Stabilizing, using an ingredient bonding agent and the right amount of antifreeze will compliment a product. Antifreeze such as glycerin / p. glycol serves to not only help guard against freezing but also retards the evaporation / dry out of your product. So when building a product you need to consider all the zones that your product will be used and to base your formula on such information. Basically you have to prepare for some of the worse case scenarios also.
Your base material is a big part of that building process particularly in lure development. Very cold temps can constrict the odor output simply due to the environmental conditions. Many of us don't deal with extreme cold, but there are trappers that work in and thru extreme cold most of their season.
As a trapper first, I prefer to have a product that is workable and may thicken to some degree due to very cold temps, but not to freeze extremely hard. As a formulator I know the benefits of using antifreeze in every lure that is made. If working some extended cold periods the urine and bait gets a blending of antifreeze as well. Putting out some LDC certainly helps in these cold spells as well..
Keeping a small amount of material such as lure, from completely freezing, will certainly improve its ability to release its odor base agents much better. Animals have a very keen sense of smell as we all know, so building some safeguards into a product are just a good practice and will help enhance a products effectiveness.
