- TL;DR Summary
- more specifically, the use of shaving soaps and making and using lather
(This topic might be better placed in a different board or subforum)
I would guess that some companies or scientific education departments actually study the production, use, and properties of foam, like what wet shavers do for making lather from shaving soaps in order to conduct a wet-shave. I have not seen (online) any such discussion to include concentration of a lather, volume, ratio of soap product to water, lubricity, lather stability, extent of wetting of the hair. This is either part of chemical engineering, or cosmetology, or ? 'cosmetic science'. Maybe for the field of barbering. (?) I would guess that most people doing a shave at home do not care.
