added in a form of slow-release particles. An extraction method of the clove extract comprises the steps that clove powder and a solvent are mixed, ultrasonicassisted extraction is conducted under the water bath heating condition, then incubation is conducted at 130-160 rpm and at 37 DEG C for 20-30 hours, filtration is conducted, and after the solvent isremoved by rotary evaporation, the clove extract is finally obtained. The clove extract is added into the cosmetics, and thus the situation that the cosmetics go bad due to microbial pollution can beeffectively prevented; the clove extract has an antifungal effect, and the cosmetics with added eugenol can alleviate skin problems through the effect; and in addition, the clove extract further hasa certain anti-oxidation function, so that the cosmetics have the anti-oxidation and anti-aging functions.

Description

technical field [0001] The invention relates to the technical field of cosmetic preparation, in particular to the application of a clove extract in the preparation of cosmetics. Background technique [0002] In recent years, plant extract cosmetics with less side effects and less toxicity are more and more popular. Under this trend, cosmetics with plant extracts as active ingredients are bound to have broad market prospects. Plant extracts refer to plant products with small biological molecules and macromolecules as the main body, which are formed for the purpose of separating and purifying one or more active ingredients in plant raw materials by physical, chemical and biological means. Compared with traditional cosmetics, cosmetics formulated with plant extracts as active ingredients have many advantages: it overcomes the shortcomings of traditional cosmetics relying on chemical synthesis, making the product safer; natural components are more easily absorbed by the skin, ma...
