Our take
Is Orange 4 (CI 15510) a Good Ingredient?
Rated Fair: it does its aesthetic job with no skincare benefit attached, and azo dyes can occasionally cause irritation or staining; some regions also limit its use by category and level. That's acceptable for a colorant but not enough to lift it into Good territory.
