Litsea cubeba oil mildew and moth proof slow release microcapsule and preparation method

Abstract

The invention provides a litsea cubeba oil mildew and moth proof slow release microcapsule and a preparation method. The Litsea cubeba oil mildew and moth proof slow release microcapsule comprises a wall material and the wall material-coated litsea cubeba oil, the wall material is prepared by employing ethyl cellulose, high-substitution hydroxypropyl cellulose, Arabic gum and maltodextrin. The preparation method comprises the following steps: dissolving ethyl cellulose by N-methyl-2-pyrrolidone to obtain ethyl cellulose viscous fluid; taking high-substitution hydroxypropyl cellulose, Arabic gum and maltodextrin and mixing by water to completely dissolve, adding the prepared ethyl cellulose viscous fluid, then adding the litsea cubeba oil under stirring, dispersing with high speed, homogenizing, spraying and drying to obtain the products. According to the invention, the screened wall material enables penetration and diffusion on the litsea cubeba oil, and enables optimization of the microcapsule preparation technology; the screened wall material can be prepared to the solid state microcapsule mildew and moth proof product with characteristics of green health, high efficiency and notoxicity, convenient usage and slow release property.

Description

technical field

[0001] The invention relates to a daily anti-mildew and anti-moth agent, in particular to an anti-mold and anti-moth slow-release microcapsule of litsea cubeba oil and a preparation method thereof. Background technique

[0002] Anti-mildew and anti-moth agents are widely used daily consumer goods in our country, especially in the rainy season in the Jiangnan area. The vast majority of such products currently on the market are "camphor balls" with p-dichlorobenzene as the main component, and there are very few anti-mold and moth-proof agents with natural camphor (camphor) as the main component. P-dichlorobenzene is a derivative of aromatic compounds obtained by fractional distillation of petroleum or coal tar. Studies since the late 1940s have shown that it has definite toxic effects on the human body. Prolonged exposure can cause symptoms such as dizziness and vomiting , Excessive use can cause liver and lung damage, acute hemolytic anemia, large doses of ca...
