The Sourcing Desk
Technical notes for the people who actually write the specification — formulators, procurement teams and quality managers choosing between grades, forms and origins.
Grouped by what you are deciding, not by publication date.
01
Mint & menthol
Our largest vertical, and the one with the most decisions hidden inside a single product name.
- Menthol Crystals, Rice, Flakes or Molten: Choosing the Right FormThe same molecule in four physical forms. Which one suits your handling, dosing and melt process.
- Peppermint Oil or Mentha Arvensis Oil: What Buyers Should KnowTwo oils routinely confused in enquiries, and the compositional differences that decide which one your formulation needs.
- Spearmint or Peppermint: Carvone and Menthol Character in FormulationHow the dominant constituent changes the sensory result, and where each belongs.
02
Clove, eucalyptus & citrus
Where the assay figure on the certificate often is the product grade.
- Eugenol Grades Explained: Rectified 99%, USP and the Derivative ChainWhat separates rectified from pharmacopoeial eugenol, and what the derivatives are used for.
- Cineol Content in Eucalyptus Oil: 60%, 70% IP/BP and Eucalyptol 99.5%A worked example of a grade defined by a single number on the specification.
- D-Limonene: One Molecule, Two Very Different MarketsThe same isolate sold into flavour and into industrial solvent applications, at different specifications.
03
Specification & identification
Getting the paperwork right before the material ships.
04
Formulation & chemistry
Building blocks and functional ingredients.
- Non-Menthol Cooling Agents: WS-3, WS-5 and WS-23 ComparedCooling without menthol character — onset, duration and where each is typically used.
- Aroma Chemicals: Building Blocks of Modern FragrancesHow synthetic and natural-derived aroma chemicals function in a fragrance brief.
