Refined carrageenan has a 2% maximum for acid-insoluble material and is produced by alcohol precipitation or potassium chloride gel press process. [19] Semi-refined carrageenan has a much higher cellulose content [21] and is produced in a less complex process. Indonesia, the Philippines, and Chile are three main sources of raw material and ...
Carrageenan may prevent HPV and HSV transmission, but not HIV. See Carrageenan#Medical Uses.
