Stability
CI 73000 exhibits good stability under normal conditions, but it decomposes when exposed to temperatures exceeding 250 °C.
Conflicts
- strong oxidizing agents
- heat (above 250°C)
Safety
Safety Profile
While authorized for use in all cosmetic product types within the EU, and in externally applied drugs (including the eye area), mouthwashes, and dentifrices by the FDA, the synthetic form of CI 73000 has demonstrated strong mutagenic effects in bacterial assays. Furthermore, a comprehensive skin permeation study is identified as a necessary step for complete safety assessment. The Cosmetic Ingredient Review (CIR) has not yet evaluated this ingredient.

Verdict
Due to documented strong mutagenicity concerns in bacterial tests, an unreviewed CIR status, and a medium irritancy potential, its use warrants careful consideration despite existing regulatory approvals for certain applications.
