What is the solubility profile of this cinnamon bark oil?
Cinnamon bark oil is a non-polar essential oil: it dissolves readily in ethanol and fixed oils, blends with most fragrance materials, and is essentially insoluble in water and glycerin. This behavior is standard for steam-distilled spice oils and is important for formulation and cleaning up.
Solubility Profile
| Solvent / system | Solubility | Note |
|---|---|---|
| 70% ethanol | 1 vol in 3 vol, clear solution | Standard miscibility test per GB/T 11425-2008 |
| 95% / anhydrous ethanol | Freely soluble | Used for perfumery dilutions and tinctures |
| Fixed oils (jojoba, almond, MCT) | Freely soluble | For carrier blends and massage oils |
| Vegetable waxes / candle wax | Soluble in fragrance phase | For scented candles; melt-phase addition |
| Water | Insoluble | Requires solubilizer (e.g. polysorbate) for aqueous use |
| Glycerin | Insoluble | Not suitable as carrier |
- In aqueous applications (room sprays, bath products), use a solubilizer such as Polysorbate 20/80 (typically 2-4 parts per part of oil) with gentle heating
- In candles, add the oil to melted wax at 60-65°C and stir thoroughly; cinnamaldehyde-rich oils can accelerate wax discoloration, so use a stabilizer and test your specific wax
- Because the oil is denser than water, water separation during distillation is straightforward with an insulated oil-water separator at 68-75°C
