The 26 allergens a label must name

Regulation (EC) No 1223/2009, Annex III lists 26 fragrance substances a cosmetic label in the EU must name individually when they exceed 0.001% in a leave-on or 0.01% in a rinse-off product, because a known share of people react to them: amyl cinnamal, benzyl alcohol, cinnamyl alcohol, citral, eugenol, hydroxycitronellal, isoeugenol, amylcinnamyl alcohol, benzyl salicylate, cinnamal, coumarin, geraniol, hydroxyisohexyl 3-cyclohexene carboxaldehyde, anise alcohol, benzyl cinnamate, farnesol, butylphenyl methylpropional, linalool, benzyl benzoate, citronellol, hexyl cinnamal, limonene, methyl 2-octynoate, alpha-isomethyl ionone, evernia prunastri extract, evernia furfuracea extract. Naming one is a legal duty, not a warning about you; every product page counts how many of the 26 its label names, each linked to its own page.

How a bottle's fit is read from its actives

On a comparison page, "who each suits" is not written per product. It is aggregated over the bottle's named actives from the base's best-for and avoid-for columns by one rule: a skin type is named when two or more of the bottle's actives name it; an avoid is named when any one of them does. A bottle with fewer than two named actives cannot meet the first rule, and the line says so.
