Several chemicals added to California Proposition 65 over the past year are coming into effect within the next few months.

One of the chemicals, the Phthalate DINP, may be used as a plasticizer in EEE. The addition of DINP to California Prop 65 has been controversial. The American Chemistry Council launched a lawsuit against the California Office of Environmental Health Hazard Assessment with respect to the addition; however, the Court will not rule before civil enforcers can begin filing notices. The deadline for manufacturers to provide the Prop 65 warning label on products that contain DINP and are potential exposure risks is December 20, 2014.

Other substances with deadlines in January-May 2015 include Trichloroethylene (TCE), Methyl Isobutyl Ketone (MIBK), Pulegone, N,N-Dimethyl-P-Toluidine.
