Benzoyl Peroxide - Rats fed a diet containing benzoyl peroxide for 2-years showed an increased incidence of
Remarks
testicular atrophy at the highest dose (2800 mg/kg) that may have been due to the destruction of tocopherol in
the diet by benzoyl peroxide. Benzoyl peroxide was tested for carcinogenic potential in rats and mice in a
number of studies by life-time skin application of dietary feeding, as well as subcutaneous injection or
implantation. It was not carcinogenic in any of these studies. However, repeated long-term skin application
of benzoyl peroxide along with a known carcinogen (7,12-dimethylbenz[a]anthracene) has enhanced skin
tumor production changes in standard test using animals. Both positive and negative responses occurred in
tests with animal or bacterial cells. In vitro and in vivo radiolabel metabolism studies have shown that benzoyl
peroxide is absorbed into the skin and converted to benzoic acid which is excreted though the kidneys.
Butyl benzyl phthalate - Repeated oral and inhalation exposure caused increased mortality, eye irritation,
clinical signs of stiff hind limbs, reduced body, spleen and testes weights, increased liver and kidney weights,
anemia and pancreatic damage in rats. No effects other than reduced weight gain were seen in treated mice.
Birth defects were noted in the offspring of rats and mice exposed during pregnancy, but only at levels that
produced adverse effects on the mother. No increase in birth defects or maternal toxicity was seen in rabbits.
Decreased fertility was observed in rats following repeated administratin in the feed. In male rats study
revealed this product caused malformations in the reproductive organs. No genetic changes were observed
in tests using bacteria or animal cells, although changes were seen in animals.
