Can perfume "go bad" over time?

It's not so much that is goes bad as in "rotten."  The plant essences/extracts that it is made from get rancid.  It's going to go bad faster if it's exposed to high temperatures and if you chose to keep it in the fridge you could make it last longer...but applying icy perfume doesn't sound like much fun to me.

I guess you need to use a phtse transfer catalyst (PTC). Since most of the perfumes contains alcohols, you can give a try using alcohol as PTC.\n\nJust dissolve your perfume in MINIMUM amount of methanol/ethanol. And then add water to it.... \nFor most of the cases this will work!\n\nGood Luck!

Most medication, in pill form, is good for one year from the date purchased ... then it's abilities start to diminish.

Try Redken Willpower. Man, a little of that stuff goes a long way, and it never goes bad. I have this small bottle I've been working on for 3 years. It really holds and has no scent whatsoever. It ROCKS.

Yes, I've mailed perfume to NSW to a freind. Just make sure to list it on the Customs form. and check off "GIFT" on the form.\n\nChris

Avg life of CD could be about many years, if they are stored. But if they are constantly being used...it will slowly start wearing out (mostly because of the scratches cuased by dust particles, esp in the CD Drive).. but even then it will easly last few years.

There are lots of Perfumeries in Grasse, France. Try hooking up with a website there. The one I went to made all the bases for most of the famous brands available.

No. It gets old after awhile. Must be those addictive ingredients. Hmmm.

theres a perfume called poison. It was popular in the 80s I think... Other than that I think that poison is just a title given to liquids that have harmful side-effects if they're ingested.

if you keep it for a while it starts to stink

I dont know that I would say spoil but when cologne or perfume is in the heat or sunlight for too long the chemicals in it change and so the the scent.  It can smell down right nasty after a long time in the sun.  I keep mine in a dresser drawer.

Check the expiration date on the carrton or if it smells particularly sour.  If it has not been stored at the proper temperature (below 45 degrees) for longer than two hours harmful bacteria can form and you would not be able to smell or taste that bacteria but it will make you sick.  Best not to risk it.

I don't think it will really expire.  My parents have bottles in their liquor cabinet that are twenty years old and are still good.  Keep it tightly closed and in the freezer.  It is much better ice cold anyway.

That is definitely not good. I think you are well within your rights to report her, products have a sell by date for a reason, the reason being they go bad after a while. For something like medicine, this could be really serious. If she is a cow anyway, get the horrible woman into trouble, she is doing something really unresponsible.

Not really, smell goods are usually a good gift idea, I like scented baths, my husband buys them for me :)
