Abstract

The invention discloses a mixed natural antibacterial agent. The mixed natural antibacterial agent comprises, by weight percentage, 5-50% of ampelopsin grossedentata extract, 5-70% of one or more natural fragrant materials, and 1-80% of mixed solution of propylene glycol and water. The invention further provides a preparation method of the mixed natural antibacterial agent. The preparation method includes: weighing the ampelopsin grossedentata extract, the natural fragrant materials and the mixed solution of propylene glycol and water according to the weight percentage, and heating to dissolve the ampelopsin grossedentata extract in propylene glycol aqueous solution; adding the natural fragrant materials into the solution, and well mixing to obtain the mixed natural antibacterial agent. The invention further provides cosmetics containing the mixed natural antibacterial agent. The mixed natural antibacterial agent can effectively inhibit the microorganism reproduction in the cosmetics and can replace chemically-synthesized preservatives, and accordingly product irritation is lowered and product safety is increased.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a cosmetic additive, in particular to a compound natural antibacterial agent, a preparation method thereof and an application in cosmetics. Background technique [0002] With the improvement of living standards, cosmetics, as an important part of the "beauty economy", are also developing rapidly and become an indispensable part of people's daily life. According to investigations, cosmetics have been used for nearly 50,000 years. Especially in the past 40 years, the cosmetics industry in various countries in the world has developed rapidly. People use cosmetics more and more commonly, and they pay more and more attention to the safety of cosmetics. Most cosmetics are rich in the nutrients needed for the growth of microorganisms. Once the microorganisms in the environment enter, they can multiply rapidly, destroying the sensory quality of the product and harming the health of consum...
