ABSTRACT:
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.
