Rosemary CO2 (Oleoresin)

Price range: $10.50 through $32.00 USD

INCI: Rosmarinus Officinalis (Rosemary) Leaf Extract

Use: 0.02% – 0.1%

Rosemary CO₂ Oleoresin (ROE) is a powerful, oil-soluble antioxidant extracted from rosemary leaves using supercritical CO₂ extraction. This gentle, solvent-free method preserves the full spectrum of rosemary’s antioxidant compounds—particularly carnosic acid and carnosol—which are known for their ability to prevent rancidity in oils, butters, and lipid-rich formulations.

Ideal for formulators looking to extend the shelf life of natural products without synthetic preservatives, ROE is a go-to natural stabilizer used in everything from facial oils and body butters to balms and oil-based serums.

  • Prevents oxidation and rancidity in oil-based formulas

  • Extends shelf life of sensitive carrier oils and unsaponifiables

  • Highly concentrated, effective at low usage rates

  • Neutral aroma compared to essential oil versions

  • Safe for use in a wide variety of natural and organic formulations

  • Usage Rate: 0.02–0.1% (depending on oil type and sensitivity)

  • Solubility: Oil-soluble

  • Phase: Add to oil phase during formulation, ideally below 40°C

  • Storage: Store in a cool, dark environment to preserve efficacy

  • Compatibility: Ideal for carrier oils, COâ‚‚ extracts, emulsions (oil phase), and anhydrous products

Technical Notes:

  • Not a preservative (does not protect against microbial growth)

  • Effective in preventing lipid oxidation in both natural and conventional formulations

  • Slight coloration may occur at higher concentrations—test in clear packaging

 

  • Facial and body oils

  • Balms and salves

  • Oil-based serums

  • Emulsions with high lipid content

  • Cold-pressed oils with short shelf life (e.g., rosehip, flax, borage)
