2-DODECENAL.

Optional CAS 4826-62-4 / PERFUMING

A synthetic aldehyde compound that serves primarily as a fragrance ingredient, delivering a distinctive citrus-mandarin scent profile to skincare formulations. This reactive alpha,beta-unsaturated aldehyde possesses mild antibacterial properties but functions predominantly as a sensory enhancer rather than an active treatment ingredient. While safe at regulated concentrations, it requires careful formulation due to its potential for skin sensitization.

Summary

perfuming antimicrobial

Science

Mechanism of Action

Functions by binding to olfactory receptors to impart a fatty, waxy, mandarin-like aroma to products. As a reactive aldehyde compound, it can provide mild antimicrobial activity through its interaction with bacterial cell components, though this secondary benefit is minimal compared to its primary fragrance function.
