Phaeodactylum Tricornotum Extract ●
TL;DR. This ingredient is used as a skin-conditioning active, mainly for antioxidant support, barrier comfort, and a smoother hydrated feel. In formulas, it is usually positioned as a bioactive extract rather than a structural emulsifier, preservative, or cleansing agent.
What does Phaeodactylum Tricornotum Extract do in a cosmetic formula?
This ingredient is used as a skin-conditioning active, mainly for antioxidant support, barrier comfort, and a smoother hydrated feel. In formulas, it is usually positioned as a bioactive extract rather than a structural emulsifier, preservative, or cleansing agent.
Is Phaeodactylum Tricornotum Extract clean?
From a clean-beauty perspective, this ingredient is generally low-friction when the extraction solvent, preservative system, and residual impurities are well controlled. Sensitivity risk is usually tied more to the finished extract blend than to the source material itself.
Is Phaeodactylum Tricornotum Extract sustainable?
It is typically derived from cultivated marine biomass, which can be a lower-land-use source of cosmetic actives compared with many terrestrial crops. Its sustainability profile depends on cultivation energy, water management, extraction solvent choice, and whether the biomass is produced in controlled systems.
Is Phaeodactylum Tricornotum Extract COSMOS-approved?
It can be permitted under COSMOS-natural, and under COSMOS-organic only when the source, processing method, extraction solvents, and preservatives meet the standard. It fits Green Chemistry best when produced from renewable biomass using water, glycerin, ethanol, or other approved benign solvents, with readily biodegradable carrier systems.
How does Phaeodactylum Tricornotum Extract work chemically?
This is a complex biological extract containing carotenoids such as fucoxanthin, lipid fractions including omega-3 components, amino acids, minerals, and polysaccharide material, so composition varies by strain, cultivation, and extraction method. It is commonly used at supplier-directed low percentages, often under 5%, and carotenoid-rich fractions benefit from protection against heat, light, and oxygen.
