A kind of preparation method of deodorant type long-acting slow-release solid plant essential oil

Abstract

The invention discloses a preparation method of deodorizing long-acting slow-release solid plant essential oil. Firstly, the halloysite nanotube is activated, and then formed on the surface of the activated halloysite nanotube through the polymerization reaction of cyclodextrin and isocyanate network structure, and then the essential oils are loaded into the nanotubes by impregnation. Using the nanoscale cavities in halloysite nanotubes to increase the loading capacity of plant essential oils and reduce the release rate of plant essential oils; using cyclodextrin molecular holes to form complexes with essential oil molecules at the ports of halloysite nanotubes, further Control the release of essential oils to achieve long-term sustained release of essential oils; the molecular cavities of cyclodextrin polymers can also include and absorb odor molecules, thereby deodorizing. The service life of the essential oil in the product is greatly extended, and the product strength is obviously improved. The invention has reasonable design, integrates deodorization and slow release of essential oil, and has strong practicability.

Description

technical field

[0001] The invention relates to a preparation method of solid plant essential oil, in particular to a preparation method of deodorizing long-acting slow-release solid plant essential oil. Background technique

[0002] Natural plant essential oil is a natural antibacterial agent with high efficiency, non-toxicity, high selectivity and resistance to drug resistance. However, natural plant essential oil is extremely volatile at room temperature, and is sensitive to air, sunlight, humidity and temperature. Sensitive, easily decomposed or oxidized during storage, resulting in deterioration of aroma. At present, the application of microencapsulation technology can change the essential oil from liquid to solid powder, protect the aroma substances from being directly affected by heat, light, and oxidation, avoid the volatilization of active ingredients, and effectively control the release of aroma substances. However, the main shortcomings of the current application...
