MODIFIED STARCH COMPOSITION, METHOD OF MANUFACTURING SAME AND METHOD OF USING SAME

摘要

Absorbable dusting powders suitable for medical applications such as lubricating surgical gloves are prepared by treating starch with a hypochlorite to remove protein and oxidize some of the hydroxyl groups, and partially cross-linking the hypochlorite-treated starch with phosphorus oxychloride. The modified starch dusting powders are free flowing and are characterized by a protein content of less than about 0.15% by weight, hydroxyl groups oxidized to a level of from about 0.5 to about 0.05% by weight and a degree of cross-linking of other hydroxyl groups characterized by bound phosphorus levels of from about 200 to about 1200 ppm.
