Because sulfanilamide in pill form had proven safe and efficacious, diethylene glycol
became the prime suspect for the mortalities appearing across the nation.
Equate was launched in 1995 and operates an integrated petrochemical facility that produces more than five million tons of products annually, including polyethylene, ethylene and diethylene glycol

, formaldehyde, and metals.
The National Institute for Health and Clinical Excellence, a non-departmental public body in the UK, released a report saying that e-cigarettes may "contain nicotine derived nitrosamine contaminants and diethylene glycol
, a highly toxic substance".
If the packs become damaged, they can leak gel that could contain diethylene glycol
and ethylene glycol, which can cause illness if ingested in large amounts.
When nicotine is extracted from the tobacco plant, a variety of carcinogenic chemicals may be created in the process, including diethylene glycol

Historically, contamination of propylene glycol USP/EP has occurred with the presence of diethylene glycol
(DEG) or monoethylene glycol (MEG) because of their similar properties and difficulty in analytical separation.
In one example, a 38wt% polyvinylidene fluoride solution in a mixture of gamma butyrolactone and diethylene glycol
was extruded at 190[degrees]C into a 12[degrees]C bath of 80-wt% aqueous gamma butyrolactone, resulting in a hollow fiber membrane.
