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.
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.
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.

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.
Does blue 1 cause cancer?
