2-NONYLCROTONALDEHYDE

Description

2-Nonylcrotonaldehyde is a synthetic fragrance ingredient commonly used in both skincare and haircare formulations. This compound belongs to the aldehyde family and is characterized by its floral, fruity scent with subtle green undertones. Its molecular structure consists of a long hydrocarbon chain attached to an unsaturated aldehyde group, contributing to its distinctive olfactory profile.

In skincare and haircare products, 2-Nonylcrotonaldehyde serves primarily as a fragrance enhancer, imparting a pleasant aroma to various formulations. It is often incorporated into perfumes, lotions, shampoos, and conditioners. The ingredient's low molecular weight allows for efficient diffusion, providing a long-lasting scent experience.

While 2-Nonylcrotonaldehyde is generally considered safe for cosmetic use, it may cause skin sensitization in some individuals. As with many fragrance compounds, patch testing is recommended for those with sensitive skin or a history of allergic reactions. Formulators typically use this ingredient in low concentrations to minimize potential adverse effects while still achieving the desired fragrance profile in their products.
