I use nellies for all my laundry including diapers and my kids have crazy sensitive skin and we have had no bad reactions. We have soft water. I love Nellies and their oxygen brightener is great too, but pricey . I have the giant tub of Nellies that I ordered through cotton babies, the brightener doesn't come in bulk though.
