Investigation of hexachlorophene for dominant lethal effects in the mouse.
Hexachlorophene (HCP) was studied for mutagenic effects in the dominant lethal test on mice. Groups of male mice were treated with either 2.5 or 5.0 mg hexachlorophene per kg body weight as a single intraperitoneal injection. Control animals were treated with the propylene glycol vehicle. Each male was mated with 3 untreated females for each of 8 consecutive weeks with the uterus of the females examined at mid-pregnancy for signs of early embryonic death. Treatment did not alter mating capacity and fertility of the males. The administration of hexachlorophene had no influence on pre- or post-implantation losses. An increase in early resorptions among female mice bred to males treated with the reference compound, methyl methanesulfonate (MMS) given a single i.p. injection of 100 mg/kg, indicated the susceptibility of the mouse strain used to a known mutagen. It is concluded that hexachlorophene at maximally tolerated doses is not mutagenic in the dominant lethal test in mice.
