What it is
Tagetes erecta, commonly called Aztec or African marigold, produces flowers rich in carotenoids, notably lutein and zeaxanthin, which give the petals their orange-yellow color. In cosmetics the flower extract is used as a conditioning botanical and as a source of antioxidant carotenoids, and it can also lend a subtle natural tint. In sunscreens it appears as a supporting ingredient rather than a UV filter.
Safety & warnings
Tagetes erecta flower extract is generally distinguished from the more strongly restricted Tagetes essential oils; the flower extract is typically well tolerated, though as an Asteraceae-family botanical it may rarely cause sensitization in those allergic to daisy-family plants.
Origin & sourcing
Natural. It is obtained from the flowers of the marigold plant, Tagetes erecta.
History
Marigold has a long ornamental and cultural history in the Americas and Asia, and Tagetes erecta is widely cultivated commercially as a source of lutein.
