OEHHA Proposes Proposition 65 Warning Level for Ethylene Glycol

On April 8, 2016, the California Office of Environmental Health Hazard Assessment published a proposed warning level for ethylene glycol of 8,700 micrograms per day.  The deadline for public comments is May 23, 2016. Ethylene glycol, used in antifreeze products and other applications, was listed as a reproductive toxicant via the authoritative bodies mechanism on June 19, 2015 — meaning that the warning requirement for the substance goes into effect on June 19, 2016. Significantly, the listing was confined to the oral route of exposure. Even so, the listing presented some scientific controversy. Notwithstanding a number of studies showing that no reproductive effects would be likely to be seen in humans, OEHHA relied on rodent studies.  Rodent metabolism of ethylene glycol is markedly different, and more sensitive to the substance’s effects, than human metabolism. Of the warning levels established by OEHHA for Proposition 65 chemicals, this one is among the highest. That fact …Read More

Public Comment Period Begins on OEHHA’s Revised Prop 65 BPA Emergency Regulations

The California Office of Administrative Law has published the California Office of Environmental Health Hazard Assessment’s revised emergency regulations on bisphenol A, which means that the public comment period for these regulations ends on April 13, 2016. Once finalized, these emergency regulations will establish the safe harbor method for providing Proposition 65 warnings for bisphenol A in canned and bottled foods and beverages. GLO previously reported on OEHHA’s emergency regulations on bisphenol A (BPA). BPA was identified as a Proposition 65 reproductive toxicant on May 11, 2015, meaning that the warning requirement becomes effective on May 11, 2016.  This substance is used in a number of applications, including the manufacture of epoxy resins used as linings for cans and bottles.  These linings extend the shelf life of food and beverages packaged in cans and bottles and protect them from microbial contamination. Given the ubiquitous presence of canned and bottled foods and beverages …Read More
