    1. Great color in cp soap 4 star review

      Posted by on

      Works very well in my cp salt soap. A little goes a long way to make a rich blue color. I was worried for a while because when the soap first came out of the mold, it smelled like sulphur/rotten eggs. My soap only contained coconut & castor oil, salt, lye, and water. The smell faded after a few days - I'll have to do a lather test when the soap cures to make sure the smell doesn't return when wet. If it doesn't smell, I'm golden.

    2. A little goes a long way! 4 star review

      The tiniest amount gives soaps a gray hue, a little more results in sky blue at around 1/8 tsp per pound of oils. Very economical!

    4. NOT FOR BATH BOMBS!! 3 star review

      Posted by on

      Wish that would have been made more clear before I ordered and mixed with my bath bomb mixture. Wasted a whole batch and stunk up the house. Yuck!

      Pretty color though. I’ll save it for soap

    5. Reacts with Citric Acid. DO NOT USE IN BATH BOMBS. IT WILL STINK OUT YOUR HOUSE! 3 star review

      Posted by on

      I bought this to use in melt and pour soap and bath bombs. How I missed the review below where it said not to use in Bath Bombs... I don't know, I am kicking myself.

      I made bath bombs and used a bit of this pigment powder. Oh My Days... this gave off such a bad scent straight away.

      I contacted BULK Apothecary only to be told oxide powders react with citric acid, hence the smell. They need to update this information on the website ASAP!

      Learning how to use oxide powder, I decided to purchase this product as my experiment and I am Beyond Happy! Use a little for a Gorgeous sweet blue or a lot for a Beautiful dark almost sometimes navy! Will be purchasing again when needed!

    7. Great Product 5 star review

      I used it for melt and pour glycerine soap and I couldn't believe how beautiful the color came out. Be aware that it doesn't take much to achieve a deep, lovely blue. I can't wait to use the yellow I also ordered.

    8. Matte cobalt blue mica. 5 star review

      Beautiful color. Easy to use and it doesn't change hue in both cold or hot process soap.

    9. Great coloring 5 star review

      Posted by on

      I initially purchased the sample color packet and used the color in there. I just got this color in the 2 oz package and you definitely get your money's worth here. This will go a long way for sure!
