November 14 Information
Sharing bar soap; hygenic?
Is sharing bar soap, like in a public bathroom, hygienic? Does the bacteria from the previous user's hands get stuck on the soap and transferred to your own hands when you use it?

Our article on
Soap suggests that the primary purpose of soap is to remove oils and grease from the skin. Some soaps contain metal particles that when rubbed against bacteria destroy the surface and, as a result, kills them. I would conclude that some bacteria does remain attached to the soap and that the metal particles do not successfully kill all the bacteria (and therefore would not recommend sharing a public bar of soap).

To follow on the question...is it more hygienic to not use soap? I would (possibly incorrectly) assume that it's better to use used-soap than no soap at all?

(ec) It's pretty much unheard of (at least in the UK) to find actual bars of soap in public facilities these days, possibly because of hygiene concerns, and also for practical reasons - what happens if the soap gets lost, falls on the floor, etc? It's
soap dispensers everywhere.

I don't think you would find bar soap in public restrooms in the US, either, except maybe in vey old ma-and-pa kinds of establishments. I do think it would depend on the type of soap. I would trust an anti-bacterial soap more than other kinds, given the alcohol content which is supposed to kill the critters off. ←

An article about the medical practices in the Us and Russia, several years ago, mentioned the likelihood of disease transmission by soap bars. Visiting US doctors were horrified to see the Russian doctors using a common bar of soap by a sink to wash their hands in the operating rooms, and a common towel to dry them.
Not the article I read, but similar. Semmelweis, in the mid 18th century, wanted doctors to rinse hands in bleach solution, likely more effective than washing with soap.

Bleach on the hands is rather nasty, and would destroy the skin in short order, leading to infections which could then be spread to others.

I expect the recommendation was to dilute the bleach to an acceptable level, but I agree that bleach is not kind to either bacteria or skin cells.

Semmelweis apparently did use a diluted bleach solution. Such a solution is still used medically, as
"Dakin's solution". See
Henry Drysdale Dakin. I saw it used on bandages applied after surgery in the 1990's. Several other more harmful chemical solutions were regularly used in skin contact in the early 20th century.

Old competitor to Waldenbooks
I am trying to find the name of a company that used to compete with Waldenbooks in the 80s and 90s that I used to shop at. It was not Borders. Waldenbooks may or may not have bought them out before Borders in turn bought Waldenbooks. I have searched the web and not been successful. I want to say the store name had initials in it like J.C. Penney does, but I may be wrong on that.

Was it
Books-A-Million? Their stores are sized and layed out much like Waldenbooks. If not, then maybe it was
B. Dalton; which was of the same type of store, and has the "Initial + last name" thing like JC Penney. If not either of those, perhaps
Category:Bookstores of the United States has some more leads. --

It's got to be B. Dalton, which had the same format as Waldenbooks and was acquired by Barnes & Noble. --

As noted in
B. Dalton, the store began in the 1960s as a subsidiary of the Dayton's department stores based in Minneapolis. In the 1980s it was sold to Barnes & Noble, which slowly phased out the B. Dalton stores over time, closing the last remaining stores a couple of years ago. ←
