CAS Number: 3658-77-3
The statistical data we collected from 24 public perfume formulas suggests that the mean dose for strawberry furanone is 0.51%. The typical lower limit is 0.087%, and the usual higher limit is 2.0%. The highest amount of strawberry furanone we encountered in any single formula is 10%, and the lowest was 0.0020%.
Please note that according to the IFRA Standard Category 4, the level of strawberry furanone should not exceed 0.25% 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 strawberry furanone at 2.5% or less of the formula.
