INCI Name and Common References

INCI name: 2-Amino-5-nitrophenol Common terms: Amino-5-nitrophenol Nicknames: ANP

Function

2-Amino-5-nitrophenol is a hair dye ingredient that plays a crucial role in cosmetic formulation. It is used to provide color to hair and is often combined with other hair dye ingredients to create a desired shade. This ingredient is also known for its ability to penetrate the hair shaft, which allows for long-lasting color. Additionally, 2-Amino-5-nitrophenol can help to improve the overall texture and shine of hair, making it a popular ingredient in hair care products.

Science

2-Amino-5-nitrophenol is a chemical compound with a yellow crystalline appearance. It works as a pH indicator due to its physical properties. The amino group (-NH2) and nitro group (-NO2) present in the molecule can donate and withdraw electrons, respectively. This property makes it sensitive to changes in pH levels. At a low pH, the amino group is protonated, and the compound appears yellow. At a high pH, the amino group loses its proton, and the compound becomes colorless. Therefore, 2-Amino-5-nitrophenol is used as a pH indicator in various chemical reactions and analytical procedures.

Benefits

There is limited information available on the skincare benefits of 2-Amino-5-nitrophenol. It is primarily used as a hair dye intermediate and has not been extensively studied for its effects on skin. It is important to note that any skincare product containing this ingredient should be used with caution and under the guidance of a healthcare professional.

Negatives

2-Amino-5-nitrophenol is a chemical compound that is commonly used in the manufacturing of hair dyes. While it is generally considered safe for use in hair dyes, there are some potential side effects, sensitivities, and interactions that should be considered. One of the main side effects of 2-Amino-5-nitrophenol is skin irritation. This can occur if the hair dye containing this ingredient comes into contact with the skin. Symptoms of skin irritation may include redness, itching, and swelling. In some cases, skin irritation may be severe enough to cause blistering or other skin damage. Another potential side effect of 2-Amino-5-nitrophenol is allergic reactions. Some people may be sensitive to this ingredient and may experience an allergic reaction when using hair dyes that contain it. Symptoms of an allergic reaction may include itching, hives, swelling, and difficulty breathing. In severe cases, an allergic reaction can be life-threatening. There are also some potential interactions with other ingredients that may be found in hair dyes. For example, some hair dyes may contain other chemicals that can react with 2-Amino-5-nitrophenol to produce harmful byproducts. Additionally, some people may be more sensitive to certain ingredients in hair dyes, which can increase the risk of side effects or allergic reactions. Overall, while 2-Amino-5-nitrophenol is generally considered safe for use in hair dyes, it is important to be aware of the potential side effects, sensitivities, and interactions that may occur. If you experience any symptoms of skin irritation or an allergic reaction when using hair dyes containing this ingredient, it is important to seek medical attention right away.

Source

2-Amino-5-nitrophenol is a synthetic ingredient that is derived from the chemical reaction between 2-nitrophenol and ammonia. It is commonly used as a hair dye intermediate and is also found in some pharmaceutical products. The processing pathway for 2-Amino-5-nitrophenol involves the synthesis of 2-nitrophenol from nitrobenzene, followed by the reduction of 2-nitrophenol to 2-amino-5-nitrophenol using ammonia as a reducing agent. The resulting product is then purified and used in various applications.

Safety

The safety rating score of 2-Amino-5-nitrophenol varies depending on the rating system used. According to the Environmental Working Group's Skin Deep database, this ingredient has a moderate hazard rating of 5 out of 10, indicating that it may have some potential health concerns. Other sources, such as the European Chemicals Agency, classify 2-Amino-5-nitrophenol as a hazardous substance with potential risks to human health and the environment. It is important to note that the safety of this ingredient may also depend on the concentration and frequency of use in a product. As with any ingredient, it is recommended to research and consult with a healthcare professional before use.

Sustainability

2-Amino-5-nitrophenol is a chemical compound that is commonly used in the production of hair dyes. Unfortunately, the environmental impact of this ingredient is significant. The production of 2-Amino-5-nitrophenol involves the use of various chemicals and solvents, which can lead to the release of harmful pollutants into the air and water. Additionally, the disposal of unused or expired hair dyes that contain this ingredient can also contribute to environmental pollution. In terms of ethical sourcing practices, it is important to note that 2-Amino-5-nitrophenol is a synthetic compound that is typically produced in a laboratory setting. As such, there are no specific ethical concerns related to the sourcing of this ingredient. However, it is important for manufacturers to ensure that their production processes are safe and environmentally responsible, and that they dispose of any waste materials in a responsible manner. Additionally, consumers can make a positive impact by choosing hair dyes that are free from harmful chemicals and that are produced by companies with a commitment to sustainability and ethical practices.

Conclusion

In conclusion, 2-Amino-5-nitrophenol is a chemical compound that is commonly used in hair dyes and other cosmetic products. While it is effective in providing color, it has been linked to potential health risks such as skin irritation and allergic reactions. It is important to note that the safety of this ingredient is still being studied, and more research is needed to fully understand its effects on human health. In terms of sustainability, the sources of this ingredient are not renewable, and its production can have negative environmental impacts. Overall, it is important to weigh the potential benefits and negatives of using 2-Amino-5-nitrophenol in cosmetic products and to consider safer and more sustainable alternatives.
