Carrageenan Extract ●
TL;DR. This ingredient primarily acts as a natural thickener, gelling agent, film-former, and emulsion stabilizer in water-based beauty and personal care formulas.
What does Carrageenan Extract do in a cosmetic formula?
This ingredient primarily acts as a natural thickener, gelling agent, film-former, and emulsion stabilizer in water-based beauty and personal care formulas.
Is Carrageenan Extract clean?
It is generally well accepted in clean-beauty frameworks, with low topical irritation potential and no major restricted-list friction. Cosmetic grades are high-molecular-weight materials, which are assessed differently from degraded low-molecular-weight forms discussed in some ingestion-related literature.
Is Carrageenan Extract sustainable?
This ingredient is sourced from renewable marine biomass and is readily biodegradable. Supply quality depends on responsible harvesting or farming practices, but its overall environmental profile is favorable compared with persistent synthetic polymers.
Is Carrageenan Extract COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic standards when sourced and processed as an allowed natural polymer. It aligns well with Green Chemistry because it is renewable, water-processable, biodegradable, and typically does not require harsh solvent chemistry.
How does Carrageenan Extract work chemically?
This material is an anionic sulfated galactan polymer, and its viscosity or gel strength depends on sulfate pattern, molecular weight, salts, and hydration conditions. Typical cosmetic use is about 0.1% to 1.5%, with best performance after full water hydration and reduced stability under strongly acidic, high-heat conditions.
