Fragrance Load Calculator

Work out fragrance load instantly with clear inputs, formula shown and shareable results.

About Fragrance Load Calculator

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.

Formula

Fragrance quantity

Fragrance (g) = batch size x load % / 100

Worked example

With the default values below, Fragrance Load Calculator returns Fragrance Required of 10.0000. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax or compounding frequency into account.
  • Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • 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.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why do IFRA limits differ by product?

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.

Are the 26 allergens the same thing?

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.
