Cadexomer Iodine is a uniquely formulated starch matrix formed into spherical, highly absorbent microbeads containing 0.9% elemental iodine.

The Cadexomer is a 3D cross - linked polysaccharide starch matrix. The 0.9% iodine is physically bound to the cadexomer matrix and is only released when it is required.

Wound fluid and exudate are absorbed into the cadexomer beads of the Cadexomer Iodine, allowing the iodine to be released slowly. Please refer to the animation below.

When Cadexomer Iodine is applied to the wound surface, exudate, pus and debris are absorbed into the cadexomer beads. The beads will swell resulting in the formation of a demonstrable gel.

The presence of exudate and the consequent swelling of the beads results in the cross-linked bonds of the cadexomer matrix breaking and the iodine being released into the surrounding wound environment. When the iodine is released, the amount of iodine released will be to a level such that the concentration of iodine in the dressing and the wound environment reach an equilibrium. The equilibrium will remain and no further iodine will be released until the balance is disturbed.

Once the iodine in the surrounding wound environment has been depleted, more will be released from the product until the equilibrium is reached again and will remain until disturbed. This process will continue until all the 0.9% iodine within the product has been exhausted. The conversion of iodine is also associated with a color change from orangey brown to white. Therefore once all the iodine has been converted and utilized, the IODOSORB^◊ or IODOFLEX^◊ will appear white in color. At this point it is time to make a dressing change.
