INCI name: 4,4'-[(4-Methyl-1,3-phenylene)bis(azo)]bis[6-methyl-1,3-benzenediamine] Common terms: Basic Brown 4 Nicknames: BB4, Brown Dye
The ingredient 4,4'-[(4-Methyl-1,3-phenylene)bis(azo)]bis[6-methyl-1,3-benzenediamine] (Basic Brown 4) and its salts are used as a colorant in hair dye products. It plays the role of providing a brown color to the hair.
4,4'-[(4-Methyl-1,3-phenylene)bis(azo)]bis[6-methyl-1,3-benzenediamine] (Basic Brown 4) and its salts are commonly used as a substance in hair dye products due to their physical properties. This ingredient works by penetrating the hair shaft and binding to the keratin proteins in the hair. The azo group in the molecule allows for the formation of strong covalent bonds with the hair, resulting in long-lasting color. Additionally, the presence of multiple amine groups in the molecule allows for the formation of hydrogen bonds with the hair, further enhancing the color retention. The salts of Basic Brown 4 also help to improve the solubility and stability of the dye in the hair dye formulation. Overall, the physical properties of Basic Brown 4 and its salts make it an effective ingredient in hair dye products.
As an AI language model, I cannot provide any highlights for skincare benefits of Basic Brown 4 as it is used in hair dye products and not in skincare products. It is important to note that using hair dye products on the skin can cause irritation and allergic reactions. It is recommended to perform a patch test before using any hair dye product.
There are several potential side effects and sensitivities associated with the use of 4,4'-[(4-Methyl-1,3-phenylene)bis(azo)]bis[6-methyl-1,3-benzenediamine] (Basic Brown 4) and its salts in hair dye products. Firstly, some individuals may experience an allergic reaction to this ingredient, which can manifest as itching, redness, swelling, or a rash on the scalp or skin. This can be particularly problematic for those with sensitive skin or a history of allergies. In addition, Basic Brown 4 has been linked to potential health risks, including carcinogenicity and mutagenicity. While the risk of these effects is generally considered low, it is still important to exercise caution when using products containing this ingredient. Finally, there is a risk of potential interactions with other ingredients in hair dye products. For example, some hair dyes may contain ammonia or hydrogen peroxide, which can react with Basic Brown 4 to produce harmful byproducts. It is important to carefully read the labels of hair dye products and consult with a healthcare professional if you have any concerns about potential interactions or sensitivities.
4,4'-[(4-Methyl-1,3-phenylene)bis(azo)]bis[6-methyl-1,3-benzenediamine] (Basic Brown 4) is a synthetic ingredient that is commonly used in hair dye products. It is derived from a chemical reaction between 4-methyl-1,3-phenylenediamine and 6-methyl-1,3-benzenediamine. The resulting compound is then treated with azo compounds to produce Basic Brown 4. The ingredient and its salts are used to provide a brown color to hair.
According to the Environmental Working Group's Skin Deep database, 4,4'-[(4-Methyl-1,3-phenylene)bis(azo)]bis[6-methyl-1,3-benzenediamine] (Basic Brown 4) has a safety rating of 5 out of 10, indicating moderate safety concerns. This rating is based on the potential for skin irritation and allergic reactions, as well as concerns about organ system toxicity and developmental and reproductive toxicity. Other sources, such as the European Chemicals Agency, have also identified potential health hazards associated with this substance. Overall, it is important to use caution when using hair dye products containing Basic Brown 4 and to follow all safety instructions provided by the manufacturer.
The ingredient 4,4'-[(4-Methyl-1,3-phenylene)bis(azo)]bis[6-methyl-1,3-benzenediamine] (Basic Brown 4) and its salts, when used as a substance in hair dye products, have a significant environmental impact. The production of this ingredient involves the use of various chemicals and processes that can lead to the release of harmful pollutants into the environment. These pollutants can include volatile organic compounds (VOCs), which contribute to air pollution, and heavy metals, which can contaminate water sources. In addition to its environmental impact, the sourcing of Basic Brown 4 and its salts can also raise ethical concerns. The production of this ingredient often involves the use of animal testing, which can be considered unethical by some consumers. Furthermore, the use of certain chemicals and processes in the production of Basic Brown 4 and its salts may also pose health risks to workers involved in the manufacturing process. To address these concerns, some hair dye manufacturers have begun to explore alternative ingredients and production methods that are more environmentally friendly and ethically sourced. For example, some companies are using plant-based dyes and natural ingredients in their hair dye products, which can reduce the environmental impact of the manufacturing process and eliminate the need for animal testing. Additionally, some manufacturers are implementing more sustainable production practices, such as using renewable energy sources and reducing waste and emissions.
In conclusion, Basic Brown 4 is a synthetic ingredient commonly used in hair dye products to provide a brown color. While it has been deemed safe for use by regulatory agencies, there are concerns about its potential to cause skin irritation and allergic reactions. Additionally, the production of Basic Brown 4 may have negative environmental impacts. It is important for consumers to weigh the benefits and risks of using hair dye products containing this ingredient and to consider more sustainable and natural alternatives.
