What does Rosemary Extract do in a cosmetic formula?
This ingredient is used mainly as an antioxidant botanical extract, helping slow rancidity in oils and supporting formula freshness. It can also add mild skin-conditioning and soothing claims.
Is Rosemary Extract clean?
It is generally accepted by clean-beauty frameworks and is not a common restricted-list concern, but aromatic plant constituents can be sensitizing for some users. Brands usually manage this through low use levels and supplier allergen documentation.
Is Rosemary Extract sustainable?
This material is plant-derived and renewable, with good biodegradability expected for its non-polymeric botanical constituents. Its footprint depends on farming practices and extraction solvent, with water, ethanol, glycerin, or oil-based extracts generally fitting lower-residue processing.
Is Rosemary Extract COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when made from approved plant material and allowed extraction solvents. It aligns well with Green Chemistry when sourced renewably and extracted with water, ethanol, glycerin, or carbon dioxide, while solvent choice and standardization additives determine the final fit.
How does Rosemary Extract work chemically?
This material is a complex mixture of phenolic diterpenes, phenolic acids, flavonoids, and volatile terpenes, so its activity depends on extract type and standardization. Use levels commonly sit around 0.05% to 1% for antioxidant or skin-conditioning support, and it is usually most effective when protected from heat, light, and excess oxygen in the finished formula.
