If you want a nice mold in cubes, go to AC Moore or Michaels and get the Wilton mold it has 24 mini squares for about $10. I love it for sugar cubes. I think the reason for the e-wax is to make it firm, Shea to help harden & to help moisturize, Vit. E to help with oxidation & Poly 20 I forget for sure why but it might help with suds. HTH Carol
