As of December 20th, 2014 the labeling requirement for products containing DINP in the state of California went into effect. Any product containing more than the established No Significant Risk Level (NSRL) of 146 micrograms per day must be labeled when sold in the state.
The 45-day public comment period regarding the proposed NSRL was scheduled to end on February 17th, 2015, however California’s OEHHA has extended the comment period until March 11th due to the considerable controversy surrounding the issue.
Also pending is the outcome of a lawsuit filed by the American Chemistry Council against the OEHHA to overturn the listing of DINP as a potential carcinogen, citing lack of concrete scientific evidence. A public hearing will occur in Sacramento on February 25th.
