Essential oils & personal care
Clove bud oil
Clove bud oil is distilled from the flower buds themselves, which are also the spice. It is finer and considerably more expensive than clove leaf oil, and because leaf oil is cheap and chemically similar, adulteration is the central commercial risk.
How it leaves the country.
- Bud oil
- From the buds. Rounder and sweeter, and the grade fragrance and flavour buyers want.
- Leaf oil
- From the leaves. Harsher, much cheaper, and the feedstock for eugenol isolation.
- Stem oil
- From the stems. Between the two in price and character.
- Eugenol
- Isolated from clove oil, mostly from leaf oil, and sold as a chemical rather than as an essential oil.
How it is graded.
A chemical purchase, verified by chromatography against a sealed retained sample. Nothing else settles this category.
- Eugenol content
- The primary constituent, and the headline number. It alone does not distinguish bud oil from leaf oil, which is exactly the problem.
- Minor constituents
- The compounds present in bud oil at different levels from leaf oil. This is what a full chromatogram shows and a single-number certificate hides.
- Adulteration
- Leaf oil sold as bud oil, and synthetic eugenol added. Both are invisible by smell and both are found by chromatography.
- Colour
- Pale yellow darkening with age and exposure. Very dark oil has usually been stored badly or is old.
- Specific gravity and refractive index
- Quick physical checks that catch gross adulteration cheaply.
- Skin sensitisation
- Eugenol is a recognised sensitiser with restrictions in cosmetic use in several markets.
How it is packed.
- Lined steel or aluminium drums
- The oil attacks some plastics and picks up contamination from reused drums.
- Full drums, minimal headspace
- Oxidation darkens the oil and shifts the composition.
- Dangerous goods
- Establish the classification for the specific material before booking.
- Heat and light
- Both degrade it. Stow away from the container walls and the door.
Where it grows.
North Maluku
Maluku
The historic clove islands, with buds going to both the spice trade and to distillation.
North Sulawesi
Sulawesi
Substantial clove production with distillation capacity.
Central Java
Java
Distillation serving the domestic and export flavour and fragrance trade.
West Sumatra
Sumatra
Clove growing with smaller-scale processing.
Documentation, where applicable.
- Certificate of analysis
- Full chromatography on the shipped lot rather than an eugenol figure alone.
- Safety data sheet
- A skin sensitiser and frequently a flammable liquid.
- REACH
- Essential oils entering the EU are chemicals, and the registration obligation sits on the European side.1
- Dangerous goods declaration
- Where the flash point of the specific batch puts it in a transport class.
Questions buyers ask.
How do I know it is bud oil and not leaf oil?
Full chromatography against a sealed retained sample, looking at the minor constituents rather than the eugenol figure. Eugenol content alone does not distinguish them, which is why a single-number certificate is not enough.
Why is bud oil so much more expensive?
Because the buds are the spice, so distilling them competes directly with selling them. Leaves are a by-product and buds are the crop.
Can I use it in cosmetics?
Within the limits your market sets, because eugenol is a recognised sensitiser. That is a question for your safety assessor before the formulation.
