Ingredient

Hydroxycitronellal

Neutral in 1 Flagged in 11

Scout's take

EU 26 fragrance allergen and well-documented strong dermal sensitizer. The closely related Hydroxyisohexyl 3-Cyclohexene Carboxaldehyde (HICC / Lyral) was banned by the EU in 2021 for the same class of sensitization issues; hydroxycitronellal itself remains restricted but is repeatedly cited in patch-test registries as a top fragrance allergen.
