carrageenan

polymer

Carrageenan is a natural polysaccharide polymer extracted from red seaweed, belonging to the family of hydrocolloids and gelling agents. It is widely used in the food industry as a thickener, stabilizer, and gelling agent in dairy products, meat processing, and plant-based beverages, valued for its ability to form viscous solutions and firm gels without chemical synthesis. Beyond food, carrageenan finds applications in pharmaceuticals, cosmetics, and specialty coatings where controlled rheology and biocompatibility are advantageous; engineers select it over synthetic alternatives when natural origin, food-grade certification, or biodegradability are project requirements.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
