Abstract

The invention provides a slow-release agarwood microcapsule, and a preparation method and application thereof, and relates to the field of washing. The slow-release agarwood microcapsule comprises agarwood oil, n-heptane, emulsifiers, polyvinyl alcohol, inorganic acid, pentanediol, pH regulators and water. The slow-release agarwood microcapsule has the advantages of capabilities of keeping fragrance for a long time, repelling insects and preventing moths.

Description

technical field [0001] The invention relates to the field of washing, in particular to an agarwood slow-release microcapsule and its preparation method and application. Background technique [0002] The traditional laundry washing process pays more attention to basic functions such as cleaning, suppleness and anti-static, but with the development of the times, people have more diversified functional requirements for laundry detergents, and pay more attention to the fragrance retention, anti-moth, antibacterial, etc. Features. However, products with these high-level functions are relatively scarce in the market and cannot meet the needs of the masses. Contents of the invention [0003] Based on this, it is necessary to provide a kind of slow-release microcapsules of agarwood to solve the technical problem that the fragrance of existing washing products is not long enough after washing clothes. [0004] A kind of agarwood sustained-release microcapsules, comprising the fol...
