Rosmarinus officinalis extract ●
TL;DR. This ingredient is used mainly as an antioxidant extract, helping slow rancidity in oils and protecting formulas from oxidative color or odor changes. It can also contribute light skin-conditioning benefits in leave-on products.
What does Rosmarinus officinalis extract do in a cosmetic formula?
This ingredient is used mainly as an antioxidant extract, helping slow rancidity in oils and protecting formulas from oxidative color or odor changes. It can also contribute light skin-conditioning benefits in leave-on products.
Is Rosmarinus officinalis extract clean?
This ingredient is broadly accepted in clean-beauty frameworks and is not a common restricted-list concern. Because it is an aromatic plant extract, trace fragrance constituents can matter for very reactive skin, so supplier allergen documentation and use level are relevant.
Is Rosmarinus officinalis extract sustainable?
This material is plant-derived and generally biodegradable, with a renewable sourcing profile. Its footprint depends on cultivation practices, extraction solvent choice, and concentration method.
Is Rosmarinus officinalis extract COSMOS-approved?
It is permitted in COSMOS-natural products when made with approved extraction solvents and compliant preservation, and it can fit COSMOS-organic products when the agricultural source and processing qualify. It aligns well with Green Chemistry when produced with water, ethanol, glycerin, or supercritical carbon dioxide, although concentrated extracts require added processing energy.
How does Rosmarinus officinalis extract work chemically?
The molecule profile is a mixture of phenolic diterpenes, phenolic acids, and volatile trace components that quench oxidation by hydrogen donation and radical stabilization. Typical use is often about 0.05% to 1% as supplied, with stability influenced by light, heat, oxygen exposure, solvent system, and the antioxidant strength of the standardized extract.
