Para red, also known as para-phenylendiamine (PPD), is an organic compound commonly used as a dye and in hair coloring products. Its mechanism involves the oxidation of the amine groups in the presence of an oxidizing agent, leading to the formation of colored azo compounds. These azo compounds result in the vibrant red color associated with para red. Additionally, the compound can undergo polymerization, contributing to the stability of the dye in various applications.
Azo food dyes don't set off allergic reactions as such, though some azo textile dyes can cause your skin to be hypersensitive. The mechanism for why tartrazine increases allergic reactions is not yet known.

To prepare para red dye, you typically start by dissolving a suitable dye precursor, such as para-phenylenediamine (PPD), in a solvent like water or alcohol. Next, mix in an acid, such as hydrochloric acid, to facilitate the dyeing process. The solution is then heated to enhance color development. Always follow safety guidelines, as the chemicals involved can be hazardous.
