Official EU ingredient-name evidence

The ingredient name exactly matches the official 2025 EU glossary of common ingredient names.

#13285 · HYDROXYISOHEXYL 3-CYCLOHEXENE CARBOXALDEHYDE

Declared fragrance allergen

This substance is on the EU list of fragrance allergens that must be named individually in the ingredient list, rather than being covered by the word "parfum", once it exceeds 0.001% in a leave-on product or 0.01% in a rinse-off product.

This substance is also prohibited in EU cosmetics, so the declaration applies only to an unintended trace that Article 17 tolerates — not to anything deliberately added. See the allergen record
