Abstract

The invention provides a cosmetic containing a plant bacteriostatic composition, containing 0.2-2.0% by weight of plant bacteriostatic composition; the plant bacteriostatic composition is formed by a licorice extract, a honeysuckle extract and a magnolia bark extract through compound combination. The cosmetic provided by the invention has good bacteriostatic action, particularly having synergistic effect on a side of inhibiting escherichia coli, staphylococcus aureus, pseudomonas aeruginosa, candida albicans and aspergillus niger so as to reduce additive amount of former chemical preservatives, and enable products to have antibacterial and anti-inflammatory effects at the same time.

Description

technical field [0001] The present invention relates to a cosmetic, in particular to a cosmetic containing a plant antibacterial composition composed of licorice extract, honeysuckle extract and magnolia bark extract. The cosmetic has good antibacterial effect, Can reduce the addition of chemical preservatives. 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. ...
