I've recently ventured into making bath bombs and bubble bars. I really wanted them to color the water, and this blue dye fits the bill perfectly! I've mixed it with other water-soluble dyes to make gorgeous greens and purples as well.
This is exactly what I needed for my bath products and the colour is stunning even after its dispersed in the water.
True to color
I bought this about a month ago, and have used it to make several kinds of bath bombs. You only need a tiny bit to make a whole tub a brilliant blue color. Definitely recommend!
I've been experimenting with a few of these dyes for the past few weeks and I was surprised how little is needed to give amazing color. Definitely a bit of a learning curve, but once you get it down - WOW
