Cuticura soap
Appearance
Cuticura soap is an antibacterial medicated soap that uses trilocarban instead of the normal triclosan. These two antibacterial agents are very similar molecularly. By themselves they kill 99.99% of bacteria and microbes (like fungus spores) on contact. However when used as a soap additive triclosan has not proven to kill any more bacteria than normal generic soap.
Cuticura soap however has had a strong but smaller following and his been in use, relatively unchanged since 1865.
