Carrageenan
Carrageenan is a naturally occurring polysaccharide extracted from red seaweed.
Carrageenan has three types, Iota, Kappa, and Lambda. Iota Carrageenan forms flexible and elastic gel; Kappa Carrageenan forms strong and brittle gel; Lambda Carrageenan creates viscosity. Each type has unique properties useful in controlled release matrix formation.
