How soluble is this perilla leaf oil in different solvents?
Soluble in ethanol and fixed oils; insoluble in water. For formulation work the oil dissolves readily in perfumer's alcohol (ethanol), dipropylene glycol, and common carrier oils.
Solubility Profile
| Solvent | Solubility | Note |
|---|---|---|
| Ethanol (perfumer's alcohol) | Soluble | Clear solutions at typical fragrance dilutions (10–20%) |
| Fixed oils (jojoba, sunflower, etc.) | Soluble | For massage and topical blends |
| Dipropylene glycol / glycols | Soluble | Perfumery & household fragrance systems |
| Water | Insoluble | Emulsifiers or solubilizers needed for aqueous systems |
- For aqueous products (rinses, sprays), pre-dissolve in a solubilizer such as polysorbate or HP-β-cyclodextrin
- Perillaldehyde itself shows limited water solubility (about 630.9 mg/L at 25°C), which matches the oil's water-insoluble character
- Always test final clarity in your specific base before scale-up, as solubility varies with ethanol strength and additive load
