The statistical data we collected from 48 public perfume formulas suggests that the mean dose for beta-naphthyl methyl ketone is 0.32%. The typical lower limit is 0.23%, and the usual higher limit is 1.5%. The highest amount of beta-naphthyl methyl ketone we encountered in any single formula is 4.0%, and the lowest was 0.012%.
Please note that according to the IFRA Standard Category 4, the level of beta-naphthyl methyl ketone should not exceed 0.20% 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 beta-naphthyl methyl ketone at 2.0% or less of the formula.
