It's both because I'm a cheapskate and I'm a trainee DIY perfumer. So it's for experimenting as much as for me actually using it (if it works). If I'm wrong, I wasted probably about 20 ml of my Prada IdI (worth approx US$8) plus don't worry even after that, I'll still have over 560 ml of that perfume (that's not a typo).
Anyone interested in the result of this experiment can PM me after this weekend where I plan to experiment (courier says my shower gel base arrives tomorrow). If there's enough interest, I'll post the results here.
well there's a few ways of going about it, you can try and burn it off (no kidding), it should stop burning once you hit the end of the alcohol, but you will lose some of the topnotes for sure - how much you lose will be the experiment. either way it will still smell like the original frag. just put it in a really shallow container like a dinner plate for example, so you stretch the surface area to a max and ignite it, dont use matches!!! you might transfer that yucky smoke smell.
You could also try and evaporate it off... using the same concept, use a wide shallow container. depending on the exact formulation of prada, the fragrance components POSSIBLY might start to visibly seperate from eachother as the alcohol they are dissolved in dissapears (not everything is soluble into everything else), so don't panic if you see this happening.
As you were mentioning earlier, something to bind to the alcohol, which I guess you were thinking would create some kind of solid that could be separated from the oil? no... I'm not a chemist but I really doubt that, especially since depending on the formulation of the fragrance there may be some non-ethyl alcohols that actually make up the fragrance itself. obvious problem here as well is that you wouldn't be forming a precipitate that could be removed, since the alcohol greatly outnumbers the oils.
My last idea comes from the fact that a lot of aroma chems have a freezing point which is generally much higher than alcohol, but not all, so you could theoretically get some of them out that way...
If i were you I think I would use the burning technique (short and sweet), as you will probably lose more topnotes via the evaporation technique. The freezing technique will probably only partially effective...
as a student perfumer myself, I can tell you that this experiment will yield no help to you as a student of perfumery though... grade 9 science experiment maybe, perfume no.. I know its difficult to convey a tone of voice on the internet but believe me that I''m not trying to sound like an a**, but what knowledge are you trying to gain from this? it will work to a certain degree, I can tell you that much already - and I guess it sounds kinda fun... but I'm wondering if there is something specific concerning perfume you are trying to learn here. Afterall, we do know the result of the experiment already, the small testable differences would lie of course in the various different formula constructions of other perfumes and their chemical properties, for instance your quantitative results for this experiment would only be applicable to this specific Prada perfume.
also, what shower gel base are you using, like i said unless you know what your doing, its possibly going to separate again shortly after...
I have to get back to the issue of stability in the shower gel medium, the formula for Prada EDT and Shower are probably different because different applications have different limitations and possibilities of what chemicals can be used, so your resultant extracted concentrate may not be stable in your shower gel base, problems will range from discolouration, spoilage of the scent, insolubility, etc
I have a feeling your a beginner who, like all beginners (including myself at a time), thinks this whole fragrance creation thing is alot easier than it really is... so I'm wondering again if theres something specific your trying to test behind this idea, if so its probably better to just ask that question.
have fun whatever you try!
