Example Embodiment

[0021] The following examples help those skilled in the art to more fully understand the present invention, but do not limit the present invention in any way. Example 1

[0022] Table 1. Feeding amount of each formula of natural plant preservative composition (% by weight)

[0023]

[0024] Preparation method: In an appropriate size three-necked bottle (such as 250mL) with stirring and thermometer, according to the feeding amount of each formula in Table 1, first add resveratrol and solvent and stir, then add synergist, heat up to 60 ℃, stir After it is completely dissolved, it can be lowered to room temperature to obtain a stable natural plant preservative composition.

Example Embodiment

[0025] Example 2

[0026] Antibacterial (antibacterial) test - determination of antibacterial inhibition ring (Oxford cup method).

[0027] Refer to "Technical Specifications for Disinfection (2002 Edition)" "Technical Specifications for Disinfection Products Inspection No. 2.1.8.2 Antimicrobial Effectiveness Testing", USP35- Antimicrobial Effectiveness Testing, "Cosmetics Hygiene Specifications (2007 Edition)" "4 Some Microbiological Test Methods".

[0028] 1. Test strains: Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Candida albicans.

[0029] 2. Test sample: the 1#-4# preservative compositions in Example 1 were used at a concentration of 2%, and 50% propylene glycol was used as a blank control.

[0030] 3. Judgment of bacteriostatic effect: If the diameter of the bacteriostatic ring is greater than 7mm, it is judged to have bacteriostatic effect. If the diameter of the antibacterial ring is less than or equal to 7mm, it is judged to have no antibacterial e...

Example Embodiment

[0033] In Table 2, the resveratrol concentration is 0.3%, which is the same as the content of resveratrol obtained by conversion with preservative composition 4#. It can be seen that the inhibition zone value of resveratrol to each bacteria, except Staphylococcus aureus Compared with Bacillus subtilis, it is better than 1#, and the rest are lower than the inhibition zone value of each preservative composition, that is, the antibacterial effect of the preservative composition is better than that of resveratrol alone. Example 3

[0034] Antibacterial (inhibitory) test - minimum inhibitory concentration (MIC value)

[0035] The minimum inhibitory concentration (MIC value) of each formula preservative composition was determined by the plate coating method, and the results are shown in Table 3.

[0036] Table 3 Determination of minimum inhibitory concentration of preservatives (MIC value)

[0037]

[0038]

[0039] The results in Table 3 show that the MIC value of each pres...

Abstract

The invention discloses a natural plant preservative composition, and particularly relates to a natural plant preservative composition comprising resveratrol, a synergist and a solvent. The natural plant preservative composition can be used for reducing the use amount of resveratrol by taking full play of the synergic antibacterial action of the synergist. The preservative composition disclosed by the invention has broad antibacterial spectrum, is easy to use, safe and effective, and has no harm to a human body. The natural plant preservative composition is used in personal care products, laundry washing products, wet wipes and other products.

Description

technical field [0001] The invention relates to a preservative composition, in particular to a plant preservative composition composed of resveratrol, a synergist and a solvent. Background technique [0002] Most of the current preservatives are synthetic chemicals, which usually have certain toxic side effects and may cause (potential) harm to the human body. For example, the commonly used chemical preservative 1,3-dimethylol-5,5-dimethylhydantoin will worry about the release of formaldehyde; the isothiazolinone series may cause some skin types Irritation allergy; Bropol may lead to the formation of carcinogen nitrosamines; iodopropynyl butyl carbamate (often referred to as IPBC) will increase the possibility of iodine intake; the most commonly used parabens It has been exposed to have the effect of simulating estrogen and so on. While some of the reports turned out to be exaggerated, they actually reflected the reality of concerns about chemical preservatives. With the ...
