Safety
Safety Profile
Disperse Red 11 is listed in the EU Cosmetics Inventory; however, no specific FDA approval status for cosmetic use has been identified. Dermal irritation studies in rabbits reported moderate to mild irritation depending on the dye lot, while eye irritation studies were negative. GHS classification indicates it can cause skin irritation, serious eye irritation, and is harmful if swallowed. Conflicting data exists regarding its sensitizing potential: one safety data sheet suggests it is not a skin sensitizer, while another source indicates a higher likelihood of sensitization in some individuals. It is also identified as a potential endocrine disrupting compound.
