Given what you have just said, saying “soya-free” seems to be misleading in the same manner that this is;

Edit; Ok, on reflection they are a little different, no products actually contain asbestos in effective quantities, but your competitors might sell products containing ‘effective’ quantities of soya. So “soya-free” is a legitimate difrentiating factor. However, it still seems about as ethical as advertising “antioxidant rich” product, which, as mentioned here, you don’t do.
