Blue 2 Lake
FD&C Blue No.2, commonly added to tablets and capsules; also used in ice cream, sweets, baked goods, confectionary, biscuits, synthetic coal tar derivative; may cause nausea, vomiting, high blood pressure, skin rashes, breathing problems and other allergic reactions. Banned in Norway. The largest study suggested, but did not prove, that this dye caused brain tumors in male mice. The FDA concluded that there is "reasonable certainty of no harm." A lake is a solid, non water soluble form of a dye. It's produced by mixing the dye with Aluminum Hydroxide. By itself Aluminum Hydroxide is a safe food ingredient and it's often sold as an antacid. When combined with Dye, the chemicals form a deep powder that can be applied to the outsides of tablets, gumballs and other solids. You may also notice this form listed in the ingredients as "Aluminum Lake"
