AI Technical Summary

Technical Problem

Existing natural fragrance solids have short fragrance duration, slow fragrance release, and poor release rate and stability, which limits their widespread use in daily applications.

Method used

A triple controlled-release structure was constructed using modified attapulgite, biochar, and modified starch. The pore volume and surface area were increased by thermal modification and acid dredging treatment of the modified attapulgite. Combined with the hydrophilic and lipophilic interfacial membrane of the modified starch and the three-dimensional network of the hygroscopic agent, a stable aroma release system was formed.

Benefits of technology

It achieves long-lasting and stable release of fragrance, ensuring uniform and stable release of fragrance, adapting to different climatic conditions and usage scenarios, and avoiding excessively rapid evaporation of fragrance and uneven release caused by humidity fluctuations.

Abstract

The application relates to the chemical technology field, in particular to a natural fragrance solid fragrance and a preparation method thereof, which are used to solve the problems that the existing fragrance has a short fragrance duration, is greatly affected by temperature, and has relatively weak fragrance release rate and stability; the natural fragrance solid fragrance has good durability, a modified attapulgite / biochar composite slow-release agent, modified starch and a triple controlled-release structure of wax base are constructed, rapid volatilization of fragrance can be effectively avoided, linear and stable release is realized, the fragrance duration is relatively long, the adsorption rate difference of the slow-release agent for components of essential oil is small, and the hygroscopic agent can slightly adjust the local environment, so that the top note, body note and base note of the fragrance can be evenly released, and the fragrance type is kept consistent; the plant glycerol, the hygroscopic agent and other easily-migrated components are pre-combined with powder materials, so that the surface is dry, the structure is complete, oil penetration and cracking are not easy in long-term use or high-temperature environment.
