California EPA’s Office of Environmental Health Hazard Assessment (OEHHA) has issued a notice of intent to list ethylene glycol (EG) as known to the state to cause reproductive toxicity under the Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65).

Used in the manufacture of polyethylene terephthalate resins (PET), which are used in bottling, the chemical has been reported for its potential human reproductive and developmental effects by the National Toxicology Program in a 2004 monograph that “identifies EG as causing developmental toxicity in laboratory animals, and satisfies the formal identification criteria in the Proposition 65 regulations,” according to OEHHA. Public comments “as to whether ethylene glycol meets the criteria set forth in the Proposition 65 regulations for authoritative bodies listings” are requested by May 12, 2014. Companies making and selling products containing chemicals listed under Proposition 65 are required to disclose exposures to California consumers or face fines for failure to do so.
