About [micro-[Carbonato(2-)-O:O']]dihydroxy trinickel

[micro-[Carbonato(2-)-O:O']]dihydroxy trinickel is a cosmetic ingredient used in product formulation. Exercise caution due to limited available safety data.

Detailed Analysis

The nickel carbonate complex raises significant concern due to nickel content. Nickel is a well-known skin sensitizer and contact allergen, and nickel release from cosmetic ingredients is regulated in the EU (REACH restricts nickel in jewelry and consumer products). While the carbonate complex may release less free nickel than simple salts, the presence of nickel in a cosmetic ingredient is inherently problematic. The ingredient is not listed in EU cosmetic regulation Annexes, but the nickel content makes it a concern.
