Greater sensitivity of detecting glove defects using soap solution and the role of non-rubber constituents in needle puncture tear

The higher percentage of failure in the palm region of commercial gloves than in the fingers was partly attributed to the sensitivity of the 1 litre water leak test rather than merely to the higher number of defects in the palm. Incorporating 0.1% sodium dodecyl sulphate, Teepol®, TritonX-100® or Tween-80® in water increased the sensitivity of detecting finger defects. The smallest leak detectable by the 1 litre soap leak test was equivalent to 2 µL virus phi X174 penetration. Needle punctured NR gloves exposed to cyclic stress offered a better protection than vinyl and nitrile gloves under similar conditions. The non-rubber constituents present in NR gloves were shown to have some effect on the amount of virus penetrating through the punctured tear.
