Lactonic

Milk, cream and butter: the gamma- and delta-lactones

lactonic 157 notes 195 materials 6 anchors

What it smells like

The dairy-fat register, and a texture as much as a smell. Split out of creamy_woody in v2, because creamy_woody is santalol: a WOOD that has milkiness. 26 of 70 notes carrying it were using it as a milk substitute, butter and milk among them.

Where it stops

Lactonic is the milkiness with no wood. Creamy Wood is the wood that has it. Tropical keeps the fruit percept of the same lactones. That is why coconut carries both and milk carries only one.

Smells most like

butter - and in the same register, milk, ricotta.

Notes that load on it

Notes from our catalogue whose position on this facet is 0.40 or higher, strongest first. A note is not filed under one facet: it carries a value on all 34 at once, and these are the ones where this axis is doing real work.

Materials that carry it

Real substances, each keyed by its CAS registry number, that an external perfumery vocabulary publishes with a term meaning this facet outright. This is the layer that makes a facet checkable against something outside our own database.

Showing 30 of 195. The full set ships with the published standard rather than being paginated here.

Reading the two flags

Declarable means the substance appears in Annex III of the EU Cosmetics Regulation, so it has to be named on the ingredient list once it passes a concentration threshold. IFRA means an IFRA Standard restricts or prohibits its use. Both are facts about the substance, not about any fragrance: a perfume can contain a declarable material below the threshold and never print it, and a restricted material used within its limit is used correctly.

The source also supplies no common name for a large share of materials, so those display as a bare registry number and are ranked last. They are kept because they are real evidence: dropping them would make the vocabulary look better described than it is.

Anchor terms

A facet on its own is just a word we chose. An anchor is what makes it checkable: a term in an external, independently maintained vocabulary of odour descriptions, built for perfumery materials rather than for us. The material list above is drawn from the direct terms only, because a partial term corroborates too weakly to stand as evidence on its own.

Direct Terms that mean this facet outright
  • butter
  • buttery
  • buttery, fresh butter
  • dairy
  • lactonic
  • milky
Partial Terms that lean this way but also load elsewhere
  • coconut
  • creamy
  • sour milk
