Abstract Skin covering materials especially for wounds comprise dextran C insolubilized by reaction with epichlorohydrin in combination with a suitable humectant. The compositions may be in the form of coherent, self-supporting sheets of the insolubilized dextran C impregnated with humectant material, or in the form of pastes applied to the wound as such. The humectant material is preferably glycerin or isopropanolpropylene glycol and an oil. The wound covering material allows sufficient removal of exuded body fluid and seals the wound site against bacterial infection, whilst at the same time maintaining the wound moist to prevent scale formation. Medicaments may additionally be incorporated into the wound covering material, to assist in healing and further to safeguard against bacterial infection.
A wound covering material comprising epichlorohydrin insolubilized dextran C polysaccharide sheet impregnated with a humectant for application to skin wound for covering and protection thereof.
