INCI Name and Common References

INCI Name: 2-METHYLNAPHTHALENE Common Terms: 2-MN, 2-Methyl-1-naphthalene Nicknames: N/A

Function

2-Methylnaphthalene is a fragrance ingredient commonly used in cosmetic formulations. It provides a pleasant scent to the product and helps to mask any unpleasant odors from other ingredients. It is also used as a solvent and can help to improve the texture and consistency of the product. However, it should be used in small amounts as it can be irritating to the skin and eyes in high concentrations.

Science

2-Methylnaphthalene is a polycyclic aromatic hydrocarbon (PAH) with a molecular formula of C12H10. It is a colorless liquid with a strong odor and is insoluble in water but soluble in organic solvents. In terms of its physical properties, 2-methylnaphthalene has a high boiling point of 270°C and a low melting point of 34°C. It also has a high vapor pressure, which means it can easily evaporate into the air. In terms of its function as an ingredient, 2-methylnaphthalene is often used as a solvent and as a starting material for the synthesis of other chemicals. Its high boiling point and low melting point make it useful for high-temperature reactions, while its solubility in organic solvents allows it to dissolve other substances. Overall, the physical properties of 2-methylnaphthalene make it a versatile ingredient in various chemical processes.

Benefits

There are no known skincare benefits associated with 2-METHYLNAPHTHALENE. In fact, it is not a common ingredient in skincare products and is primarily used in industrial applications. It is important to always check the ingredients list of skincare products and avoid any that contain potentially harmful or irritating ingredients.

Negatives

2-Methylnaphthalene is a chemical compound that is commonly used in the production of dyes, resins, and other industrial products. While it is generally considered safe for use in these applications, there are some potential side effects, sensitivities, and interactions that should be taken into consideration. One of the main concerns with 2-methylnaphthalene is its potential to cause skin irritation and sensitization. This means that individuals who are exposed to this chemical on a regular basis may develop a rash, itching, or other skin reactions. In some cases, this can lead to more serious conditions such as dermatitis or eczema. Another potential side effect of 2-methylnaphthalene is its ability to cause respiratory irritation. This means that individuals who inhale this chemical may experience coughing, wheezing, or other respiratory symptoms. In some cases, this can lead to more serious conditions such as asthma or bronchitis. In addition to these side effects, there are also some potential interactions with other ingredients that should be taken into consideration. For example, 2-methylnaphthalene may react with other chemicals to produce toxic fumes or other hazardous substances. It is important to carefully consider the potential interactions of this chemical with other ingredients before using it in any application. Overall, while 2-methylnaphthalene is generally considered safe for use in industrial applications, it is important to be aware of its potential side effects, sensitivities, and interactions with other ingredients. By taking these factors into consideration, individuals can ensure that they are using this chemical safely and effectively.

Source

2-Methylnaphthalene is a naturally occurring organic compound that can be found in coal tar and crude oil. It is a polycyclic aromatic hydrocarbon (PAH) that is derived from the naphthalene molecule. The processing pathway of 2-methylnaphthalene involves the extraction of coal tar or crude oil, followed by distillation to separate the various components. The 2-methylnaphthalene is then isolated through further purification processes such as chromatography or crystallization. Alternatively, 2-methylnaphthalene can also be synthesized through chemical reactions involving naphthalene and other reagents. However, this synthetic pathway is less common than the natural extraction method. Overall, 2-methylnaphthalene can be considered a derived ingredient, as it is derived from natural sources but may also be synthesized through chemical reactions.

Safety

The safety rating score for 2-METHYLNAPHTHALENE varies depending on the rating system used. According to the Environmental Working Group's Skin Deep database, 2-METHYLNAPHTHALENE has a moderate hazard rating of 5 out of 10, indicating that it may have some potential health concerns. Other sources, such as the National Library of Medicine's Hazardous Substances Data Bank, also suggest that 2-METHYLNAPHTHALENE may have some health risks, including respiratory irritation and potential carcinogenic effects. Overall, it is important to use caution when handling or using products containing 2-METHYLNAPHTHALENE and to follow all safety guidelines and precautions.

Sustainability

2-Methylnaphthalene is a chemical compound that is commonly used in the production of dyes, resins, and other industrial products. While it is not considered to be highly toxic or hazardous to human health, it can have negative environmental impacts if not handled properly. One of the main concerns with 2-methylnaphthalene is its potential to contaminate soil and water if it is released into the environment. This can happen during the manufacturing process or if products containing the compound are not disposed of properly. Once in the environment, 2-methylnaphthalene can persist for a long time and can be harmful to plants and animals. In terms of ethical sourcing practices, it is important to ensure that the production of 2-methylnaphthalene does not involve the exploitation of workers or the violation of human rights. This can be challenging, as the compound is often produced in countries with less stringent labor laws and regulations. Companies that use 2-methylnaphthalene in their products should work with suppliers who have a demonstrated commitment to ethical sourcing practices and who can provide transparency about their supply chain. Additionally, efforts should be made to reduce the overall use of 2-methylnaphthalene and to find alternative, more sustainable ingredients where possible.

Conclusion

In conclusion, 2-methylnaphthalene is a chemical compound that is commonly used in the production of dyes, solvents, and fragrances. While it has some potential benefits, such as its ability to repel insects and its use in the treatment of certain medical conditions, it also has some negative effects, including its potential to cause skin irritation and respiratory problems. 2-methylnaphthalene can be found in various sources, including coal tar and crude oil, and its safety and sustainability depend on the specific application and production methods used. Overall, it is important to use caution when handling and using this ingredient, and to consider alternative, more sustainable options whenever possible.
