In a typical household, the following surfactants are found, among others:
- Soap / handwash
- Shower gel
- Dishwashing agent
- Washing powder / liquid
From my understanding, the role of all these is to lower the surface tension between water and fatty acids, enabling one to "wash" things.
Are they all the same then, and is the only difference between them marketing? Can I wash my hair with dishwashing agent, or pour shower gel into my washing machine?
