Background
Cobalt is a gray, hard, magnetic, ductile, somewhat malleable metal. It
is used in the manufacture of alloys and cobalt salts. It is an essential
trace mineral and is present in vitamin B12.
Various salts of cobalt are colored and are used as pigments in colored
glass and pottery as well as in makeup and hair dyes.
Approximately 80% of individuals sensitive to cobalt are also found
to be sensitive to either or both chromate and nickel.
Probably the most common source of exposure to cobalt is nickel-plated
objects, which practically always contain cobalt.
Patch testing with cobalt chloride may yield an unusual false-positive
response consisting of tiny purpuric papules.
