Abstract
Abstract An improved surgical glove, powdered to serve as a lubricant, is provided by using a polyol powder as the lubricant. The use of a polyol powder as the powdering agent for use on surgical gloves avoids the problem of starch peritonitis that has been reported upon in medical literature. In one preferred application, polyol powder is dusted onto the side of the glove that will be the glove exterior, or patient-contact surface of the glove when used. Alternatively, polyol powder is dusted onto both surfaces of the glove.
