Claims14
A medical hydrogel comprising nanofibrillar cellulose, wherein the hydrogel has a viscosity in the range of 2500-9000 Pa·s, such as 3000-8000 Pa·s, for example 4000-7000 Pa·s, and a water retention value in the range of 30-100 g/g, such as 30-60 g/g, preferably 40-50 g/g.
A method for preparing a medical hydrogel, the method comprising
- providing pulp, such as wood pulp,
- optionally modifying the pulp, for example anionically or cationically,
- disintegrating the pulp until nanofibrillar cellulose is obtained,
- forming the nanofibrillar cellulose into a hydrogel, wherein the hydrogel has a viscosity in the range of 2500-9000 Pa·s, such as 3000-8000 Pa·s, for example 4000-7000 Pa·s, and a water retention value in the range of 30-100 g/g, such as 30-60 g/g, preferably 40-50 g/g.
