1. p-Phenylenediamine (PPD)
This is an organic compound derived from aniline, which is not only used for dyeing but also for uses such as rubber antioxidant, tattoos and photographic film development. PPD is a major component in artificial dyes, and the United States Environmental Protection Agency has made several studies suggesting that there are harmful effects towards the human body. Short-term exposure to the substance can cause irritation to the eyes, dermatitis, and can even induce asthma attack. Serious and chronic exposure can lead to weight loss, and eczematoid dermatitis. In line with these adverse effects, the Center for Disease Control and Prevention listed this substance as an allergen.
Naturally secreted as a by-product of human metabolism, ammonia is a substance made up of Nitrogen and Hydrogen. You can easily distinguish ammonia whenever you urinate, the major waste product when one urinates. Ammonia is also present in hair dyes, used in order to open pores in hair shafts to speed up the dyeing process. Although this substance is important at a limited degree, there can be harmful effects once the value exceed that of the normal. One of which is the irritating odor it produces. Due to the corrosive effects of ammonia, people are cautioned not to get direct contact with the substance, chiefly the skin, eyes, mouth, respiratory tract and digestive tract. Severe exposure could lead to destruction of the organ or body part involved.
Hydrogen peroxide is an oxidizing agent in dyes, which functions with a series of oxidation of structures in order to lighten your hair. Along with ammonia, these two compounds provide a gradient of shades of hair color and is the basis for the different color available for hair dyes. The amount and type of alkaline agent used will now depend on what type of hair coloring you want to use – permanent, demi-permanent, semi-permanent, and temporary hair color.
