Honeysuckle Absolute Glossary: Terms a Maker Needs

These are the terms a maker meets when buying and using a honeysuckle absolute, in the order you meet them: what the material is, how it smells, what the paperwork says, and how to use it without trouble. Where an ISO standard, a regulator or a study defines or measures a term, we cite it. Where a term is plain trade usage, we say so, and we do not dress it up as a standard.

One honest limit first. ISO 9235 is the vocabulary standard for aromatic natural raw materials. Its catalogue page shows edition 3, June 2021, confirmed in a 2026 review, with the scope "terms and definitions relating to aromatic natural raw materials". We could not read its definitions (the text is paid and ISO's online browsing platform refused our fetch), so the process terms below are described from our own how-it-is-made page and general usage, not quoted from the standard.

What the material is

Absolute. The liquid left when a concrete is washed in ethanol, chilled and filtered. Ours is described on our how-it-is-made page as a solvent process, hexane in practice, then the ethanol wash and chill. It is not an essential oil. See from concrete to absolute.

Concrete. The waxy, solid-to-semi-solid first extract, made with a hydrocarbon solvent, from which an absolute is later made.

Resinoid. An extract of a resin or gum rather than a flower. Trade usage. Not relevant to honeysuckle, but it appears on supplier lists next to absolutes.

Essential oil. A volatile oil obtained by distillation or pressing. Trade usage. There is no steam-distilled honeysuckle essential oil; "honeysuckle oil" on a label means an absolute, a fragrance oil or a blend, and the difference is the subject of absolute versus fragrance oil.

Fragrance oil. A composed scent made from aroma chemicals, natural materials or both. It carries its own usage limits and paperwork from its maker. We do not sell one.

Neat. Undiluted. Our absolute is sold neat, with no carrier or additive, so the dilution maths is yours.

Infusion, maceration. Steeping plant material in a carrier oil or alcohol. It is a different product from an absolute, with a spoilage risk when fresh flowers sit in oil, as Penn State Extension (2024) explains for herbs.

Tincture. Plant material steeped in ethanol. Not an absolute: it skips the concrete and the chill.

How it smells and where it sits

Heart note (middle note). A material that sits between the opening and the base of a perfume. Our product page places honeysuckle absolute in the middle. Note positions are trade convention, not measured quantities.

Drydown. What a scent smells like after the first minutes on skin or paper. Trade usage. We hold no drydown timelines for our absolute and do not state any.

Sillage. How far a scent carries around the wearer. Trade usage, and subjective.

Accord. A blend of materials that reads as one new impression, for example a floral built from several parts.

Soliflore. A fragrance built around a single flower. The idea is the basis of the rollerball perfume oil recipe, if you want to see one worked.

Fixative. A material added to slow the evaporation of lighter ones. Trade usage, and the effect depends on the blend.

Organoleptic. Judged by the senses (smell, sight, touch), not by an instrument. The "complies" entries for appearance and smell on our certificate are organoleptic checks: the laboratory's judgement that the smell matches "unique aroma of honey suckle".

Green-floral. Our product page describes the aroma as "nectarous, lush, and green-floral, with a soft jasmine-adjacent warmth". A description, not a measurement.

What the paperwork says

COA (certificate of analysis). A laboratory's report on one batch. Ours covers batch HONLUUUNUNC007A: appearance, smell, relative density, refractive index and optical rotation, and nothing else. Read it line by line in how to read a COA.

Relative density. The density of the oil compared with that of water at a stated temperature. ISO 279:1998 is the method standard (catalogue entry). The batch on our certificate reads 0.989 at 20 C, so 1 ml weighs about 0.989 g.

Refractive index. How strongly the liquid bends light, method in ISO 280:1998 (catalogue entry). Our batch reads 1.509 at 20 C.

Optical rotation. How far the liquid turns polarised light, method in ISO 592:1998 (catalogue entry), which notes that viscous or highly coloured oils are measured in solution. Our batch reads +1.88 degrees, inside a window of -5 to +5.

GC-MS. Gas chromatography with mass spectrometry, which separates and identifies the volatile compounds in a sample. A 2025 Molecules study used it on dried Lonicera japonica flower buds and found 80 volatile compounds. Our published certificate has no GC-MS table.

Headspace. The vapour above a sample, which is what headspace methods analyse (the same study used headspace SPME). It is how scent is captured without extracting it.

Residual solvent. Solvent left in a finished extract. Our published certificate gives no figure, so ask in writing before ordering. See solvent residue in absolutes.

Best-by. A date a supplier prints. Ours reads 02/05/2027 with no stated date format. It is not a shelf life, and we state none.

Using it without trouble

Dilution. The share of absolute in the total. Our guidance for skin is 0.5% to 2% in a carrier: 1% is 1 g of absolute with 99 g of carrier, which at 0.989 g per ml is a little over 1 ml, about 20 drops (at 20 drops per ml, which varies by dropper, so weigh).

Patch test. Applying a small diluted amount to a small skin area before wider use, which our safety copy asks for. Details in skin basics.

Sensitisation. The skin learning to react to a substance, so later exposures cause reactions at doses that were tolerated before. A 2002 Contact Dermatitis study reported that air-oxidised linalool sensitised guinea pigs while unoxidised linalool did not.

Oxidation (autoxidation). Reaction with oxygen over time, the reason for keeping caps tight and decanting working amounts into smaller airtight bottles.

Flash point. The lowest temperature at which a liquid gives off enough vapour to ignite. The NIOSH Pocket Guide gives -7 F for hexane. We publish no flash point for our absolute.

Solubility. How well one material dissolves in another, such as an absolute in your base. We have no solubility data for ours in any base, so test a small amount.

IFRA. The fragrance industry's standards body. Its Standards are of three kinds, Prohibition, Restriction and Specification, and Restriction Standards list maximum concentrations by product category. The compiled IFRA Standards up to the 51st Amendment (January 2024) include Restriction Standards for two jasmine absolutes but no entry naming Lonicera or honeysuckle that we could find, and we publish no IFRA certificate. A 52nd Amendment was in consultation as of August 2026. Ask a regulatory consultant about your product; see IFRA limits and honeysuckle absolute.

If a term you met is missing, a supplier or regulatory consultant can define it for your product type. We sell one material, the honeysuckle absolute, in sizes from 0.5 oz to 400 lb.
