How long is the shelf life of poppers? It is stored at room temperature

The premise is that it is only opened several times and rarely used. How long will the chemicals in poppers be in the bottle

How about storing the bottles in a mason jar in the fridge?

@Andy....Lockerroom poppers have lasted me 5 days so far...opened and used at RT. Still good odor, and gas hisses upon opening. I have never bought any OTC poppers that did that.

It's hit or miss really. But I've had good bottles last 2-3 weeks with mild useage. I have wondered though about degradation after opening the bottle the first time versus multiple times. Does quality diminish more and more after repeated bottle openings ( which stands to reason ) Or does it really not matter that much after the initial opening. Meaning that the damage is badically done once its opened the first time and repeated openings after that do not really speed up it going bad. Maybe others with more knowledge can chime in.

Thank you. I want to know how long it will take for poppers to disappear. It needs professional personnel to help. The premise is that poppers have been used ten times and then placed at room temperature

I don't think you'll like the answer.

Un-stabilized alkyl nitrite has an r-R-ONO BDE ) bins dissociation energy) that is very low, roughly 45kcal/mol.

That number probably doesn't mean much to you, it is roughly 2 electron volts, or roughly 3.204353130e-19 volts, which is miniscule.

This means that the alkyl nitrite will fall apart just standing there in the bottle, it's a very fragile liquid.

Various manufacturers use different methods to attempt to stabilize, but they all have downsides.

Potassium carbonate is known to allow down degradation at 1% w/v. It was used in the glass ampoules of prescription amyl (mixed isomers) nitrite that was by prescription, as degradation has build up could cause the thin walled ampoules to burst.

Down side of it can cause a pink paste like precipitate of used in excess, and it kills the has buildup of NO, which used to be an indicator of freshness.

Activated alumina or molecular sieve will adsorb water (and some gases). The original 'power pellet' didn't have the aluminum or zeolite substrate that today's adsorbents do, so it works actually dissolve in the nitrite during use, which rendered it useless.

Today's adsorbents are better.

Various acid sinking compounds.

Since the nitrite degrades so easily, PWD's solution was to include an acid sinking compounds (epoxidized linseed oil) to neutralize acid as it was created.

This, IMO, was a bit of a scam.

It DID allow a tropical customer to have a better experience from storing and sniffing from the same bottle, because as the acidic degradation products built up from poor (any) handling, they were destroyed by the acid sink and the resultant water was adsorbed by the pellet.

The downside was that the product was now only 40% nitrite and 60% acid sink. The bottles would go 'flat' when they became about half full ) all of the nitrite evaporated from the bottle now left with lower vapor pressure acid sink.

A better solution, IMO, would have been to educate people about how to preserve the nitrite (don't store and dose from the same bottle) and they wouldn't be cheated out of half of their money

Remember that the original alkyl nitrites came in two sizes, the 10ml 'pocket' size, meant for one time use while out on the town, and the 30ml 'night stand' size, meant for date night.

None of these were intended to be stored and saved for very long. It was like carbonated soda, when they no longer fixed they were stale and trash.

Nowadays, people seem to think they can get weeks and months out of a bottle, but they can't.

So you question doesn't really have enough delimiters to have a narrow answer.

It depends on nitrite stabilizers, if present, and what your definition of 'gone bad' is

@The Professor: thank you for explaining this, it is a question that has been asked many times.

You opinions on the relative merits and properties of all these nitrites would also be most welcome.

Definitive answers at last :-)

There is a mystery nitrite called Octi (something) did you ever hear of this?

@Mam:
I haven't, sorry

@ The Professor Hello, Do you mean the nitrite content of each bottle of poppers is 40%? Can you tell me what stabilizer is? That is, in addition to nitrite also contains what substances. Because my poppers are gone, I need to know how long the chemicals in them will degrade and disappear. Because it's in a corner of the house. can't find. I'm afraid it's not safe

The Professor said on Thu, 22 Jul 2021 at 13:24...

@Andy:
Not all alkyl nitrite manufacturers use stabilizers. Those that don't tends to degrade and gather noxious Aromas as they age; they are mostly nitrite, and will evaporate entirely if left open.

Those that are stabilized with ELO and adsorbent were (pwd at least) 40% nitrite and 60% ELO.; They won't evaporate entirely, they'll just become predominantly ELO and have no effects.

Things will degrade, but nothing will disappear unless the bottle was open.

@ The Professor Hello, Thank you for your time. Will the poppers containing isopropyl nitrite boil at room temperature of more than 40 degrees and cause the bottle to crack? I'm afraid it will produce an electric spark and cause combustion

The Professor said on Thu, 22 Jul 2021 at 18:31...

No; the vapor pressure isn't strong enough to crack the glass

andy said on Wed, 28 Jul 2021 at 06:21...

I was worried that my lid wasn't 100% tightened if isopropyl nitrite reached 40 degrees boiling point and boiling would break the lid and cause explosion and combustion. Can you help me find the explosion concentration limit of isopropyl nitrite。thanks！
