Preparation of natural plant preservative compound and application of natural plant preservative compound to cosmetics

Abstract

The invention provides a plant preservative compound. The compound comprises impatens commllinoides, forsythia suspensa, prinsepia utilis, magnolia liliiflora and polygonum cuspidatum. The plant preservative compound is prepared through steps of performing soaking and extraction on raw materials with an enzyme solvent and a water-alcohol mixed solvent for 3-22 hours, performing filtration, performing reflow heating, concentrating components of a plant extracting solution, and preparing a natural plant preservative which is used for replacing a traditional chemical synthesis preservative and used for the technical field of antisepsis of industrial cosmetics. Compared with other preservatives, the plant preservative compound disclosed by the invention has the advantages that the components in the plant preservative compound disclosed by the invention, including the impatens commllinoides, the prinsepia utilis and the magnolia liliiflora, are specific medicinal plants in China, so that the plant preservative compound has medical value when being used for cosmetics. The plant preservative compound has restraining and destroying effects on staphylococcus aureus, escherichia coli, candida albicans and the like, which are common in the cosmetics, ingredients all come from nature, and the plant preservative compound has the characteristics of being free from irritants, free from toxicand side effects, wide in antimicrobial spectrum, efficient and the like.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to the preparation of a natural plant preservative compound and its application in cosmetics. Background technique [0002] Most cosmetics are usually rich in protein, amino acids and other nutrients necessary for the reproduction of microorganisms. Therefore, anti-corrosion is a very important link in the quality control of cosmetics production. In order to achieve the purpose of anti-corrosion and prolong the shelf life, adding preservatives is common. adopted and effective methods. There are 51 kinds of preservatives approved in my country's "Safety and Technical Specifications for Cosmetics" (2015 Edition), all of which are chemically synthesized substances. Chemically synthesized preservatives have the defects of high irritation and toxicity, and are not very safe in terms of safety. Satisfactory, such as quaternary ammonium salts, parabens, oxazolidine compounds,...

Problems solved by technology

Patent (publication number: CN 105902445A) a plant preservative composition used in cosmetics and its preparation method. Although the composition also passed the antiseptic challenge test, it is not clear about the stability of the composition

It can be seen that the applied plants in the existing patents all have the problem of narrow antibacterial spectrum. In addition, plant extracts contain more active substances, and their stability is poor, and the shelf life is short, which is also a problem in this field.
