Problems solved by technology

[0004] Although the existing natural plant preservatives have many advantages, there may still be problems such as certain extract solvent residues or a large amount of addition, and they often cannot completely replace chemical preservatives, and generally can only be used as their supplement or synergistic enhancement. active ingredient use

Embodiment 1

[0022] Table 1. Natural plant preservative composition each formula feeding amount (weight %)

[0023]

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

Embodiment 2

[0026] Anti-(inhibition) bacteria test - Determination of antibacterial ring of preservatives (Oxford cup method).

[0027] Refer to "Technical Specifications for Disinfection Products (2002 Edition)" in "Technical Specifications for Disinfection Products Inspection No. 2.1.8.2 Bacteriostatic Ring Test", USP35-Antimicrobial Effectiveness Testing, "Hygienic Specifications for Cosmetics (2007 Edition)" "4th Some microbiological test methods".

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

[0029] 2. Test sample: 1#-4# preservative composition in embodiment 1, use concentration is 2%, with 50% propylene glycol as blank control.

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

Embodiment 3

[0034] Anti-bacterial (inhibition) test - minimum inhibitory concentration (MIC value)

[0035] The minimum inhibitory concentration (MIC value) of each formula preservative composition was determined by the flat 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 preservative composition is lower than that of a single resveratrol, indicating that the antibacterial effect of the preservative composition is better than that of resveratrol alone, and can reduce the amount of resveratrol used.

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 ...
