Abstract

The invention discloses a plant composition with a bacteriostatic effect. The bacteriostatic plant composition contains a scutellaria root extract, a notoginseng root extract, a black soya bean skin extract, a honeysuckle flower extract, an anthemis tinctoria extract and a tea leaf extract. The bacteriostatic composition prepared from the natural plant extracts is high in safety, free of toxic andside effects, small in skin irritation and stable in property, and the process of adding the composition to cosmetics is simple. The bacteriostatic plant composition has the good inhibition capability on staphylococcus aureus, also has the inhibition effect on escherichia coli and pseudomonas aeruginosa, also has certain inhibition effect on candida albicans and has a good application prospect inantiseptic treatment of cosmetics.

Description

technical field [0001] The invention belongs to the field of plant application and cosmetics, in particular to a plant composition with antibacterial effect. Background technique [0002] Microbial pollution is a major cause of cosmetic product deterioration. Because cosmetic raw materials and additives contain a lot of nutrients and water, microorganisms will multiply under suitable conditions, resulting in cosmetic spoilage. Deteriorated cosmetics not only deteriorate in efficacy, but also bring harm to the health of users, such as skin allergies, infections, etc., and even cause sepsis in severe cases. Common contaminating bacteria in cosmetics include thermotolerant coliforms, Pseudomonas aeruginosa, Staphylococcus aureus and pathogenic fungi such as Aspergillus niger and Candida albicans. The "Safety and Technical Specifications for Cosmetics" (2015) set strict limits on the detection amount of common microorganisms. [0003] Generally speaking, the use of correspondi...
