Since the beginning of this year, the state of California has listed Diisononyl Phthalate (DINP) on its Prop 65 list which requires additional labels on products found to expose users to amounts above the established No Significant Risk Level (NSRL) of 146 micrograms per day of DINP when sold in the state of California. At the end of June, the California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) issued a Safe Use Determination (SUD) for vinyl flooring products containing DINP. The SUD applies to non-textile vinyl flooring products used in residential, commercial and institutional buildings and can apply to either sheets or tiles. The SUD issued determined that vinyl flooring products containing 18.9% DINP or less is at or below the NSRL of 146 micrograms per day and are so would not be subject to the labeling requirements. This issuance comes in addition to existing SUD’s issued for PVC roofing and vinyl carpet tiles also containing DINP.
