I am not sure the stuff we call soap over here is the same as it was. Looking at the ingredients of the body soap I am using it contains what they call soap(sodium tallowate, sodium cocoate, sodium palm kernelate, sodium palmate) then this other stuff: water, glycerin, coconut acid, palm acid, tallow acid, palm kernel acid, vitamin E, Kiwi fruit juice however you get that, and Mango juice, so some of this may being used to adjust the Ph.
I tried body wash but the stuff never seems like it rinses off. My skin feels as if it is coated in silicone or something.
I also use soap from a local maker a 7 streets away. It contains coconut oil, olive oil, safflower seed oil, vegetable glycerin, propylene glycol, water, sorbitol sodium oleate, soybean protein, shea butter. This stuff cleans well enough and my skin feels great even better is the fragrance - moroccan cedar. Love this stuff.
So perhaps we are using things and calling them soap but they are not the same as they were years ago.
