Problems solved by technology

[0003] Preservatives can inhibit or prevent the growth and reproduction of microorganisms, but they are also common factors that cause allergic reactions and other irritating reactions to cosmetics. Traditional preservatives have a certain risk of carcinogenicity due to the presence of formaldehyde or formaldehyde release bodies; or contain organic halogen components , has a strong irritant, has a high sensitization rate to the skin, and is harmful to the human body. A study by the European Union shows that parabens can cause endocrine disorders in the human body, affect development and produce reproductive toxicity, and have adverse effects on the brain, nervous system and behavior. mode will affect
Therefore, more and more people pay attention to the safety of preservatives. In addition, 50% of the people with sensitive skin now pay more attention to the types of preservatives in cosmetics when choosing skin care products. There are very few types of non-irritating preservatives, and it is difficult for cosmetic engineers to choose a satisfactory type in product development
Although some Chinese herbal medicines have certain antibacterial properties by themselves or after extraction, their ability to kill microorganisms is relatively weak, and they usually need to be used in combination with traditional preservatives. Therefore, there is an urgent need for a safe and mild antiseptic. Bacteriostatic natural preservative

Abstract

The invention discloses a natural preservative, the main component of the natural preservative is a plant fermentation liquid, the plant fermentation liquid is prepared by fermenting hypericum monogynum, dandelion and honeysuckle, and the bacteriostatic ability of the plant fermentation liquid is superior to that of an unfermented plant extract; another purpose of the invention is to provide a more stable natural preservative, the natural preservative comprises 1-8 parts of lavender essential oil, 5-15 parts of polyol, 1-5 parts of paeonol and 55-80 parts of plant fermentation broth, the stability is high, the natural preservative is used in cosmetics, the preservative ability is excellent, and the shelf life of the cosmetics can be prolonged.

Description

technical field [0001] The invention relates to the technical field of cosmetics, in particular to a natural preservative and its application in the preparation of cosmetics. Background technique [0002] In recent years, with the rapid development of the cosmetics industry, people are increasingly pursuing the versatility and safety of cosmetics. In order to achieve more functions, rich nutrients are usually added, which provides a basis for the growth and reproduction of microorganisms. Microorganisms can not only cause changes in the smell, color and viscosity of cosmetics, but also lead to the degradation of the active components of the product, changes in the sense of use, and even harm to human health. In the prior art, preservatives are usually added to ensure that cosmetics do not deteriorate during the shelf life. [0003] Preservatives can inhibit or prevent the growth and reproduction of microorganisms, but it is also a common factor that causes allergic reaction...
