Nano-microcapsule with blumea balsamifera essential oil as well as preparation method and application of nano-microcapsule

Abstract

The invention discloses a nano-microcapsule with blumea balsamifera essential oil. The nano-microcapsule comprises a core material and a wall material, wherein the core material is blumea balsamifera essential oil, the wall material is formed by carrying out cross-linked reaction between sulfhydryl modified chitosan and a cross-linking agent, and the wall material is coated with the core material. The invention also discloses a preparation method of the nano-microcapsule with the blumea balsamifera essential oil, i.e., the blumea balsamifera nano-microcapsule is prepared by adopting a controlled release technology of the nano-microcapsule and a nano-directional skin permeability absorption technology. The problems that active ingredients of the blumea balsamifera essential oil are unstable and efficacy action time of the blumea balsamifera essential oil is short are solved; the bioavailability of the blumea balsamifera essential oil is improved and an application range of the blumea balsamifera essential oil is widened; moreover, the nano-microcapsule has the advantages of non-toxicity, security, low cost and easiness for realization of industrial production and the like, so that the nano-microcapsule has wide application values in drugs, cosmetics, skin care products and spice and flavor additives.

Description

technical field [0001] The invention relates to the technical field of microcapsule preparation, in particular to the nano-microcapsules of Aina essential oil, the preparation method and application of the nano-microcapsules of Aina essential oil. Background technique [0002] Ainaxiang is one of the important ethnic medicines in my country. It has a long history of medication in Li, Zhuang, Miao and other minority areas.

The Chinese invention patent with the publication number CN102851120A discloses a method for extracting Aina sesame oil, in which a yellow oily liquid Aina sesame oil, ie Aina fragrance essential oil, is obtained by extracting and separating the Aina fragrance raw material. The Chinese invention patent with the publication number CN106214716A discloses a kind of oral tablet containing Ainax...

AI Technical Summary

Problems solved by technology

[0003] However, Aina essential oil is highly volatile, and its active ingredients are easy to volatilize and lose, and are easily affected by environmental factors such as light and heat. It has poor thermal stability and is not easy to process, use and store.

In addition, when Aina essential oil is directly applied to cosmetics, the absorption effect of human skin is poor, and the time of adding fragrance is short, so the effect is not ideal

These defects cause the application effect and scope of application of Aina essential oil to be greatly limited

[0004] At present, research on improving the photothermal stability of Aina essential oil and prolonging its efficacy and action time is still relatively lacking, which makes the utilization of Aina essential oil not high, and it is difficult to meet the needs of the practical application of Aina essential oil, nor can it fully reflect The Economic Value of Aina Essential Oil
