1-42. (canceled)
A diaper, comprising γ-polyglutamic acid absorbent, wherein:
- the γ-polyglutamic acid is crosslinked with sorbitol polyglycidyl ether, wherein the amount of sorbitol polyglycidyl ether is about 1-3% of the total weight of γ-polyglutamic acid and sorbitol polyglycidyl ether;
- Mn of the γ-polyglutamic acid before crosslinking is about 0.6-0.7 million Da when assessed according to Procedure B in Example 1;
- absorption under load of the γ-polyglutamic acid is about 10 or more g/g under 0.7 psi when assessed according to EDANA WSP 242.2;
- and
- centrifugal retention capacity of the γ-polyglutamic acid is about 20 g/g or more when assessed according to ISO 17190-6.
