2-Nitro-p-phenylenediamine dihydrochloride is a hair dye ingredient that plays a crucial role in cosmetic formulation. It is used as a colorant to impart a dark brown or black color to hair. This ingredient works by penetrating the hair shaft and reacting with the melanin present in the hair to produce a permanent color. It is also used in combination with other hair dye ingredients to achieve a desired shade and to improve the stability and longevity of the color. However, it is important to note that this ingredient can cause skin irritation and allergic reactions in some individuals, and therefore, its use in cosmetic formulations is regulated by various authorities.
2-Nitro-p-phenylenediamine dihydrochloride is a chemical compound with a molecular formula of C6H7N3O2·2HCl. It is commonly used as a hair dye ingredient due to its ability to react with the proteins in hair and form a stable, colored complex. This reaction occurs due to the presence of the nitro group (-NO2) and the phenylenediamine group (-NH2) in the molecule, which are both highly reactive and can form covalent bonds with the amino acids in hair proteins. The dihydrochloride salt form of the compound enhances its solubility in water, making it easier to apply to hair. However, it is important to note that this ingredient can cause skin irritation and allergic reactions in some individuals, and its use should be carefully monitored.

2-Nitro-p-phenylenediamine dihydrochloride is a synthetic ingredient that is derived from coal tar. It is commonly used as a hair dye and is also found in some cosmetic products. The processing pathway for this ingredient involves the nitration of p-phenylenediamine followed by reduction to produce 2-nitro-p-phenylenediamine. This compound is then reacted with hydrochloric acid to produce the dihydrochloride salt form.
The safety rating score for 2-NITRO-P-PHENYLENEDIAMINE DIHYDROCHLORIDE varies depending on the rating system used. According to the Environmental Working Group's Skin Deep database, this ingredient has a score of 7 out of 10, which indicates a moderate hazard. It is classified as a skin irritant and sensitizer, and there is limited data on its potential to cause cancer or developmental toxicity. Other sources, such as the European Chemicals Agency (ECHA), also classify 2-NITRO-P-PHENYLENEDIAMINE DIHYDROCHLORIDE as a skin irritant and sensitizer. The ECHA has assigned it a hazard statement of H317, which means it may cause an allergic skin reaction. Overall, it is important to use caution when using products containing 2-NITRO-P-PHENYLENEDIAMINE DIHYDROCHLORIDE and to follow any safety instructions provided by the manufacturer. It is also recommended to consult with a healthcare professional if you have any concerns about the safety of this ingredient.
2-Nitro-p-phenylenediamine dihydrochloride is a chemical compound that is commonly used as a hair dye. Unfortunately, this ingredient has a significant environmental impact due to its potential to contaminate water sources. When 2-nitro-p-phenylenediamine dihydrochloride is washed out of hair, it can enter the water supply and harm aquatic life. Additionally, the production of this ingredient can contribute to air pollution and greenhouse gas emissions. In terms of ethical sourcing practices, it is important to note that 2-nitro-p-phenylenediamine dihydrochloride is often derived from coal tar, which is a byproduct of the coal industry.
