Dunaliella Salina Extract ●
TL;DR. It is used primarily as a skin-conditioning antioxidant extract, often added for carotenoid-rich color and to support formulas against oxidative stress in the oil phase or on the skin surface.
What does Dunaliella Salina Extract do in a cosmetic formula?
It is used primarily as a skin-conditioning antioxidant extract, often added for carotenoid-rich color and to support formulas against oxidative stress in the oil phase or on the skin surface.
Is Dunaliella Salina Extract clean?
Clean-beauty frameworks generally view this ingredient as low-concern when it is preserved and extracted with accepted solvents. The main watchouts are individual sensitivity, preservation system compatibility, and residual solvent documentation.
Is Dunaliella Salina Extract sustainable?
It is sourced from cultivated biomass grown in high-salt water, so it can use non-arable land and reduce reliance on freshwater-intensive crops. It is expected to be biodegradable, with footprint driven mainly by cultivation energy, drying, extraction, and solvent recovery.
Is Dunaliella Salina Extract COSMOS-approved?
This ingredient can be permitted under COSMOS-natural and COSMOS-organic when the source, extraction solvents, processing aids, and preservation system meet the standard. It fits Green Chemistry best when made by physical extraction or approved solvents such as water, ethanol, glycerin, or plant oils, with good biodegradability and solvent recovery.
How does Dunaliella Salina Extract work chemically?
This material is a complex extract rather than a single molecule, with carotenoids such as beta-carotene and xanthophylls carried in a water, glycerin, oil, or alcohol matrix. Use levels are commonly low in leave-on care, often about 0.1 to 2%, and carotenoids are sensitive to light, heat, and oxygen, so opaque packaging, antioxidants, and cool processing help preserve color and activity.
