A wound dressing comprises a free-flowing, anhydrous particulate material, which on contact with water forms a water-soluble hydrogel. The particulate material is preferably a cellulose derivative and may include a wound healing therapeutic agent such as growth factors or antibiotics. At least 50% of the particles by weight will pash through a mesh of size 18 (1mm). In use the particulate material is sprinkled onto a wound where it absorbs the exudate and forms a gel which can be removed by washing. |
