Problems solved by technology

Third, the substances extracted from natural plants are not necessarily safe. For example, the cinnamon extract contains a relatively high content of cinnamaldehyde, which has a good bactericidal effect, but at the same time, it will cause skin irritation at very low levels. irritation, even skin ulceration
Fourth, the functional ingredients contained in various plants are affected by factors such as seasonal harvest time, which brings greater difficulty to practical application
Fifth, the functional ingredients in natural extracts generally have a narrow antibacterial spectrum. For example, lactic acid bacteria extracted from lactic acid bacteria fermentation can only inhibit or kill Gram-positive bacteria, such as Staphylococcus, but are not effective against Gram-negative bacteria. , such as Pseudomonas aeruginosa and Escherichia coli, fungi, Candida albicans and Aspergillus niger have no effect

Abstract

The invention relates to a natural cosmetic preservative composition and a preparation method thereof. The natural cosmetic preservative composition is prepared from the following raw materials according to a proper weight proportional ratio, wherein the raw materials comprise three natural components of lactic acid bacteria fermentation extract, rice bran extract and peony root bark extract; thecomponents of the raw materials reach the synergistic function. The natural cosmetic preservative composition has the advantages that the preparation method of the preservative composition is optimized; the mixing of the components of the raw materials is specifically treated, so that the anticorrosive ability of the preservative composition and the stability in the cosmetics are improved; the finally prepared preservative composition has good cosmetic anticorrosive function; proofed by experiment, the preservative composition can pass through the anticorrosive challenge test, and the safe andnon-irritation effects are realized for skin.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a natural cosmetic preservative composition and a preparation method thereof. Background technique [0002] Cosmetics contain more nutrients that are conducive to the growth of microorganisms, such as sugars and proteins. Although good environmental control during production can ensure that products are sterile, exposure to air and skin-derived microorganisms is unavoidable during consumer use. If the growth of microorganisms cannot be controlled, on the one hand, it will change the appearance and smell of the product, on the other hand, the secondary metabolites of pathogenic microorganisms will also cause various human hazards. [0003] Pathogenic microorganisms commonly found in cosmetics include Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Aspergillus niger, and Candida albicans. In cosmetics, the growth of microorganisms is usually inhibit...
