Baby Powder smell when first take mask off?

[palerider]

Our sense of smell was designed to work under normal air pressure and normal flow into the sinuses. When your cpcap machine is on both pressure and flow increase, so basically your sense of smell is suspended

*TOTALLY* untrue.

As soon as the machine is off or the mask comes off, your olfactory receptors can function again and the first things they pick up are the silicon molecules that were very recently rushing through (remember that your sense of smell is designed to picks up changes in the concentrations of gases. When you smelling "nothing" it means "no change").

NO, this is false.

The air rushing through the hose is required for the concentration of molecules in your nasal cavity to get high enough so that the odor is fairly strong.

Nope.

I admit I was not able to confirm that the hose contains silicon, but it is flexible and can withstand heat, so it's likely given that 1) descriptions of the hose say "latex-free", and 2) most of our hoses are heated, and silicone is famous for being able to withstand heat without breaking down, which is why they use it for injection molding and to make trivets.

Batting a thousand, the hose doesn't even heat up to *BODY TEMPERATURE*.

But maybe it is coming from the machine itself. If someone had a machine long enough for the smell to go away, then got a new hose and the smell did not return, that would be good evidence of that.

I wish new people would avoid dredging up old, dead posts to spew their crackpot theories upon.

The smell came from a new hose for me, the smell went away after a week of use.

That's a helpful piece of evidence. Thanks for sharing.

That's a helpful piece of evidence. Thanks for sharing.

More evidence:

Last night I farted in bed and about 30 to 45 seconds later I smelled sh*t.
It went away after about one minute.
You are welcome.

Always the helpful one.

Baby powser smell would have been preferable.

I have another theory:
It is quite possible that cpap treatment is improving your health to the point
that your body odor becomes pleasant.
When you remove the mask--you smell YOURSELF!
The baby powder identification is just the brain trying to connect the dots.
Conversely, sweet smelling sweat can be a symptom of a metabolic disorder.

I appreciate the thought.

The problem with it is that it takes people a long time to get used to sleeping with the mask on (average time is said to be 30 days), if they ever do, and thereafter experiencing the health benefits. But this phenomenon is happening to people from day one, before any health benefits have occurred.

[chunkyfrog]

And who knows how many of them are just bitching about that "G--D" CPAP.
Confess--is that you?

You have a crack pot idea, and it is wrong.

Give it up, and please don't dredge up any other old threads to add your special odors to.

[chunkyfrog]

PR, I have to agree.
Crack pot, quite likely.
Hallucinations due to brain damage, if really experienced.
Time to see a doctor (if real)
More likely, some loser trying to get attention by wasting our time.
Good bye, TROLL.

After doing more research, I have a better theory as to the source of the baby powder smell (than what I posted above). The problem with my earlier explanation is that silicon and silicone are described as odorless; while baby powder gets its unique scent from the fragrance they add to it (actually a blend of fragrances). In a nutshell, I think the hose manufacturers are adding the same fragrance to the material to mask what would otherwise be a "chemical" smell. The material is likely a mixture of plastic and silicone, the smell of which, while not toxic would probably "put off" a lot of people. The problem is they can't really air them out once they're made. Hoses and breathing tubes have to be produced in a sterile environment and packaged while sterile. Laying them on trays or hanging them up to outgas is impractical and would be costly. So, they seal the finished hoses in plastic bags quickly after they are made, but that locks in the odor of the material. And that's the problem they solve by adding the fragrance into the mixture of polymers.

If the hoses came off the assembly line with no odor and they added the fragrance in anyways...? That would be really surprising and kinda dumb/wasteful.

The weird thing is, what's one of the things you never want to breath in? Dust. And what is (baby) powder but fine dust? So, despite its nice smell and pleasant connotations/ memories, the baby powder scent causes new users to be like, "Wait, have I been breathing in baby powder?" (So, they turn to the internet and they find this glorious thread.) But why they chose that particular fragrance blend, ie the baby powder fragrance blend is kinda baffling. It probably comes down to money.

If any lurking titans of industry or just plain factory workers with inside info want to straighten me out, enlighten us, I'd welcome it.

[Julie]

That 'dust' is talc, and thousands are now in court suing the mfgrs over it because it's caused cancer in many, and is therefore the last thing they'd put in Cpaps!

I really think you need to stop your nonsense.

[DFColangeli]

@ Julie, What did I say that is nonsense?

Troll or brain damage, it does not belong here.

Yes, sometimes it is hard to tell the difference between an idiot and a troll... but no matter which

Which one is DFColangeli? perhaps we should have a poll
