Hexachlorophene was administered subcutaneously to pregnant STS mice on days 3-8,7-12, or 11-16 of gestation at levels of 0 (DMSO control), 12.5 and 25 mg/kg/day. The females were sacrificed on the 19th day and the fetuses were examined for viability and external abnormalities. Implantations and resorbtions were recorded. All the concentrations of the chemical were found to increase fetal resorbtion and mortality. Examinations of fetuses from the control groups and the experimental groups failed to reveal any teratogenic effects of hexachlorophene.
