Title:
ALGINIC ACID SALT AND HEMOSTATIC MATERIAL CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2023/248876
Kind Code:
A1
Abstract:
A purpose of the present invention is to provide an alginic acid salt superior in hemostatic effect to conventional alginic acid salts. This alginic acid salt has a carboxyl-group calcium salt and another carboxyl (salt) group, and is characterized in that, when structural units containing the calcium salt group, among the repeating units (structural units) constituting the alginic acid salt, are referred to as calcium alginate and structural units containing the other carboxyl (salt) group are referred to as sodium alginate and when the alginic acid salt is regarded as a mixture of the sodium alginate and the calcium alginate, then the mass proportion (calcium content) of the calcium alginate is 1-99 mass%.
