Embodiment 1
[0057] Example 1: Preparation of extracts from natural substances
[0058] 1-1. Preparation of Pepper Fruit Extract, Pulsatilla Pulsatilla Extract, Usnea Extract, Bamboo Stem Extract and Pinus Longleaf Extract
[0059] After pulverizing 100 g of the pepper fruit, put 1 liter of purified water into it, and extract while ultrasonically treating it at 50° C. for 72 hours. Sonication was performed for 10 minutes every 2 hours. Except that the raw materials are different, the extracts of Pulsatilla pulsatillae, Usnea chinensis, bamboo stems of green bark and pine needles of long leaves are prepared by the same method as the preparation method of the chinensis extract. In the above preparation process, 100g of Pulsatilla pulsatillae, 100g of Usnea 100g, 100g of green bamboo stems or 100g of long-leaved pine needles were used as raw materials. As a result of the extraction, 935 ml of the extract of chinensis, 935 ml of the extract of Pulsatilla chinensis, 935 ml of the extract of U...

[0069] Experimental Example 1: Evaluation of antiseptic efficacy of individual preservatives
[0070] Due to the characteristics of the cosmetics field where products are circulated at room temperature and microorganisms are continuously inoculated after opening, in order to ensure the quality of cosmetics, it is important to use appropriate preservatives. Among the antiseptic effects, the bactericidal effect of microorganisms is extremely important. In order to confirm the microbial bactericidal effect of the plant-derived extract, the following experiments were performed.
[0071] In order to confirm the antiseptic effect of the (A) chrysanthemum, Pulsatilla, Usnea mixed extract and (B) grapefruit seed, green bamboo stem, long-leaved pine needle mixed extract of embodiment 1-2, relative to 100% by weight After the cosmetic composition containing 0.125% by weight to 2% by weight of each mixture, the minimum inhibitory concentration (MIC, minimalinhibitoryconcentration) of the...
experiment example 2
[0074] Experimental example 2: Evaluation of the bactericidal effect of microorganisms when mixing preservatives
[0075] As mentioned earlier, in order to obtain a sufficient bactericidal effect suitable for the field of cosmetics, mix "Qinjiao fruit, Pulsatilla pulsatillae, Usnea mixed extract" and "Grapefruit seed, green bamboo stem, Long-leaved pine needle leaf mixed extract", after making the mixture (hereinafter described as "the mixture of Experimental Example 2"), by the same method as Experimental Example 1, the minimum bactericidal concentration (MBC) to coliform bacteria and mold was detected value.
[0076] The result is as figure 2As shown, there is not much difference in the bactericidal effect to coliform bacteria, but for mould, the mixture of this experiment example 2 is 0.167% at 0.25% (" the content of " Qinjiaoguo, Pulsatilla pulsatillae, Usnea mixed extract ", " grapefruit More than 99.9% were killed under the concentration of seed, green bark bamboo st...
