Guest guest Posted October 11, 2005 Report Share Posted October 11, 2005 Hi everyone, I came across this article in a book titled " An introduction to Perfumery " by Tony Curtis an . " An important fact, not always fully appreciated by the newcomer to perfumery,is that the essential oils ,resinoids,concretes and absolutes of perfumery frequently referred to as 'natural products ' are rarely if ever of the same composition as the corresponding materials as they occur in the living plants and animals from which they are obtained. The processes to which natural sources of the aroma are subjected, gentle though some are,expose their volatile constituents to conditions of treatment which will inevitably cause or promote chemical changes, like oxidation, hydrolysis ,thermal decomposition etc. What's everyone's view on this???? Another query is is it harmful if I use methyl alcohol instead of ethyl alcohol,my essential oil supplier says they use methyl alcohol for perfumery.
