Is it a concern?: Moderate concern: no hazard classifications on record. It is listed for cosmetic use in the EU.

What the listings say

Permitted, with conditions — FD&C yellow no. 5 appears on published "allowed" regulatory lists rather than on a restriction list.

Trisodium 5-hydroxy-1-(4-sulphophenyl)-4-((4-sulphophenyl)azo)pyrazole-3-carboxylate and its insoluble barium, strontium and zirconium lakes, salts and pigments is listed in Annex IV of the EU Cosmetics Regulation (EC) 1223/2009 (colorants allowed in cosmetic products).

The score describes this ingredient's chemical identity — its hazard profile from published classifications and regulatory status — not the safety of any product it appears in.

Suitability

Context-specific fit derived from published classifications and the current ingredient evidence profile.

Food use

Food-use source coverage is present in the current record.

Good fit

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.

Fragrance avoidance

Not a strong fit for fragrance avoidance because it carries Fragrance.

Avoid

The ingredient itself is a fragrance-linked signal, so it is better treated as an avoid case when fragrance exposure is the main concern.
