3,4-DIHYDRO-5-METHYLNAPHTHALENONE

Description

3,4-Dihydro-5-methylnaphthalenone is a synthetic aromatic compound used in select haircare formulations. This molecule belongs to the naphthalene family and is characterized by its cyclic structure and methyl substituent. It functions primarily as a fragrance ingredient, imparting a woody, amber-like scent to hair products.

In haircare applications, 3,4-dihydro-5-methylnaphthalenone is utilized in small concentrations, typically below 1%, to enhance the olfactory profile of shampoos, conditioners, and styling products. Its molecular structure allows for slow evaporation, contributing to the longevity of the fragrance on hair. This ingredient also demonstrates some fixative properties, helping to stabilize other volatile scent components in the formulation.

While primarily employed for its aromatic qualities, 3,4-dihydro-5-methylnaphthalenone may offer secondary benefits in haircare. Some studies suggest it possesses mild antimicrobial properties, potentially contributing to scalp health. However, its use is strictly regulated due to potential skin sensitization concerns. Formulators must adhere to established safety guidelines and concentration limits to ensure product safety and compliance with cosmetic regulations.
