Is Salvia Rosmarinus Extract clean?
It is generally well accepted in clean-beauty standards, with the main caveat being possible sensitivity in very reactive skin because it contains aromatic plant constituents.
Is Salvia Rosmarinus Extract sustainable?
It is plant-derived from a cultivated perennial crop and is generally expected to biodegrade readily. Sustainability depends on farming practices, solvent choice, and concentration method, with ethanol, water, or carbon dioxide processing preferred.
Is Salvia Rosmarinus Extract COSMOS-approved?
It is permitted under COSMOS-natural and can count in COSMOS-organic when the agricultural feedstock and processing meet the standard. It fits Green Chemistry well when made with renewable feedstock, lower-impact solvents, and minimal purification burden.
How does Salvia Rosmarinus Extract work chemically?
This material is a complex botanical mixture rich in phenolic diterpenes and phenolic acids, including carnosic acid, carnosol, and rosmarinic acid, which donate hydrogen atoms to interrupt lipid oxidation. Typical cosmetic use is low, often about 0.05 to 0.5 percent, and performance is strongest in oil phases or emulsions where it can pair with tocopherol or chelators for broader oxidation control.
