  1. How to get e104 form?

    There is no 'E104 form' related to the food additive—E104 is simply the E‑number for the color Quinoline Yellow. If you meant the EU social-security E104 document, that’s unrelated to food additives.

  2. What is e104 certificate?

    There’s no special 'E104 certificate'; E104 is just the code for the color additive Quinoline Yellow (CI 47005). Suppliers may issue a certificate of analysis or specifications for a batch of the dye, but that isn’t an official E‑number certificate.

  3. E104 used in what medications?

    As a colorant excipient, Quinoline Yellow (E104; also CI 47005/D&C Yellow No. 10) is used in some tablets, capsules, and oral liquids where permitted (e.g., in the EU/UK and in U.S. drugs/cosmetics, though not in U.S. foods). Check the product’s excipient list for 'Quinoline Yellow', 'E104', 'CI 47005', or 'D&C Yellow No. 10'.

    That query isn’t related to the food color E104; Quinoline Yellow is a synthetic dye used to color foods and some medicines. I can’t identify people or media from such references.

  5. Fakehospital e104 who is she?

    This isn’t related to the food additive E104; Quinoline Yellow is a coloring agent, not a person. I’m unable to identify individuals from such queries.
