The California Office of Environmental Health Hazard Assessment (OEHHA) last year added DINP to Proposition 65, which requires the labeling of products containing any one of the approximately 800 chemicals of concern identified by the state.  

Under the federally mandated Consumer Product Safety Improvement Act (CPSIA), DINP is restricted to maximum levels of 0.1% in mouthable toys and components and remains legal for use non-mouthable toys and inaccessible components. There is little evidence and significant doubt that DINP is harmful to humans.

Toy Industry Association (TIA) members and industry stakeholders that sell toys in California are advised to include the required warning label on all packaging of products that may contain any levels of DINP. Questions may be directed to TIA’s Alan Kaufman, senior vice president of technical affairs.
