Introduction - FDA issued a guidance document
in May 2007 that recommends that pharmaceutical manufacturers, repackers, and
other suppliers of glycerin, and pharmacists who engage in drug compounding
ensure that the glycerin they buy, sell, or use is not contaminated with diethelyene
glycol (DEG), a poison. The FDA guidance also recommends specific analytical
test methods that include a limit test for DEG.
While the FDA guidance focuses on the pharmaceutical industry, this may also concern many in the dietary supplement industry who use glycerin in extracts and other products.
