Facts

• In foam pepper spray, the pepper spray solution squirts out like shaving cream, expanding on contact.
  
  

Effects

• Foam pepper spray causes tearing eyes, runny nose, excessive coughing and difficulty breathing. Its effects are enough to incapacitate an assailant, allowing time to escape or receive help.
  
  

Significance

• Foam pepper spray expands and sticks to the target's face on impact. Attempting to wipe away the foam only grinds the pepper into the eyes and intensifies the burning sensation.
  
  

Benefits

• Unlike its liquid counterpart, foam pepper spray is heavy enough to eliminate potential wind "blow back," limiting the chances for self-injury. The foam is also easier to see when squirted, improving accuracy.
