3-Hexenol
What is 3-Hexenol?
3-Hexenol, chemically known as (Z)-hex-3-en-1-ol, is an unsaturated primary alcohol featuring a six-carbon chain with a cis double bond between the third and fourth carbons. Naturally present in green leaves, herbs, and grasses, it captures the crisp, leafy aroma of fresh-cut vegetation. In cosmetics, it is either extracted from plant sources or synthesized for precision and purity. Primarily employed in the fragrance category of personal care products such as lotions, shampoos, and body washes, it imparts a vibrant green note that enhances sensory appeal. Beyond scent, its hygroscopic properties allow it to bind water molecules, supporting moisture retention in formulas. As a solvent, it facilitates the blending of oils and actives, while its viscosity-controlling action helps achieve smooth, stable textures for better application and feel.
