2-HEXYLOXYCARBONYL-P-PHENYLENEDIAMINE HCL

Description

2-Hexyloxycarbonyl-p-phenylenediamine HCL is a synthetic hair dye ingredient primarily used in oxidative hair coloring formulations. This compound belongs to the para-phenylenediamine (PPD) family, which is known for its excellent color-depositing properties and durability. The addition of the hexyloxycarbonyl group enhances the molecule's stability and reduces its potential for skin sensitization compared to traditional PPD.

In hair coloring applications, this ingredient acts as a precursor, reacting with an oxidizing agent to form larger, color-producing molecules within the hair shaft. This process results in long-lasting, vibrant color that resists fading and washing. The HCL (hydrochloride) form improves the ingredient's solubility in aqueous formulations, facilitating its incorporation into various hair dye products.

While 2-Hexyloxycarbonyl-p-phenylenediamine HCL offers improved safety compared to standard PPD, it may still cause allergic reactions in some individuals. Patch testing is recommended before use. This ingredient is typically found in professional-grade hair coloring products and is particularly effective in covering gray hair and achieving dark shades. Its use is regulated by cosmetic authorities to ensure safety in hair dye formulations.
