Review on 🌈 Vibrant Bath Bomb Soap Dye - 20 Colors | Wayin Food Grade Skin Safe Liquid Colorant | Concentrated Neon Soap Coloring for Soap Making DIY Bath Bomb Kit, Bath Salt Crafting, Slime, Clay by Denise Davis

I really like that they are very concentrated but. When I washed my hands with the soap I made with one of the blue ones, I noticed that bubbles/suds were also blue but washed off and didn't stain my hands. The only real downside is that dark colors turn your bubbles and foam into that color when you use them. It doesn't smell, which is also a good thing. I probably won't buy again based on what I've listed. I don't want people there to wash their hands or body for fear it will soil their skin.
