CAS Number: 68917-40-8
The statistical data we collected from 4 public perfume formulas suggests that the mean dose for treemoss concrete is 2.3%. The typical lower limit is 1.3%, and the usual higher limit is 2.8%. The highest amount of treemoss concrete we encountered in any single formula is 3.0%, and the lowest was 0.50%.
Please note that according to the IFRA Standard Category 4, the level of treemoss concrete should not exceed 0.10% 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 treemoss concrete at 1.0% or less of the formula.
