Expanding Use of Superabsorbent Polymers in Personal Care Products The polymer class known broadly as Superabsorbent Polymers (SAPs) exhibits extraordinary fluid‑absorption, retention and swelling behaviour, making them indispensable in applications requiring efficient fluid management, immobilisation or release. These materials are typically three‑dimensional, cross‑linked networks of hydrophilic polymer chains—commonly based on polyacrylic acid, sodium...
