I have a question: I got my SN in a black plastic screw cap bottle (im not sure if it is HDPE or PP), it came sealed, but I broke the screw cap seal to open it (i did it only once) to check it out, screw it back, and now the plastic bottle is inside a box in my drawer.
It seems well closed like a normal bottle would be. I opened and closed it over a month ago.
It was manufactured in 2024 and the expiration date says 2030. I don't intend to CTB soon, for now i'm just perfecting the plan,so I'm thinking of keeping it until it expires. But reading this and other threads I got quite confused...
Can the air particles that the closed SN bottle is exposed to be enough to diminish it's shelf life to, let's say, 1 year, or some months instead of 6 as stated by the manufacturer? As I said the closed bottle was opened a month ago, I'm not sure if I diminished its potency (I couldnt find aquarium test strips to test its purity where I live, I really tried) to the extent it became unusable.
Also, there's a considerable gap between the salt and the cap, like just a tad more than the half of it.
If so, should I order another SN batch and just trust the same manufacturer and never check it this time around and put the sealed bottle in a kitchen airtight jar?
I've read that I should put the SN in an airtight container, or that I should keep it in its original bottle, some sources claimed that it couldn't be a "normal airtight kitchen jar"...
I'm afraid of asking these questions to the manufacturer and raise suspicions...
Thanks!
