What Are FD&C Dyes And Lakes (and how do they differ)?

Posted by Brad Schmidt on

Note: ALL of Mad Mica's dyes and lakes are FDA batch-certified.

DYE is a chemical that exhibits coloring power when dissolved. Dyes are water soluble, and will not mix with oils.  You do not need polysorbate 80 in your mix for the color to disperse and color the water.

An ALUMINUM LAKE is an insoluble material that tints by dispersion. Lakes are produced from the FD&C dyes, are oil-dispersible, and can be mixed with oils and fats.

When you use a lake (or a mica, for that matter) in a bath bomb, you must use polysorbate 80 to prevent the powder from floating to the surface of the tub water. Polysorbate 80 will allow the color to properly disperse and be evenly distributed.

Lakes are produced in specific concentrations of the Dye used. Most are available in Low Dye (10-17% pure dye) and High Dye (36-42% pure dye).  See individual product pages for specific dye loads.

DYES AND LAKES are both used for multiple applications, including bath bombs.  We have just created a collection of products specifically for the Bath Bomb maker so that it is easy to find all body-safe bath bomb supplies in one place.
