Revisited my williams puck after a long layoff this a.m. and it got me thinking exactly what is it made of. Not a bad soap but not as cushiony as a tallows like Tabac or palmolive( my two favorites) nor does it seem as slick as glycerin. So what exactly is it made out of? I'm sure this question has been answered approx.2,000 times and some are sick of it but I'm curious and couldn't find it in the first page of search results.
