What is the solubility profile of this Astragalus root oil?
Astragalus root oil is soluble in ethanol and fixed oils, and practically insoluble in water.
Solubility Summary
| Solvent / system | Solubility |
|---|---|
| Ethanol 95% | Soluble (clear to slightly hazy in most proportions) |
| Fixed oils (jojoba, almond, MCT) | Fully miscible / soluble |
| Dipropylene glycol / PEG | Soluble with gentle warming |
| Water | Practically insoluble |
| Surfactant / emulsifier systems | Dispersible when properly emulsified |
- Because of its waxy nature, warming to 30–40°C and gentle stirring is recommended before dissolving into carriers
- In fine-fragrance formulas it is typically dosed into the ethanol concentrate rather than the water phase
- For cosmetic emulsions, add into the oil phase with emulsifier support for a stable result
