Wow, Phisohex(Hexachlorophene) - my sisters used bottles of the stuff.
I never knew it was very closely related to 2,4-D.  That is the most
widely used herbicide in the world!
I learned something new today.  Thanks.

Subject: Re: Hand Sanitizer and PCB Assembly

I found this:

The Center for Disease Control and Prevention (CDC) and World Health
Organization (WHO) recommends healthcare workers using an alcohol-based
hand sanitizer to disinfect hands. Using 60-95% alcohol (by weight) rub
or gel has the highest efficacy rate in killing a broad range of
microorganisms.

So hand sanitizers have their place.  People have been sanitizing for
millennia with soap, i.e. potassium and sodium salts of fatty acids,
without soap becoming less effective at removing germs, Additionally,
ethanol has been used for sanitizing for well over a century without
losing its basic effectiveness.

However, my mother washed my baby brother every day with Phisohex when
he was an infant, when it would have been much better to use a mild,
super-fatted soap.  She did this because she had an exaggerated fear of
germs.  This did not prevent him from pulling a piece of chewing gum out
of the sandbox in a public park, which resulted in the whole family
having dysentery.
