PROBLEM TO BE SOLVED: To provide the subject powder composed of a sugar, a water-swelling cellulose compound, a binder and an iodophor, having excellent fluidity and water-absorptivity, easily absorbing and removing the exudate from wound surface and giving low stimulation to the wound. SOLUTION: This powder is composed of (A) 60-80wt.% of a sugar (preferably sucrose), (B) 20-40wt.% of a water-swelling cellulose compound (preferably a hydroxypropylcellulose having low substitution degree), (C) 0.5-3.0wt.% of a binder (preferably a hydroxypropylcellulose) and (D) 0.5-10wt.% of a iodophor (preferably povidone iodine). The powder can be produced preferably by mixing the component A with the component B, adding a solution produced by dissolving the component C in a lower alkanol (e.g. methanol) to the mixture, kneading, drying and granulating the product and mixing with the component D.
