No specific rule on file. The FDA regulates few cosmetic ingredients by name; no rule does not mean approval.

Amaranth CI 16185
Information only, not medical advice. Rules change — always check the linked official source. If you are pregnant, have a skin condition or allergies, ask a dermatologist or pharmacist.
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: “Trisodium 3-hydroxy-4-(4'-sulphonatonaphthylazo)naphthalene-2,7-disulphonate (Acid Red 27; CI 16185) when used as a substance in hair dye products”
In Korea's MFDS records it is listed as “Restricted” (MFDS — cosmetic ingredient use restrictions). 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 적색2호.
2 products we checked list it, for example JMsolution Active Pink Snail Regenerating Mask (10 sheets), Tonymoly Perfect Lips Shocking Lip.
