Problems solved by technology

Korean Laid-Open Patent No. 2005-41745 (Patent Document 2) discloses a preservative composed of 1,2-hexanediol and cosmetics containing it, but it needs to be used in large quantities in order to exert a sufficient effect
Due to the side effects such as skin irritation caused by such a large amount of use, and problems such as the feeling of use which are decisive factors of quality, etc., its use is extremely popular among those skilled in the production of cosmetics and other external skin preparation products. limit
[0005] On the other hand, although extracts from natural substances are tried to be used as preservatives, when extracts from natural substances are used as preservatives, the preservation effect of the product is weak, and sufficient antiseptic strength cannot be exerted. When used in large quantities, Unable to maintain the emulsified dosage form, or reduce the quality of the product due to discoloration and odor, so use it very little

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...

Abstract

The invention relates to a preservative composition containing natural extracts. Compared with the current preservative composition, the preservative composition of the invention has equal preservative effect. The side effects on the skin are reduced to the most extent. The natural preservative composition has low stimulation and low toxicity, and can be used as the preservative composition in the natural cosmetics, infant cosmetics and sensitive skin cosmetics.

Description

technical field [0001] The present invention relates to natural preservation compositions containing extracts from natural substances. Background technique [0002] In the field of food to cosmetics, microbiological stability is very important for long-term preservation of products. Especially for cosmetics, most products are circulated at room temperature and are continuously inoculated with microorganisms after opening. Therefore, it is necessary not only to inhibit the growth of microorganisms, but also to have a bactericidal effect. Therefore, in order to maintain the quality of cosmetics, it is important to use an appropriate preservative with excellent bactericidal effect. [0003] As preservatives, synthetic preservatives or natural preservatives are used. Synthetic preservatives have excellent bactericidal effects, but are also confirmed to be toxic to skin cells. In addition, the microbial bactericidal effect of natural preservatives is very small, so they are no...
