IFRA Restriction

This is the maximum allowed percentage of this material in the total finished product, not in the fragrance concentrate.

For example, if a fine fragrance (Category 4A) contains 20% fragrance oil, and IFRA allows 10% of this material, the material can be up to 50% of the fragrance concentrate (10% ÷ 20% = 50%).

CAS 81-15-2
