2-HYDROXYETHYLAMINO-5-NITROANISOLE

Description

2-Hydroxyethylamino-5-nitroanisole is a synthetic hair dye ingredient primarily used in semi-permanent and temporary hair coloring products. This compound belongs to the nitro dye family and is known for its ability to impart vibrant red to purple hues to hair. Its chemical structure allows for effective penetration into the hair shaft, resulting in longer-lasting color compared to some other temporary dyes.

The ingredient works by interacting with the hair's keratin structure, depositing color molecules without significantly altering the hair's natural pigment. It is often combined with other dye compounds to achieve a wide range of color results. 2-Hydroxyethylamino-5-nitroanisole is particularly effective on pre-lightened or naturally light hair.

While generally considered safe for use in hair dye formulations, this ingredient may cause allergic reactions in some individuals. Patch testing is recommended before use. It is important to note that 2-hydroxyethylamino-5-nitroanisole is not approved for use in the European Union due to concerns about its potential carcinogenicity. In regions where it is permitted, its concentration in hair dye products is typically regulated to ensure safety.
