Why this grade
This is not a marketing antioxidant — it is a formulation-protection workhorse. 75% total phenolic fraction from CO2 extraction, dominated by carnosic acid, extends rancidity thresholds in oil phases by factors, not percentages.
For brands moving away from BHT and tocopherol-only systems, our rosemary extract is the natural alternative with real induction-period data behind it. We supply peroxide-value curves in finished oil bases on request. Use at 0.02-0.2%.
Key benefits
- 75% phenolic fraction, carnosic-acid dominant profile
- Documented induction-period extension in common oil bases
- CO2 extraction — no ethanol residues, low color contribution
- Clean-label replacement for BHT / TBHQ systems
Technical specification
Ingredient profile
Rosemary extract is the natural antioxidant of choice for oils, butters and anhydrous systems, and this material is standardized to 75%-plus total phenolics with carnosic acid reported per lot — the two numbers that actually predict antioxidant performance.
Produced by a solvent-free CO2 process, the batch COA carries a zero residual-solvents result, which matters for clean-label claims and for formulators who test for extraction residues.
Typical use is 0.05–0.5% in oil phases, balms and body butters, where it visibly slows rancidity. It is vegan, COSMOS-ready and allergen-free, with full micro results on the batch COA.
