This paper reported the results of skin absorption and distribution of unguent and solution of [2-
14
C] carbendazol (MBC) in rats by using radioactive tracer and autoradiography. It was concluded as: 1) the percentage permeated into skin for unguent was 5.7%
while for solution 9.8%; 2) permeability constant for unguent was 1.86×10
-6
cm/h
while for solution 29.3×10
-6
cm/h; 3) carbendazol remained mainly in stratum corneum.
