In short
Trimofix O is an IFF woody-amber material with earthy vetiver, smoky tobacco and musky nuances. It is used as a fixative and to lift woody compositions.
What Trimofix O smells like
Fraterworks describes Trimofix, an IFF material, as radiant nuances of earthy vetiver, subtle smoky tobacco and a touch of musky softness, usable in traces as a fixative or in overdose, and likens it in profile to Z11 (Ambraketal) with a shorter lifespan and intensity. IFF, its maker, describes Trimofix O as a powerful, diffusive amber-woody note with vetiver and smoky tobacco nuances and a slight musky undertone, a heart-to-base material that adds body and depth to leather, vetiver and tobacco notes.

What makes Trimofix O distinctive
Earthy vetiver, smoky tobacco and musk, likened by Fraterworks to Z11 with a shorter life.
How Trimofix O is used
Used in traces as a fixative or at higher levels in woody compositions, with vetiver oils and other woody synthetics.
Typical role: fixative (slow to evaporate; helps a blend last and holds lighter notes); modifier (used in small amounts to change the character of a blend).
How Trimofix O differs from similar materials
- Z11
- Fraterworks likens Trimofix to Z11 in profile but with a shorter lifespan and intensity; Trimofix also carries the vetiver, smoky tobacco and musk that Z11's dry amber does not. (compared directly by a cited source)
An asterisk marks a difference that a cited source states directly. The others compare the published descriptions of each material. Smell varies with grade, supplier and dilution; compare them side by side on blotters before substituting one for another.
