Blue 1 (Brilliant Blue)
Score
30
Synthetic dye with a cleaner safety record than the azo dyes, but still purely cosmetic.
Blue 1 is not part of the EU's warning-label set and reviews have been broadly reassuring on toxicity. We still score it below neutral because it signals a formulated product and delivers zero nutritional value.
