Stability

CI 16185 is stable within a pH range of 2-11. However, as an azo dye, it can undergo photocatalytic degradation, potentially forming aromatic amines; a UV filter is recommended for color stability.

Conflicts

  • Strong hydrochloric acid can cause browning and black residue.
  • Photocatalytic degradation can form potentially carcinogenic aromatic amines.
  • Not recommended for surface-adhering color in creams, lotions, gels, or serums.
