Practical formulation guide
Usage level: 0.5% - 3%
How to use and incorporate: Add at the end of the process, with the base below 40 °C/104 °F, so volatile notes are not lost. In water-based products (toners, gels, shampoo, body mist) first premix with a solubilizer —polysorbate 20, Oleth-20 or PEG-40 hydrogenated castor oil— at a 1:3 to 1:5 ratio and then add to the water.
Formulation tips:
- Citrus oil: may be photosensitizing if obtained by expression; in leave-on products for sun-exposed areas, limit its concentration. Oxidizes quickly: keep tightly closed and refrigerated.
- Declare on the label the fragrance allergens naturally present in the essential oil when required by the regulations of the destination market.
- For aromatic blends, combine top notes (citrus), middle notes (floral, herbal) and base notes (woods, resins) and let the blend mature for 24–48 hours.
- Before scaling up, make a pilot batch and run a stability test (cycles at 4 / 25 / 45 °C/39 / 77 / 113 °F for 4 weeks, checking odor, color, pH, viscosity and separation) in the final packaging.
Compatibility: Soluble in vegetable oils, esters and alcohol; insoluble in water. May change the viscosity of gels and shampoos and attack some plastics (polystyrene): prefer amber glass, PET or lined aluminum.
Storage: Store in an amber bottle in a cool place. Shelf life: 1–2 years.
Precautions: Do not apply undiluted to the skin. Keep out of reach of children. Avoid contact with eyes and mucous membranes. Flammable: keep away from flames and heat sources. See the Safety Data Sheet.
