Science
Mechanism of Action
CI 16035 functions by providing a red pigment to cosmetic formulations, thereby coloring the product itself, as well as skin, nails, or hair upon application. It is an azo dye, and while primarily a colorant, it can also act as an excipient in fragrance oils.

Stability

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) deems CI 16035 (Allura Red AC) safe for cosmetic use. The EU's Scientific Committee on Consumer Safety (SCCS) lists it as an approved coloring agent without general use restrictions, except for non-oxidative hair dye products where a maximum concentration of 0.4% applies, and it is prohibited for dyeing eyelashes and eyebrows. The US FDA has permanently listed FD&C Red No. 40 (CI 16035), requiring certification and generally permitting its use in cosmetics, with the exception of the eye area unless in its aluminum lake form. The ingredient should be protected from oxidizing or reducing agents.
