Eugenol is a naturally occurring constituent of a number of natural essential oils. It has a variety of useful applications but (like all essential oils), Eugenol is also an extremely potent ingredient and should be used with caution if skin sensitivities are a concern.
Eugenol has found extensive use in perfumery and fragrance composition. As such, it appears in a very broad range of skincare, cosmetic and household products from moisturisers, lotions and creams, to shampoos, conditioners and body washes. It is also a primary active ingredient in sensitive teeth toothpastes.
Eugenol is extracted from clove buds, cinnamon leaves, and holy basil by the process of steam distillation.
EU regulations specify that certain fragrance oils commonly found in natural essential oils must be labelled separately on ingredient lists on cosmetic product labels. The EU governing bodies specify this because they are recognised as potential allergens which can irritate sensitive skin. Eugenol is one of these recognised allergens and may not be suitable for those with very sensitive skin.
Eugenol comprises approximately 75%-85% of clove essential oil, 70%-80% of cinnamon leaf oil, and 30%-50% of holy basil leaf oil.
