SMTL Dressings Datacard

Product Name: Kaltocarb
Classification Name: Dressing Calcium/Sodium Alginate with Activated Charcoal
Manufacturer: ConvaTec Ltd


Kaltocarb consists of an absorbent fibrous fleece of calcium sodium alginate (see Kaltostat) bonded to a layer of activated charcoal cloth with an outer layer composed of spun bonded viscose. The dressing combines the highly absorbent, gel forming properties of Kaltostat with the odour absorbing properties of activated charcoal.


Kaltocarb is indicated for use as a primary dressing in the management of malodorous wounds including fungating carcinomas, leg ulcers, and pressure sores. Although not specifically contra-indicated, Kaltocarb will be of little value if applied to wounds that are dry, or covered with hard black necrotic tissue.


Known sensitivity to Kaltocarb or its components.

Method of use

Kaltocarb is placed onto the surface of the wound with the charcoal layer uppermost. A secondary dressing is then applied which is held in place with surgical tape or a bandage. Kaltocarb can be removed with forceps or the gloved fingers. If necessary, removal may be facilitated by first moistening the dressing with sterile normal saline.

Frequency of Change

On non-infected, malodorous wounds, Kaltocarb may be left undisturbed until the dressing becomes saturated or until exudate strikes through the secondary dressing (typically 2-3 days). On infected wounds, the dressing should be changed daily.


The dressing should be changed daily on wounds that show evidence of clinical infection.


Kaltocarb is presented individually wrapped in a peel pouch, sterilised by gamma irradiation.
