I ordered a lavender refill puck and noticed that the ingriedients on the back changed some. It's still tallow as the first ingriedient, but now it has potassium laurate and sodium laurate in it as well. I have 2 other refill pucks I bought a few months ago from maggards, the arlington and windsor and they both don't have potassium and sodium laurate in them, so I am wondering if the lavender refill puck I got is the a new formulation of dr harris? anyone have dr harris refill pucks with potassium/sodium laurate in them?
