It is permitted under COSMOS-natural and can be used in COSMOS-organic formulas when produced from eligible agricultural raw material by approved physical extraction. It fits Green Chemistry reasonably well through renewable sourcing and solvent-free processing, with the main caveats being agricultural inputs, distillation energy, and allergen management.
How does Rosmarinus Officinalis \ Rosemary\ \ Leaf Oil work chemically?
This material is a complex mixture of volatile terpenes and oxygenated terpenoids, commonly including 1,8-cineole, camphor, alpha-pinene, borneol, and verbenone, with composition varying by chemotype and origin. Use levels are usually low, often below 1% for scent, and it should be protected from heat, light, and air because terpene oxidation can increase sensitization.
