alpha-isomethyl ionone (80% min.)

CAS Number: 127-51-5

The statistical data we collected from 13 public perfume formulas suggests that the mean dose for alpha-isomethyl ionone (80% min.) is 4.0%. The typical lower limit is 2.0%, and the usual higher limit is 4.8%. The highest amount of alpha-isomethyl ionone (80% min.) we encountered in any single formula is 11%, and the lowest was 0.17%.
Please note that according to the IFRA Standard Category 4, the level of alpha-isomethyl ionone (80% min.) should not exceed 30% of the final product. Assuming that you will be using your formula for an alcoholic perfume at a 10% dilution, this means you should only use alpha-isomethyl ionone (80% min.) at 300% or less of the formula.
