Chemical identity and properties

Sodium Picramate
Sodium picramate, wetted with not less than 20% water appears as a slurry of dark red crystals. Highly explosive. Burns vigorously when dry. May explode if in large quantities. Burns when wet, but difficult to ignite. Produces toxic oxides of nitrogen during combustion. — CAMEO Chemicals

What Annex III means for Picramic Acid and Sodium Picramate
Picramic Acid and Sodium Picramate 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 2 CosIng inventory ingredients for name and identifier cross-reference. The page also surfaces 12 related annex records with overlapping identifiers, annex logic or naming patterns.
Compliance checklist
- Ensure formulation concentration does not exceed: (b) 0.6 %
- Confirm product type compatibility: (a) Hair dye substance in oxidative hair dye products (b) Hair dye substance in non-oxidative hair dye products
- Include required warning statement on product label.
- Document conditions of use in the Product Information File (PIF).
