Vanilla

Vanilla in fragrance is rarely the natural extract (which is expensive and uneven) — it's usually vanillin or ethyl vanillin, both synthetics that read as vanilla without the variability. Vanilla appears as a base note in everything from baby-soft florals (it grounds them) to dense gourmands (it carries them). The community shorthand: a "vanilla bomb" is a fragrance where vanilla is the obvious headline (e.g., Lattafa Khamrah, Kayali Vanilla 28); a "vanilla touch" means it's used as a polishing agent in the base. Both work — the question is whether you want the headline note or the supporting role.
