Abstract

The invention provides a plant bacteriostatic composition and application thereof in cosmetics. The plant bacteriostatic composition is obtained by compounding a licorice extract, a honeysuckle extract and a Mangnolia officinalis extract. The plant bacteriostatic composition has good bacteriostatic effect and particularly has a synergistic effect of inhibiting escherichia coli, staphylococcus aureus, pseudomonas aeruginosa, candida albicans and aspergillus niger. The plant bacteriostatic composition can be applied to skin-care and washing cosmetics, reduces the adding amount of original preservatives and enables a product to have both antibacterial and anti-inflammatory effects.

Description

technical field [0001] The invention relates to a plant antibacterial composition, in particular to a plant antibacterial composition which is added to cosmetics and has antibacterial effect, and belongs to the field of cosmetic additives. Background technique [0002] During the storage and use of cosmetics, they are extremely susceptible to microbial contamination and cause corruption. Due to the action of microorganisms, cosmetics can deteriorate and spoil, and their color and smell will change in the senses, thus losing their commodity value. More importantly, the pollution of pathogenic microorganisms can cause harm to human health. The most effective way to prevent cosmetics from harming human skin and product deterioration and mold due to microbial contamination is to add preservatives. Preservatives are a class of chemical agents that can inhibit the growth and reproduction of microorganisms. [0003] Commonly used preservatives in traditional cosmetics are paraben...
