  • Clear, elastic, water gels based on carrageenan
    Patent number: 3962482
    Abstract: Clear, elastic, water gels and gel-forming compositions are based on potassium-sensitive carrageenan in the form of an alkali metal or an ammonium salt and a water-soluble potassium salt. Addition to the composition of calcium-sensitive carrageenan, also in the form of an alkali metal or an ammonium salt, imparts freedom from syneresis. The water gels and the gel-forming compositions are characterized by essentially complete freedom from polyvalent metal cations.
