INCI Name and Common References

INCI name: 2-[(4-Chloro-2-nitrophenyl)amino]ethanol Common terms: HC Yellow No 12, hair dye ingredient Nicknames: Chloronitroaniline, CNAE

Function

The ingredient 2-[(4-Chloro-2-nitrophenyl)amino]ethanol (HC Yellow No 12) and its salts act as a colorant in hair dye products. It provides a yellow color to the hair and helps to achieve the desired shade.

Science

2-[(4-Chloro-2-nitrophenyl)amino]ethanol (HC Yellow No 12) and its salts are used in hair dye products as a colorant. This ingredient works by binding to the hair shaft and forming a stable complex with the keratin protein in the hair. The physical properties of HC Yellow No 12, such as its molecular weight, solubility, and charge, allow it to penetrate the hair cuticle and deposit color molecules in the cortex of the hair. The chloro and nitro groups on the phenyl ring provide the coloration, while the amino and hydroxyl groups on the ethanol chain allow for binding to the hair protein. Overall, the physical properties of HC Yellow No 12 make it an effective and long-lasting hair dye ingredient.

Benefits

As a substance in hair dye products, 2-[(4-Chloro-2-nitrophenyl)amino]ethanol (HC Yellow No 12) and its salts do not provide any skincare benefits.

Negatives

The use of 2-[(4-Chloro-2-nitrophenyl)amino]ethanol (HC Yellow No 12) and its salts in hair dye products may cause potential side effects and sensitivities in some individuals. One of the most common side effects of using this ingredient is skin irritation, which may manifest as redness, itching, or burning sensations on the scalp or other areas of the skin that come into contact with the hair dye. In some cases, this irritation may be severe enough to cause blistering or swelling. Individuals who are sensitive or allergic to this ingredient may also experience more serious side effects, such as difficulty breathing, hives, or anaphylaxis. It is important to note that these reactions can be life-threatening and require immediate medical attention. In addition to potential side effects, there may also be interactions with other ingredients in hair dye products. For example, some hair dyes contain ammonia or hydrogen peroxide, which can increase the risk of skin irritation or allergic reactions when combined with 2-[(4-Chloro-2-nitrophenyl)amino]ethanol. Overall, it is important to be aware of the potential risks associated with using this ingredient in hair dye products. Individuals who experience any adverse reactions should discontinue use immediately and seek medical attention if necessary.

Source

2-[(4-Chloro-2-nitrophenyl)amino]ethanol (HC Yellow No 12) is a synthetic ingredient that is commonly used in hair dye products. It is derived from a chemical reaction between 4-chloro-2-nitroaniline and ethylene oxide. The resulting product is then purified and processed to create the final ingredient. While it is not a natural ingredient, it is considered safe for use in hair dye products when used in accordance with regulatory guidelines.

Safety

According to the Environmental Working Group's Skin Deep database, 2-[(4-Chloro-2-nitrophenyl)amino]ethanol (HC Yellow No 12) has a moderate hazard rating of 5 out of 10. This rating is based on concerns regarding its potential to cause skin irritation and allergic reactions. Other sources, such as the European Chemicals Agency, have also identified potential risks associated with this substance, including its classification as a skin sensitizing agent. Overall, while HC Yellow No 12 is not considered to be highly hazardous, it is important to use caution when using hair dye products that contain this ingredient. It is always recommended to read product labels carefully and follow all safety instructions provided by the manufacturer.

Sustainability

The ingredient 2-[(4-Chloro-2-nitrophenyl)amino]ethanol, also known as HC Yellow No 12, is commonly used as a substance in hair dye products. However, its environmental impact and ethical sourcing practices are a cause for concern. Firstly, the production of HC Yellow No 12 involves the use of hazardous chemicals and solvents, which can have negative impacts on the environment. These chemicals can contaminate water sources and harm aquatic life, as well as contribute to air pollution and greenhouse gas emissions. Furthermore, the disposal of hair dye products containing HC Yellow No 12 can also have negative environmental impacts. When these products are washed down the drain, the chemicals can end up in waterways and harm aquatic ecosystems. In terms of ethical sourcing practices, there is limited information available on the sourcing of HC Yellow No 12. However, it is important to note that the use of certain chemicals in the production of hair dye products can have negative impacts on the health and safety of workers involved in the manufacturing process. Overall, the use of HC Yellow No 12 in hair dye products raises concerns about its environmental impact and ethical sourcing practices. It is important for companies to prioritize the use of sustainable and ethical ingredients in their products to minimize negative impacts on the environment and workers.

Conclusion

In conclusion, HC Yellow No 12 is a synthetic ingredient commonly used in hair dye products to provide a yellow color. While it has been deemed safe for use in cosmetics by regulatory agencies, there are concerns about its potential to cause skin irritation and allergic reactions. Additionally, the production of HC Yellow No 12 may have negative environmental impacts. It is important for consumers to weigh the potential benefits of using hair dye products containing HC Yellow No 12 against the potential risks and to consider more sustainable and natural alternatives.
