HC YELLOW NO. 17.

Avoid CAS 1450801-55-4 / HAIR DYEING

HC Yellow No. 17 is a synthetic organic compound primarily utilized as a direct non-oxidative hair dye. It functions by adhering to the hair shaft surface to impart a yellow color, with its effects typically lasting for one to two washes. While deemed safe at concentrations up to 0.5% for hair coloring, it is classified as a strong sensitizer.

Summary

Hair Dyeing

Science

Mechanism of Action

Operating exclusively as a hair colorant, HC Yellow No. 17 functions as a direct dye. It selectively adheres to the exterior of the hair shaft, depositing color without undergoing chemical reactions often associated with oxidative dyeing systems. It exhibits no known biological or cosmetic activity beneficial to skin when topically applied.

The Scientific Committee on Consumer Safety (SCCS) has evaluated HC Yellow No. 17, deeming it safe for use in non-oxidative hair coloring products at concentrations up to 0.5%, with the crucial caveat that it is considered a strong sensitizer. There is no specific review by the Cosmetic Ingredient Review (CIR) or definitive status from the FDA available for this compound, although the FDA generally advises caution and patch testing for 'coal tar' hair dyes due to potential sensitization.
