EU fragrance allergen labeling
Which fragrance allergens must be named on an EU label, the 0.001 percent and 0.01 percent thresholds, what Regulation (EU) 2023/1545 changed, and what the two 2026 and 2028 dates actually mean.

What you can and cannot say
Natural, clean, chemical-free, hypoallergenic, long-lasting: which claims are allowed, which need evidence you must already hold, and which turn your perfume into a different kind of product.

Candles, diffusers and room sprays
None of them is a cosmetic, so the cosmetics rules do not apply and a different set does: CLP classification and labeling, IFRA categories 10 to 12, and general product safety.

Safety data sheets and CLP labels
When a fragrance needs a safety data sheet and when it does not, what the sixteen sections must say, where a classification comes from, and what goes on a CLP label.

Weighing, dilutions and strength

When a material you rely on is restricted
What to do when a limit drops or a material is prohibited: how to tell which of three problems you have, how long you have, how to substitute properly, and what paperwork the change drags behind it.
