What Is Red 33 Lake?
Red 33 lake is a synthetic pigment used to add color to makeup, as well as skin care and drugs. The term lake refers to the process of transforming a pigment from a solid to a solution, usually using a metallic salt. This makes it insoluble in water.
Another name for this colorant is D&C Red No. 33 Aluminum Lake, with the “D&C” designation meaning it’s approved for use in drugs and cosmetics.
The United States Food and Drug Administration has ruled Red 33 lake safe in its current use.
