κ-Carrageenan NEW

CAS No. : 11114-20-8

Formula: C24h36o25s2

EINECS: 232-524-2

Carrageenan is obtained by aqueous extraction of natural strains of seaweeds of Gigartinaceae, Solieriaceae, Hypneaceae andFurcellariaceae, families of the class Rhodophyceae (red seaweeds).  No organic precipitant shall be used other than methanol ethanol and propane-2-ol.  Carrageenan consists chiefly of the potassium, sodium, magnesium and calcium salts of polysaccharide sulphate esters which, on hydrolysis, yield galactose and 3,6-anhydrogalactose.  Carrageenan shall not be hydrolysed or otherwise chemically degraded.  Through scientific extraction, it has been widely used in food, medicine,personal care chemicals and so on.
