Permeability of nitrile rubber, latex, polyurethane, and neoprene gloves to 18 antineoplastic drugs.
The permeability of four glove materials to various antineoplastic drugs was studied. Eighteen antineoplastic drugs posing potential health hazards to handlers were prepared at the highest concentrations normally encountered by hospital personnel. Four glove materials-nitrile rubber, latex, polyurethane, and neoprene-were exposed to the drugs for 30, 60, 90, and 120 minutes. Glove thickness was measured with an electronic digital caliper. Random samples of material were selected from the glove fingertips, and triplicate samples were tested for each drug at each interval. For a majority of the drugs, a bacterial mutagenicity assay was used to measure the amount of drug (if any) that permeated the material. High-performance liquid chromatography was used for drugs not tested with the bacterial assay. The nitrile gloves were the thinnest (0.12 mm), and the latex gloves were the thickest (0.18 mm). The four materials were generally impermeable to each drug. One sample of the nitrile gloves appeared to have a defect, allowing >5% of the drug solution to pass through at 30 minutes. One sample each of the latex, polyurethane, and neoprene gloves demonstrated minimal permeability (< or =1%): One latex glove sample was permeated by carmustine, and paclitaxel permeated one sample each of the polyurethane and neoprene materials. Nitrile rubber, latex, polyurethane, and neoprene gloves were impermeable to 18 antineoplastic drugs in most, but not all, cases.
