Simply washing our hands with soap it turns out is the best way of removing harmful germs from ourselves and our environment.
Of course hand sanitizers do the job as well and they are conveniently packaged so that we can clean our hands on the go. There is not always water and sink and soap available.
Antibacterial Soaps for household use generally contain an active ingredient triclosan or triclocarban at lower concentrations .1% and .45%. Community based studies have shown that triclosan and triclocarban in these low concentrations, are generally no more effective than plain soap.

So no real upside to the antibacterial products, there is a downside though that requires consideration. Triclosan works in a similar way to the antibiotic isoniazid, which has raised the question of whether widespread community use of triclosan may play a role in the development of antibiotic-resistant bacteria. Several laboratory-based studies have supported this theory, while community-based studies have not demonstrated evidence of antibiotic resistance with the use of triclosan-containing soap over a one-year period.
Further research is needed in this area.
Other concerns include the potential of triclosan to react with chlorine in tap water to form chloroform gas (a potential human carcinogen) and dioxins (harmful to the human endocrine system and the environment). The actual risks posed by these reactions, outside the laboratory setting, are currently unclear.
In 2017 the US Federal Drug Administration ( FDA ) prevented the use of Triclosan in hand sanitizers and antibacterial soap products.
These types of unnecessary chemicals add to the cocktail that we are inadvertently exposed every day. This constant exposure adds to the body's “toxic burden”.
This toxic body burden is the EWG’s (Environmental Working Groups) chief concern about household chemicals. Our daily or weekly exposure over a lifetime of what seems like innocuous chemicals can build up enough or cause enough harm in your body that it triggers some kind of disease outcome. The concept [of body burden] is that pollution is not just in our air and in our water — it’s also in us.”

Endocrine disruptors like BPA and phthalates lurk in everything from cleaning products to fragrances. Our bodies are run by a network of hormones and glands (the endocrine system) that regulate everything we do.
