Great questions...
I am going to be a little vague in my response for competitive reasons. CCM Crystal Clear will handle the cold exceptionally well. It's freezing point is well below -50 degrees Celsius (that is not a typing error). I wouldn't intentionally subject it to cold weather, but it won't hurt it, it will only increase your time to heat it.
If you find this interesting you can put a cup of it in the freezer and see what happens. Odds are you already have some very similar products in your freezer. You may not notice a difference, or you may notice it slightly thicken some. It will heat right up (it just takes a little longer).
The biggest benefit is if you are fishing in cold waters. There should not be a noticeable difference in your baits action.
