Study of aniline's penetration capability through rats' complete skin in vitro and normal lab gloves

Abstract

To study the permeability of intact mouse abdominal skin to aniline and the protective capability of two typical lab gloves against aniline. A Franz diffusion cell was used to perform in vitro transdermal absorption test and glove permeation test for aniline (0.102 mg/ml and 0.010 mg/ml). The permeabilities of intact mouse abdominal skin and gloves to aniline were measured by high performance liquid chromatography-diode array detection. The transdermal penetration of the two concentrations of aniline followed zero order kinetics within 12 h, exhibiting total aniline permeabilities within 24 h of 51.71% and 48.31%, respectively. The absorption liquid had an aniline concentration of at least 18 µg/L. The medical disposable latex glove could not stop the penetration of 0.010 mg/ml aniline, but the industrial natural latex glove could. The penetration of 0.102 mg/ml and 0.010 mg/ml aniline through the mouse abdominal skin follows zero order kinetics within 12 h. The medical disposable latex glove cannot stop the penetration of 0.010 mg/ml aniline, but the industrial natural latex glove can.
