Legislations concerning Ethanol purity
My research work deals with the quality control of ethanol-containing products, in particular, the quantification of volatiles by GC methods.
The question is following: which documents are legislations in EU for the amounts of volatile impurities in pure ethyl alcohol (96%)? Also I wonder if there are various ethyl alcohol "grades" which differ from each other by volatiles content. I know the Comissions Regulations 2870/2000 and 110/2008 but this documents don't contain necessary information. Currently, the European Pharmacopeia is the only one legislative document I found, which contains specific permitted values of impurities. I will be grateful for any useful information. Also I would like to find such legislations for any other countries, for instance USA.
Thanks in advance.
