Can this be considered to constitute an adulteration or simply a tool required for the production of the oil ... 

ISO standard 8897 shows character and data for this oil. J. communis oil is often mixed up with J. oxycedrus. As marker for that the myrcene content is rising up. Real markers are germacrene D- and 8-cadinene. The sesquiterpene fraction gives more information. Further on, addition of fractions of juniper berry oil from recti cation as well as adding juniper branches oil is made. Kartnig et al. (1999) published some chiral data comparing self-distilled and commercial qualities of juniper berry a- and P pinene, limonene, and terpinen-4-ol oils. Chirality was recognized as useful components for quality control of that oil. Mosandl et al. (1991) report a ratio for (5)-(-)-a-pinene 77% -)-(+)-a-pinene 23%.

The phenols are the principal constituents of thyme oil, thymol being the most valuable for medicinal purposes, but carvacrol, an isomeric phenol, preponderating in some oils. Cymene and f-a-pinene are present in the oil, as well as a li tie menthone. Bomeol and linalol have been detected in the high boiling fractions of the oil, and a crysta line body melting at 169 and having the formula Cj sjOj.
