CAS Number: 144020-22-4
The statistical data we collected from 5 public perfume formulas suggests that the mean dose for amber decatriene is 0.50%. The typical lower limit is 0.25%, and the usual higher limit is 0.80%. The highest amount of amber decatriene we encountered in any single formula is 0.80%, and the lowest was 0.15%.
Please note that according to the IFRA Standard Category 4, the level of amber decatriene should not exceed 2.4% 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 amber decatriene at 24% or less of the formula.
