Process for testing diffusivity, odor character and odor intensity of a fragrance material and fragrance diffusion evaluation apparatus for carrying out such process

摘要

Described is a fragrance diffusion evaluation apparatus for testing the diffusivity, odor character and odor intensity of a fragrance material and a process for using same. The apparatus includes one or two hollow cylinders, each having a test sample suspended therein, devices for passing air through the inside of each of the cylinders and exit ports in each of the cylinders for the air flow where the intensity and aroma character are measured as a function of time and as a function of temperature. The sample is weighed initially and at time intervals, while the air is flowing through each of the cylinders at a fixed or variable rate.
