Popular questions
  1. What is blue 1 made of?

    A synthetic triarylmethane dye used as a food color; it's the disodium salt of a sulfonated aromatic compound and is water‑soluble. An insoluble 'lake' form is made by depositing the dye onto aluminum hydroxide for use in fats and coatings.

  2. What does blue 1 do to your body?

    At typical dietary levels it has no known physiological effect; most ingested Blue 1 is poorly absorbed and is excreted. Rarely, sensitive individuals may have allergic-type reactions or temporary blue-green stool/urine.

  3. Is blue 1 dye bad for you?

    No—major regulators (FDA, EFSA, JECFA) consider it safe at permitted levels, with an EFSA ADI of 6 mg/kg body weight per day. Adverse reactions are uncommon and usually limited to rare hypersensitivity.

  4. How is blue 1 made?

    It’s synthesized from petroleum‑derived aromatic compounds by constructing a triarylmethane core, then sulfonating and oxidizing it to a water‑soluble disodium salt. The 'lake' form is produced by precipitating the dye onto aluminum hydroxide.

  5. Does blue 1 cause cancer?

    Current evidence does not show that Blue 1 causes cancer at permitted food-use levels. Long-term animal studies and evaluations by EFSA/JECFA have not identified carcinogenic or genotoxic concerns.

  1. Who is the green symbiote in venom 3?

    That’s unrelated to this additive; E143 (Fast Green FCF) is a synthetic green food dye used as a colorant—approved in the U.S. but not permitted in the EU.

  2. Can i travel 3 months before my green card expires?

    This concerns immigration, not the additive; E143 (Fast Green FCF) is an artificial green dye used to color foods and is not allowed in the EU.

  3. Why has my poop been green for 3 days?

    Ingesting artificial food dyes such as E143 (Fast Green FCF), which is poorly absorbed, can turn stools green as the color passes through. If it continues without dye-rich foods or you have other symptoms, seek medical advice.

  4. Who was the green symbiote in venom 3?

    That’s about a movie character; E143 (Fast Green FCF) is simply a synthetic green food dye and has nothing to do with symbiotes.

  5. Why is toxin green in venom 3?

    That’s a movie design choice; E143 (Fast Green FCF) is a sea green synthetic food dye whose color comes from its light absorption, and it isn’t related to character colors.
