No, and here's why.
First off, the FIRST layer of defense your body has against infection is the benign bacteria that reside on your skin. If you kill these bacteria, you're just opening up an environment for pathogens to thrive on, free from competition.
Second, your immune system works much, much better when there is a low level of stimulation at all times (AKA benign bacteria). This helps the immune system respond faster when there's a real infection, and it keeps your immune system from turning on itself (allergies, arthritis)
Finally, the use of antibacterial products simply promotes the development of antibiotic-resistant bacteria. Bacteria adapt VERY quickly, and if a given antibiotic is widely used (especially by untrained people who slosh it everywhere), resistant bacteria become more the norm than the exception. Antibacterial products provide a false sense of security, and make it harder for doctors to kill the problematic bugs since they have to keep developing different antibiotics. Time was, penicillin would kill pretty much everything out there. Now some bacteria are even resistant to vancomycin, commonly considered the "drug of last resort".
As for Triclosan specifically, there is some debate about whether it is safe...it may or may not be a carcinogen, for one thing.
