What is the physical (or chemical) mechanism by which soap (liquid and/or bar) cleans you?

I always assumed it has something to do with the foam, but I’m not quite sure what.

I also assume that shampoo and toothpaste work in a similar way, but with different chemicals that provide specific benefits to hair and teeth respectively.

Soap is an emulsifier which means it makes oil soluble in water and this is what makes you clean
It doesn’t need to foam
