• Description:
  The hypothesis was that multiple layers of disposable nitrile gloves would protect longer against 2-butoxyethanol (2-BE) than a single layer relative to standardized breakthrough time (SBRT) and steady state permeation rate (SSPR). Many industries such as aerospace, automotive, recycling, and waste disposal facilities utilize 2-BE. The resistance of disposable blue powder- free nitrile gloves (Kimberly-Clark) against 2-BE was tested in single, double, and triple layers. The American Society for Testing and Materials (ASTM) Method F739-12 for permeation resistance under continuous contact was used. For each run set, four 1-inch diameter permeation cells (three cells with 10 mL 2-BE as challenge and one air blank (1)) were used with 10 mL deionized water as the collection solvent in a water bath shaken at 72.3 +/- 0.58 revolution/minute (4.82 +/- 0.04 cm/second) at 35.0 +/- 0.5 degrees C. 0.1 mL aliquots were sampled at 5, 10, 20, 30, 40, 50, 135, 240, 360, and 480 minutes. Capillary column gas chromatography-mass spectrometry (GC- MS) utilized mass to charge ratios 2-BE at m/z= 57 and 87, and 4-bromophenol (4-BP) internal standard at m/z= 174 (1). The retention times for 2-BE and 4-BP were 4.8 min and 7.9 min. SBRT were found between 5 to 10 minutes for single, between 10 to 20 minutes for double, and between 30 to 40 minutes for triple layers, though thus not statistically different at p ≤ 0.050. Single gloving had a rating of 'poor,' while double and triple gloving were 'good,' based on Kimberly Clark Professional permeation breakthrough time criteria. The other statistically different comparison was for the mass/area permeation at 30 minutes for the triple layer relative to a single layer. The average SSPR were 41.20 +/- 8.81 ug/cm2/min for single gloving, 48.48 +/- 55.57 ug/cm2/min for double gloving, and 5.39 +/- 4.64 ug/cm2/min for triple gloving. Both single and double gloving had a rating of good, and triple gloving had a rating of very good based on Ansell permeation rate criteria for Chemical Resistant Gloves. Thus, multiple layers did tend to prolong SBRT, but only triple layers definitely lowered the SSPR. Description provided by NIOSH
