In personal care
A synthetic azo dye identified by its Colour Index number, producing a bright pink-red shade. It is water-soluble and used to tint formulas rather than to do anything to the skin.
Why it’s used
It gives color to products like soaps, bath products, and some cosmetics, allowing a consistent, vivid red-pink hue batch after batch.
What the evidence says
We haven’t found a source for this one that you can open and check, so we’re not summarizing the evidence.
Look it up yourself
We would rather point you at the shelf than summarize something you can’t check. These are the same places we search:
- PubChem — what the substance is, chemically — names, synonyms and structure
- PubMed — every paper indexed by the US National Library of Medicine that names it
These are starting points, not our findings — we haven’t run them for you. A substance whose name is also an ordinary word (“Heart”, “Alanine”, “Water”) will return papers that are not about the ingredient at all.
