I Just finally used this in some Halloween soaps. I'm obsessed. So neat!
This is an amazing product and so fun. I made M&P snowflake and used them on top of my cold process soap. I call it Glowflake. :-). The blue glow powder worked perfectly!
This looks so good in my embeds. I don't necessarily recommend adding it directly to CP soap unless you use a LOT, but I put it in a clear melt and pour to embed in my CP soap and the glow is amazing and sticks around for a while.
I must say buy the blue and buy the green together. They both give off a beautiful glow in the dark. Easy to use product. Really nice with CP and M&P.
When I use it in uncolored soap batter (at the recommended usage amount), the results are spectacular! It's definitely stronger when you don't use additional colorants with it. I created a Halloween soap with big swirls of uncolored batter with lots of this mixed in, and it's really a showstopper.
