SUMMARY

The discussion centers on the technical and cosmetic studies of foam, particularly in the context of wet shaving. Key factors such as lather concentration, volume, soap-to-water ratio, lubricity, lather stability, and hair wetting are identified as critical components in the formulation of effective shaving lather. The conversation suggests that these aspects fall under the domains of chemical engineering, cosmetology, and cosmetic science, although there is a noted lack of comprehensive online discussions on the topic. The relevance of colloidal suspensions in the formulation of shaving creams is highlighted as an area for further exploration.

PREREQUISITES
  • Understanding of colloidal suspensions
  • Knowledge of chemical engineering principles
  • Familiarity with cosmetic science
  • Basic concepts of lather properties in shaving
NEXT STEPS
  • Research the properties of colloidal suspensions in cosmetic formulations
  • Explore the principles of chemical engineering as they apply to foam production
  • Study the effects of soap-to-water ratios on lather performance
  • Investigate the role of lubricity and stability in shaving products
USEFUL FOR

Cosmetic scientists, chemical engineers, wet shaving enthusiasts, and anyone involved in the formulation or study of shaving products will benefit from this discussion.

TL;DR
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.
