How soluble is this Sichuan pepper oil in different solvents?
Sichuan pepper oil is freely soluble in ethanol and fixed oils, and insoluble in water — a classic monoterpene-rich essential-oil behavior that guides formulation.
Solubility Profile
| Solvent | Solubility | Formulation note |
|---|---|---|
| Water | Insoluble | Requires solubilizer (e.g., Tween/polysorbate) or pre-dilution for aqueous systems |
| Ethanol / alcohol | Freely soluble | Standard carrier for flavor and fragrance concentrates |
| Fixed oils (almond, jojoba, MCT, etc.) | Freely soluble | Direct carrier-oil dilution for massage and body-care blends |
| Glycols (PG / DPG) | Soluble | Common perfume-oil carrier and candle base |
| Isopropyl myristate | Soluble | Cosmetics and personal-care dilution |
- For water-based products (beverage emulsions, gels), pre-disperse in polysorbate at 1:1 to 1:3 before addition
- For candle making, dissolve in fragrance oil (IPM/DPG) at the recommended rate before pouring
- A standard 1–5% dilution in 95% ethanol yields a crystal-clear hydro-alcoholic solution
