I took out one of my 120ml. bottles of nicotine for mixing, but I only want to take 30mls. out of the bottle. Can I refreeze the nicotine after taking some out of the bottle? I don't mix a lot, and don't need that much out at a time. It's VG based and letting it thaw before taking some out because it's so thick and need to be able to shake it up. It's going to leave air space in the bottle and whether I refreeze it or not, it's going to a while before using it up and would rather have it back in the freezer.
