CAS Number: 16251-77-7
The statistical data we collected from 6 public perfume formulas suggests that the mean dose for hyacinth butanal is 0.098%. The typical lower limit is 0.071%, and the usual higher limit is 0.75%. The highest amount of hyacinth butanal we encountered in any single formula is 0.75%, and the lowest was 0.050%.
Please note that according to the IFRA Standard Category 4, the level of hyacinth butanal should not exceed 0.44% 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 hyacinth butanal at 4.4% or less of the formula.
