Carrageenan ●
TL;DR. This ingredient is used mainly as a natural thickener, gelling agent, and stabilizer in gels, creams, lotions, and toothpastes. It helps build viscosity, suspend particles, and improve slip without acting like an oil-based conditioner.
What does Carrageenan do in a cosmetic formula?

Is Carrageenan clean?
Clean frameworks generally accept it because it is algae-derived, low-irritation for most users, and not a common restricted-list material. The main quality discussion is molecular size, since degraded low-molecular-weight fractions are not the same as normal cosmetic-grade material.
Is Carrageenan sustainable?
This material is sourced from farmed or wild-harvested red seaweed, so it can be renewable when managed responsibly. It is biodegradable and does not raise the persistence concerns associated with many synthetic film-forming polymers.
Is Carrageenan COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when made with accepted extraction and purification methods. It fits Green Chemistry well through renewable marine biomass, water-based processing, low volatility, and biodegradability.
How does Carrageenan work chemically?
This material is an anionic, sulfated polysaccharide that hydrates in water and forms viscosity through polymer entanglement and ion-mediated gel networks. Typical use is about 0.1% to 2%, with best stability near mildly acidic to neutral pH and reduced stability under strong acid plus heat.
