OCTAHYDRO-5,5-DIMETHYLNAPHTHALENE-2-CARBALDEHYDE

Description

Octahydro-5,5-dimethylnaphthalene-2-carbaldehyde, also known by its trade name Lyral, is a synthetic fragrance ingredient commonly used in haircare products. This colorless to pale yellow liquid possesses a fresh, floral scent reminiscent of lily of the valley. Its molecular structure consists of a saturated naphthalene ring with two methyl groups and an aldehyde functional group.

In haircare formulations, Lyral serves as a fragrance enhancer, imparting a pleasant aroma to shampoos, conditioners, and styling products. Its ability to blend well with other scents makes it a versatile choice for creating complex fragrance profiles. The compound has a relatively low molecular weight, allowing for effective diffusion and long-lasting scent retention on hair.

While Lyral has been widely used in the past, recent studies have raised concerns about its potential to cause allergic reactions in some individuals. As a result, regulatory bodies in certain regions have imposed restrictions on its use in cosmetic products. Formulators are now exploring alternative fragrance ingredients to replace Lyral in haircare formulations, focusing on options that maintain desirable scent profiles while minimizing the risk of skin sensitization.
