Abstract
An ostomy bag insert (104) comprising a polyacrylate superabsorbent (300) and a powdered zeolite (301). The ostomy bag insert is configured to absorb fluids excreted by the body and to control odours resultant from the excreted matter within the ostomy bag (100). The present zeolite exhibits enhanced odour control.
