The propellent and the synergist in insecitcidal aerosols are collected separately and their identifications have been attempeted by use of the infrared absorption spectrum method. For the measurement of the spectra, the propellent is placed in a gas cell having the length of 10 cm, and the synergist is estimated by placing it between two NaCl plates with a lead spacer of the thickness of 0.03mm, and the results are confirmed by comparing them with the IR absorption spectrum of each standard substance. This method has a merit of rapid estimation of all constituents with the use of a small amount of sample wihthout breaking the aerosol container. The results of estimation of 11 kinds of commercial samples indicated that 4 kinds of them showed difference in composition from those indicated on their labers.
