I recently found out that most liquid laundry detergents and all liquid fabric softeners are made using pig fat and in some cases, cow fat. This has been a source of chagrin to some of my Jewish customers who have been using these products unawares. Just thought I'd pass along what the manufacturers don't want you to know. Stick to powdered detergent. Its better for the washer anyway and won't stink after a few loads.
