Regulation 2023/1545, which addresses the labeling of fragrance allergens on cosmetic products, was published by the European Union.

It takes effect in July 2026 and mandates the labeling of a total of 80 compounds that have been classified as allergens.

This Regulation introduces several changes to Annex III of Cosmetic Regulation (EC) No 1223/2009.

The list of labeled allergens now comprises 80 entries, and all of the compounds in question must be listed in the ingredients list on the packaging as soon as their concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products.

The purpose of this additional labelling is to inform those sensitized individuals who have been tested and know which ingredients to avoid.

An allergen can be present in a cosmetic product due to:

a) Its presence in the fragrance or aroma mixture either added directly or as part of a natural complex substance (e.g., essential oil, botanical extract)
b) Its presence as constituent of a natural complex substance (NCS) (e.g., essential oil, botanical extract)
c) Its presence as an impurity or contaminant
d) A combination of two or more of the above (no contribution as cosmetic ingredient)
e) Its intentional addition as a cosmetic ingredient (i.e., not a fragrance or aroma mixture)
f) Combination of (e) and one or more of the above.

The new substances that must be declared on the labels when present are:

  • Pinus Mugo
