Nanofibrillar cellulose (NFC) for biomedical and pharmaceutical applications are typically obtained with disintegration processes that result in grades of NFC or chemical processes that result in contaminating materials, which are not desirable for all applications. The present disclosure relates to a high pressure mechanically disintegrated nanofibrillar cellulose having an average degree of polymerization greater than 1000, and a storage modulus between 0.3 and 20 Pa, when dispersed to a concentration of 0.5 w% in water, which can be used in biomedical and pharmaceutical applications in the form of a hydrogel or membrane, as well as to methods of obtaining same. |
