It is unknown what, if any, effect on pregnancy many of the chemicals have because teratogenicity (causing damage to a fetus) testing in these products has not usually been reported. In the work that has been done, some compounds, such as aminophenol, were not teratogenic when tested in rats. In contrast, some hair dye preparations have been associated with birth defects in mice. It should be remembered that testing typically involves feeding large amounts of the test substance to the animals. The extent to which these results are predictive of effects from topical exposure in the human is unknown.
