Alginic acid salt and hemostatic material containing same

Abstract

The present invention aims to provide an alginate with a higher hemostatic effect than conventional alginates. The alginate of the present invention contains a calcium salt of a carboxyl group and a different carboxyl (salt) group, wherein, provided that a structural unit containing the calcium salt in a repeating unit (structural unit) constituting the alginate is calcium alginate, a structural unit containing the different carboxyl (salt) group in the repeating unit is sodium alginate, and the alginate is regarded as a mixture of the sodium alginate and the calcium alginate, the alginate has a mass percentage of the calcium alginate (calcium content) of 1 to 99% by mass.
