Problems solved by technology

Although the preservatives of natural plant extracts generally have certain safety, their antibacterial effect cannot reach the performance of chemical preservatives, especially the effect of inhibiting fungi and mold is not good.
For example, it is disclosed in the prior art that hibiscus flower extract has a high inhibitory rate to bacteria but a low inhibitory rate to mold, and Magnolia extract has a high inhibitory rate to mold but a low inhibitory rate to bacteria

Embodiment 1

[0015] A natural plant extract composition, which is formed by mixing hibiscus flower extract and magnolia extract with a mass ratio of 1:3;

[0016] The preparation method of the hibiscus flower extract is as follows: soak the freshly picked hibiscus flower with 50v / v% ethanol aqueous solution of 5 times the mass for 1h, and extract it with a high-pressure homogeneous extractor at room temperature, the extraction pressure is 100MPa, and the extraction time is 30min ; After centrifugation, the extract is adsorbed with AB-8 macroporous resin, eluted with 95v / v% ethanol aqueous solution, and the eluate is evaporated to dryness to obtain the final product;

[0017] The preparation method of the extract of Tiannv Magnolia is as follows: the freshly picked Tiannv Magnolia leaves are refluxed and extracted with 3 times the mass of 80v / v% ethanol aqueous solution for 2 hours, the extract is filtered, the filtrate is concentrated into an extract after recovering ethanol, dissolved in w...

Abstract

The invention discloses a natural plant extract composition. The natural plant extract composition is prepared by mixing a hibiscus mutabilis extract and a magnolia sieboldii extract in a mass ratio of 1: (1-5). The natural plant extract composition is used as a cosmetic preservative, the hibiscus mutabilis extract and the magnolia sieboldii extract which are obtained by adopting a specific preparation method generate a synergistic effect in the aspect of preservative and bactericidal effects, and the technical effect unexpected by technicians in the field is achieved. According to the naturalplant extract composition, raw material components from natural plants are adopted to replace traditional preservatives, the possibility that the traditional preservatives causes skin irritation is avoided while preservative and antibacterial effects are provided for cosmetic products, and therefore the allergy rate of the products is greatly reduced.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a natural plant extract composition and its application in cosmetics. Background technique [0002] With the advancement of science and technology and the improvement of living standards, people pay more and more attention to skin care and the safety of skin care products, especially the demand for cosmetic products is becoming more and more natural and nutritious, but the existing cosmetics More nutrients such as protein, vitamins, soluble collagen, oil, wax and other plant extracts are often added. Cosmetics contain such rich nutrients that they are especially suitable for the growth of microorganisms, so preservatives need to be added to cosmetics. The purpose of adding preservatives to cosmetics is to inhibit the growth and production of microorganisms, avoid deterioration of cosmetics and maintain freshness and persistence. [0003] At present, most skin care products in the prior...
