Wormwood extract, preparation method of wormwood extract, and composition and tear-off mask containing wormwood extract

Abstract

The invention belongs to the field of daily chemicals. A preparation method of a wormwood extract comprises the following steps: cleaning and disinfecting wormwood plants, performing natural fermentation, shearing into powder at a high speed after fermentation, putting into a reaction kettle, adding ethanol, butanediol, glycerol and water, and performing vacuumizing, heating, condensing, refluxing, heat-preservation extraction and filtering to obtain filtrate; performing rotary evaporation on the filtrate, concentrating the filtrate to 20-50% of the original volume, and recovering ethanol to obtain a concentrated solution; diluting the concentrated solution by using water or a concentrated ethanol water solution, and performing adsorption by using macroporous adsorption resin for purifying and eluting; and performing rotary evaporation on the eluent. The preparation method in the invention is simple and efficient; the finished product yield of the extracting solution is not lower than 56%; and the purity is 3-20%. The extract is applied to the composition to resist inflammation and allergy, and is applied to a tear-off mask to reduce the irritation of the mask to the skin and reduce the allergy risk of the mask.

Description

technical field [0001] The invention belongs to the field of daily chemicals, and in particular relates to a wormwood extract, a preparation method thereof, a composition containing the same and a tear-off mask. Background technique [0002] The tear-off mask has a good effect on removing the aging stratum corneum, but the tear-off mask is easy to cause enlarged pores or some skin allergies, and because it needs to shorten the residence time of the mask to allow it to form a film quickly, most mask products need to add ethanol To accelerate its film formation, it is more likely to cause skin sensitivity problems. Therefore, in order to meet the needs of consumers, it is necessary to develop a tear-off mask that has good effect on removing the aging cuticle, is mild and low-irritating, and can repair skin sensitive problems. [0003] Wormwood, also known as Bingtai, Xiangai, Ai Xiao, Mugwort, etc., is a perennial herb or slightly semi-shrub-like, and the plants have a strong...
