Clove Essential Oil

 

Clove Essential Oil (CAS 8000-34-8, INCI name -distilled essential oil standardized to >85% eugenol, distilled from Syzygium aromaticum buds. Baisifu supplies food-grade, BP/USP and Ph.Eur. equivalent batches from a Xi’an facility, with every drum shipped with a COA, allergen declaration and IFRA documentation.

Botanical identity and chemistry

Clove Essential Oil is the steam-distilled volatile oil obtained from the dried flower buds of Syzygium aromaticum (L.) Merrill and Perry, an evergreen of the Myrtaceae family. The oil is dominated by eugenol, a guaiacol-type phenylpropanoid whose warm, sweet, spicy character and antimicrobial profile have anchored dental, flavour and fragrance work for generations. The same tree yields clove stem oil and clove leaf oil, but bud oil carries the highest eugenol and the finest odour and is the grade Baisifu standardises.

Distillation and standardisation

Dried buds are comminuted and charged to a stainless-steel still for steam distillation at atmospheric pressure; the yield typically runs 15 to 18 percent on a dry-bud basis. The crude oil is settled, filtered and standardised in-house to a minimum of 85 percent eugenol by GC-MS against a pharmacopoeial eugenol reference standard. Baisifu does not top up with synthetic eugenol or blend in leaf or stem oil; each drum is single-botanical-source bud oil with a documented chain back to the harvest region.

Active profile by GC-MS

The GC-MS fingerprint is anchored on the eugenol peak, with a reproducible secondary cast of eugenyl acetate, beta-caryophyllene, alpha-humulene and trace methyl salicylate. Baisifu records the complete chromatogram on every COA and rejects any batch whose secondary profile falls outside the historical control window, so formulators receive a consistent active drum after drum rather than a botanical variable.

Physical and sensory behaviour

Clove Essential Oil is a clear, mobile, pale-yellow to amber liquid with a density near 1.04 g/cm3, a refractive index around 1.528 at 20 degrees Celsius and a boiling point in the 250 degree range. Its odour is a powerful, warm, sweet-spicy clove top-to-body note with a persistent dry-down; in perfumery it blends with floral, citrus, herbaceous and woody materials and is a classic fixative for spicy and oriental accords.

Typical applications

Clove Essential Oil enters the following formulation workflows:

• dental and oral-care products
• medicated toothpaste and mouthwash
• pharmaceutical analgesic rubs
• spice and savoury flavours
• confectionery and baked-goods flavours
• perfumery and oriental fragrances

Formulation and blending notes

The oil is soluble in ethanol and fixed oils and dispersible in propylene glycol at typical use levels. Eugenol is a sensitiser at high concentration, so the final leave-on level must respect the IFRA limit for the category; in rinse-off and flavour systems the margin is wider. Clove oil can darken on prolonged exposure to iron or light, so stainless-steel or lined containers and nitrogen blanketing are used throughout handling and storage.

COA and batch documentation

Each drum ships with a Certificate of Analysis carrying the GC-MS chromatogram, eugenol assay, specific gravity, refractive index, heavy metals (Pb, As, Cd, Hg) and pesticide residue screen. An allergen declaration, an IFRA conformity statement and a Statement of Origin complete the pack, giving QC and regulatory teams everything they need in a single shipment.

Regulatory and compliance

Eugenol is listed as FEMA GRAS 2431 and is permitted in flavour and fragrance applications under the IFRA Code of Practice, with a quantitative limit set for leave-on skin products because of sensitisation potential. The oil is recognised in BP, USP and Ph.Eur. monographs for clove oil when the eugenol floor is met. Under EU CLP the concentrated oil is classified as hazardous (aspiration toxicant category 1, skin sensitiser category 1, eye damage category 1), so Hazmat labelling and UN 1993 shipping names apply for bulk movement.

Packaging, storage and supply

Clove Essential Oil is filled into 180 kg HDPE drums or 50 kg sample drums, nitrogen-blanketed and sealed under COA. Store in a cool, dry place away from direct sunlight; the recommended storage temperature is 15 to 25 degrees Celsius with a shelf life of 24 months from manufacture in original sealed packaging. Baisifu ships ex-Xi’an, MOQ 50 kg for sample development and 1,000 kg and above for production orders; standard lead time 7 to 15 days depending on batch availability, with express air freight on request.

Questions buyers ask

Is this bud oil, leaf oil or stem oil?

This is clove bud oil only. Baisifu does not blend in leaf or stem oil; the botanical part, the eugenol floor and the full GC-MS fingerprint are stated on the COA so buyers can verify the grade before use.

What eugenol level can you guarantee?

The standardised grade is assayed by GC-MS to a minimum of 85 percent eugenol against a pharmacopoeial reference standard; the exact figure and the full secondary fingerprint are printed on the COA of every drum.

How do you handle sensitisation compliance?

The IFRA conformity statement shipped with each drum states the permitted use level by product category; for leave-on skin formats the eugenol cap is lower than for rinse-off or flavour use, and Baisifu flags the applicable limit on the documentation pack so formulators can design within the margin.
