Eugenol 丁香酚
Introduction: Eugenol is an allyl chain-substituted guaiacol, i.e. 2-methoxy-4-(2-propenyl)phenol. Eugenol is a member of the allylbenzene class of chemical compounds. It is a clear to pale yellow oily liquid extracted from certain essential oils especially from clove oil, nutmeg, cinnamon, and bay leaf. It is slightly soluble in water and soluble in organic solvents. It has a pleasant, spicy, clove-like odor. Eugenol is used in perfumeries, flavorings, essential oils and in medicine as a local antiseptic and anaesthetic. It was used in the production of isoeugenol for the manufacture of vanillin, though most vanillin is now produced from petrochemicals or from by-products of paper manufacture.

ENVIRONMENTAL FATE
No data on the mobility of eugenol were presented in the dossier. Different eugenol QSAR Koc estimations were considered during the peer review. These estimations revealed the high uncertainty associated with them, and were not considered appropriate for the environmental assessment. Therefore, it was agreed that a batch soil adsorption/desorption study in four soils must be performed with eugenol. In the absence of experimental data, it was agreed to use worst case estimates for environmental modelling (Koc = 10 mL/g (1/n = 0.9) for PEC SW and PEC GW and Koc = 10000 mL/g (1/n = 0.9) for PEC sed ) to represent an appropriate worst case for each of the compartments.
Usage: Eugenol is a natural plant extract which exhibits insecticidal, fungicidal and anti-bacterial activity. At high concentrations it can also be used as a herbicide.
Application: Mode of action: Prohibits the growth of both Gram-positive and Gram-negative bacteria and fungi. Strong insect repellent. Function mechanism: It has good effect on controlling pests. After spraying, it kills the brachsporozoites and pathogen, meanwhile it changes the procedure of disease producing germ invasion, finally it will weaken and eliminate the disease. Product Feature: 1. High-efficiency, Broad-spectrum, Rapid-killing and Safe to the environment. 2. It has special effect on preventing and curing diseases caused by fungi. Best result being achieved if using it at the initial stage of diseases. After 24 hours of spraying, the disease-spot will lose water, then it will turn withered, finally it will be well cured.
