Usage Notes: Dyes may appear drab or look like the wrong color before being bloomed, and must be bloomed before being incorporated into your medium (see our blooming instructions, below). Please don't panic without testing a small portion in water!

A little goes a LONG WAY; please keep this in mind when using. Use latex or nitrile gloves and protect the surfaces you are working on, as these colors are extremely concentrated and will stain clothes, counter tops and hands.

  • Soap Usage: Stable in soap, but may bleed. Ideal for liquid soap: Simply blend the dye in water before adding to your liquid soap recipe.
  • Bath Bomb Usage: Dyes are water soluble and thus Polysorbate 80 is NOT necessary in your recipe. Sodium bicarbonate (baking soda) is alkaline and can change some colors to an unexpected color. If this happens, add a half part citric acid to your baking soda. This should balance the pH levels and give you an accurate color. Note that you can add bloomed dye to baking soda first so that you do not activate your citric acid, but we highly recommend following your bath bomb instructions for use.

How to bloom a dye: Take a small amount of dye and add enough water to dissolve the dye powder. Stir or swirl to assist dissolving. You can also add dye powder to a medium and use a spray bottle to spray water onto powder to bring out the brilliant dye color.

Love this blue

I have made two different shades of blue with this dye and it does not disappoint. I am happy with how the color turned out being that it was my first time using dyes

Amazing all the way around.

I loved every single bit of my experience ordering from Mad Micas for the first time. The colors, the speed, the customer service. I got a little giftie in my package that just sent me over the top happy. They had not idea but they gave me my favorite dum dum flavor in the world (cream soda), a card with a frog on it (also my favorite) and a sample of my favorite color Mica. My husband looked at me and said "Someone in that company must know you". LOL! It felt like it. Wonderful. Will order for sure in the near future!

Beautiful and Brilliant

The color was truly vibrant and everything that I expected for my bath bombs. When it hits the water, it was like the ocean.

Bright blue

Great color

I can get a brilliant blue color using this dye. I was unsure about it, but now I'm glad I tried this. Will be buying other colors.
