This aldehyde compound has a molecular formula of C9H14O and is characterized by its linear structure with two double bonds in trans configuration.
At low concentrations, TRANS, TRANS-NONA-2,4-DIENAL can enhance the overall sensory experience of skincare and haircare products. It is often used in formulations aiming to create fresh, natural, or cucumber-inspired scents. However, formulators must exercise caution due to its potential skin sensitizing properties at higher concentrations.
The ingredient's volatility contributes to its top-note characteristics in fragrance compositions. It synergizes well with other green and fresh notes, making it valuable in creating complex, layered scents. When incorporated into leave-on skincare or haircare products, it should be used at concentrations below 0.01% to minimize the risk of skin irritation or allergic reactions. Proper dilution and stability testing are crucial to ensure product safety and efficacy.
