The application discloses a method for preparing a Melissa extract and the Melissa extract and a cosmetic composition. The method comprises the following steps: a crushing step, crushing a Melissa raw material to obtain a Melissa crushing product; an extraction step, extracting the Melissa crushing product with a mixed solution of alcohol and water to obtain a crude extract; a filtration step, filtering the crude extract with a filter membrane to obtain a filtrate; a concentration step, vacuum-concentrating the filtrate to remove part of alcohol and water, and obtaining a crude extract paste; a resin purification step, loading the crude extract paste into an adsorption resin column, performing water elution and gradient resolution of an alcohol aqueous solution, and obtaining an eluate; a decolorization step, adsorbing and decolorizing the eluate with activated carbon, and filtering to obtain a decolorized liquid; and a concentration and drying step, concentrating and drying the decolorized liquid to obtain a powder-like Melissa extract. The method is used to prepare a nano-powder-like grade Melissa extract, and the coumarin content in the extract is lower than a detection limit.

This invention relates to a hot spring water emulsion and its preparation method. The hot spring water emulsion comprises, by weight percentage, the following components: hot spring water: 2-80%, thickener: 0.1-1%, emulsifier: 4-30%, moisturizer: 5-20%, and the balance being water. The hot spring water emulsion prepared by this invention is not only lightweight, quick-drying, and rapidly absorbed, with a refreshing feel and good stability, but also possesses excellent moisturizing, soothing, and skin barrier repair effects. Furthermore, it requires no additional emulsifiers, significantly reducing skin irritation.

The invention belongs to the technical field of plant extracts and cosmetic raw materials, and particularly relates to an artemisia annua extract based on a deep-eutectic solvent as well as a preparation method and application of the artemisia annua extract. The preparation method of the artemisia annua extract comprises the following steps: simultaneously putting artemisia annua powder and an eutecticevaporate extraction solvent consisting of betaine and 1, 3-propylene glycol into a micro-jet extractor, controlling the temperature to be 20-30 DEG C, carrying out mixed extraction, and discharging to obtain an artemisia annua primary extracting solution; and centrifuging and filtering the obtained artemisia annua primary extracting solution to obtain the artemisia annua extract. According to the method disclosed by the invention, the artemisia annua is extracted by jointly utilizing a low-temperature micro-jet technology and the eutectic solvent, and by selecting the eutectic extraction solvent with high specificity, the extraction efficiency of specific polyphenol and flavone components in the artemisia annua is higher than that of a conventional extraction process and eutectic extraction solvents with other components; and the physiological activity of the obtained extract is stronger.

This invention discloses a soothing and repairing composition and its application in cosmetics, belonging to the field of cosmetic technology. The soothing and repairing composition contains water lily polysaccharide, fibroin, and Paris polyphylla extract; the mass ratio of water lily polysaccharide, fibroin, and Paris polyphylla extract is (50~250):(100~500):(10~100). The above-mentioned soothing and repairing composition can synergistically inhibit the overexpression of key inflammatory factors (such as NO, IL-6, TNF-α) through multiple mechanisms, while promoting the repair of the skin barrier, thereby achieving excellent soothing and repairing effects with low irritation, and is particularly suitable for sensitive skin and acne-prone skin. Cosmetics containing the above-mentioned soothing and repairing composition can also achieve good soothing and repairing effects and are also suitable for sensitive skin and acne-prone skin.

The application discloses a kind of fermented vegetable oil and its production method.The application belongs to resting cell whole-cell enzymatic fermentation process: first by high-density fermentation to obtain yeast bacteria liquid, then separation and washing to obtain clean high-activity yeast bacteria, high-activity yeast bacteria, water, vegetable oil are mixed according to proportion, under specific temperature, oxygen supply and pH condition, by whole-cell enzymatic fermentation process using resting yeast bacteria to ferment vegetable oil, after fermentation, secondary centrifugal filtration is obtained fermented vegetable oil.Compared with the fermented vegetable oil obtained by conventional microbial fermentation process, the fermented oil obtained by the application has less impurities, lighter color, cleaner oil, lower ash content, stronger oxidation stability, longer shelf life and other advantages, and compared with natural vegetable oil crude oil, it is rich in free fatty acids, flavonoids, polysaccharides and natural glycolipids, has better skin moisturizing, repairing, soothing and antioxidant effects, and has good economic value and application prospect in the field of beauty and skin care.
