Dusting Analysis
CI 40820 is a colorant, not an active ingredient typically associated with visible residue or 'dusting' in the context of therapeutic efficacy.
The Formula
Formulation
Stability
As a carotenoid derivative, CI 40820 exhibits enhanced solubility in acidic conditions, with an optimal pH for dissolution around 6. Elevated temperatures can diminish its storage stability, and a high water content in a formulation may reduce its overall solubility.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) typically does not evaluate colorants. CI 40820 is regulated under Annex IV of the EC Cosmetics Regulation (EC) No. 1223/2009 in the EU as a permitted colorant, though a specific maximum concentration was not detailed. In the United States, color additives such as CI 40820 require FDA approval for their intended cosmetic applications. Notably, it is also approved as a food colorant (Food Orange 6, E 160e), suggesting a foundational level of safety assessment.
