Carrageenan is made up of sodium, potassium, magnesium and calcium sulfate esters of galactose and 3,6-anhydrogalactose units. It is a wholly natural ingredient obtained from certain species of the red seaweed, class Rhodophyceae. Popular sources for carrageenan are the Chondrus crispus, Eucheuma cottonii and Eucheuma spinosum species.

Medical uses
A 2006 in vitro study and a 2007 mouse study at the National Cancer Institute in the United States suggested that carrageenans might function as a topical microbicide. A 1987 in vitro study in Spain revealed a broad spectrum antiviral activity of carrageenan.
