Mechanism of Action
As an anthraquinone-based dye, Disperse Violet 4's mechanism on the skin is limited to the physical deposition of pigment. It serves to color the surface, creating a bright blue-purple aesthetic effect, without contributing any biological or therapeutic actions to the skin itself.

Safety
Safety Profile
Disperse Violet 4 is associated with GHS hazard statements H315: Causes skin irritation and H319: Causes serious eye irritation, as well as H335: May cause respiratory irritation. While the CIR has not specifically reviewed this ingredient, the SCCS found a related substance (Disperse Violet 1) safe for hair dye up to 0.5% on-head concentration. However, the U.S. FDA has indicated 'No batch ever certified' for 'D&C Violet No.', suggesting it is not approved for direct cosmetic contact. It may be used as a component in products covered by a group standard.
