AHPA has published a resource document that describes test methods that can be used to identify ethanol.

Dietary supplement operations are required to confirm the identity of non-dietary components used in their products and determine whether other applicable components’ specifications are met. To fulfil these requirements, manufacturers need to conduct appropriate tests or examinations or rely on certificates of analysis from suppliers of these components, provided that the criteria listed in 21 CFR 111.75(a)(2) are satisfied.

“This AHPA resource will be useful for companies that receive a clear liquid in a jug labeled ethanol,” said AHPA Chief Science Officer Maged Sharaf, Ph.D. “It will help them verify the identity of the liquid in order to satisfy dietary supplement manufacturing requirements enforced by the Food and Drug Administration.”

The document was developed with extensive input from AHPA members and will help AHPA members conduct appropriate testing to identify ethanol. It covers a number of physical, chemical, spectrometric and chromatographic methods for the identification of ethanol.

The document is not an exhaustive collection of test methods for ethanol and other methods not included in the document may be equally suitable.

The Botanical Safety Handbook, Second Edition includes:

  • Easily understood classification systems to indicate the safety of each listed species and the potential for drug interactions
  • Information on adverse events reported in clinical trials or case reports 
  • Safety-related pharmacology and pharmacokinetics of each herb
  • Additional information on the use of herbs by pregnant or lactating women 
  • Toxicological studies and data on toxic compounds 
  • Extensive references for each entry

The book is available in hardback print and online formats. Both versions contain the same information, but the online version, which is optimized for smartphones and tablets, has several additional attributes. Some of these relate to its operation, as it allows subscribers to search for keywords and botanical names and easily access the information they use most by saving personalized lists of entries. Perhaps more importantly, the online version will be updated regularly with new research, and subscribers will be notified of updates to provide immediate access to the most current information. The standard retail cost for either version is $119.95 (one-time cost in print; a renewable annual subscription online). We are discounting the cost for our members and would be happy to offer a discount to other organizations. A free preview of several entries are available online:
