I bought 2 new pucks of dr harris and I have read on this forum that the tallow soaps were reformulated. No, they still contain tallow. The new formulation I believe has tallow as the FIRST ingredient versus potassium palmate being the first ingredient in the older formulation. The older formulation had tallow as the 2nd ingredient. anyways, I got a new puck of arlington and windsor. Arlington refill puck had tallow as the first ingredient and the windsor had potassium palmate as the first ingredient and tallow as the second. this is probably a dumb question, but is there any difference between the formulations for those that have used the older and new formulations of the dr harris tallow soaps? do you think dr harris and others like mwf will ever drop tallow from their shave soaps and move to vegetable based like others have done? I think if it ain't broke, don't fix it.
