Two Substances Added to the List of Prop 65

On November 23, 2018, the Office of Environmental Health Hazard Assessment (OEHHA) is adding gentian violet and N-nitrosohexamethyleneimine to the list of Prop 65. At a public meeting on November 1, 2018, the Carcinogen Identification Committee (CIC) in its official capacity as the “state’s qualified experts” (SQE)[2] determined that gentian violet and N-nitrosohexamethyleneimine were clearly shown by scientifically valid testing.

The information of two substances is as follows:

* Listing mechanism:  SQE – “State’s Qualified Expert” mechanism (Health and Safety Code section 25249.8(b) and Title 27, Cal. Code of Regs., section 25305(a)(1)).

Gentian violet is often used in the ink, toner and textile dyeing. It also can be used medically as disinfectant, preservative, cosmetics hair dye.

The California law requires manufacturers and retailers to warn workers and consumers exposed to chemicals on the list.
