The powder absorbs the blood from scarps and mild wounds while creating a soft, gel-like cover. This layer comes together over the wound and stops the bleeding immediately. "Blood-Stop Plus" spray is hypoallergenic, has a balanced pH, is fast-acting and is not sticky. "Blood-Stop Plus" spray is not an adhesive spray-on plaster, but a powdered first aid spray.
