How soluble is this bergamot oil in different solvents?
Being a citrus oil rich in monoterpenes and esters, this bergamot oil dissolves readily in ethanol and fixed oils, and is essentially insoluble in water.
Solubility Profile
| Solvent | Solubility |
|---|---|
| Ethanol 85% | Soluble 1+1 (ISO 3520:2022) |
| Ethanol 90% | Soluble 1+2 (GB/T 14453-2008 / FCC 1996) |
| Fixed oils (jojoba, sweet almond, fractionated coconut) | Miscible in all proportions |
| Vegetable glycerin | Poorly soluble |
| Water | Insoluble — essential oils are hydrophobic |
| Propylene glycol / dipropylene glycol | Soluble in practical use ratios |
- The clear 1+1 / 1+2 ethanol test is a standard purity check that detects adulteration or oxidation
- For aqueous products (toners, beverages, air fresheners), dissolve the oil in ethanol or a solubilizer (e.g. polysorbate, cyclodextrin) before mixing with water
- For carrier-oil blends in aromatherapy, it mixes completely with jojoba, sweet almond and fractionated coconut oils
- Recommended dilution for aromatherapy: 1-2% in carrier oil for adults; 0.5% for massage blends used over large body areas
