Abstract

The invention provides a composite slowly-released essence microcapsule. The composite slowly-released essence microcapsule is prepared through 0.5-55wt% of essence, 0.5-30% of composite slowly-released essence microcapsule, 0.5-30% of glyceride, 0.5-20% of modified starch, 0.05-5% of emulsifying agent, 0.05-5% of mechanical resisting agent, and the balance deionized water. The invention also provides a preparation method of the abovementioned composite slowly-released essence microcapsule. The prepared composite slowly-released essence microcapsule is safe, nontoxic and biodegradable; the particle size is about 10-100 microns; the packing rate is up to 60-80%; the drug loading capacity is 30-50%; and moreover, the composite slowly-released essence microcapsule is superior to common polymer microcapsules by safety, environmental protection, and other parts; and the composite slowly-released essence microcapsule is applicable to personal nursing materials.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a microcapsule, in particular to a compound sustained-release essence microcapsule and a preparation method thereof. Background technique [0002] With the improvement of living standards in modern society, people's demand for fragrance is constantly increasing. The main flavoring method in daily chemical products is to add essence, which can increase the pleasure of daily chemical products in use, cover the smell of the raw materials themselves, and endow the product with a characteristic aroma. The production and application of flavors in foreign countries has a history of decades, while the research on flavors in our country has just emerged. Due to the relatively late start of flavor research, there is still a certain gap between my country and the international advanced level in the preparation, quality, stability, and safety of flavor products. [0003] Due to the shortcomin...
