Five Ways to Use Milk Powders in Bath & Body Products

To be honest, the only thing that I have made with a milk product in it was a milk bath and that was in a powdered form.  I have not really looked into making other products with milk but after looking at this posting from The Natural Beauty Workshop called Five Ways to Use Milk Powders in Bath and Body Products , I am reconsidering using milk powder in other products.  After reading this posting I am considering using milk powder in bath truffles and bath bombs.  What about you?
