Problems solved by technology

[0004] At present, there are not many commercially available natural preservatives that can be really applied in the cosmetics industry. The main reason is that the antiseptic effect is difficult to achieve the claimed effect, and there are many application restrictions (product dosage form, pH, compatibility, affecting odor and color, etc.), price Expensive etc.

Abstract

The invention discloses a natural antiseptic, a preparation method thereof and an application in cosmetics. The present invention treats Iridaceae red onion and thyme root by enzymatic hydrolysis, and then subcritically extracts the obtained treated substance to obtain a composite plant extract, dissolves the composite plant extract in polyol, adds antiseptic synergist, and homogenizes , Membrane filtration to obtain natural preservatives. The present invention adopts enzymatic hydrolysis and subcritical fluid extraction technology to extract the antibacterial active ingredients in Iridaceae red onion and thyme root, which overcomes the problem of low extraction rate caused by the difficulty of destroying the cell wall in traditional water extraction or alcohol extraction. High extraction rate. The natural preservative of the invention does not contain conventional chemical synthetic substances, has little skin irritation, is safe and effective, and is especially suitable for application as a preservative in cosmetics.

Description

technical field [0001] The invention relates to the field of natural preservatives, in particular to a natural preservative mainly composed of natural plant extracts, a preparation method thereof and an application in the field of cosmetics. [0002] technical background [0003] The raw materials and additives in cosmetics contain a lot of nutrients and water. In a suitable environment, microorganisms will multiply in cosmetics, resulting in corruption and deterioration of cosmetics. A certain amount of preservatives need to be added to inhibit the metabolism of bacteria, molds and yeasts and affect its growth and reproduction. Many traditionally used chemically synthesized preservatives often have certain toxicity due to their own structure and properties, such as DMDMH is a formaldehyde releaser; Kason series contains chlorine, which may be irritating to some skins; Bropol may cause cancer Formation of substances nitrosamines; IPBC may lead to iodine intake. Therefore, i...
