preparation example Construction

[0021] The honeysuckle extract is prepared by a preparation method comprising the following steps: after grinding the honeysuckle, taking an appropriate amount into a soaking tank and adding a certain proportion of propylene glycol aqueous solution, the solid-liquid ratio of the honeysuckle and the propylene glycol aqueous solution is 1:5-1: 60. The mass ratio of water to propylene glycol in the propylene glycol aqueous solution is 2-1:1-4, stir and soak for 8-24 hours, then transfer the treatment liquid into the extraction tank for microwave extraction, the extraction time is 5-40 minutes, and the extraction temperature is 25-125°C, microwave power 300-1500W, filter the extract to obtain honeysuckle extract.

[0022] The preferred preparation condition is that the solid-liquid ratio of honeysuckle and propylene glycol aqueous solution is 1:20, the mass ratio of water and propylene glycol in the propylene glycol aqueous solution is 1:4, stir and soak for 12 hours, then transfer...

Abstract

The invention discloses a preparation method of a honeysuckle extract meeting cosmetic formula requirements and an application of the honeysuckle extract to preservative-free cosmetics. According to the preparation method, a humectant propylene glycol for cosmetics is innovatively used as an extracting solvent, the honeysuckle extract is obtained under specific preparation conditions, and hazards of an organic solvent used in conventional extraction are avoided. The extract has preservative and antibacterial functions, and 0.05%-30% of the extract is added to cosmetics and can be taken as a plant-sourced preservative component for preparation of the preservative-free cosmetics. The used solvent is a common humectant for the cosmetics, is safe and non-toxic and has a skin care effect.

Description

technical field [0001] The invention relates to the field of plant extracts and cosmetics, in particular to a method for extracting honeysuckle extract suitable for cosmetics, and the extract is used as an antiseptic and antibacterial component in cosmetics. Background technique [0002] Honeysuckle, also known as honeysuckle flower, double flower, and two treasure flower, is a traditional Chinese medicinal material commonly used. It mainly contains volatile oil, flavonoids, organic acids, triterpenoids and inorganic elements. Modern pharmacological research has found that honeysuckle has three major functions: anti-pathogenic microorganisms, enhancing immune function, and anti-inflammatory and antipyretic effects. Honeysuckle extract added to cosmetics has the effects of antibacterial and soothing, delaying aging, and preventing damage caused by ultraviolet rays. [0003] A number of patents have been authorized for the research results of microwave-assisted extraction te...
