TRIMETHYLUNDECADIENAL

Description

Trimethylundecadienal is a potent synthetic fragrance ingredient commonly used in haircare formulations. This aldehyde compound is characterized by its fresh, citrusy, and slightly floral aroma profile, reminiscent of lemon and lime with subtle green undertones. Its molecular structure allows for long-lasting scent retention, making it valuable in shampoos, conditioners, and styling products.

In haircare applications, trimethylundecadienal serves primarily as an olfactory enhancer, contributing to the overall sensory experience of the product. Its low molecular weight enables it to disperse effectively throughout formulations, ensuring consistent fragrance distribution. Typically used in concentrations below 1%, this ingredient helps mask unpleasant base odors and provides a clean, invigorating scent.

While primarily valued for its fragrance properties, trimethylundecadienal may also offer mild antimicrobial benefits, potentially contributing to product preservation. However, it's important to note that some individuals may experience skin sensitivity to this ingredient. Formulators should consider patch testing and adhere to recommended usage levels to minimize the risk of irritation. As with many fragrance compounds, trimethylundecadienal should be used judiciously in products intended for sensitive scalps or those prone to allergic reactions.
