Updating an issue we have been tracking, the California Office of Environmental Health Hazard Assessment finalized the No Significant Risk Level for DINP of 146 µg/day. The NSRL will got into effect April 1, 2016.
Once in effect, this will be the level of exposure at which a warning is required for DINP. This will remove one of the significant, and expensive, hurdles to defending against a Proposition 65 claim, as a company will not need to develop an NSRL as part of its case.
From a planning perspective, it also allows manufacturers to assess their products and, if necessary, lower the amount of DINP in the product that may result in an exposure.
