2-METHYLNAPHTHALENE

Description

2-Methylnaphthalene is a polycyclic aromatic hydrocarbon compound derived from coal tar or petroleum. This organic molecule consists of two fused benzene rings with a methyl group attached, giving it unique properties for use in cosmetic and personal care formulations. In haircare products, 2-Methylnaphthalene functions primarily as a fragrance ingredient and solvent.

The compound exhibits a low molecular weight and possesses a characteristic naphthalene-like odor. Its solvent properties make it useful for dissolving and dispersing other ingredients in hair care formulations. 2-Methylnaphthalene can enhance the penetration of active ingredients into the hair shaft, potentially improving the efficacy of treatments and styling products.

However, it's important to note that 2-Methylnaphthalene has been associated with potential skin sensitization and irritation in some individuals. As a result, its use in cosmetic products is regulated, and concentration limits are typically imposed by regulatory bodies. Formulators must carefully consider the appropriate dosage and potential allergenicity when incorporating this ingredient into haircare products. Additionally, due to environmental concerns, alternatives to coal tar-derived ingredients are increasingly being sought in the cosmetics industry.
