Review on 18 Color Mica Powder: Cosmetic Grade Pigment for DIY Slime, Epoxy Resin, Nail Art, and more! by Heather Shaw

I have used these to make soap, they are fantastic and give vibrant results. But now that I'm preparing to make soap for sale and compiling my ingredient list, I've had to stop using mica and use another supplier who lists the ingredients on their packaging so I can properly label my soap. Glimmer for example. and titanium dioxide is the basis of mica dyes, but I need to know if they contain iron oxide, ultramarine blue, etc. I wish I didn't have this problem because I really enjoyed using them. However, if I don't know what's in it, I can't properly tell the users of my future soap what's in my soap. The picture is a batch of soap I made using these mica colors.
