Synthesised from benzene. A white, water-insoluble powder used
predominantly against Penicillium fungi growing on citrus fruits.
It is used to disinfect containers and in impregnating the wrapping
of citrus fruits. Sometimes fruits are dipped in a solution
of biphenyl, which slowly penetrates the peel and may be present
in the fruit itself. Typically found impregnated into citrus
fruit wrappers to prevent post harvest diseases.
It is excreted unaltered by the kidneys. Sensitivity has been
reported for people handling large consignments of citrus fruits
Used for agricultural purposes (an aromatic fungicide), it
is a skin and eye irritant.
Biphenyl is a constituent of the wood preservative creosote.
Not recommended for consumption by children.
