What Annex III means for HC Yellow No 13
HC Yellow No 13 is a restricted substance under Annex III of EU Cosmetics Regulation 1223/2009. Its use in cosmetics is only permitted under the specific conditions set out in the entry above, including applicable concentration limits, product type restrictions and required warning statements.
When including this substance in a formulation, all conditions — maximum concentration, product scope and warning labels — must be met simultaneously. Compliance with one condition does not override the others.
This record is linked to 1 CosIng inventory ingredient for name and identifier cross-reference. The page also surfaces 12 related annex records with overlapping identifiers, annex logic or naming patterns.
Compliance checklist
- Confirm product type compatibility: (a) After mixing under oxidative conditions the maximum concentration applied to hair must not exceed 2,5% For (a) and (b): - Do not use with nitrosating agents - Maximum nitrosamine content: 50 microgram/Kg - Keep in nitrite-free containers
- Include required warning statement on product label.
- Document conditions of use in the Product Information File (PIF).
