In the EU's CosIng records it is listed as “Prohibited only in certain forms or uses” (EU CosIng — Annex II). The same records also list it as: Approved colorant. It is not a general ban — the condition reads: “2-(6-Hydroxy-3-oxo-(3H)xanthen-9-yl)benzoic acid; Fluorescein and its disodium salt (Acid Yellow 73 sodium salt; CI 45350), when used as a substance in hair dye products”
In Korea's MFDS records it is listed as “Restricted” (MFDS — cosmetic ingredient use restrictions). The maximum allowed is 6%. A restricted ingredient is allowed within the stated conditions.
We found no specific rule for it in the FDA's records. That is not an approval or a safety statement.
The EU's CosIng inventory lists its functions as: colorant.
Korea's MFDS standard Korean name is 황색202호의(2).
