What Annex III means for STRONTIUM CHLORIDE
STRONTIUM CHLORIDE 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: (a) 3.5% (as strontium) When mixed with other permitted strontium products the total strontium content must not exceed 3.5% (b) 2.1% (as strontium) When mixed with other permitted strontium products the total strontium content must not exceed 2.1%
- Confirm product type compatibility: (a) Oral products (b) Shampoo and face products
- Include required warning statement on product label.
- Document conditions of use in the Product Information File (PIF).
