How soluble is this lemongrass oil in different media?
This lemongrass oil is insoluble in water but freely soluble in ethanol and fixed oils. The ISO 3217 general-grade solubility is 1 volume of oil in 3 volumes of 70% (V/V) ethanol at 20°C; the East Indian type (ISO 4718) is even easier to dissolve at 1:2 in 70% ethanol, and the DB45 domestic type dissolves clearly at 1:0.9 in 95% ethanol.
Solubility Profile
| Medium | Solubility | Note |
|---|---|---|
| Water | Insoluble | Oil separates; use a solubiliser for aqueous products |
| Ethanol 70% (V/V) | 1 vol in 3 vol (ISO 3217); 1:2 East Indian (ISO 4718) | Standard diluent for perfumery |
| Ethanol 95% (V/V) | 1 vol in 0.9 vol (DB45) | Clear solution |
| Fixed oils | Fully miscible | Carrier oils, massage blends |
| Propylene glycol / DPG | Soluble in practice | Cosmetic systems |
| Aqueous systems | Needs solubiliser (e.g. polysorbate) or the oil will separate | Beverage and room-spray bases |
- For beverages and food flavouring, dissolve the oil in ethanol or a food-grade solubiliser before adding to the aqueous phase
- For perfumery, the 70% ethanol solubility is the classic benchmark used to check authenticity and blendability
- Because the oil is fully miscible with fixed oils, massage and body-care formulations are straightforward
