In short

Tamanu oil is the fixed oil pressed from the nuts of Calophyllum inophyllum. It is a heavy green carrier oil with a nutty, walnut-like and faintly resinous smell.

What Tamanu Oil smells like

A perfume glossary (Première Peau) describes tamanu as a heavy green oil smelling of crushed walnuts left on warm earth — nutty, bitter, faintly resinous, with a curry-leaf undertone — whose bitterness recedes on drying towards a warm, resinous, praline-like sweetness; the same glossary notes that it has minimal aromatic use in perfumery. AromaWeb describes a strong, nutty aroma.

What makes Tamanu Oil distinctive

A carrier with a smell of its own: nutty, bitter and resinous, drying towards a praline-like sweetness, though a glossary notes its minimal aromatic use.

Where the descriptions disagree: The glossary lists tamanu among base notes but also says it has minimal aromatic use in perfumery; other references describe it as woody rather than nutty.

How Tamanu Oil is used

Used mainly in cosmetics; in perfumery it serves as a carrier with a nutty, earthy character of its own.

Typical role: solvent (dilutes or carries other materials); fixative (slow to evaporate; helps a blend last and holds lighter notes).

How Tamanu Oil differs from similar materials

Caprylic/Capric Triglyceride
Caprylic/capric triglyceride is a light, nearly odourless carrier; tamanu oil is a heavy green oil with a nutty, bitter, resinous smell of its own.

Each difference compares the published descriptions of the two materials. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.

Formulation considerations

A fixed (vegetable) oil, not an essential oil: it is pressed from the seeds and does not evaporate. The resin of the same tree is a different material. PubChem's substance records give CAS 241148-25-4 for Calophyllum inophyllum seed oil (tamanu oil).
