Freebase should allways be clear. I've had it stored in my freezer since the great nicotine panic of 2017 and it's still flavourless and clear.
Can't say the same for the newer bottles of 72mg nicotine salt I've bought but I've allways been told the salicylic or benzoate added causes this.
Same here....have a bottle of 200mg/ml, glass bottle, in the freezer since 2018 and it's perfectly clear. In a PG base.
PG with time will change color and turn yellowish.
