RESUMO
OBJECTIVE: To study the permeability of intact mouse abdominal skin to aniline and the protective capability of two typical lab gloves against aniline. METHODS: 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. RESULTS: 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. CONCLUSION: 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.
