Abstract
A flexible burn dressing product contains a high absorbency hydrogel material in a gel phase. The hydrogel material is formed from a hydrogel composition for use in a wound dressings. The hydrogel composition is formed from a mixture comprising: (a) from about 0% to about 90% by weight polyhydric alcohol selected from the group consisting of polypropylene glycol, polyethylene glycol and glycerine; (b) from about 6% to about 60% by weight aliphatic diisocyanate terminated prepolymer based on polyols containing more than about 40% polyethylene oxide and having an isocyanate content of about 3% by weight; (c) from about 4% to about 40% by weight polyethylene oxide based polyamine; (d) up to about 2% by weight sodium chloride; and (e) the balance water. Such a hydrogel material provides a highly absorbent material capable of retaining large amounts of wound exudate, thereby rendering it very suitable for use in wound dressings.
