A closer look

What the research shows

Safety assessment

Assessment supports anethole use under the assessed fragrance exposure conditions. It identifies weak skin-sensitization potential and uses trans-anethole read-across for several endpoints.

What this does not tell us

Indexed primary report text verified; complete live full-text access was limited. Safety depends on exposure assumptions and sensitization-risk controls. The assessed isomer-unspecified material is not proof of universal tolerance, allergy-free use or skin benefit.
