What is the solubility profile of this Chuanxiong rhizome oil?
Chuanxiong oil behaves as a classic phthalide-rich essential oil: freely soluble in ethanol and fixed oils, and practically insoluble in water.
Solubility Profile
| Solvent / system | Behavior |
|---|---|
| Ethanol 95% and absolute alcohol | Clear, complete dissolution |
| Fixed oils (jojoba, almond, MCT, sunflower) | Fully miscible in all proportions |
| DPG / PEG glycols | Soluble, with gentle stirring |
| Water | Practically insoluble (classic oil-on-water separation) |
| Surfactant / emulsifier systems | Readily dispersible in properly emulsified cosmetic bases |
- As a mobile liquid oil it dissolves easily without heating, unlike waxy root oils
- For aqueous products (lotions, scalp tonics), pre-dissolve in a solubilizer (e.g. PEG-40 hydrogenated castor oil) or oil phase before emulsifying
