I've seen alotof info/questioning about what occurs if a transdermal is refrigerated, frozen etc, mainly relating to keeping its potency. I'm wondering the opposite way. What happens if a PH transdermal is heated. Nothing outrageous, but kept in say a car during a hot day. It certainly makes the solution much more runny, but will this degrade the actual PH in anyway? I'm not looking to store anything in the car long term, just for a day or two while on a road trip (no A/C).
