Question:
is is bad to shake your cologne bottle before you spray?
i'm thinking it will increase its scent concentration since the oils may settle and make it overall more effective and balanced.
thanks.

Answer:
Well, the part that you're actually applying to yourself was already in the sprayer tube. It won't move even if you shake the bottle.
Plus, I think that if the oil were settling, there would be a visible effect, especially with clear bottles. I don't there should be an issue.

Answer:
hmm...bubbles

Answer:
Is it bad to shake them? I doubt it, but I also doubt there's any benefit. You could always spray one side of your body before shaking, then shake it like a polaroid picture and spray the other side of your body. Then see if you notice any difference during the day on the shook versus unshook side.
Wasn't there a Halston fragrance that separated, when at rest, into two different colors, and one was supposed to shake vigorously so the two parts would mix before applying? I thought it was Catalyst, but a quick google suggests I'm remembering wrong. Hmm.

Answer:
I've seen mentioned here that you ought not to shake them, because it exposes more of the fragrance to air than otherwise would be (the air in the bottle, but I suppose it might make a difference). Since there's no visual effect I've ever noticed other than the occasional bubbliness, I would be inclined not to shake.

whoever it is, step up. My friend,
I think it is best if you decide that it just doesn't matter. You asked your question, and you can take comfort in the fact that members can and will reply to it if they believe they can be helpful to you. I note several examples of that on this thread already.
Any further communication about this you can send to me by PM and I'll be glad to help out. That will keep your thread on topic, and get you more answers to what you really want to know, as well.

Answer:
I would agree with Schareid that shaking the bottle will shorten the life of the fragrance by putting oxygen into the juice. Oxygen is highly reactive and will over time destroy you cologne.
I also agree with several comments which observed that because of the uniform appearance of the juice that shaking will have no benefit.
So I would suggest making an effort to NOT shake your fragrances.

Answer:
i actually don't shake like a can of creme..i turn it upside down a few times gently. it still causes bubbles though.

Answer:
I usually shake...sometimes violently, but when I'm worried about not spilling my last bottle of Patou, I think it is normal to shake...or are you talking about shaking the bottle?..never mind!

Answer:
It was the Halston Catalyst aftershave that separated and had to be shaken, to answer a previous question.
I once found an old bottle of Obsession for women in one of my parents' bathroom cupboards that has been there for literally many years, untouched. I sprayed some on (enough to clear the tube... which was obviously too much), but it smelled totally wrong. The next day I went back, shook up the bottle, sprayed a few sprays to again clear the tube, and sprayed it on- and it was back to the Obsession that I remembered.
I doubt, though, that any of our stuff is going to be sitting around long enough for this to happen. I also doubt that shaking too much is going to in any way "damage" the fragrance, by why take the chance?
