"WOW! - Oh my goodness I am in love!! ... customers love the affect it has on their water! Very impressed."
-- Samantha V. (verified buyer)

Some super nice copy that describes the color blue, that it's FD&C analyzed and certified, and that it's a high dye load.

Dyes must be bloomed before use! Dyes can appear drab or even look like the wrong color before being bloomed. Please don't panic without testing a small portion in water! (Blooming instructions below)

Additional Information:

  • Soap Usage: Dyes are stable in soap, but may bleed. However, they are ideal for liquid soap: Simply bloom the dye in water before adding to your liquid soap recipe.
  • Bath Bomb Usage: 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.
