I ended up putting mine in the freezer by mistake which might mean it's no longer dependable. That's why I'm going to watch this discussion to see various thoughts on the matter.
Uncertain if this belongs in the supplies section or elsewhere. Many people including myself figured that since it's suitable for medications it should work for my solution too so I considered keeping it cool. However the producer indicates it ought to stay at ambient temperature does the group here hold a different view. There's also that common online tactic of giving incorrect info to draw out accurate details. I recall some explanation involving science where the preservative works better against microbes at normal temperatures than when chilled. If I'm misstating this please correct me. Assuming it's accurate how much do the compounds react to ordinary warmth after mixing. It seems logical that very high temperatures harm them while cooler conditions might help preservation yet the makers state the preparation remains stable for several weeks at room conditions. Considering that chilling it to extend the life of the active ingredients might increase chances of contamination instead. Since few of us operate in sterile environments and typically finish a container within weeks perhaps avoiding bacteria is more important. Still maybe the lower temperature reduces any surviving microbes activity more than the reduced preservative power matters. The official source probably has it right though. This might be overthinking it but interest got the better of me. What really bothers me is folks opting for inexpensive imported mixing liquid when the reputable version adds only a tiny fraction to the overall expense yet provides much more assurance of quality. We're taking enough chances as it is with the main product. And if someone accuses me of promoting a company using plain sterile liquid for one time portions is perfectly acceptable to me feel free to disregard everything above.
