CAS Number: 57378-68-4
The statistical data we collected from 35 public perfume formulas suggests that the mean dose for delta-damascone is 0.15%. The typical lower limit is 0.050%, and the usual higher limit is 0.44%. The highest amount of delta-damascone we encountered in any single formula is 1.8%, and the lowest was 0.0070%.
Please note that according to the IFRA Standard Category 4, the level of delta-damascone should not exceed 0.043% 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 delta-damascone at 0.43% or less of the formula.
