- Benzalkonium chloride works as an antiseptic and disinfectant, while benzocaine acts as a local anesthetic.
- Benzocaine blocks nerve impulses by making it harder for sodium ions to pass through nerve cell membranes.
- This prevents the nerves from transmitting signals, leading to numbness in the area where it's applied.
