(E)-alpha-methyl ionone (74-80%)
CAS Number: 127-42-4
The statistical data we collected from 5 public perfume formulas suggests that the mean dose for (E)-alpha-methyl ionone (74-80%) is 5.0%. The typical lower limit is 0.90%, and the usual higher limit is 15%. The highest amount of (E)-alpha-methyl ionone (74-80%) we encountered in any single formula is 15%, and the lowest was 0.20%.
Please note that according to the IFRA Standard Category 4, the level of (E)-alpha-methyl ionone (74-80%) 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 (E)-alpha-methyl ionone (74-80%) at 300% or less of the formula.
