D&C Red No. 6 is an excipient (pharmacologically inactive substance). It is FDA-approved, high-purity pigment. It can be tinted with titanium dioxide to create light red/pink shades. The color additive D&C Red No. 6 is principally the disodium salt of 3-hydroxy-4-[(4-methyl-2-sulfophenyl)azo]-2-naphthalenecarboxylic acid. To manufacture the additive, 2-amino-5-methylbenzenesulfonic acid is diazotized with hydrochloric acid and sodium nitrite. The diazo compound is coupled in alkaline medium with 3-hydroxy-2-naphthalenecarboxylic acid. The resulting dye precipitates as the disodium salt. D&C Red No. 6 is used in decorative cosmetic products including lipsticks, nail lacquers & face makeup (in USA prohibited for eye makeup), personal care products, soaps.
