Actisorb Plus comprises of a charcoal cloth consisting of 95-98% carbon, produced by carbonising and activating a knitted viscose rayon fabric. The rayon fabric is enclosed in a sleeve of spun-bonded non-woven nylon, sealed along all four edges, to facilitate handling of the dressing and to reduce particle and fibre loss.

When used as a dressing, activated charcoal has the ability to adsorb toxins and wound degradation products as well as volatile fatty acids responsible for the production of wound odour.
