Our lake and dye bath bomb colorants are batch certified and are perfect colors to color bath bombs, bath salts, bubble bars, and all types of in-bath products. They also are great for coloring melt and pour soaps. Our dyes are batch certified and our mixes are made from batch certified lots. You will receive the lot and/or batch number on the label of each jar.
Nurture Soap has a batch certification account with the FDA. When we receive a lake or dye, we send it to the FDA to be tested for purity and dye load. Once the color is certified, we are allowed by the FDA to pack the colors into jars and sell our lakes and dyes to you.
Dyes are water soluble and mix in water. Lakes are oil soluble and mix with oil. Polysorbate 80 used at 2% of your total recipe is recommended when making bath bombs if your recipe contains oils. This will help disperse the oils and color in the bath.
