Q: will these work for cold processed soap?

In the description of the product is stated the following: "Soap Making Dye: shimmering mica powder can be a great soap colorant which makes it an excellent choice for soap making, with the exception of cold process soap"...........They are very clear with "With the exception of cold process soap" I am in the process of ordering this product either for Melt and Pour soap making or Polymer Clay craft.

Q: When used in bath bombs, will this stain the tub? Or skin in soap?

I ahve used many of these packs of color for bubble bars and they have not stained my tub, my skin, or my towels. I also use polysorbate-80 in the bubble bars which helps the mica not leave a ring on the tub.
