Embodiment 1-4

[0069] The amount described in the following table (the percentage in the following table is mass percent) will oil of lemon eucalyptus (purchased from Guangzhou Baihua Spice Co., Ltd., limonyl eucalyptol content is about 90% by weight) and listed in the following table The 1,2-alkanediols were mixed together, and the antiseptic effect of the mixture was evaluated by the zone of inhibition method. The results are listed in Table 1:

[0070] Table 1 Comparative results of antibacterial zones of lemon eucalyptus oil and 1,2-alkanediol compound

[0071]

[0072]

[0073] It can be seen from the data in the above table that after lemon eucalyptus oil is compounded with one or more 1,2-alkanediols, compared with the original system, the inhibition zone against mixed bacteria and molds is greater than the mathematical average of the original system , indicating that both the ability to inhibit mixed bacteria and the ability to inhibit mixed bacteria have been significantly im...

Embodiment 5-7

[0075] Amount described in the following table (percentage in the following table is mass percentage) oil of lemon eucalyptus (same as in the embodiment 1-4) and the common cosmetic preservative listed in the following table are mixed together, press The zone of inhibition method was used to evaluate the antiseptic effect of the mixture. The results are listed in Table 2:

[0076] Table 2 Comparative results of antibacterial zones of lemon eucalyptus oil and commonly used cosmetic preservatives

[0077]

[0078]

[0079] From the data of Examples 5-6, it can be seen that after lemon eucalyptus oil is compounded with one or more commonly used cosmetic preservatives, compared with the original system, the inhibition zone to mixed bacteria and mold is greater than the mathematics of the original system The average value shows that both the ability to inhibit mixed bacteria and the ability to inhibit mixed bacteria have been significantly improved. As can be seen from the ...

Embodiment 8-19

[0081] In order to verify the antiseptic efficacy of the compound containing lemon eucalyptus oil and the above additives added to cosmetics, we adopted the most commonly used method in the cosmetics industry to test and evaluate the antiseptic efficacy of cosmetics - microbial challenge test. The specific method is as follows:

Abstract

The invention discloses a bacteriostatic preservative composition and a cosmetic composition comprising same. The bacteriostatic preservative composition includes oil of eucalyptus citriodora leaves and at least one additive selected from the following components: 1,2-alkylglycol being 3-10 in carbon number, phenoxyethanol, benzyl alcohol, chlorphenesin, ethylhexyl glycerin, p-hydroxybenzoic acid and salts and esters thereof, benzoic acid and salts and esters thereof, sorbic acid and salts thereof, iodopropynyl butylcarbamate, imidazolidinyl urea and bis(hydroxymethyl)imidazolidinyl urea, polyaminopropyl biguanide, DMDM hydantoin, 2-bromo-2-nitropropane-1,3-diol, methyl isothiazolinone, methyl chloroisothiazolinone or a mixture of the components. The bacteriostatic preservative composition significantly improves mildew-proof and anti-bacterial performance.

Description

1. Technical field [0001] The present application relates to an antibacterial antiseptic composition and a cosmetic composition containing it, especially an antibacterial antiseptic composition containing oil of lemon eucalyptus and a cosmetic composition containing it. 2. Background technology [0002] Cosmetics are extremely susceptible to microbial contamination and become spoiled and unusable. Therefore, preservatives are commonly added ingredients in the cosmetics manufacturing process. Many chemical substances have antibacterial effects, but not many are used in cosmetics. According to the data provided by the US FDA and CTFA, there are about 110-120 types of preservatives used in cosmetics, including more than 40 compounds and more than 20 derivatives , about 50 kinds of compound preservatives, my country's "Hygienic Standards for Cosmetics" (2007 edition) stipulates that there are 56 kinds of preservatives restricted in cosmetic components, and the concentration of us...
