What's so great about it? I went to the web site where it's sold and they mention that it's one of the few 'pure' soaps that are still made today. That's all fine and dandy, but what makes it so good for laundry? Could you substitute your own homemade 'pure' soap in the laundry soap recipes I've found on other threads? Why or why not? Someone somewhere mentioned it's smell. Does that mean it has some kind of fragrance added?
