2-ETHYLIDENEDECANAL

Description

2-Ethylidenedecanal is a versatile synthetic fragrance ingredient commonly used in both skincare and haircare formulations. This aldehyde compound contributes a fresh, citrusy, and slightly floral scent to products, enhancing their olfactory appeal. Its chemical structure consists of a ten-carbon chain with an ethylidene group attached, resulting in a molecular weight of 168.28 g/mol.

In skincare applications, 2-ethylidenedecanal serves as a masking agent, helping to neutralize unpleasant odors associated with certain active ingredients. It also imparts a subtle, pleasant aroma to creams, lotions, and serums. In haircare products, this ingredient adds a refreshing scent to shampoos, conditioners, and styling products.

While primarily used for its fragrance properties, 2-ethylidenedecanal may also exhibit mild antimicrobial effects, potentially contributing to product preservation. However, its concentration in formulations is typically low to minimize the risk of skin sensitization. As with any fragrance ingredient, patch testing is recommended for individuals with sensitive skin or a history of allergic reactions. Formulators should adhere to regulatory guidelines regarding its usage limits in cosmetic products.
