Caution
Sensitization risk Moderate

The CIR Expert Panel considers Eucalyptus globulus (a source for eucalyptol, also present in E. smithii)-derived ingredients safe in cosmetics when formulated to be non-sensitizing. While generally well-tolerated, the presence of compounds like limonene can trigger allergic reactions in sensitive individuals, and very sensitive skin may experience irritation. The essential oil form is typically advised against during pregnancy and for asthmatics due to its 1,8-cineole content.
