Food use
Food-use source coverage is present in the current record.
The ingredient appears in food-oriented source coverage or allowed-use references, which makes food use easier to support than a context with no domain signal at all.
2,2'-[(3,3'-Dichloro[1,1'-biphenyl]-4,4'-diyl)bis(azo)]bis[N-(4-chloro-2,5-dimethoxyphenyl)-3-oxobutyramide] is listed in Annex IV of the EU Cosmetics Regulation (EC) 1223/2009 (colorants allowed in cosmetic products).
Concern score
The concern value reflects this ingredient's chemical identity — its hazard profile from the published classifications and regulatory status below — not the safety of a product it appears in. A score near 40 is the baseline for ingredients with no specific signal (water scores 40 by design), so a mid-range value is not a safety verdict.
Concern score 25/100 (minor) · high confidence.
