IFRA basics
Understanding IFRA-style limits
This page is an independent educational overview. It is not legal advice and does not replace your supplier, certifier, or regulator.
What "IFRA" refers to
IFRA stands for the International Fragrance Association. IFRA standards are widely referenced across the fragrance industry. Many suppliers publish IFRA certificates or statements that communicate recommended maximum usage levels for a fragrance material across different product categories (for example, candles vs. leave-on lotions).
Those documents help teams align on the same vocabulary when discussing how much fragrance can be used in a given product type—subject to supplier interpretation, updates over time, and your local regulatory context.
Sunday Maker is not affiliated with IFRA
Sunday Maker is an independent educational and tooling platform for makers. We are not affiliated with IFRA, endorsed by IFRA, certified by IFRA, or officially connected to IFRA.
We reference supplier-provided IFRA documentation because IFRA-style category limits are a commonly used industry framework for communicating product-category usage guidance—not because Sunday Maker issues IFRA compliance decisions.
How Sunday Maker uses IFRA-related data
- When suppliers publish category limits with an oil, we may store and display those values.
- Product pages can show a category table so you can compare limits side-by-side.
- Fragrance Lab tools (for example, the Idea generator and formula flows) may use those numbers as starting guidance—not as a guarantee that a finished product meets every rule in your jurisdiction.
Supplier documentation can vary in format and interpretation. Limits can change when suppliers reissue certificates. Always verify the latest IFRA statement from your supplier for the specific batch you are using.
Practical reminders
- Local laws, product claims, and labeling rules may differ from IFRA category framing.
- Reformulations, dilutions, and bases can change how a finished product should be evaluated.
- If you are unsure, work with a qualified professional for compliance in your market.
