一种微囊型空气清新剂的制备工艺研究

Study on the prearation technology of microcapsule air freshener

以丁香、薄荷精油和陈皮浸膏为主成分制备了一种微囊型空气清新剂.以留香时间和包封率为评价指标,并用正交试验筛选出了该清新剂的最优制备工艺条件:无水乙醇加入量为5 mL、水浴温度为40℃、精油(浸膏)的加入量为12 mL.经检测,本文制备的试样包封率为48.62%,留香时间为40 min(显著优于未用微囊技术生产的市售喷雾剂型空气清新剂的留香时间(25 min)).因此,本文制备的中药型微囊空气清新剂及其制备方法具有良好的推广利用价值.

A kind of microencapsule air freshener was prepared with Eugenia caryophllata Thunb,Pericarpium citri Reticulatae essential oil and Mentha haplocalyx Briq peel extractas the main components.The retention time and entrapment efficiency were used as evaluation indexes.The optimal preparation conditions of the freshener,i.e.,the amount of anhydrous ethanol(5 mL),the water bath temperature(40℃),the added amount of essential oil(extract)(12 mL)are selected by the orthogonal test.After testing,the entrapment efficiency of the microencapsule air freshener is 48.62%,and the retention time is 40 min,which is significantly greater than the retention time(25 min)of commercially air freshener produced without microcapsule technology.Therefore,the traditional Chinese medicine microcapsule air freshener and its preparation method exhibit good application value.
