Is CI 16035 (Red 40 / Allura Red) banned?
CI 16035 (Red 40 / Allura Red) is permitted by the US FDA. Several countries restrict, warning-label, or have reviewed it for safety concerns. The US has more lenient additive rules than the EU, UK, Canada, and Japan, which is why this ingredient remains widely used here.
Why CI 16035 (Red 40 / Allura Red) is flagged
Topical cosmetic use of CI 16035 is considered safe. Systemic absorption from properly formulated rinse-off or leave-on products is minimal. Unlike food consumption (where concerns include potential behavioral effects in hyperactive children), topical cosmetic exposure does not raise the same issues. The CIR and FDA have assessed it as safe for cosmetic use. It is not a carcinogen for topical applications.
