In December 2013, the California Office of Environmental Health Hazard Assessment (OEHHA) added diisononyl phthalate (DINP) to California's Proposition 65 list as “known to the State to cause cancer” despite the weight of scientific evidence indicating that DINP should not be listed on Prop 65

Currently, there are over 800 substances on the Prop 65 list, including food ingredients and common household products, naturally occurring substances, ethyl alcohol in alcoholic beverages, aspirin and many prescription drugs.  Prop 65 requires anyone doing business in California to label a product unless the anticipated human exposure to a listed substance in the product will not pose a significant risk of cancer or reproductive harm. Labeling requirements for DINP will be effective December 20, 2014.

Under Prop 65, it is the responsibility of California businesses to determine whether a product warning is required. OEHHA has the authority, but is not required, to establish “safe harbor levels” for Prop 65 substances. For carcinogens, the safe harbor level is referred to as a “no significant risk level” (NSRL). Safe harbor levels have been established by OEHHA for only about 1/3 of the listed chemicals.

OEHHA has not established an NSRL for DINP.  Therefore, to support the value chain, ACC’s High Phthalates Panel and DINP manufacturers have calculated a level of exposure to DINP that is not expected to result in more than one excess case of cancer in 100,000 individuals exposed to the chemical over a 70-year lifetime, which is how an NSRL is defined in the OEHHA regulations. The Panel has also developed a workbook to assist companies in estimating potential exposures to DINP from consumer products.

The Panel has presented three webinars to help companies understand how DINP is used in vinyl products and how to use the tools the Panel has developed.

 



Prop 65 and High Phthalate DINP: Estimating Exposure from Consumer Products
May 8, 2014

This webinar provided an overview of Prop 65; gave a brief background on how DINP was added to the Prop 65 list; discussed the development of an NSRL for DINP; and explained how to estimate potential exposures from consumer products using the DINP-specific workbook.

Prop 65 and High Phthalates
March 6, 2014

This webinar provided an overview of Prop 65; discussed how an ACC member company complies with Prop 65; and explained how to estimate potential exposures to DIDP from consumer products using an existing tool developed by ACC’s High Phthalates Panel.
