Rosemary Oleoresin
Rosemary Oleoresin (Natural Antioxidant for Oils, Balms and Creams (ROE))
Our Rosemary Oleoresin, also known as Rosemary Oil Extract or ROE, is an oil-soluble extract of rosemary leaves (INCI: Rosmarinus Officinalis Leaf Extract). Its antioxidant action comes largely from carnosic acid, and ours is standardised to about 7% carnosic acid, so it is effective at very low rates.
Makers add it to oils and oil-based products to slow rancidity and help extend shelf life. It is a thick liquid, so it is best pre-dispersed in a small portion of the oil first. It is an antioxidant, not a preservative against bacteria and mould.

How to Use Rosemary Oleoresin in Oils and Balms
- Start fresh. Use oils that are fresh, before oxidation has started. An antioxidant can slow rancidity, but it cannot reverse it.
- Weigh. Weigh the oil. A common starting point is about 0.1-0.5% rosemary oleoresin (0.1-0.5 g per 100 g of oil), up to a maximum of 1%.
- Pre-disperse. Mix the oleoresin into a small portion of the oil first, warming it slightly if needed, because it is thick and sticky.
- Combine. Add this to the rest of the oil and stir thoroughly until it is evenly mixed.
- Add to creams. In creams and lotions, add it at cool-down together with your preservative.
- Pack and store. Pour into clean, dry, dark containers and store them in a cool place.
Tip: Use a clean, dry spoon or pipette and wipe the bottle neck. The oleoresin is thick and sticky, and any spills can stain.
Using It in Your Formulas ▼
These are common maker starting points, not fixed rules. Results vary with your recipe, so always test a small batch first.
| Use | Starting amount | Notes |
|---|---|---|
| Carrier oils | About 0.1-0.5% | Pre-disperse in a little of the oil, then mix through the rest. |
| Balms and butters | About 0.1-0.5% | Add to the melted oils and mix well before pouring. |
| Sugar and salt scrubs | About 0.1-0.5% | Mix into the oil first, then into the scrub. |
| Creams and lotions | About 0.1-0.5% | Add at cool-down, together with your preservative. |
| Soap oils | As set by your recipe, up to 1% | Test for colour and scent in the finished bar. |
These are starting points for makers, not fixed rules. Results vary with your oils and recipe, so test a small batch and keep to 1% or less.

| Problem | Likely cause | What to try |
|---|---|---|
| Oleoresin will not mix in | It is thick and sticky | Pre-disperse in a small amount of warm oil, then add to the rest. |
| Product has a dark tint | Natural dark colour of the extract | Use the lowest effective rate, or accept a slight tint in light products. |

| Oil still goes rancid | Oil was already oxidised, or heat, light and air exposure | Start with fresh oil, store in dark, cool conditions and keep containers closed. |
| Water-based product spoils | Rosemary oleoresin is not a preservative | Add a suitable preservative to anything that contains water. |
| Stains on skin or surfaces | Dark, sticky extract | Wipe up promptly. Keep it away from fabric and benchtops. |
