Aroma Ingredient Usage Statistics
CAS Number: 106-02-5
The statistical data we collected from 83 public perfume formulas suggests that the mean dose for omega-pentadecalactone is 1.5%. The typical lower limit is 0.76%, and the usual higher limit is 3.2%. The highest amount of omega-pentadecalactone we encountered in any single formula is 20%, and the lowest was 0.020%.
Please note that according to the IFRA Standard Category 4, the level of omega-pentadecalactone 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 omega-pentadecalactone at 24% or less of the formula.
