2.1.8.2. Absorbency Under Load (AUL) - BADA

According to our results, the swelling capacity of IZP-superabsorbent hydrogel was successfully
developed with excellent capability in normal saline and synthetic urine. Also the swollen IZP
hydrogel holds suitable amount of normal saline and urine under pressure (1-4 kPa). Because the
IZP-hydrogel was shown the high swelling rate at initial time so it can be used in several cosmetic
formulations as humectants. In detail the zygomycetes and albumin protein-based superabsorbents
are hydrolytically degradable, and the results of degradation are non-toxic amino acid derivatives,
so they are useful as controlled -release transdermal drug for internal and external applications.
5. Future Works
In fact, the results and details of AP and IZP superabsorbent hydrogels were quite investigated
during this research work, but future work can be developed for variety products by improving
features of superabsorbent via copolymerization, graft-polymerization or conjugation with various
natural or synthetic polymers and nanoparticles. As follow, many of the further and emerging
applications of superabsorbents can be obtained by chemical modification of functional groups in
order to extend in various purposes. The multi-element nature of such this systems offer
adaptability in terms of both biodegradation and mechanical properties.
Also, a similar approach can be used on other proteins, such as microbial proteins, animal proteins,
and proteins recovered from food-processing wastes.
