HYDROXYPROPYL BIS(N-HYDROXYETHYL-P-PHENYLENEDIAMINE) HCL

Description

Hydroxypropyl Bis(N-Hydroxyethyl-p-Phenylenediamine) HCl is a synthetic hair dye ingredient primarily used in permanent hair coloring products. This compound belongs to the family of phenylenediamine derivatives, known for their ability to produce long-lasting color results. The chemical structure of this ingredient allows it to penetrate the hair shaft effectively, where it reacts with an oxidizing agent to create larger color molecules that cannot easily wash out.

This hair dye precursor is particularly effective in producing cool-toned shades, ranging from ash blondes to deep blues and violets. It offers excellent gray coverage and color stability, resisting fading from washing and environmental factors. The addition of hydroxypropyl and hydroxyethyl groups to the molecule enhances its solubility and helps reduce potential skin irritation compared to some traditional hair dye ingredients.

When used in hair coloring formulations, Hydroxypropyl Bis(N-Hydroxyethyl-p-Phenylenediamine) HCl is typically combined with other dye precursors and developers to achieve a wide range of color results. It is important to note that, like all oxidative hair dyes, this ingredient should be used with caution and according to manufacturer instructions to minimize the risk of allergic reactions or skin sensitization.
