Notes

Origanum majorana is a small herb of the mint family, native to the eastern Mediterranean and western Asia. It is grown as a culinary herb and as an oil crop. Egypt is a major growing source for the fragrance trade.

Sweet marjoram oil has its own page. Its typical constituents are terpinen-4-ol and cis-sabinene hydrate, with γ-terpinene, α-terpineol and linalyl acetate. cis-Sabinene hydrate gives the warm herbal note characteristic of the species.

The absolute is made from dried flowering tops by solvent extraction to a concrete, then washed with ethanol, chilled, filtered of waxes and freed of alcohol. It keeps fewer light monoterpenes and more heavy matter, so it smells rounder and lasts longer.

The names are easily confused. On the market, Spanish marjoram is usually Thymus mastichina, a thyme rich in 1,8-cineole. Products sold as marjoram absolute Spain should be checked for source species.

In perfumery, sweet marjoram absolute gives a warm herbal note for fougères, aromatic and spicy accords. It links well with lavender, clary sage and woody notes.
