Safety
Safety Profile
While the Cosmetic Ingredient Review (CIR) has not assessed Tagetes lemmonii specifically, the Scientific Committee on Consumer Safety (SCCS) has determined that other Tagetes species (Tagetes erecta, minuta, patula) are phototoxic. For leave-on products, a maximum concentration of 0.01% is considered safe, provided the alpha terthienyl content remains below 0.35%. For rinse-off products, a maximum of 0.1% is permissible. This ingredient is strictly prohibited in sunscreen products and should be avoided before direct sun exposure due to its photosensitizing potential. General warnings advise against use during pregnancy, for individuals with epilepsy, or on children and babies. It is also noted for high irritancy.
