Rosmarinus Offinialis CO2 Extract ●
TL;DR. This ingredient is primarily used as a botanical antioxidant, helping slow oxidation of oils and other unsaturated lipids in formulas. It can also contribute light aromatic and skin-conditioning properties.
What does Rosmarinus Offinialis CO2 Extract do in a cosmetic formula?
This ingredient is primarily used as a botanical antioxidant, helping slow oxidation of oils and other unsaturated lipids in formulas. It can also contribute light aromatic and skin-conditioning properties.
Is Rosmarinus Offinialis CO2 Extract clean?
It is generally accepted in clean-beauty frameworks, but it carries botanical and fragrance-sensitization caveats depending on its volatile fraction. It is typically more of a low-level formula support ingredient than a bland, high-dose skin active.
Is Rosmarinus Offinialis CO2 Extract sustainable?
This material is plant-derived, and supercritical carbon dioxide extraction uses a recyclable solvent with minimal solvent residue. It is expected to be biodegradable, while its overall footprint depends on cultivation practices, origin traceability, and agricultural inputs.
Is Rosmarinus Offinialis CO2 Extract COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when the agricultural source and extraction process meet the standard’s requirements. It fits Green Chemistry well because the extraction method can reduce petrochemical solvent use, and the resulting material is renewable and biodegradable.
How does Rosmarinus Offinialis CO2 Extract work chemically?
This ingredient is a lipophilic botanical extract rich in phenolic diterpenes such as carnosic acid and carnosol, with composition shaped by the extraction pressure, temperature, and selected fraction. It is commonly used at low levels, often around 0.02% to 0.5%, and performs best in oil phases where it can help stabilize oxidation-prone lipids.
