Corallina Officinalis \ Seaweed\ Extract ●
TL;DR. This ingredient is primarily a skin-conditioning marine extract that adds minerals, polysaccharides, and trace components to support hydration, softness, and product feel. It is usually used as a claims-supporting active rather than a structural emulsifier or preservative.
What does Corallina Officinalis \ Seaweed\ Extract do in a cosmetic formula?
This ingredient is primarily a skin-conditioning marine extract that adds minerals, polysaccharides, and trace components to support hydration, softness, and product feel. It is usually used as a claims-supporting active rather than a structural emulsifier or preservative.
Is Corallina Officinalis \ Seaweed\ Extract clean?
From a clean-beauty perspective, it is generally well accepted and has no common restricted-list friction. The main quality questions are extract variability and supplier testing for metals, iodine, microbial load, and solvent residues.
Is Corallina Officinalis \ Seaweed\ Extract sustainable?
This material is marine-derived and biodegradable in its organic fraction, but sourcing matters because calcified coastal biomass can play an ecological role in intertidal habitats. DARE would look for responsible harvest documentation, traceability, and routine contaminant screening.
Is Corallina Officinalis \ Seaweed\ Extract COSMOS-approved?
It can be permitted under COSMOS-natural and COSMOS-organic when obtained through approved physical processes or allowed extraction solvents, with compliant preservation and harvesting practices. Its Green Chemistry fit is strongest when made with water, glycerin, or other accepted benign solvents from a traceable renewable source.
How does Corallina Officinalis \ Seaweed\ Extract work chemically?
The extract is a complex mixture rather than a single molecule, typically containing sulfated polysaccharides, amino acids, phenolic compounds, and a notable calcium carbonate and magnesium mineral fraction from a calcified cell-wall matrix. Typical use is about 0.1% to 5% as supplied, often added in the water phase at cool-down, with stability driven by the carrier solvent, preservation system, and final formula pH.
