Cobaltous 2-ethylhexanoate (cobalt octoate) is an accelerator in the polyester resins. There have been several reports of allergic contact dermatitis resulting from cobaltous 2-ethylhexanoate. It was demonstrated, that cobalt octoate induced DNA strand breakage in vitro (in human cells), but the damage appeared to be explained by oxidative damage resulting from reactive oxygen species, probably caused by the cobalt cation.
