If odor levels can be brought down to a point that is undetectable or is so low, that it does not trigger an alarm for the animal, it results in not spooking the animal. Scent Killer was found to be over 99% effective at stopping replicated human odor in testing at Rutgers University.
Scent Killer kills human scent on contact, at the molecular level. It keeps human odor from forming a gas. When the human odor doesn't form a gas there is no smell. Scent Killer is totally odorless when you first put it on and keeps you odorless even after it dries. A must for big game hunters.
