Problems solved by technology

If the amount of preservative added is not enough, microorganisms may adapt to the surrounding growth environment and develop drug resistance, resulting in failure of preservatives
At present, most cosmetic companies use chemically synthesized preservatives, and chemically synthesized preservatives have the defects of high irritation and toxicity, and the safety is not very good

[0024] 1. The preparation method of Brazilian hematoxylin is as follows:

[0025] Weigh the Brazilian Sapphire medicinal material, wash, dry, and pulverize to obtain the Brazilian Sapphire medicinal material powder; add ethanol with a volume fraction of 95% according to the feed liquid 1:15, heat and reflux for extraction, and recover the solvent to obtain the Brazilian Sappanwood crude extract. Filtrate and extract the filter residue twice; then add ethyl acetate for extraction, and obtain brazil hematoxylin after recrystallization.

[0026] 2. the preparation method of chicory sesquiterpene lactone compound is as follows:

[0027] Weigh the chicory, after drying, add ethanol with a volume fraction of 85% according to the solid-liquid ratio of 1:15, repeat the extraction three times, combine the filtrate, concentrate under reduced pressure, add 2 times the amount of water to suspend; then extract with ethyl acetate , and concentrate the extracts under reduced pressure; throu...

Abstract

The invention discloses a preservative and application thereof. The preservative is prepared from the following components in percentage by mass: 0.2 to 2.5% of brazilin, 0.1 to 0.2% of cichorium intybus sesquiterpene lactone compound, and 0.2 to 2.3% of galangin. The preservative has the advantages that all raw materials are supplied from natural plants, the contained various functional ingredients are mutually coordinated and synergistic, and then the product can reach obvious corrosion-resistant effect; the preservative can be used as the cosmetic preservative to be applied to eye masks, and completely replace the use of chemical synthetic preservative, the product safety is improved, the irritation, allergy and side or toxic effect are avoided, and the influence on stability of cosmetics is avoided.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a preservative and its application. Background technique [0002] Preservatives are substances that prevent the growth of microorganisms. In cosmetics, the role of preservatives is to protect products from microbial contamination. Cosmetics are prone to deterioration due to microbial contamination, and under normal circumstances, it can be reflected in the appearance. For example, mold and yeast often appear moldy spots on the edge of product packaging; products contaminated by microorganisms appear turbidity, sedimentation, color change, pH value change, foaming, and odor. If it is an emulsion, it may break emulsion and become a block etc. If the amount of preservative added is not enough, microorganisms may adapt to the surrounding growth environment and develop drug resistance, resulting in failure of preservatives. At present, most cosmetic companies use chemically synthesized pr...
