Unlock the natural benefits of carrageenan in your pharmaceutical application

Carrageenan is a naturally occurring family of hydrophilic polysaccharides extracted from several related red seaweed species, widely used as a gelling agent for controlled drug release.

Our Gelcarin® and Viscarin® controlled-release polymers include three basic types of carrageenan – kappa, iota and lambda. Available in several grades, Gelcarin® and Viscarin® help to achieve desired gelling, thickening and stabilizing properties in modified-release and suspension applications formulations – simply find the grade that’s best for you.
