Pepper foam has some qualities that make it really good, others that make it really bad.
Good:
1. Very little if any secondary contamination effects. Great for churches, hospitals, and in close quarters such as an elevator.
Bad:
1. It uses water and soap as it's carrier. The treatment for contamination is water and soap. Hence, some effectiveness is lost.
2. It takes longer to work as the foam must break down into a liquid before contamination takes place.
3. While still in the foam state, it can be wiped off and effectively thrown/flicked back at you.
