my research on the webs indicates that SunScreen degrades in heat fairly quickly.... The degradation happens because:
1.the emulsion that is the sunscreen fails - separates and gets runny, and
2. heat breaks down the active component in sunscreen....
This makes sense, as a pharmacist, we have data on stability of different drugs at different temperatures,,, Generally, at room temperature they will get a certain dating, possibly in a fridge gets a longer dating..... Liquids and emulsions get the worse dating....
Looking at getting a small container that can clip to the key ring, that way, it's not stored in the car...
Also looking at a long sleeve sun shirt to tuck in the pocket behind the seat (similar to what the fishing guys use on YouTube), as well as a ball cap with the extra drape to cover the back of the neck....
