Work out fragrance load instantly with clear inputs, formula shown and shareable results.
Fragrance load is a percentage of the batch. Typical levels are 0.3-1.5% for leave-on skin products, 0.5-2% for rinse-off, 6-10% for candles and 10-25% for fine fragrance. IFRA sets category-specific limits for individual restricted materials, so the permitted load depends on the fragrance composition and the product type.
Fragrance quantity
Fragrance (g) = batch size x load % / 100
Fragrance use levels are restricted by IFRA standards and allergen declaration is required by cosmetic regulation. Obtain an IFRA certificate for each fragrance and product category.
Because exposure differs. A leave-on face cream leaves material on skin all day, while a rinse-off shower gel is largely washed away, so the permitted concentration is much higher for the latter.
No. Those are declaration requirements above 0.001% in leave-on and 0.01% in rinse-off products, separate from IFRA use limits. Both must be checked.
