| introduction | the relative density of artemisia artemisia oil is 0.914, refractive index is 1.470, dissolution rate is 2.8, and optical rotation is 4.6. Artemisia artemisia oil has an inhibitory effect on cocci, gram-negative bacilli and a variety of fungi. It was first used to prepare perfume, cosmetics and pharmaceutical raw materials. |
| efficacy | clinical and animal experiments have proved that the volatile oil, the main component of Artemisia argyi oil, has obvious flat-end, antitussive, expectorant and anti-inflammatory effects, but due to the unstable volatilization of its main components, the direct application efficacy is not ideal. The preparation of microcapsules by coating artemisia artemisinin oil with high molecular substances by complex coagulation method can not only maintain the original performance and biological activity of artemisinin oil to the maximum extent, but also facilitate processing, storage and transportation, improve the efficacy and expand the scope of use. In addition, its application to textile finishing can make the finished fabric obtain antibacterial health care function. |
| emulsification | the key to microencapsulation of artemisia artemisia oil is the emulsification of artemisia artemisia oil. Artemisia artemisinin oil is numerous and complex, and it is difficult to dissolve in water. It cannot be well dispersed in aqueous solution by general methods. It can only emulsify a large and single oil phase into a large number of small small droplets through the action of surfactants. Because the surface protective film formed by the emulsifier has a certain interfacial tension, it will inhibit the further division or adhesion of the artemisia oil, so that the artemisia oil droplets become a discontinuous phase and are stably dispersed in the solution. When the continuous phase chitosan and the anionic surfactant are electrostatically combined and precipitated, they just fall around the artemisia oil to form microcapsules, which can improve the utilization performance of the artemisia oil, expand the application range, and improve durability. If the artemisia oil is not emulsified, it exists in the form of oil droplets in the aqueous solution, and it is assembled into flakes between each other, and it is unstable and cannot be covered. Therefore, the emulsification of artemisia oil can be used to prepare microcapsules. The particle size, shape, distribution uniformity, stability of microcapsules and their slow-release performance play a vital role. |
| production method | essential oil is obtained by steam distillation of wormgiven leaves and flowers. Due to different varieties, it is generally 0.3% ~ 0.5% (referring to the whole grass). |
