How is the allergen concentration calculated when it comes from a fragrance blend?

The concentration threshold applies to the allergen in the finished product. When the allergen is contributed by a fragrance blend, the allergen content of the blend must be multiplied by the percentage of blend used in the formula. If the result exceeds the threshold, the allergen must be declared on the label.

Declaration of BENZYL CINNAMATE is mandatory when the concentration exceeds 0.001% (10 ppm) in leave-on cosmetic products or 0.01% (100 ppm) in rinse-off products. Below these thresholds, label declaration is not required but may be made voluntarily.

The concentration threshold applies to the allergen in the finished product. When the allergen is contributed by a fragrance blend, the allergen content of the blend (provided by the fragrance supplier) must be multiplied by the percentage of blend used in the formula. If the calculated total allergen concentration exceeds the threshold, it must be declared on the label.
