TRANS-2-UNDECENAL

Description

TRANS-2-UNDECENAL is an organic compound with the molecular formula C11H20O, belonging to the class of aldehydes. This colorless to pale yellow liquid possesses a distinctive fresh, citrusy, and slightly waxy odor reminiscent of cilantro leaves. In skincare and haircare formulations, TRANS-2-UNDECENAL serves multiple functions, primarily as a fragrance ingredient and antimicrobial agent.

The compound exhibits potent antimicrobial properties, effectively inhibiting the growth of various bacteria and fungi. This makes it valuable in preserving cosmetic formulations and potentially addressing skin and scalp conditions associated with microbial imbalances. Its fresh, green scent contributes to the overall sensory experience of products, masking less pleasant base odors and enhancing user satisfaction.

TRANS-2-UNDECENAL is generally used in low concentrations due to its strong odor profile and potential skin sensitizing effects at higher levels. Formulators must carefully balance its inclusion to maximize benefits while minimizing risks. The ingredient finds applications in a wide range of personal care products, including shampoos, conditioners, body washes, and facial cleansers, where it imparts both functional and olfactory benefits.
