1,3-BIS-(2,4-DIAMINOPHENOXY) PROPANE HCL 

Description

1,3-Bis-(2,4-diaminophenoxy) propane HCl is a synthetic compound primarily used in hair coloring formulations. This versatile ingredient functions as a coupler in oxidative hair dyes, playing a crucial role in the development of color when combined with primary intermediates and an oxidizing agent. Its chemical structure allows for the creation of a wide range of hair color shades, particularly in the brown and red spectrums.

The compound is water-soluble, which facilitates its incorporation into various hair dye formulations, including creams, gels, and liquids. Its stability in alkaline environments makes it compatible with the typical pH range of hair colorants. When used in hair dye products, 1,3-Bis-(2,4-diaminophenoxy) propane HCl contributes to color longevity and helps achieve more natural-looking results.

Safety assessments have shown that this ingredient, when used at appropriate concentrations in hair dye formulations, poses minimal risk to consumers. However, as with all hair dye components, patch testing is recommended to check for potential allergic reactions. Professional colorists often prefer products containing this coupler due to its reliability in producing consistent color outcomes across different hair types and conditions.
