OK, it's not just one thing that is doing this, there are numerous additives we and vendors are using that are put into juices that are effecting the final outcome of storing in plastics. Simple solution is to just use glass and not even worry about it. Same with buying pre-made juices, if your buying from vendors who are putting your juice in 15-30 and up ml bottles then I would consider asking them to use glass or simply dont buy it. By the time they mix it up and you get your juice even 3-5 days later it could be effected using plastic bottles. I've done enough testing now with many different flavorings and have tried mixes only 2-4 days old as well as longer steeped juice in plastic vs Glass,,,, the Glass wins every single time, it just taste better.
I just found two bottles of a sour Apple and a cinnamon from a year ago and the bottles have actually changed in color to a yellow and a red-ish,, that is pretty sick. Of course those 2 flavorings are well known for having a reaction to tanks and plastic but still, to think I vaped some of that isnt fun,,, in fact I got sick of using it not to long after I bought it because I thought it tasted funny,,, so while looking through some old stuff I came upon them, dam there really sick looking.
