There have been some concerns that -NOLs will oxidise to form -NONEs, although I have old bottles of NOLs that don’t smell like they have converted to NONE. One other forums there have been random rumors that NOL will convert to NONE within minutes. Then there is the thinking that skin bacteria are the responsible agent. I have these gas cylinders that contain mostly Carbon Dioxide at low pressure that are supposed to protect wine against degradation. Do you have any ideas about the experimones being sensitive to oxygen ? It would be a simple matter to shoot a gas layer into a half full bottle. How about heavy noble gas like Krypton ? There’s a commercial Kp/Xe mix about 4.5 x the density of air ? ---

Hmmm… It was my understanding that it is the bacteria on your skin that cause the conversion. Also, I thought it took hours, not minutes. Like 7 hours? ---

Aurelie is right. Bacteria on your skin is the major culprit with the conversion of Anol to Anone. Little is known on how long the process takes before conversion takes place, but general estimates/consensus is around 8 hours. I suppose it also may have to do with how much bacteria you have on your skin at any given moment. I’ve been told oxidation has little to no effect on anol to anone conversion. I suppose air-born bacteria could contribute to conversion, but thats just a guess. There is also the issue of evaporation when exposed to air. I personally put my bottles in a zip-lock bag in cool dry place away from light. This is probably not necessary, but better safe than sorry. ---

For conversion I have 7 to 9 hours stored in my brain, based on some research article I once read. Unfortunately I cannot post the link right now. But back to “Long term preservation of partially filled bottles”. Hmmm… mine don’t last long enough to really worry about it. 🙄 I think we need expert advice from MHarris on this one. I tend to store mine at room temperature away from daylight. ---

O2 doesn’t do much of anything to androstenol (O3, of course, will “destroy” it). Estimates by our main chemist are that androstenol will remain stable for at least 15 years. Like anything volatile, though, keeping products in a dark area, away from excesses of heat (I wouldn’t worry about cold), is generally a good idea. Dark amber or blue glass to block UV. There are molecules that aren’t stable, but androstenol isn’t one of them. All of the [pheromones](https://a314.com/shop/) we deal with have a great deal of stability. Much better than many used by the fragrance industry. ---

Good to know that… was considering a few mg. of BHT crystals to reduce spoilage… prob. won’t be necessary… As a precaution I flush my partially filled bottles with a wine preservative gas product, stated as a mixture of N2, CO2, and Ar. Seems a touch cheapo for my style. Spoke with an industrial gas dude, he like sulfur hexafluoride, stuff’s dense, 5x as dense as air, non reactive, makes an excellent blanketing agent, and mucho cheaper that Xenon with a specific gravity of 4.5, although I can use xenon in my excimer lasers to annihilate my enemies at a distance…😮 ---

That’s nice to know then. ---

It is nice to know 😃 Dont let that secret out though… it could be used for all the wrong reasons.. ---

Sunlight will destroy stuff faster than oxygen, though O2 can be a problem. A little dose of an antioxidant might prolong the life of the 'mones, but you’d have to test a few, since they might otherwise react with the mones. ---

Oh, I have an even better idea: Get one of those bottles of “wine preserver.” It contains argon, a heavy, nonreactive, nontoxic gas. It is heavier than oxygen, so it will form a layer over your mones, keeping oxygen out.
