What is 2-Trans, 6-Trans-Nonadienyl Acetate?

2-Trans, 6-Trans-Nonadienyl Acetate, also known by its chemical name (2E,6E)-Nona-2,6-dienyl Ethanoate, is a compound primarily used in the cosmetic industry for its perfuming properties. This ingredient is a type of ester, which is a chemical compound derived from an acid (in this case, acetic acid) in which at least one -OH (hydroxyl) group is replaced by an -O- (alkoxy) group.

The source of 2-Trans, 6-Trans-Nonadienyl Acetate can be both natural and synthetic. Naturally, it can be found in certain essential oils and plant extracts, contributing to their characteristic scents. However, for commercial use in cosmetics, it is often synthesized in laboratories to ensure consistency and purity.
