The wiki article for Febreze is very odd. At least a third of the edits (in terms of characters) were done by single-purpose IP addresses, see https://xtools.wmflabs.org/articleinfo/en.wikipedia.org/Febr...
Moreover, the claim you cite references a now defunct website operated by P&G from 2005, archived version (it automatically downloads a perl script on my PC...): https://web.archive.org/web/20060515060609/http://www.scienc...
It seems that the P&G article promotes Febreze as a fabric refresher. It does not tell anything about the air fresheners from the same brand which are the topic of this thread.
