Product Usage
Carrageenan finds applications in two main areas: food and industry. Food-grade carrageenan is used as a safe and compliant food additive, while industrial-grade carrageenan is applied in non-food sectors such as cosmetics (for thickening facial masks and smoothing hair conditioner films), pharmaceuticals (as gel bases for topical applications and for suspending drugs in oral liquids), and the textile and paper industries (for thickening printing pastes and enhancing water-resistant paper sizing).
