The fatty acid composition of Calendula oil is somewhat comparable to that of wood oil (Tung oil). The manner of production of calendula oil is, completely harmless and safe, both for people and the environment.

The composition of Calendula oil and with it its reactivity hinges on its very special fatty acid composition, viz. the C18:2 and conjugated C18:3 fatty acids.
