Plasticized PVC is a common material for medical gloves. Due to vinyl gloves having less flexibility and elasticity, several guidelines recommend either latex or nitrile gloves for clinical care and procedures that require manual dexterity and/or that involve patient contact for more than a brief period. Vinyl gloves show poor resistance to many chemicals, including glutaraldehyde-based products and alcohols used in formulation of disinfectants for swabbing down work surfaces or in hand rubs. The additives in PVC are also known to cause skin reactions such as allergic contact dermatitis. These are for example the antioxidant bisphenol A, the biocide benzisothiazolinone, propylene glycol/adipate polyester and ethylhexylmaleate.
