About TAGETES LEMMONII LEAF OIL

An essential oil from a marigold-related plant that contains thiophene compounds known to cause skin sensitization and phototoxic reactions when applied topically.

Detailed Analysis

Tagetes lemmonii leaf oil contains thiophene derivatives (primarily alpha-terthienyl) that exhibit significant phototoxic activity under UV exposure. The EU does not currently list Tagetes oil in its positive-accessAnnexes but these phototoxic thiophenes would trigger concern under general safety provisions. It is restricted or avoided in many professional cosmetic formulations due to sensitisation potential.
