Para-phenylenediamine(PPD) was earliest traced by Hofmann in 1863. Prepared to be used in the formulation of hair dyes at the end of the 19th century and is acquired from petroleum. It is the frequent and the most familiar ingredient in hair dyes, for printing, making tattoos, gas, oil, and rubbery products. The benefits of hair dyes cannot be ignored. With growing tensions and the effects of pollution, hair tends to lose its blackness and shininess. Dyes can also be obtained by using ammonia and hydrogen peroxide but, the substance in ammonia rips apart the layers of protein from the hair making it dry, and brittle and increases in breakage of hair strands from roots and the chemicals in hydrogen peroxide bleach the hair causing it to lose its natural potential of the hair.
PPD chemicals are used in many permanent and semi-permanent hair dyes. These colouring agents help in trapping the dyes in hair and retain it for longer periods giving it a natural look. It is also a familiar allergen and irritant. The darker the dyes the higher it contains PPD chemicals. PPD is the reason for the reaction in hair dyes. PPDs are commonly found in the formulations of more than 1000 hair dyes. PPD is a chemical which is a very harsh chemical that may lead to mutagenicity, cancer and even causes coma in humans.
