A hydrophilic foam composition comprising the in situ reaction product of an isocyanate-capped polyether prepolymer, a hydrophilic agent capable of absorbing water, an adjuvant comprising an alcohol, a wetting agent, and water. The composition releasably carries the adjuvant and will release at least a portion of the adjuvant in the presence of an external liquid so that the liquid can be absorbed and carried by the foam composition. The composition is particularly useful in wound dressings and composites for use in such dressings. |
