TRANS-TRIMETHYLUNDECADIENOL

Description

Trans-trimethylundecadienol is a synthetic fragrance ingredient commonly used in skincare and cosmetic formulations. This colorless to pale yellow liquid compound belongs to the class of unsaturated alcohols and is known for its fresh, floral scent profile with subtle green and woody undertones. Its chemical structure consists of a linear carbon chain with 11 carbon atoms, featuring two double bonds in a trans configuration and three methyl groups.

In skincare products, trans-trimethylundecadienol primarily functions as a fragrance component, contributing to the overall sensory experience of the formulation. It is often used in small concentrations, typically less than 1%, to impart a pleasant aroma without overwhelming other active ingredients. This compound has a relatively low molecular weight, allowing for good dispersion within various product bases such as creams, lotions, and serums.

While primarily utilized for its olfactory properties, trans-trimethylundecadienol also exhibits mild antimicrobial activity, potentially contributing to product preservation. However, it is important to note that this ingredient may cause skin sensitization in some individuals, particularly those with fragrance allergies. As with all fragrance components, patch testing is recommended before widespread use in skincare formulations.
