DEGRADATION OF AEROSOLS 191 Results of the test on anhydrous alcohol products do not appear to be affected significantly by moisture content in the range below 0.1%. The denaturants ot• SDA-40 also have no serious influence on the results as long as they are of good quality discolored quassin denaturant induces considerable instability.
