Description
Methyl chavicol is the main component of tarragon essential oil, making up to 75% of its composition. It occurs naturally in anise and its oil, bringing aromas reminiscent of licorice, herbs, and green notes to fragrance compositions. Perfumers often produce a nature-identical version of the ingredient in laboratories, ensuring consistent quality and helping preserve natural resources. The laboratory-produced version can derive from various sources, including renewable materials. Besides tarragon and anise, methyl chavicol occurs naturally in many herbs and fruits such as basil, fennel, oregano, parsley, dill, bay leaf, apple, and allspice.

Regulatory information
Methyl chavicol is a fully evaluated and frequently used fragrance ingredient. The state of California requires its inclusion on ingredient lists due to a potential link to serious health impacts. According to the official RIFM safety assessment, methyl chavicol is classified as a weak skin sensitizer, meaning it has a very low probability of causing a skin reaction such as redness, rash, or itching. These reactions can be difficult to pinpoint and are equally likely to be caused by natural and synthetic ingredients. IFRA has established standards for the acceptable concentrations of methyl chavicol that may be used in various consumer products.
